Awesome TypeScript Compilers, Transpilers and Runtimes

A curated list of TypeScript compilers, transpilers and runtimes targeting various languages and platforms.

Type checking vs. transpilation: Running or transpiling TypeScript does not necessarily check types. For example, esbuild and Node.js type stripping do not perform type checking; use a separate checker such as tsc --noEmit.
