海外TECH	DEV Community	Memoization using React.useMemo()	https://dev.to/hardiksharma/memoization-using-reactusememo-142h	Memoization using React useMemo First we need to understand what memoization is Memoization is an optimization technique in which we accelerate our programs by caching the results of heavy function calls for the same inputs In simple terms for example we have an input say and we pass it through our function which takes a lot of time to execute Now if we need to calculate the result for input again then we need to perform the function again and it will again take that much time But not if we used memoization in the first go if we memoize the output for of that function then we just need to get that value from our memoized values and don t need to execute that function again for which in term will save us the time it takes for execution and will make our program much more optimized In this post we will understand how to use useMemo React hook useMemo useMemo is a React Hook that lets you cache the result of a calculation between re renders It accepts arguments a function that computes a result and the depedencies array const memoizedValue useMemo calculateValue dependencies During initial rendering useMemo calculateValue dependencies invokes calculateValue memoizes the calculation result and returns it to the component If the dependencies don t change during the next renderings then useMemo doesn t invoke calculateValue but returns the memoized value But if the dependencies change during re rendering then useMemo invokes calculateValue memoizes the new value and returns it const memoizedResult useMemo gt return heavyFunction A B A B In this case we have two dependencies A and B so for the first render it will let the heavyFunction run to get the output but in the re renders if the dependencies don t change then it ll not execute the function and will return the memoized value ExampleLet s take example of a classic recursion problem of calculating a factorial In factorial we often have the same input and without memoization the function always keeps on going to calculate the result but if we memoize the output for a value and return that then we will save a lot of recursion cycles and will just return the memoized value at that point only function fact n if n lt return return n fact n So this is a simple implementation of factorial of a number n using recursion Now if we have a whole component for this import useState useMemo from react export function CalculateFactorial const number setNumber useState const factorial useMemo gt fact number number const onChange event gt setNumber Number event target value return lt div gt Factorial of lt input type number value number onChange onChange gt is factorial lt div gt function fact n console log factorial called if n lt return return n fact n Every time you change the value of the number factorial called is logged to console That s expected However if we Re render without changing the number factorial called isn t logged to console because useMemo gt fact number number returns the memoized factorial calculation And hence saving us from calling the function again and recalculating useMemo is a Hook so you can only call it at the top level of your component or your own Hooks You can t call it inside loops or conditions I hope now you understand how useMemo works in React Thanks for reading	2023-07-19 12:39:10
海外TECH	DEV Community	Running Slack App on Cloudflare Workers	https://dev.to/seratch/running-slack-app-on-cloudflare-workers-3hhn	Running Slack App on Cloudflare WorkersRecently as a weekend hobby project I created a Slack app development framework for Cloudflare Workers and Vercel Edge Functions In this article I will explain the basics of Slack app development and how to use the following libraries If you are already familiar with Slack app development and want to try it out right away it might be faster to read the documentation by following the links from the README Slack App development basicsLet me explain a little about the basics of Slack app A Slack app is a mechanism for adding features such as bots that can converse in a Slack workspace workflows that respond to events that occur within Slack e g someone joining a channel slash commands shortcuts etc There are two ways to communicate between this Slack app and Slack s API server Request URL Set up a public endpoint in advance on the app configuration page at receive event data from Slack and respond with HTTP responses or Web API calls Socket Mode Receive event data from Slack via a WebSocket connection and respond with WebSocket messages or Web API calls The latter Socket Mode is useful for local development or when it is not possible to expose a public URL In this article I will guide you on how to develop a Slack app by setting the URL issued when deployed to Cloudflare Workers as the Request URL Digression New platform feature for Workflow BuilderBy the way since the beginning of this year a new app development mechanism for extending the Workflow Builder called the next generation automation platform has been added to the Slack platform In the Workflow Builder there is one starting point called a trigger and small processes called steps are connected in series to form a workflow The next generation platform allows you to create your own steps While it has become easier to automate within Slack there are things that cannot be done with existing app development For example as of you cannot add slash commands to the entire workspace or set a home tab for users Also note that this next generation platform feature is only available in paid Slack workspaces and usage charges apply for workflow executions that exceed the free tier For more details please read the series of articles I wrote a few months ago Wanna go without any libraries You might think if all I need to do with Cloudflare Workers fetch function is receiving request data at most