library0.8.0jsnpmunverified

Transpile TypeScript to ESM using Node.js loader hooks, leveraging esbuild for fast compilation. Current stable version is 0.8.0. Release cadence is irregular, with updates addressing loader hook deprecations and minor features. Compared to esbuild-register, this package targets Node.js ESM (ECMAScript Modules) rather than CommonJS. It supports .ts, .tsx, and .json files, and resolves extensions automatically. Primarily used as a development tool for running TypeScript files directly with Node.js without a separate build step.
