海外TECH	DEV Community	The JUICE of Reactive Programming in Angular	https://dev.to/handsometunex123/the-juice-of-reactive-programming-in-angular-3mel	The JUICE of Reactive Programming in AngularReactive programming in angular in the most basic form is the adoption of RxJS Reactive Extensions for JavaScript to angular application development RxJS is a powerful library adopted in Angular that makes asynchronous operations super easy This article focuses on revealing to you the juice of reactive programming by providing you a reactive approach to solving one of the most common real world problems encounted by angular developers Enough of the long talks lets get our hands dirty Imagine you were assigned a task to create a users table mat table that is populated mainly by making an asynchronous call to an endpoint that returns a list of users The table should Have on it server side pagination The parameters provided by the API in this case for pagination include a pageSize and a pageIndex For example appending a pageSize of and a pageIndex of to the URL as query string means users will be spooled for the first page The URL suffix should look something like this users pageSize amp pageIndex A search parameter to filter the entire records of users based on specified search input typed in by the user For this an input field is to be provided on top of the table to allow users type in their search query e g typing in brosAY should bring in all the users related to brosAY The URL suffix should look something like this users pageSize amp pageIndex amp searchString brosAYHave a loader that shows anytime we are making an API call to retrieve new set of users Mostly when the previous or back button is pressed Now lets implement this reactively The first thing to do is to introduce the angular mat table How to implement angular mat tableand a formControl on top of the table On the template we have SEARCH FORM CONTROL lt mat form field appearance fill gt lt mat label gt Input your search text lt mat label gt lt input matInput placeholder Search formControl searchInput gt lt button mat icon button matPrefix gt lt mat icon gt search lt mat icon gt lt button gt lt mat form field gt USERS TABLE lt div class mat elevation z gt lt table mat table dataSource dataSource gt lt ng container matColumnDef id gt lt th mat header cell matHeaderCellDef gt User ID lt th gt lt

container gt lt ng container matColumnDef address gt lt th mat header cell matHeaderCellDef gt Address lt th gt lt td mat cell matCellDef let user gt user address lt td gt lt ng container gt lt tr mat header row matHeaderRowDef displayedColumns gt lt tr gt lt tr mat row matRowDef let row columns displayedColumns gt lt tr gt lt table gt lt Mat Paginator gt lt mat paginator page onPageChange event length dataLength pageSizeOptions showFirstLastButtons gt lt mat paginator gt lt div gt In the ts displayedColumns string id name age address Form Control for search inputs on the tablesearchInput new FormControl lt User gt represents the User Model dataSource new MatTableDataSource lt User gt Inject the UserServiceconstructor public userService UserService Mat paginator by default has a page event that we will be leveraging to handle our pagination the page output event on the paginator emits all that we need to handle our pagination I will extract mainly the tail end of the HTML code on the template to explain this part in the html we have lt Mat Paginator gt lt mat paginator page onPageChange event length dataLength pageSizeOptions showFirstLastButtons gt lt mat paginator gt lt div gt in the ts we have constructor public userService UserService we initialize the pageIndex to and pageSize to pageIndex number pageSize number this method receives the PageEvent and updates the pagination Subject onPageChange event PageEvent void gt the current page Index is passed to the pageIndex variable this pageIndex event pageIndex the current page Size is passed to the pageSize variable this pageSize event pageSize the pagination method within the user service is called and the current pagination passed to it this userService updatePagination pageIndex this pageIndex pageSize this pageSize Because Angular makes use of typescript as its core we will be creating a model for our pagination So we create a pagination models ts file that will contain our pagination model export interface Pagination pageIndex number pageSize number We proceed to introduce a subject behaviorSubject that will be constantly updated anytime the pagination requirement changes For this scenario a behaviorSubject is prefered because we need a default state for our pagination which is a pageSize of and a pageIndex of With this in place the first time the page is accessed users is always retrieved on the first page by default This is in contrary to subjects that do not allow a default state However applying a startwith rxjs operator on a subject and setting a value can also make it behave just like a behaviorSubject lt Pagination gt stands as the BehaviorSubject s model which means that any value that will be assigned to the behaviorSubject must conform to the Pagination model within the is where we specify