calling Slack s Web API or other services and returning an HTTP response why not just implement it without bothering to use a library Of course you could implement all the things all yourself However considering the following points it s hard to deny that implementing everything yourself every time can be quite a hassle Request verificationThe Request URL of a Slack app is a URL that is publicly available on the internet and the source IP address of Slack s requests is not always guaranteed to be the same Therefore there is a risk that a malicious third party could mimic the payload sent from Slack and make requests As a countermeasure against this every HTTP request from Slack includes headers called x slack signature and x slack request timestamp It is recommended that the Slack app side verifies the x slack signature string using the Signing Secret shared only with Slack and also checks that the x slack request timestamp is not an old date and time For more details please read the official documentation To implement this as code that runs on Cloudflare Workers you first need to read the request body as plain text and then implement the specified verification logic Here is an example of such an implementation export default async fetch request Request env Env ctx ExecutionContext Promise lt Response gt Request text on Cloudflare Workers prints warning const blobRequestBody await request blob const rawBody string await blobRequestBody text if await verifySlackRequest env SLACK SIGNING SECRET request headers rawBody Valid request pattern else Invalid signature or timestamp return new Response invalid signature status async function verifySlackRequest signingSecret string requsetHeaders Headers requestBody string const timestampHeader requsetHeaders get x slack request timestamp if timestampHeader return false const fiveMinutesAgoSeconds Math floor Date now if Number parseInt timestampHeader lt fiveMinutesAgoSeconds return false const signatureHeader requsetHeaders get x slack signature if signatureHeader return false const textEncoder new TextEncoder return await crypto subtle verify HMAC await crypto subtle importKey raw textEncoder encode signingSecret name HMAC hash SHA false verify fromHexStringToBytes signatureHeader substring textEncoder encode v timestampHeader requestBody function fromHexStringToBytes hexString string const bytes new UintArray hexString length for let idx idx lt hexString length idx bytes idx parseInt hexString substring idx idx return bytes buffer Various formats of payloadsDue to historical reasons the format of the request body sent from Slack varies depending on the feature For the Events API it s Content Type application json but for other features it s application x www form urlencoded and the format of the contents differs between slash commands and other features To accommodate all patterns you need to implement something like this Various data patternsSlack s developer platform supports a wide variety of events And for each event there are quite a few edge cases and diverse data patterns when you delve into the details For example even channel messages which are the most basic data can be just text or can include rich text and interactive components using blocks from Block Kit When files emails etc are attached they are also added as attachments Also this is a point for improvement in Slack s developer support but there is a lack of comprehensive documentation on payloads So sorry For this reason using a library like the one I developed this time and receiving support from TypeScript types this area can be much easier Why don t you use Bolt Many of you may be aware of Bolt for JavaScript an npm package that serves as a framework for developing Slack apps It s an official full stack Slack app development framework developed by the Slack Developer Relations team of which I am a member to free Slack app developers from the hassles I mentioned above However unfortunately Bolt for JS depends on axios and other Node js APIs and cannot be used directly with Cloudflare Workers Although its name is for JavaScript it s more of a framework for Node js Also while Bolt for JS is designed to be extended with an interface called Receiver this aspect does not mesh well with the specification of processing requests as Cloudflare Workers fetch function This also becomes a constraint when you want to run it as part of a web application using modern frameworks like Next js or Nest js Since I often get questions about this I explored possible ways on the weekends and eventually created a library to circumvent the constraints of the Receiver At the moment there are no plans to transfer this Bolt HTTP Runner into the st party SDKs However I intend to continue maintaining it as much as I can as an individual so if you really want to try running it on Next js or something similar please use or fork this library I digressed a bit As you can see it s surprisingly difficult or was to properly create a Slack app on Cloudflare Workers For example this app that implements integration with ChatGPT is doing all the things I mentioned above on its own When I was playing with Cloudflare Workers on the weekend I thought I want to make it easier to create Slack apps and found the time to create the slack cloudflare workers and slack edge libraries Initially I put all the implementation into slack cloudflare workers but along the way I realized that most of it could also be used with Vercel Edge Functions and presumably other similar runtimes so I extracted that part as slack edge and left only the OAuth flow related implementation such as managing installation information using KV in slack cloudflare workers And while this library was originally a hobby project aimed solely at running on edge functions as I progressed with the implementation I was able to complete it as something that solved the challenges that Bolt for JS had been facing for a long time Streamlined Slack