Release Notes

cacjs/cac (cac)

v7.0.0

Compare Source

🚨 Breaking Changes

• Drop Node.js < 20.19.0 support. Node.js 20.19.0 is now the minimum required version.
• Remove CJS build. CAC is now ESM-only. If you rely on require(), either migrate to ESM imports or upgrade to Node.js ≥ 20.19.0, which supports require() for ES modules natively.
• Rename event listener methods to follow the EventTarget API. cli.on() and related methods have been renamed to cli.addEventListener(). Update your code accordingly:

--- cli.on('command:*', () => { ... })
+++ cli.addEventListener('command:*', () => { ... })

Notes for Deno Users

Please use the JSR package instead: @cac/cac

import cac from 'jsr:@​cac/cac'
