calculator with x HTML in minsIn this article you won t see the millionth way of writing a calculator with the tools that are well covered by many others Instead I m going to show you how to do it with much less effort in a tool you probably haven t heard of yet And it is a big deal since it automates and abstracts away frontend web app development by the ways you ve seen elsewhere And yeah the calculator is a trivial app yet it s a good example to present a few interesting concepts OK enough of the intro here are few steps to follow Go to Create a new project Write the below code you can click preview to see changes as your e typing Export it to a self contained app based on SolidJS and JSX lt DOCTYPE html gt lt html lang en gt lt head gt lt meta charset UTF gt lt meta name viewport

uiSignals numberB break case default props value uiSignals numberA uiSignals numberB lt script gt lt input x gt lt div gt lt div gt lt div gt lt body gt lt html gt What just happened Well the above code certainly wouldn t work if you dropped it into a regular HTML file In a traditional way you d need to have a script below the document and manually query for an element and then update it It could work in a small app which you don t plan to extend But if you need your UI to be reactive and at the same time maintainable you d opt for some reactive framework or library Perhaps JSX so your UI looks like HTML but it can be interpolated with dynamic data in a declarative fashion That can be done beautifully with SolidJS and it will diff DOM at build time as opposed to what many other frameworks libraries do i e using Virtual DOM It s all great but wouldn t it be cool to use HTML where possible and extend it to be reactive where necessary This is exactly what you see in the code above It s a combination of extended tags and UI signals to mange the local state At GlueCodes we introduced extended tags which are named tagName x and have an embedded lt script gt allowing you to access variables available in the scope where they have been placed The scripts can assign to props variable to change props attributes of the extended tag In this case you can see writing reading uiSignals which holds some sort of observables and it ll update any props they are assigned to What you see is a meta framework abstracting away the signals See SolidJS Notice the uiSignals are scoped to a slot partial they are in and an HTML tag is told to be a slot by using one of many HTML directives lt div gc as slot gc name content gt lt div gt So in addition to extended tags you can make your HTML dynamic by using attribute directives as you would in modern web frameworks When typing most of them you ll get notified to auto create if don t exist required actions or to install a widget The vocabulary here is simple an attribute gc as tells what it is and other gc attributes are parameters The above code can be split into parts An embedded script tag in each of the extended tag allows to modify their props e g register events or set a value on an input It modifies only the props of its direct parent tag Capturing the first number lt input x type number gt lt script gt props onChange e

海外TECH	DEV Community	Optimizing performance of PHP app that sends an external request	https://dev.to/nostop8/optimizing-performance-of-php-app-that-sends-an-external-request-291p	Optimizing performance of PHP app that sends an external request Table Of ContentsIntroOptimization Iteration Optimization Iteration Optimization Iteration Exposing more infoSummary Intro I m running web services API written in PHP and one of the endpoints during every request pings another external web service particularly Firebase Realtime DB which in its turn can deliver notification to the client through the Websockets API Below is the image with a rough architecture of this process As you can see any client app browser and any server app some rd party can send a request to the PHP endpoint then PHP pings the Firebase endpoint and finally the Firebase notifies the client app browser about intercepted request Web service short storyThe web service I am running is not very complicated and we can divide the operations is does into the following steps Processing requestDoing few SQL queries including insert queriesPerforming POST request to the external Firebase Realtime DB APIProviding response to the clientAfter it was completed I did load tests and profiling It turned out that posting data to Firebase was taking around seconds Therefore number of requests that could be performed simultaneously to my own PHP endpoint was around minute with the response time of more than seconds PHP app time Firebase request time This was a very poor result so I started to look into improving the performance and particularly the request time to Firebase A bit of side talkYou might know that any VM is generally limited by main factors CPU and Memory When it comes to these limitations a very important aspect is the time a relevant time value to our VM capacity that is required for our application to run in a specific environment The faster our app runs or in other words the more optimized it is the more simultaneous instances of our app can be executed This is especially valid for the PHP scripts Optimization Iteration First of all it turned out that the Firebase PHP SDK was making requests all the time First request to get the access token and second to actually post the data I found out that there s a way to use a “database secrets which is a one time generated token that you may use to access your Firebase DB So I just dropped the SDK and used a direct request using CURL interface provided inside the PHP The time to post data to Firebase decreased approximately by second So now I could perform requests per minute and the response time was around seconds This is better than previous but still not good enough The reason why Firebase request was taking so long is because PHP waits for the response from the remote server due to its synchronous code execution nature So all the subsequent code is blocked until the response is received This piece of functionality with Firebase notifications is not very critical to my application and in case for any