Web API clientImproved portability Eliminated all dependencies on axios and other rd party modules as well as Node js implemented to depend only on the Fetch APIImplemented more precise TypeScript typing for API response data especially the types of Block Kit components are much easier to use Support for Web APIs that are only available on the Next Generation PlatformSimplified code by completely removing support for deprecated APIsNative support for async code execution to avoid second timeoutsEquipped with a feature equivalent to Bolt for Python s Lazy Listeners as standard using the Fetch event s waitUntil commandResolved issues with TypeScript support in Bolt for JSChanged the behavior and payload type of app message listener to be more intuitiveBy removing support for deprecated features such as old style dialogs and button click events in attachments the type of app action listener arguments is more clearly definedDesigned to enable developers to more easily avoid the error saying you ve called ack method several times when matching multiple listenersMore strictly defined the types of returned values from listenersAdded features missing in Bolt for JSAdded middleware mechanism that runs before the authorize functionAdded support for Sign in with Slack OpenID Connect featureAdded Socket Mode for local development without other dependency libraries this is still experimental Added supports for emerging JavaScript TypeScript runtimes such as Deno and BunFor those who are not familiar with Slack app development it may seem like a lot of things that aren t quite understandable but the point is It s not just that it works on Cloudflare Workers it s also improved in many ways over Bolt for JS If you re going to create a Slack app with TypeScript in I think it s not an exaggeration to say that this is the easiest library to use As I mentioned earlier it s designed to work with Deno and Bun as well so you can use it even if you want to run your Deno Bun app on a container service e g ks Amazon ECS not just on edge functions Ideally I d like to incorporate the insights gained from this development into Bolt for JS but most of them would result in breaking changes and as the DevRel team most of the members are focusing on the next generation platform so the improvements I could add to the st party ones are still very limited I hope to be able to do it little by little Getting StaredThe introduction might be quite long Now let s finally create a Slack app Most of the things are already written in the library s README but I ll go over them with more

can be sent as an ephemeral message return What s up lazy function can do whatever you want to do asynchronously async req gt await req context respond text Hey This is an async response return await app run request ctx If everything is working correctly you should not get an error this time and you should see two ephemeral messages displayed You might be wondering Why are we passing two functions to app command here This mechanism of executing two functions ack lazy was originally something I devised for Function as a Service environments like AWS Lambda Slack s event delivery requires rd party apps to respond within seconds but in AWS Lambda once a function triggered by an HTTP request returns an HTTP response the runtime can be terminated so you can t perform time consuming asynchronous processing after returning a response As a solution for it Bolt for Python s Lazy Listeners were designed to handle asynchronous processing in a separate AWS Lambda execution with the same input However with Cloudflare Workers there is already a mechanism called the Fetch event s waitUntil command so there s no need for such a workaround and the same thing can be achieved with a simple implementation THIS IS AMAZING By the way when it s clear that the lazy processing is not needed you can omit the second function However if you go with this implementation make sure that all processing finishes within seconds If that s always true move the time consuming processing to the second asynchronous execution function app command hey cf workers async gt return What s up Slash commands and Block Kit interationsLet s improve the above slash command example further by adding a message with a Block Kit button and also add a process for when the button is pressed Post a message

code overwrites the original message where the button was placed If you set the response type to in channel you can post it as a message that can be seen by other people in the channel The context respond is a utility that uses response url to send a message There is also an example of opening a modal that just conveys the same text in the else clause of the above code so please try that as well if you like Shortcuts and modal data submissionsNext I will introduce an example where a modal opens when a global shortcut is executed and input validation is performed when data is sent An

context userId gt is there anything I can help you with If you want to create an app that responds to other events you can specify the events from this list in the app configuration pages and reinstall it in the workspace to be able to receive them The payload argument of the listener function is resolved to the data type of the specified event payload If there are any deficiencies or errors please report them to this issue tracker and I will correct them I appreciate your help Deploy to CloudflareThat s it for the implementation of the features Now let s deploy this app to the Cloudflare Workers environment and see it in action wrangler deployIf the deployment is successful the console will output something like this wrangler deploy ️wrangler Total Upload KiB gzip KiBUploaded my slack app sec Published my slack app sec Current Deployment ID fde edde b bc acdbfcdbdIf you want to switch the app you just tested locally to production as is it s a bit of a hassle

