storybook
📓 The UI component explorer. Develop, document, & test React, Vue, Angular, Web Components, Ember, Svelte & more!
import React, { FC, HTMLAttributes, ReactChild } from 'react'; import { Button, ButtonProps } from './Button/Button'; export interface Props extends HTMLAttributes { /** custom content, defaults to 'the snozzberries taste like snozzberries' */ children?: ReactChild; } // Please do not use types off of a default export module or else Storybook Docs will suffer. // see: https://github.com/storybookjs/storybook/issues/9556 /** * A custom Thing component. Neat! */ const Thing: FC = ({ children }) => { return
{children || `the snozzberries taste like snozzberries`}; }; export { Thing, Button, ButtonProps }; -
Scout APM
Scout APM - Leading-edge performance monitoring starting at $39/month. Scout APM uses tracing logic that ties bottlenecks to source code so you know the exact line of code causing performance issues and can get back to building a great product faster.

You cannot completely neglect one essential area of software development: automated testing. There are many different testing libraries or test runners available for JavaScript. However, today we'll learn about Jest, a testing library developed and used internally by Facebook, that resembles Mocha the previous king of JavaScript testing libraries.

As of Angular 12, Protractor won't be included by default in new projects. Instead, the Angular CLI will provide options to use other solutions like Cypress, WebdriverIO, or TestCafe. This means that the ng e2e command should continue to be supported in the future.
-
ts-jest
A Jest transformer with source map support that lets you use Jest to test projects written in TypeScript.
Project mention: Help me understand the state of TS mocking ecosystem | reddit.com/r/typescript | 2021-05-15My team uses ts-jest and for mocking complex objects factoree is really awesome.

garden
Automation for Kubernetes development and testing. Spin up production-like environments for development, testing, and CI on demand. Use the same configuration and workflows at every step of the process. Speed up your builds and test runs via shared result caching.
Project mention: You Don't Need to Rebuild Your Development Docker Image on Every Code Change | news.ycombinator.com | 2021-05-31Garden[0] is tool we built (yes, I'm affiliated :)) that has a lot of this functionality built-in. Might fit your use case.
We recently re-wrote the hot reload functionality to use Mutagen[1] under the hood and its insanely fast (<200ms anecdotally). It also does two way sync which can be useful. The old implementation used rsync but a lot of our Windows users struggled with that. So I figured I'd share in case that sounds familiar.
What happens after a sync event depends on the stack, but we've had pretty good success with Entr[3]. We often have it watch a single file so that multiple watchers in a shared dev cluster don't eat up all the node's resources.

Project mention: Attention! As of today, updating the VS Code Python extension automatically installs proprietary software on your computer! | reddit.com/r/linux | 2021-05-11
But I mean, this doesn't prevent you from writing an open source extension that runs regardless of which version a user chooses to use, right? Users who are using the open source version of VS Code aren't forced to install the proprietary version with PyLance. The old extension is open source and even had a release just 18 hours ago - https://github.com/Microsoft/vscode-python

Maybe another self-hosted service could cover hosting and be integrated with the generatedata script as the datasource. Let me know if you find something. I was just using Mockaroo this morning and considering a paid plan.
-
mongodb-memory-server
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: Show HN: Mongita is to MongoDB as SQLite is to SQL | news.ycombinator.com | 2021-04-20 -
https://github.com/ngneat/spectator is awesome and supports jest. (uses jasmine by default)
-
testing-nestjs
A repository to show off to the community methods of testing NestJS including Unit Tests, Integration Tests, E2E Tests, pipes, filters, interceptors, GraphQL, Mongo, TypeORM, and more!
Project mention: Anyone who would be willing to show their sample repos? | reddit.com/r/node | 2021-04-24 -
Project mention: What UI testing framework do you use and what do you like/dislike about it? | reddit.com/r/Angular2 | 2021-04-29
jest-codemods helped us a lot moving from Jasmine to Jest, removes most of the manual work

There's a very cool library called ts-mockito, it works very well when you use dependency injection in your code (as we're doing now). It allows you to create mocks, stub function calls, and many other cool features, definitely check it out! I'm going to use it to test our AuthRepository.
-
testcontainers-node
TestContainers is a NodeJS library that supports tests, providing lightweight, throwaway instances of common databases, Selenium web browsers, or anything else that can run in a Docker container.
Luckily, Testcontainers is a great project that makes setting up external resources more comfortable by providing a programmatic interface to run Docker containers in testing scenarios. In this article, we'll be looking at a community port of Testcontainers for Node.js (testcontainers-node), and how we can run tests that rely on both a single Redis and a Redis Cluster.
