esbuild-jest-transform

A Jest transformer that uses esbuild for fast code transformation, supporting JavaScript, TypeScript, and JSX. Current stable version is 2.0.1. It allows passing custom esbuild transform options via Jest config, such as target, loaders, and format. Compared to alternatives like ts-jest or @swc/jest, it leverages esbuild's speed but offers less plugin ecosystem. Updated as of 2023, with peer dependency on esbuild >=0.17.4 <1.0.0.
