[2]	https://dev.to/adaendra/software-performance-testing-why-its-important-2-2jc2	Software performance testing Why it x s important In the first post we discover what is Software Performance Testing and a bunch of different types of tests Today we will see why it s important to do performance tests PrerequisitesBefore talking about why performance tests are important we need to talk about the prerequisites If you want to do this kind of test you need to know for each operation the accepted latencythe volume of transactions that you can have in a normal period and during peaksThese information must comes from the business line if your service is right behind a front end serviceand or by the aggregation of all the requirements for your consumers Also this informations must come before you start your analysis architecture for the following reasons Things included with Performance Testing ArchitecturePerformance testing is something that can t arrive late in a project It must be here at the beginning Otherwise how can you be sure to respect all the performance conditions For example if you are alone with one oven to cook some pies for a party and don t know how many people will come how will you do if people come The idea with development is the same Developing something which can support or TPS is not the same You won t use the same tools you won t orchestrate the calls in the same way especially if you are working in a big enterprise where some services can be older or limited for some reasons MonitoringIf you want to check what s happening when you are doing performance tests you will need to have something set up to monitor your services and your infra During the performance testing phase it will be useful to check bottlenecks and understand what is limiting your service AlertingNow that you know what are your limits about latency and volume you will be able to add some alerts to prevent if the load is close to the max With that you will be proactive and may avoid a production issue Why it s important to do Performance tests So finally why it s important to do Performance tests As you can see in the previous part doing these tests embed a lot of things that can only be beneficial for your system Also and it s the biggest reason why your system will be reliable With all these tests a correct architecture matching the needs monitoring alerting you will avoid a lot of issues related to loading And if you are close to your maximum your alerting will ping you to let you know that you have to do something before it s too late I hope it will help you And see you to the next part How to do it	2022-04-05 13:39:06
海外TECH	DEV Community	Building a Slack App with Native SFDC Integration	https://dev.to/salesforcedevs/building-a-slack-app-with-native-sfdc-integration-4m4m	Building a Slack App with Native SFDC Integration Building a Slack App Designing a UIThis post is a continuation of our series based on a video series explaining how to build Slack Apps that integrate with Salesforce APIs With the Slack Starter Kit from Salesforce Slack app developers can offload common concerns like Salesforce authentication directory hierarchies reusable code and deployments to Heroku The end result is less time spent wrangling code and more time building features for your app In our last post we familiarized ourselves with the starter kit and set up our development environment to build a basic Slack app In this post we ll continue building on that Slack app focusing on how the Slack Starter Kit makes it easy to develop two essential components of every Slack app Listening for user interactionsDrawing a user interface Responding to eventsIf you ve ever developed a front end web app using JavaScript or CSS you re probably familiar with the basic tenets of event handling Events in this context are defined as the actions a user takes on your website For example a mouse pointer clicking on a link emits an onclick event a pointer linking over a piece of text emits onhover a keyboard keystroke emits onkeypressed and so on Photo by Stephen Phillips Hostreviews co uk on UnsplashIn Slack there s a multitude of events you can listen to ranging from individual events when a message is posted or pinned to global changes when channel names or visibilities are changed to the administrative when an app is installed or a new emoji is uploaded The full list of emitted events is truly impressive The process for listening to an event is as follows First your app needs to define a webhook URL This is a path on your server which can receive POST requests from Slack Next in your App Manifest you identify the events which you d like to capture When an event occurs in a workspace where your app is installed a JSON payload is sent to your app Every event has its own unique payload When your app receives the event from Slack you can do anything you want respond to the user pop open a dialog to ask for more information or simply store some information away in your database There s only one important point to remember you must respond to Slack within three seconds This is to let Slack know that your app received its payload and is working on a response You can do that work in the backgroundーperhaps on a different thread taking as long as you needーbut only after you let Slack know everything is OK Let s take a look at how event handling works in practice Head on over to your App Manifest and scroll down to the bottom of the page near the settings key It should look like this settings event subscriptions request url https lt your app name gt herokuapp com slack events bot events app home opened interactivity is enabled true request url https lt your app name gt herokuapp com slack eventsThis section identifies where Slack should send its payload once an event occurs The bot events key already defines one event to listen to app home opened which is triggered once your app is opened in Slack Now open up the local copy