jiti is a zero-dependency Node.js library and CLI that provides runtime TypeScript and ESM support with seamless ESM/CommonJS interoperability. It offers both asynchronous import and synchronous require APIs, filesystem transpile caching, and ESM loader support.

Use cases

• run typescript files directly with node
• import typescript modules at runtime
• replace require with esm-compatible loader
• load config files written in typescript
• run esm and commonjs modules interchangeably
• add typescript support to a node.js cli tool

When to choose

• you need to execute TypeScript or ESM files at runtime without a build step
• you're building a tool (like a config loader or CLI) that must load user code written in TypeScript
• you need ESM/CommonJS interoperability with require.cache integration and disk caching

When to avoid

• you only need standard Node.js type stripping in modern Node versions without extra features
• you need full bundling or type-checking rather than runtime transpilation
• your project targets browsers rather than Node.js
