svelte-jester
A Jest transformer that precompiles Svelte components for testing, supporting both ESM and CJS.
What is svelte-jester?
svelte-jester is a Jest transformer for Svelte applications. It compiles Svelte components into JavaScript modules that Jest can understand, enabling unit and integration testing for Svelte projects. It solves the problem of Jest being unable to directly import and test .svelte files by handling the necessary precompilation.
Developers using Jest as their test runner in Svelte projects, particularly those working with Svelte 4+ (ESM) or Svelte 3 (CJS), and those requiring preprocessor support for TypeScript, SCSS, or other compile-time transformations.
Developers choose svelte-jester for its active maintenance, reliable preprocessor support, and straightforward configuration, addressing gaps found in other libraries. It offers unique flexibility with ESM/CJS support, configurable compiler options, and root mode configuration for monorepos.
