Installing the latest version

You can install the latest version by using:

  • npm install @headlessui/react@latest
  • npm install @headlessui/vue@latest

Installing the insiders version

You can install the insiders version (which points to whatever the latest commit on the main branch is) by using:

  • npm install @headlessui/react@insiders
  • npm install @headlessui/vue@insiders

Note: The insiders build doesn't follow semver and therefore doesn't guarantee that the APIs will be the same once they are released.