of your Starter Kit in your IDE navigate to apps slack salesforce starter app listeners events app home opened js As we saw in the last post the Starter Kit has an opinionated directory structure to resolve any ambiguities as to where modifications should be made In this case the events folder is responsible for defining all of our event responses just like the shortcuts folder defined our slack command in the previous article Search for the first occurrence of the following line client views publishAs the method name implies this function uses a Slack SDK to call an API named views publish The main view for this event is created by a function called authorization success screen which can be found in apps slack salesforce starter app user interface app home auth success js Let s make a few changes to these files On line add this line to fetch the timestamp of the event let event ts event event ts Change both authorization success screen calls to include this variable as a new argument view authorization success screen currentuser username event ts Finally open up auth success js change the method signature to include event ts and modify the displayed string to include this information use strict const HomeTab Blocks require slack block builder const authorization success screen username event ts gt preceding code remains unchanged Blocks Section text It s event ts and you are successfully authenticated to Salesforce as username continued code remains unchangedCommit this change and deploy it to Heroku as before git add git commit m Add event timestamp git push heroku mainWhen the deployment is done navigate to your app s tab in the left hand Slack menu You should see a different string which shows the timestamp of when you opened the app Creating a UIResponding to app home opened can be a useful event to listen to whenever your app needs a centralized location to fetch data Because of this our next step will be to fetch data from Salesforce and present it in our Slack UI To design and present layouts Slack provides a system known as Block Kit Just as HTML is a markup language for the web and Visualforce is a markup language for Salesforce Block Kit is a markup language for Slackーexcept it uses JSON For example here s what a button designed in Block Kit might look like type button text type plain text text Save style primary Block Kit ensures that every Slack App has a consistent user interface Because of this there s a limited set of UI elements that you can use When working with Block Kit you design your layout in JSON Then you use the Slack API to POST that JSON to a channel tab or direct message We already have a system in place for listening to an event and presenting text so let s build on that foundation Before we work in Slack though let s add some data to our fresh Salesforce org To launch your browser directly to your Salesforce org you can run the following command sfdx force org openIn the Setup menu search for the Data Import Wizard Choose CSV as your data type then copy paste the following lines into a new file called data csv Contact First Name Contact Last Name Contact DescriptionArden Isabela Lorem ipsum dolor sit ametRowina Arti Proin a est sit amet quam varius efficitur Aislin Oedipus Praesent et euismod semSindri Filbert Proin facilisis sit amet libero vulputate sodalesCyril Gratien Nulla at massa eu turpis venenatis egestasUpload this file as your data source Importing this data should only take a minute or two You can navigate to the Contacts tab if you d like to be extra sure and verify that these names exist Next we re going to make changes similar to the ones we made before when adding the event timestamp A variable called conn is available to use which serves as a connection to Salesforce We can use it to query for Contact data which is what we re interested in displaying in Slack Navigate to apps slack salesforce starter app user interface app home auth success js We ll await the resolving of the promise in this function and we ll include the existing connvariable as a new argument view await authorization success screen currentuser username event ts conn And once again open up auth success js and change the method signature to include conn You also need to declare the function as async use strict const HomeTab Blocks require slack block builder const authorization success screen async username event ts conn gt continued code remains unchanged for nowNext with this connection we re going to issue a query to Salesforce to get our newly created Contact records We ll then display them in the Home tab of our Slack app Since we already have a connection to Salesforce fetching the data is as easy as issuing an SQL query Place this code right before the place where the homeTab variable is defined const result await conn query SELECT Name Description FROM Contact let records result records let fields records map record gt return record Name record Description Then at the bottom of the blocks method call add these lines which represent the UI you re constructing out of Block Kit Blocks Section text It s event ts and you are successfully authenticated to Salesforce as username Blocks Header text Contacts Blocks Divider Blocks Section text fields join n If you navigate back to your Slack App s Home tab you ll see your organization s list of contacts Learning moreWe ve built a Slack app that fetches data from Salesforce and presents that data in a UI using a framework called Block Kit In our next post we ll send data from Slack back to Salesforce Before then you might want to familiarize yourself with how Block Kit works Slack provides the Block Kit Builder which is a playground for their UI elements Under the hood the Slack Starter Kit uses the Block Builder to simplify the UI assemblage we worked with	2022-04-05 13:38:35

