Runtime Typescript and ESM support for Node.js.

[!IMPORTANT] This is the support branch for jiti v1. Check out jiti/main for the latest version and unjs/jiti#174 for the roadmap.

Features

• Seamless typescript and ESM syntax support
• Seamless interoperability between ESM and CommonJS
• Synchronous API to replace require
• Super slim and zero dependency
• Smart syntax detection to avoid extra transforms
• CommonJS cache integration
• Filesystem transpile hard cache
• V8 compile cache
• Custom resolve alias

Usage

Programmatic

const jiti = require("jiti")(__filename);

jiti("./path/to/file.ts");

You can also pass options as second argument:

const jiti = require("jiti")(__filename, { debug: true });

CLI

jiti index.ts
# or npx jiti index.ts

Register require hook
