  • puppeteer

    Headless Chrome Node.js API

    Project mention: Web Scraping With Puppeteer for Total Noobs | dev.to | 2023-01-30

    Web scraping is something I never thought I'd do. I'm primarily a UI developer, although my career started as a backend developer. I've never been asked at a job to perform any scraping tasks, and I'd never had a personal project that required me to scrape some data until recently. I'll share what I've learned, which is honestly probably just scratching the surface of what you can do with a technology like Puppeteer. In this post I'll walk you through installing and writing a Node.js script that will scrape a weather forecast website. The weather forecast site isn't my personal project that I mentioned earlier, it's more of a contrived example of how to get started with web scraping using Node.js and Puppeteer.

    Project mention: Starchart: Playwright and Chakra UI Setup | dev.to | 2023-02-03

    The past week I worked on setting up Playwright, and Chakra UI with starchart. Chakra UI is needed so that their components could be used to build the web pages, and Playwright is to be used for end-to-end testing.

    Project mention: Do you use Storybook in your React Native projects? | reddit.com/r/reactnative | 2022-03-31

    I switched to cosmos (https://github.com/react-cosmos/react-cosmos ) awhile back and like it a lot more. Storybook might have caught up this now I havnt tried again since.

    A Jest transformer with source map support that lets you use Jest to test projects written in TypeScript.

    Project mention: Is using Jest for anything other than React a bad idea? | reddit.com/r/node | 2022-09-12

    ts-jest has had some strange performance issues and workarounds in the past, though I haven’t used it very recently so it might have fixed those by now.

    Project mention: Domain Layer and React? Decorators to the Rescue! | dev.to | 2023-01-13

    Of course, you could isolate the logic inside a hook, and there's an awesome way of testing it with renderHook. But yet, you're trapped into react features, if they change their API, you will have to put your hands in your working logic and adapt some stuffs to keep up to date.

  • Cucumber.js

  • fast-check

  • react-native-testing-library

    🦉 Simple and complete React Native testing utilities that encourage good testing practices.

    Project mention: Performance Regression Testing for React Native | dev.to | 2023-01-27

    Introducing a new tool means introducing a new workflow. This can lead to lower adoption, as developers need to to get familiar with it in the first place. To prevent that from happening, we've based Reassure on https://callstack.github.io/react-native-testing-library/ API as something React Native developers should be familiar with.

  • testing-nestjs

    Spinning up mongod in memory for fast tests. If you run tests in parallel this lib helps to spin up dedicated mongodb servers for every test file in MacOS, *nix, Windows or CI environments (in most cases with zero-config).

    Project mention: How to test nestjs modules? | reddit.com/r/Nestjs_framework | 2022-10-13

    In the case of MongoDB there's jest-mongodb that use mongodb-memory-server; for other DBMS, I don't know if it's possible to run an instance in memory.

    Project mention: A guide to visual debugging with Vitest Preview | dev.to | 2023-01-26

  • generatedata

    A powerful, feature-rich, random test data generator.

    Project mention: Optimizing massive MongoDB inserts, load 50 million records faster by 33%! | dev.to | 2022-10-16

    To play around with data generation and make a custom dataset I can recommend using — https://generatedata.com/. I’ve used it to generate 1🍋 records of the data. At the moment of writing this article, the basic yearly plan costs 25$ and you would not regret it.

  • ladle

    🥄 Develop, test and document your React story components faster.

    Project mention: Component development with ladle and next/image | dev.to | 2023-01-30

    After another look at issue #100, we can tell next/image that it should skip the optimization if the component is rendered in Ladle. That is fine, because the bandwidth does not play a big role during the development. With the following code placed inside .ladle/components.tsx ...

  • user-event

    🐕 Simulate user events

    Project mention: How do I test a button that change a state with jest ? | reddit.com/r/reactjs | 2022-12-14

    You probably want to be using user-event instead of fireEvent.