Geography with Geocod io amp Turf jsFor most of my geocoding needs Geocod io more than fits the bill Their API provides a fast and simple way to convert addresses into geographic coordinates get congressional or state legislative districts and much more I d recommend giving their API docs a read if you have an upcoming project that you need geocoding for Full disclosure I m NOT sponsored by Geocod io I just like using their service and it makes my life easier Despite all these great features there are some instances where we need to check against geographic boundaries that Geocod io doesn t have An example of this would be seeing if someone s address is inside a specific City or County Council district Fortunately we can use turf js to extend Geocod io s functionality to fit our own specific needs The foot overview To give you the gist of what we ll be doingt First we ll still use Geocod io to convert our Address into latitude and longitude coordinates Doing so allows us to take those coordinates and work with them through the turf js module Next we ll take the geoJSON file of our custom geography and use the node geojson module to extract the features more on these later into a format we can pass into turf js as a polygon Once we have those two things ready to go we ll use a turf js function booleanPointInPolygon to check if our coordinates is inside one of those polygons If that all sounds a bit confusing now don t worry things will make more sense once we see it in action and also once we start visualizing some of our spatial data The Code Let s start with a fresh project I m creating a new directory called turf tut to hold our working files in Create that directory then cd inside and run the following commands to install our dependencies npm install geocodio library node node geojson turf turfnpm install dotenv save devEverything should be pretty self explanatory here the only thing that might look a little weird is that we ll be installing dotenv as a dev dependency to store our Geocodio API Key It s a bad idea to hard code API keys Once that finishes installing update your package json file to add the following start script Your final package json should look something like this Note the version numbers to the right of your packages might be different from mine If you copy paste this entire json file you ll need to re run npm install which will reinstall all these packages from the package json file scripts start node r dotenv config index js dependencies turf turf geocodio library node node geojson devDependencies dotenv Create a env file and add the following line to it GEOCODIO API KEY HelloWorld Finally create an index js file and add the following code const GEOCODIO API KEY process env GEOCODIO API KEYconst Geocodio require geocodio library node const geocoder new Geocodio YOUR API KEY const geoJSON require node geojson const turf require turf turf async function main console log GEOCODIO API KEY main Now if we run npm start we should see the below response ❯npm start gt start gt node r dotenv config index jsHelloWorld Take note that since we called r dotenv config in our start script we could access those env vars through the process env object without having to configure that in our code You ll also notice that we re executing our code inside async function main this is to avoid issues with top level awaits a topic that I won t go into here Before we can dive into writing code we have final setup steps downloading some geoJSON data to work with and setting up a Geocod io account For geoJSON go to and select City Council Districts Clipped to Shoreline and click the globe that says GeoJSON You ll be redirected to a text webpage with the GeoJSON data save the data from that website or grab the file from the example repo Data Side Note When working with public data like this especially datasets that deal with things like legislative districts it s important to note that the possibility of the data being inaccurate or incomplete always exists Just be aware that nyc gov provides this data as is for informational purposes only as stated in their disclaimerFor Geocod io go to dash geocod io register sign up for an account then once you re logged in hit the API Keys button on the left hand sidebar then hit the Create an API Key button The only permissions we ll need are GET v geocode Give your key a name save it then you should be able to copy your key and paste it into the env file we created earlier in the GEOCODIO API KEY variable Let s return to our index js file and start building out our geocoder With your API Key now stored as a env variable we can update our index js change the Geocodio config line like below const geocoder new Geocodio YOUR API KEY lt Change thisconst geocoder new Geocodio GEOCODIO API KEY lt To this Then update our main function async function main var geoResponse await geocoder geocode City Hall Park New York NY console log JSON stringify geoResponse null var lng geoResponse results location lng var lat geoResponse results location lat var pt turf point lng lat console log Our coordinates are lng lat console log Our point is pt It s only a few lines of code but we have a lot going on here To start we create a variable geoResponse and set it equal to the value of the promise returned from geocoder geocode In the above code I supplied the address City Hall Park New York NY that is as you probably could assume the address for New York City Hall Next we console log the response I just used JSON stringify to make sure everything gets printed so you can see what the API response schema looks like you could also check the docs for this Then we extract the Longitude and Latitude from our geocoder geocode response and store them as variables Next we create a variable pt which we set as a turf point Note that the point function accepts a single array of Longitude Latitude Turf js uses the longitude first convention as does GeoJSON If you take those coordinates and plug them into Google Maps they ll need to be latitude first so it s good to keep track of this