create a production app with a new separate configuration it would be easier to replace the part of the App Manifest YAML configuration file with the issued production URL and then create the app As the last step tell the Signing Secret and Bot User OAuth Token set in dev vars to the production secrets For this step as well if you are creating a new production app separately the values will be different so please obtain them from the Slack app management screen after installing them in your workspace and specify those values wrangler secret put SLACK SIGNING SECRETwrangler secret put SLACK BOT TOKENThe console outputs will look like this wrangler secret put SLACK SIGNING SECRET ️wrangler Enter a secret value … Creating the secret for the Worker my slack app Success Uploaded secret SLACK SIGNING SECRET wrangler secret put SLACK BOT TOKEN ️wrangler Enter a secret value … Creating the secret for the Worker my slack app Success Uploaded secret SLACK BOT TOKENOnce all the settings are complete please check to see if it works the same way when switched Perhaps the app running in the production environment can respond much more quickly More advanced topicsLet me briefly touch on some more advanced topics I may publish more blog posts for these topics in the near future Enable the OAuth flowThe steps above are for creating the simplest type of app one that only operates in a single workspace This article has gotten a bit long so I ll explain the details in another article but if you want the same app to work in other workspaces you can provide your own OAuth flow for installation so far we ve been installing using the installation flow provided by the Slack app management screen right This is about switching to your own and by properly managing the installation information for multiple workspaces you can distribute your app to other workspaces Also by implementing the OAuth flow you can not only get bot permissions like this article does but also receive permissions to view or operate some information from each user in the workspace allowing you to change statuses post messages access search results etc on behalf of the user if you install from the management screen without implementing the OAuth flow you can only issue your own user token The slack cloudflare workers library already provides a feature to implement Slack s OAuth flow using Cloudflare s KV For more details please refer to this document and the code examples Sign in with SlackThe library also supports the feature of logging into external sites with a Slack account compatible with OpenID Connect There is currently no documentation for this feature so I plan to first enhance the documentation and then introduce how to implement it in some form Run your app outside of edge functionsI mentioned this briefly in the middle of this article but this slack edge library is also compatible with Deno and Bun Also as of the time of this article s posting it s still in the experimental stage but it does support socket mode to some extent If you like this library and want to use it not only for edge functions but also for developing apps that run on container services running it on Deno Bun might be a good idea There are some sample codes here so please refer to them Wrap up Will anyone read this to the end This article has become quite long Thank you so much for reading this far Cloudflare Workers are truly convenient Especially the Fetch event s waitUntil command is absolutely fantastic I almost thought it was a feature designed specifically for Slack apps joking Also the development experience is very smooth and I think it can be used for various purposes not limited to Slack apps As for slack edge and slack cloudflare workers they are completely my personal hobby projects So I m not sure how much time I can devote to them but I hope to continue improving them at my own pace Currently they only support KV so I want

海外TECH	DEV Community	What is Event Bubbling? event bubbling in JS	https://dev.to/diwakarkashyap/what-is-event-bubbling-event-bubbling-in-js-4kn7	What is Event Bubbling event bubbling in JSEvent bubbling in JavaScript refers to the way events are handled and propagated through the different elements of a webpage When an event occurs on an element such as a button click the event doesn t just trigger on that specific element Instead it also triggers on its parent elements all the way up to the topmost element usually the document Imagine a scenario where you have a button inside a div and that div is inside another div If you click the button the click event will not only be detected by the button itself but also by its parent div and the outer div This bubbling behavior allows you to capture events at different levels of the DOM hierarchy For example you can have a single event listener attached to the outer div and it will be triggered for events that occur on the button the inner div or the outer div itself Event bubbling can be useful because it simplifies event handling Instead of attaching event listeners to each individual element you can attach a single listener to a parent element and let the event bubble up to it This reduces the amount of code you need to write and makes it easier to manage events However in some cases you may want to stop the event from bubbling further up the DOM hierarchy You can use the event stopPropagation method inside an event handler to prevent the event from triggering on parent elements This can be handy when you want to isolate the event handling to a specific element and prevent any further handling by its ancestors In summary event bubbling in JavaScript refers to the propagation of events from a child element to its parent elements It simplifies event handling by allowing you to capture events at higher levels in the DOM hierarchy Thank you for reading this blog follow me on Twitter I regularly share blogs and post on Javascript React Web development and opensource contributionTwitter Github	2023-07-19 12:02:48