reason something goes wrong during the request to Firebase there s no need to perform some rollback and I do not actually need to know about it immediately etc Thus I decided to speed up the performance by omitting the part where PHP is waiting for the response from the remote server The PHP should just send a request and does not care about what happens afterwards Optimization Iteration To solve this task I used a simple solution where you can execute external CLI commands using PHP And yes cURL does has a CLI interface tool We may present the updated architecture on the diagram below The PHP code combined with the cURL command looks the following way cliCommand lt lt lt CODEcurl k H Content Type application json d hello world X POST https lt my db gt firebaseio com lt my endpoint gt json auth lt database secret gt gt gt tmp firebase log gt amp amp CODE exec cliCommand This part gt gt tmp firebase log gt amp amp allows to omit the response waiting code blocking and instead log it inside the firebase log file in case I need to check for any possible error later which I implemented later using a cronjob task This simple solution made the endpoint working almost instantly The response time from the PHP script dropped from seconds to ms and now I could perform around simultaneous requests per minute…Really I was expecting a bit more Something was definitely wrong here When I checked the htop tool CPU and memory monitoring tool I found out that during the load test curl tools literally eats all the CPU of CPU power was filled with CURL tasks I m not really sure why this little command line application is “so hungry for the computation power If you know please drop a message in the comments below Optimization Iteration Anyway I started to search for some alternatives Among CLI tools there s nothing better than curl So I ve decided to try another interface particularly HTTP interface by experimenting with NodeJS Express Javascript is an asynchronous programming language and Node runs it very efficiently along with Express I ve created a small JS script using extra libraries Express and HTTP It is basically an asynchronous proxy that listens for HTTP requests and forwards data to Firebase Realtime DB endpoint Because we access the NodeJS script through the HTTP interface instead of using exec method on the PHP side I had to switch to sockets particularly to fsocketopen fwrite and fclose Sockets allow to send ping requests from PHP without waiting for the response You might want to ask why in the hell I need the NodeJS then Well if I use fsocketopen for sending request directly to the remote web server Firebase in a different network and region and for sending request to the local web server NodeJS that sits on the same machine ーthat s totally different things in terms of timing Also I can run my local Express server without SSL but Firebase can run using only HTTPS thus fsocketopen would have to spend additional time to send an extra background request for the SSL handshake Thus yes there s a great benefit in using fsocketopen in order to simply open some another thread on some different local interface Anyway this is the new architecture diagram I came to And here are the performance optimization results CPU load went down from to max The memory was almost on the same level roughly The response time was ms And finally the number of simultaneous requests I could execute to the endpoint skyrocketed up to requests per minute Exposing more info Testing EnvironmentFinally revealing the environment I used for those tests It is EC t micro instance CPU and GB of memory BTW MySQL DB is on the separate VM instance which saves the VM resources greatly For load tests I was using Apache jMeter and a default thread properties which are number of threads users equals to ramp up period equals to second Code snippetsPHP script that sends request to the NodeJS script using the fsocketopen url http localhost prod or http localhost dev urlParts parse url url try fp fsockopen urlParts host urlParts port errno

express json app post function req res postFirebase req originalUrl substr JSON stringify req body res set Content Type application json res json Listen on port app listen function err if err throw err console log Server started on port Summary To summarize there s always a room for improving and optimizing the code and its efficiency I ve managed to improve the time required to run the API endpoint from seconds to x times As for the number of simultaneous requests the improvement is more than x times from requests per minute and up to NodeJS performed much better than a CLI s curl tool in terms of consuming CPU and memory resources Therefore the pair of “fsocketopen NodeJS works much better than “exec curl if you want to initiate another thread from within the PHP to ping some external resource or web service Thanks for reading Please let me know if you have an idea why curl requires so much of CPU resources to send requests comparing to NodeJS Also it is interesting if there s any other good option instead of NodeJS to create a small proxy over the HTTP protocol to send requests asynchronously e g Python and do you think it can perform better Thanks ahead for your thoughts P S This article was also posted on my another blog here	2021-05-24 20:08:07