while we work Finally I console log our coordinates array as well as the turf point pt After running npm start again you should see an output similar to the following ❯npm start gt start gt node r dotenv config index js input address components city New York state NY zip country US formatted address New York NY results address components city New York county New York County state NY zip country US formatted address New York NY location lat lng accuracy accuracy type place source TIGER Linedataset from the US Census Bureau Our coordinates are Our point is type Feature properties geometry type Point coordinates Great we now have a means to convert an address into lng lat coordinates and convert that into a turf js point If you ll recall back to our ft overview that s one of the two input parameters we need for booleanPointInPolygon So let s now turn our attention to our geoJSON file If you haven t worked with geoJSON before it might be worth briefly familiarizing yourself I m by no means an expert on GeoJSON but I ll do my best to explain enough to get through our use case GeoJSON is valid JSON ie you can save the file as either a json or geojson however GeoJSON has a pre defined format for how its data should be structured which allow different applications to share GeoJSON between them Here s an example of GeoJSON data type Feature properties name Dinagat Islands geometry type Point coordinates If that looks familiar it s because our turf point from earlier is actually valid GeoJSON itself Taking a closer look at the geojson file you ll also notice that the first value type is equal to Feature In this case features refer to Simple Features which are things like points lines polygons multi points etc think back to high school geometry Additionally geojson files can have the type of FeatureCollection which again you probably guessed is comprised of a collection of Features FeatureCollection is the type of the NYC Councilmanic districts file that we downloaded earlier Another great tool is this online geojson editor courtesy of Tom MacWright You can either copy paste the contents of our geoJSON file onto that website or use the file upload feature to load it up After loading the file you ll see a map of New York City with various polygons overtop of city limits Each of those polygons is a distinct City Council district and is a geoJSON Feature See told you it d be easier to visualize If you try clicking on a specific polygon you ll see that geojson io shows a pop over tooltip with more info about that polygon This additional info is the properties value on our GeoJSON file In the below image I zoomed in on the map to City Hall and clicked the polygon to pull up the properties for that feature You can see that it has the properties OBJECTID CounDist Shape Area Shape Length The other properties geojson io adds so that you can change the polygon line amp fill colors etc Just disregard those The property that we re interested in is CounDist that refers to the number of the NYC Council District Side Note The properties Shape Area and Shape Length were included on the geoJSON file when we downloaded it GeoJSON doesn t automatically compute those values for you But Turf js has the area function that you could use to implement size calculation if you wanted Geojson io also has a nice feature Table view which further helps understand how our geojson data works If you click a cell in the Table view of our geojson file you ll see the map zooms you to be centered on that polygon You ll also notice that you can edit the contents of the cell I mentioned this earlier but the table view really highlights it the OBJECTID field Council District Turning our attention back to index js you can comment out our existing console log calls for now add the following new code inside our main function at the bottom var geodata await geoJSON createUsingFile nyc city council json var features geodata GetAllFeatures features forEach feature gt console log feature properties In this new section of code we re creating a new variable geodata and setting it s value to the return of geoJSON createUsingFile That does things it loads our geoJSON from file into memory so our application can manipulate the geoJSON file but we also get access to some nice helper functions from the node geojson module such as GetAllFeatures which we use in the next line to save each of the features from our geoJSON file into a new array And as we just saw each feature in our geoJSON is a file so when we call the forEach function over our features array we console log the properties of each feature which should be OBJECTID CounDist Shape Area Shape Length After updating the code and running npm start again you should see output like the following gt start gt node r dotenv config index js OBJECTID CounDist Shape Area Shape Length OBJECTID CounDist Shape Area Shape Length rest OBJECTID CounDist Shape Area Shape Length Finally update our features forEach loop to the following features forEach feature gt THIS IF ELSE IF VERY IMPORTANT if feature geometry type Polygon var poly turf polygon feature geometry coordinates else if feature geometry type MultiPolygon var poly turf multiPolygon feature geometry coordinates var isPointInPoly turf booleanPointInPolygon pt poly if isPointInPoly console log Your point is in Council District feature properties CounDist Once again we ve added only a few lines of code but there s a lot going on here So let s break it down The first thing we do is check if our feature is of type Polygon or MultiPolygon It is very important we run this check because if we try passing a MultiPolygon geoJSON feature to the Polygon turf js we ll get a confusing error message and spend a couple hours banging our heads against a keyboard until we figure it out Don t ask me why I know that Once we have our correct polygon type we then pass our point pt from earlier and polygon into the turf booleanPointInPolygon