the default value for our pagination which is pageSize of and pageIndex of in this case private paginationSubject new BehaviorSubject lt Pagination gt pageIndex pageSize Provision another subject behaviorSubject that will be constantly updated anytime a search input has been typed in lt string gt below as usual stands for the data type of the value that is allowed to be passed into the subject private searchStringSubject new BehaviorSubject lt string gt null On the side To avoid immediate calls to our API when the user starts typing into the form control to initiate a search we apply a pipe on the valueChanges of the searchInput formControl in order to access the debounceTime one of RxJS operators that will help delay passing down the string for API calls until a specified time in ms is provided e g debounceTime delays call to the API for s before the string is passed down for API call read more on DebounceTime As we have here Form Control for search inputs on the tablesearchInput new FormControl constructor public userService UserService ngOnInit this trackSearchInput method triggers when the search Form Control value changes the changed value doesnt get passed on until after strackSearchInput void gt this searchInput valueChanges pipe debounceTime subscribe searchWord string gt this userService updateSearchStringSubject searchWord For best practices we implement the concept of encapsulation one of OOP concepts Notice that a private access modifier was applied on the Behavior Subject meaning that we are restricting the update of the BehaviorSubject only within the service However to still ensure we get the B Subject updated from anywhere within our app we expose a method that can be called anytime an update needs to be done on the BehaviorSubject this method is the only single point where the pagination subject can be updated updatePaginationSubject pagination Pagination void gt this paginationSubject next pagination Likewise this method is the only single point where the search string subject can be updated updateSearchStringSubject searchString string void gt this searchStringSubject next searchString Now that we have a method that can be called from any part of our app to set our subjects we proceed to expose their values by converting them to observables and also applying a public access modifier on the observables so they be accessed easily from any part of our app Converting Subjects to observables can be achieved by calling the asObservable on them For the pagination BehaviorSubject we have private paginationSubject new BehaviorSubject lt Pagination gt pageSize pageIndex below convert the pagination BehaviorSubject to an observable public pagination this paginationSubject asObservable For the search string subject we have private searchStringSubject new BehaviorSubject lt string gt null searchString this searchStringSubject asObservable Now that we have a pagination observable pagination to handle change in paginations and another observable searchString to handle change in search input We move on to combine the two observables using an RxJS operator combineLatest We are combining them because we need the latest values from them at every point in time to do our API call to get a new set of users For combineLatest all the observables to be combined must have emited atleast once before it emits a value In cases where you are using a Subject for the search string you have to adopt the startWith rxjs operator on the search string observable to automatically make the subject behave like a behavior subject Assuming we were using a Subject for Search String we have thispaginatedUsers combineLatest this pagination this searchString pipe startWith null starts with an empty string However because we already have a default state of null for the search string we have this paginatedUsers combineLatest this pagination this searchString Now that we have successfully combined the streams one more thing needed is an higher order mapping operator like an rxjs switchMap operator that will help handle subscription and unsubscription from inner observables out of the box In cases where the user initiates an action like clicking the previous button then immediately going on to click the next button the switchMap RxJS operator IMMEDIATELY helps to cancel the initial request triggered by clicking previous button and IMMEDIATELY moves on to subscribe to the response from the new request triggered on click of the next pagination button This process is handled graciously by the switchMap operator Other operators includes a mergeMap which on the other hand would sucbscribe to both calls irrespective of how fast the buttons are clicked in the user service ts we have baseUrl paginatedUsers Observable lt PagedUsers gt combineLatest this pagination this searchString pipe pagination stands for the pagination object updated on page change searchString stands for the search input switchMap pagination searchString gt this http get lt ApiResponse lt PagedUsers gt gt this baseUrl users pageSize pagination pageSize amp pageIndex pagination pageIndex amp searchInput searchString pipe map response gt response Result pipe shareReplay