  • JS Toolbox 2024: Bundlers and Test Frameworks
    10 projects | dev.to | 3 Mar 2024
    Jest, created and maintained by Facebook, is a JavaScript testing framework with a focus on simplicity. It is often recognized for its zero-configuration setup and seamless integration, especially with React applications, making it a favored choice for developers in both small-scale projects and large enterprise applications.
  • Unit Testing Expo Apps With Jest
    7 projects | dev.to | 20 Feb 2024
    console.error Jest encountered an unexpected token Jest failed to parse a file. This happens e.g. when your code or its dependencies use non-standard JavaScript syntax, or when Jest is not configured to support such syntax. Out of the box Jest supports Babel, which will be used to transform your files into valid JS based on your Babel configuration. By default "node\_modules" folder is ignored by transformers. Here's what you can do: • If you are trying to use ECMAScript Modules, see https://jestjs.io/docs/ecmascript-modules for how to enable it. • If you are trying to use TypeScript, see https://jestjs.io/docs/getting-started#using-typescript • To have some of your "node\_modules" files transformed, you can specify a custom "transformIgnorePatterns" in your config. • If you need a custom transformation specify a "transform" option in your config. • If you simply want to mock your non-JS modules (e.g. binary assets) you can stub them out with the "moduleNameMapper" config option. You'll find more details and examples of these config options in the docs: https://jestjs.io/docs/configuration For information about custom transformations, see: https://jestjs.io/docs/code-transformation

    On top of that, Vite’s compiler is super fast, supports Typescript (which we of course used), and built just fine on our host, which was Cloudflare Pages. Cloudflare Pages is a super fast static website hosting service by Cloudflare, which allows your site to take advantage of their global CDN to make sure your site is as close to your users as possible. It supports nearly any JS framework you could want to use for your site, and can even host plan old HTML if you’re of that persuasion.

  • Six Factors That Raise The Risk Of Bugs In A Codebase
    2 projects | dev.to | 4 Mar 2024
    1. Lack of Static Code Analysis Static code analysis tools like TypeScript and ESLint play a crucial role in identifying and preventing bugs. TypeScript provides static typing, enhancing the robustness of the code. ESLint detects issues and enforces coding standards. The absence of these tools can significantly elevate the likelihood of bugs due to the lack of early detection and guidance provided during development.

    In recent years, TypeScript has become an indispensable tool for many JavaScript developers, offering type safety, improved code maintainability, and enhanced developer experience with many advanced type features, like generic types, type guards and conditional types. One of the powerful features introduced in TypeScript 4.1 is template literal types which provide greater flexibility and control over string literal types.
  • BiomeJS 2024 Roadmap
    5 projects | news.ycombinator.com | 22 Jan 2024
    Calling the TypeScript Compiler could slow down our linter making the switch from TypeScript ESlint to Biome less attractive. We don't aim to build a complete type system, just the minimal parts to be able to implement most the linter rules that requires type info. The idea is to build on the upcoming TypeScript Isolated Declarations [0]. If this is too much of work, then we will review our options.