海外TECH	DEV Community	Friendly Intro to Document Oriented Databases	https://dev.to/kalashin1/friendly-intro-to-document-oriented-databases-2dkm	Friendly Intro to Document Oriented DatabasesChoosing a database for your application is a critical and important part of software development cycle There is no shortage of database options that you can chose and this just adds more complexity to the whole process Personally i use Document oriented databases most of the time and this doesn t mean that Document oriented databases are the best solution for your database all the time they do come with some albeit a few drawbacks but i think the benefits outweighs the drawbacks One type of database you could use alternatively is Relational Databases I recently made an article about Relational Databases and if you missed that you can go over it here What are Document Oriented DatabasesDocument oriented database are a type database that allows you to organize and store your data into documents The documents represent an individual record in our data A document is just an object with key value pairs If you are familiar with JavaScript a document is similar to an object literal Or a dictionary in python Each document must belong to a collection which in itself is just a reference to one or more documents that looks alike You can think of it like this a collection is a folder that holds multiple documents while documents are just files inside the collection that contains the actual data Conceptually a collection is similar to a MySQL table while documents are similar to the rows on a table The keys on each document represents the columns each document can have one or more keys The keys holds a value which is usually of any type e g strings numbers dates arrays objects e t c The main take away here is that instead of defining how the data should look like on the collection like we do in a relational database with a table each document actually specifies what it looks like that is why we define keys on the document However this doesnt mean that we can be haphazard and do whatever we like we have to ensure that each collection is consistent with the type of document stored inside to prevent errors when we are updating or retrieving data from the database A typical example of a document oriented database collectionA typical example of a document oriented database document Benefits Of Document Oriented DatabasesDocument oriented database are developer friendly they allow you to organize store and retrieve your data in a format that is compatible with how it is consumed basically what you get in the frontend is exactly how it looks in the backend albeit with some few changes so you don t need to write any data transformation logic keeping your database in sync with the frontend Most Document oriented database service providers allow for flexible payment method rather than a fixed system you get with SQL database and in fact you end up only paying for as much as you use i e you are billed as per a set number of document reads and writes for a given period saving you some extra bucks The best part is that most of the service providers have a free tier so you can even build some simple apps that utilizes this cool feature without worrying too much about paying any money initially Document Oriented database service providers actually give you this database as a service every other aspect of the database is automatically handled for you you don t need worry about data storage locations electricity scaling up your database equipment management and all of that jazz You can focus on what developers like to focus on and leave your worries not to God in this case but your document oriented database service providers These type of database comes with a query language that is quite easy to learn and use and allows you to do much more with just fewer lines of code Although i have enjoyed working with SQL the language is declarative and has a lot of keywords you need to remember we already have many frameworks and languages to worry about Most document oriented database have a query language that is expressive with few keywords and is actually implemented in a programming language you are already familiar with so you need not worry about having to learn a new language from scratch again You don t have to worry about normalizing your data and figuring out how one thing is related to another thing you do not have to separate information that deserves to be grouped together you can keep everything you need to be together together You only need to read a single document to get all the information you need which means faster load response time Personally i like keeping things together rather than in different places except of course there is no way around it Drawbacks of Document Oriented DatabaseI wont say that document oriented databases comes with only benefits and no pain in the neck there is some drawbacks to using document oriented database and the more common ones include A schema is not automatically created for you when you create a collection or add a document to a collection thus if you don t implement one you can be having documents with key value pairs that are not on other documents causing havoc when you want to retrieve or update data Data modeling is quite complicated with document oriented database because it is entirely up to you to choose how you want to model your data If you are a beginner programmer this can be a little too much for you and even if you are experienced you have to spend some time on the table doing some structuring Performing joins is actually quite difficult in document oriented database because from the ground up they are not designed to handle relational data so you would rely on your data modeling technique to work a way around this Document Oriented DatabasesFiresore This is a type of document oriented database that is provided by Google via Firebase it is very simple to use and work with Personally i have built a couple of web apps using firebaseb firestore and I m currently using it on a project MongoDB The world s most used document oriented database Mongodb is cloud database that is provided by the MongoDB organization it is a complete and robust database when combined with Mongoosejs you can easily negate some of the drawbacks of document oriented databases i don t say this very often but i recommend using it over Firestore Fauna DB This is a quite a new player in the document oriented database field and it offers more than just document oriented database because you can model relational data graph data e t c but it also keeps things simple and you can only model document data i pay a lot of attention to this database and i am planning on using it as my database solution for my next app That s for that today i hope you found this useful and you enjoyed reading it feel free to extend this with the benefits of document oriented database that makes you use them or one of the drawbacks that make you stay away from them You can also add other document oriented database service providers that you use	2021-05-24 20:06:27