shareReplay is applied in this case because I want the most recent response cached and replayed among all subscribers that subscribes to the paginatedUsers within the shareReplay stands for the bufferSize which is the number of instance of the cached data I want replayed across subscribers The response e g paginatedUsers is then subscribed to with the help of an async pipe on the template async pipe helps you to subscribe and unsubscribe to observables automatically It basically saves you from the stress of writing long lines of code to handle unsubscriptions In our users component ts constructor public userService UserService the pagedUsers below is subscribed to on the template via async pipepagedUsers this userService paginatedUsers pipe tap res gt update the dataSource with the list of allusers this dataSource data res allUsers updates the entire length of

component that renders only when the loader observable has a value of true The above methods are also repeated for the loader Create the Loader ComponentCreate the Loader B Subject in the user service

on the template in such a way that the loader shows only when the loader observavle is true As soon as the previous next button is clicked or value is entered for the pagination the onPageChange method is triggered before calling the updatePaginationSubject we call the method that sets the loader B Subject to true Then as soon as response is returned from the API call to get users we set the loader subject back to false in the user component ts we initialize the pageIndex to and pageSize to pageIndex number pageSize number onPageChange event PageEvent void gt set the loader to true

海外TECH	DEV Community	How we use End To End tests to bulletproof our authentication flows across browsers	https://dev.to/clerk/how-we-use-end-to-end-tests-to-bulletproof-our-authentication-flows-across-browsers-4ib6	How we use End To End tests to bulletproof our authentication flows across browsersIn recent years End To End testing has become a regular topic of discussion in small team environments The main reasons for this are the evolution of tooling and the need to shift towards high velocity product development At Clerk we use End To End testing to create bulletproof authentication flows across browsers The ft view of the End To End landscapeIn the past End To End testing was almost exclusively considered a Quality Assurance Engineering topic For one reason or another the development of test automation pipelines and application workflow validation tests were not so popular with software engineers That view has gradually become dated and replaced with the growing popularity of tools like Cypress Puppeteer Playwright and even the latest version of Selenium The growth of those tools should not be seen as a simple technical advancement but instead as an immediate answer to the growing need to efficiently and effectively validate fast moving development cycles of agile teams At Clerk we deploy multiple times per day and without these tools it would be impossible to ensure reliability The high bar for reliability at ClerkAs a solution for authentication and user management Clerk must maintain exceptionally high reliability even as our product and team expands rapidly around our core offering It is critical that end users can always access their accounts quickly even through edge cases like originally signing up with Google then trying to sign in with email instead We also take great pride in our developer experience and often jump through hoops to ensure that Clerk works consistently across development staging and production environments and across all browsers To keep reliability high across our myriad of flows and importantly to give our own development team confidence that our product won t break with new deploys it became clear the most pragmatic solution was to develop an End To End test suite Laying out our needsThese were our initial needs exactly as voiced by our team Cross browserThe suite needs to cover all major browsers with as little external service interaction as possible Happy to code in Meaning TypeScriptMost probably Frontend Engineers should be able to write and maintain the tests for the suite with as much joy as possible Support containerized deploymentThe suite needs to be portable enough to run on a GitHub Action workflow Choosing a platformAfter investigating Selenium Puppeteer WebDriverIO Cypress and Playwright and weighing each platform against our needs we decided to go with Playwright Although it felt less hyped as a team we felt really confident in the architecture behind Playwright its stellar documentation and tooling and the excellent community backing the effort We will describe our exact selection process in a later post but most critically we appreciate the ability to execute our workflows across Chromium WebKit and Firefox with so much ease and fine grained control How the suite is orchestratedOur End to End test suite is a separate system from our main codebase as we have seen this pattern working really well for most applications Its main components as a Node js application written in TypeScript are Playwright as the browser