esbuild-jest2
JSON →A Jest transformer that uses esbuild for fast compilation of TypeScript, JavaScript, JSX, and TSX files. Version 0.6.7 is the latest stable release, maintained as a fork of the abandoned esbuild-jest with active updates for Jest v29+. It integrates esbuild's blazing-fast bundler into the Jest transform pipeline, supporting custom loaders, sourcemaps, JSX factory/fragment configuration, and target/format options. Unlike ts-jest, which relies on tsc, esbuild-jest2 offers significantly faster transformation but does not enforce type checking. It requires esbuild >=0.20.1 as a peer dependency and ships TypeScript declarations.