function That function again this is kinda obvious here checks if the point is inside the polygon and if so returns True Finally if we hit a match we console log back to the user which feature aka council district the match was in For clarity I saved the result of booleanPointInPolygon to a new variable but you could just as easily run the if check on the function itself From looking at the pdf map on the nyc gov site I know that City Hall should be in district but now for the moment of truth Can our app figure that out After saving index js run npm start one last fateful time gt start gt node r dotenv config index jsYour point is in Council District It s a thing of beauty Look out Uber Extra Credit If we really want to test how well our Geocoder does let s pull an address off Governor s Island to see if the MultiPolygon is really testing all the polygons Originally I wanted to use the address Statue of Liberty because the GeoJSON file from ny gov indicated it was also in Council District There were problems with that though Geocod io had a hard time converting the very non standard address into lat lng coordinates and The Statue of Liberty is technically in New Jersey so I don t know what that s included in the GeoJSON file Since resolving inter state disputes is also outside the scope of this tutorial I pulled the address for Taco Vista a TexMex restaurant at Carder Rd New York NY instead Sounds tasty Change line in index js to geocoder geocode Carder Rd New York NY then run npm start Once again Council District ConclusionGeoSpatial data can

further extension of this project would be to integrate it into Express js as a backend api then use Mapbox or leaflet js to build a frontend to display the points and polygons on a map	2022-04-05

海外TECH	DEV Community	The tale of the triathlete and C++ performance	https://dev.to/imaculate3/the-tale-of-the-triathlete-and-c-performance-1g7a	The tale of the triathlete and C performanceLet s solve the problem of the triathlete who wants to get a rough idea of their training efforts using C Given that running is twice as hard as biking and swimming is four times as hard as running she wants the weighted sum of all her activities provided as a list where an activity is made of distance and type There is enough clarity to the problem so lets get to it VThe most straight forward solution looks like the function below double calculateTriathleteEffortV vector lt int gt distances vector lt string gt types double result for int i i lt distances size i int distance distances i string type types i if type swim result distance else if type run result distance else if type bike result distance return result It sums up the activities distances weighted by respective factors It works just fine and runs in an average of microseconds per run over million runs If we have to calculate this for billions of athletes it will not scale V Bit ManipulationAn easy way to optimize this is by using replacing multiplication with bit shift operations This is possible because the factors are multiples of and bit shifts are generally faster than arithmetic operations double calculateTriathleteEffortV vector lt int gt distances vector lt string gt types double result for int i i lt distances size i int distance distances i string type types i if type swim result distance lt lt else if type run result distance lt lt else if type bike result distance return result The V function above runs in microseconds Surprisingly this optimization has made things worse The explanation lies somewhere in the assembly output The compile command below saves the intermediate files including the assembly file which we should examine g save temps fverbose asm test athlete cpp o test athlete exeThe instructions from V and V are practically the same so it looks like the compiler does a better job at this optimization than us test athlete cpp result distance movl rbp eax distance tmp sall eax test athlete cpp result distance cvtsisd eax xmm movsd rbp xmm result tmp addsd xmm xmm tmp tmp movsd xmm rbp tmp result jmp L test athlete cpp result distance lt lt movl rbp eax distance tmp sall eax test athlete cpp result distance lt lt cvtsisd eax xmm movsd rbp xmm result tmp addsd xmm xmm tmp tmp movsd xmm rbp tmp result jmp L We are therefore better off with multiplication so we have to look for the gains elsewhere V BranchesV branches between activity types using if else if statements where each if statement is processed in the arbitrary order we have set swim gt run gt bike even though each case is independent of the others Using switch case statements allows the compiler to generate jump tables which are faster We will attempt that and to do that we have to change the data type of activity type to enum because strings can t be used in switch case statements typedef enum RUN BIKE SWIM Type double calculateTriathleteEffortV vector lt int gt distances vector lt Type gt types double result for int i i lt distances size i int distance distances i Type type types i switch type case SWIM result distance break case RUN result distance break case BIKE result distance break return result This not only eliminates expensive if else if jumps also but string comparison of activity types and the results do speak for themselves V runs in an average of microseconds per run almost twice as fast This is definitely an optimization we want to keep Can we do better Probably lets try eliminating jumps altogether V BranchesWe can eliminate branches by using a look up table to translate activity types to multiplication factors typedef enum RUN BIKE SWIM Type int factors double calculateTriathleteEffortV vector lt int gt distances vector lt Type gt types double result for int i i lt distances size i int distance distances i Type type types i result distance factors type return result V runs in an average of microseconds per run marginally better than V The cost of jumps is replaced by array access which is