automation framework Jest as the test suite runner jest playwright to connect Jest and Playwright as it makes our lives so much easier Faker js to create API fixtures that fit our needs for the sign up and sign in processes fixtures Page Objects as the main pattern representing the interaction facade with our application views in code These components have proved to work together seamlessly while staying welcoming to our frontend engineering team One of our main goals was to ensure that new teammates could understand the system quickly and create new tests and so far this structure has exceeded our expectations Delivery of the suite on our day to day effortsTo keep us safe from accidental regressions the test suite must run and pass before any merge to production To automate this process integration with our Continuous Integration CI tooling was essential We run our CI through Github Actions and fortunately the Playwright team has created GitHub Action tools to simplify triggering the test suite Paired with Vercel preview deployments which is where most of our CI tasks take place both Actions fit the spot quite nicely for End to End suite scenarios The Playwright team has also created a GitHub action to quickly bootstrap Playwright tests The final action file that triggers our End to End suite on every pull request looks something like this jobs ee if github event deployment status state success name End to End runs on ubuntu latest strategy matrix node version x steps uses actions checkout v uses microsoft playwright github action fbfdacddabdafdda uses actions setup node v with node version matrix node version name Run Playwright tests run cd ee amp amp npm install amp amp npm run testIf the action succeeds we are good to go Parting wordsThis was a really brief overview of how we went about designing our End to End test suite at Clerk As Clerk and our customers needs continue to evolve we will continue to share our experiences with Playwright and any new tools we adopt P S We have open sourced a template for starting up your own End To End suite using Playwright so feel free to try it out

海外TECH	DEV Community	Introducing Code House - A whole new world of 300+ Developer Cheatsheets 👨‍💻	https://dev.to/saviomartin/introducing-code-house-a-whole-new-world-of-300-developer-cheatsheets-m27	Introducing Code House A whole new world of Developer Cheatsheets ‍ Hello Folks This is Savio here I hope you all are doing good I m young web dev with an intention to enhance as a successful web developer Today I m super proud to introduce my latest and biggest ever project which I had made till date as a submission for HarperDB Hackathon on Hashnode Once the hackathon was announced I was super busy organizing my time and put myself into a good schedule to complete the project by the deadline After the hard work for days I finally could meet up with the project I had in my mind It was hard but I loved every moment of it Little flashbackDevelopers love cheatsheets we cannot leave without them Indeed that s true for me too I always spend a lot of time hunting for the best cheatsheets I waste a lot of time to find a good cheat sheet for my need That gave me the thought that what if I could build a super huge storehouse of developer cheatsheets and a user can get access easily to tons of cheatsheets according to his need Once I started building ️ I found that they re more I could do to improve it And that s how Code House started The project is never finished it is still becoming better and better I m glad I was able to create a super useful app for the DEV community ‍ Introducing Code HouseCode House is the all in one storehouse for developer cheatsheets Welcoming you to a whole new world of developer cheatsheets Code House is made up of curated cheatsheets from sources Filter by categories or source sort by time or popularity dark mode bookmark cheatsheets add new cheatsheets request feature and much more features make the app amazing Github Repo Live Demo ️InspirationHunting for cheatsheets took a lot of time and we developers don t like to waste it And that is how I came up with an idea to create a website that contains a huge amount of curated cheatsheets from the internet All cheatsheets are reviewed and there will no such spam giving developers a lot of time to code than hunt There are categories currently so if a user need a cheatsheet of a particular language he can just sort it up There is a lot of content on the internet and it is not so easy to sort out which one is good this is where code house takes place All cheatsheets are curated and reviewed by users therefore helping you to have the best one This was my first goal in mind and soon as I started building I put myself into a schedule to improve the app with more advanced features TL DRPlease watch the short teaser mins use headphones Now let me introduce you to the amazing features code house have so far ️ CheatsheetsCode House is well sufficient with more than developer cheatsheets from sources All the cheatsheets are sorted into categories making it easy to select one You can filter all the cheatsheets by popular oldest newest or even use the search