only borderline faster Although marginal it is still faster we ll therefore carry it forward as we continue to look for more performance opportunities We have gone as far as we can to optimize the algorithm lets try tweaking the data structures V Constant vector referencesWe didn t give a lot of thought into the function API it accepts vectors which are passed by value even though they are only read in the function We can correct that bya Passing the vectors by reference this should shave some time that is spent copying all elements b Marking the vectors as constant to ensure the function doesn t change the original vectors double calculateTriathleteEffortV const vector lt int gt amp distances const vector lt Type gt amp types double result for int i i lt distances size i int distance distances i Type type types i switch type case SWIM result distance lt lt break case RUN result distance lt lt break case BIKE result distance break return result V runs in an average of microseconds per run almost x faster than V It might be hard to hard to top that but lets try changing the parameters from vectors to static arrays V Array parametersThere is no need to pass dynamically sized vectors when the size never changes Vector elements reside in the heap which makes access slower Alternatively accessing static arrays elements is faster because they are on the stack Arrays are passed to functions as pointers therefore we need not worry about copying on passing by value double calculateTriathleteEffortV int distances Type types int size double result for int i i lt size i int distance distances i Type type types i switch type case SWIM result distance lt lt break case RUN result distance lt lt break case BIKE result distance break return result V above runs in an average of microseconds per run almost twice as fast V and significantly faster than V We can probably do better but we ll stop here The table summarizes the gains or losses each version brought FunctionTime us Delta from previous Delta from V VV VVVVWe have witnessed a speedup of almost in our function applying very practical tweaks some of which didn t work It is therefore very important to measure if attempted optimizations are working The journey to performance doesn t end here there is probably more ways to make it run faster and a lot more ways to reduce the memory footprint Benchmarks and profiling should guide these decisions In the meantime our triathletes will definitely appreciate the runtime improvements	2022-04-05 13:27:45
海外TECH	DEV Community	How to Handle Reactivity in Svelte	https://dev.to/smpnjn/how-to-handle-reactivity-in-svelte-1p5k	How to Handle Reactivity in SvelteSvelte like most frontend frameworks is a reactive language That means data updates translate straight into UI updates Let s look at how reactivity works in Svelte If you re brand new to Svelte read my guide on getting started with Svelte here Reactivity in SvelteAt its most basic variables are generally reactive in Svelte For example creating a component like this will result in a live updating counter displayed within the button lt script gt let x const addToCounter function x lt script gt lt button id counter on click addToCounter gt x lt button gt lt style gt button background ffb border radius px border none font weight bold cursor pointer padding rem rem color white font size rem lt style gt Above x is increased by one every time the button is clicked We do this with on click addToCounter The x displayed in counter is automatically increased and displays the new value on every click In that way Svelte provides reactivity out of the box so it s really easy to intuitively understand what s going on Svelte also provides some more advanced reactivity features Reactive CalculationsIn some scenarios we want to update a value like x and then do a calculation on it We may then display that within our UI somewhere For example lt script gt let x let bigX x const addToCounter function x lt script gt lt button id counter on click addToCounter gt bigX lt button gt lt style gt button background ffb border radius px border none font weight bold cursor pointer padding rem rem color white font size rem lt style gt Above we want to show our calculated bigX value within the button tag which should equal x Upon clicking the button x will increase by one and therefore we d expect bigX to also react However in Svelte this will not work as calculated values like this aren t inherently reactive As such we need to tell Svelte that bigX should also react To do that we replace let with The below code will now update bigX every time x is updated and display it within our button lt script gt let x bigX x const addToCounter function x lt script gt lt button id counter on click addToCounter gt bigX lt button gt lt style gt button background ffb border radius px border none font weight bold cursor pointer padding rem rem color white font size rem lt style gt Reactivity Principles in SvelteSvelte intelligently understands that if bigX x and we want bigX to be reactive that it should only update if x is updated Reactive blocks in SvelteIn the same way that we can make independent variables run again whenever something within them changes we can do the same for block statements For example let s say we want to check if x is equal to If we write the following it won t do anything let x if x console log x is x const addToCounter function x That s because on initiation x is and the if statement only runs once If we want it to run every time x updates we add to the start let x if x console log x is x const addToCounter function x The same can be done with curly bracket block statements alone For example the below code console logs x any time it changes let x console log x const addToCounter function x Out of all the frontend frameworks Svelte perhaps makes reactivity the most easy If you ve enjoyed this article you can find more Svelte content here	2022-04-05 13:26:46
