The clerk-dev CLI is a tool designed to simplify the process of iterating on packages within the clerk/javascript repository within sample applications, such as customer reproductions. It allows for the installation of the monorepo versions of packages, and supports features such as hot module reloading for increased development velocity.

npm install --global @clerk/dev-cli

If you haven't already, install turbo globally.

npm install --global turbo

After installing @clerk/dev globally, you'll need to initialise a configuration file and tell the CLI where to find your local copy of the clerk/javascript repository.

1. Initialise the configuration file which will be located at ~/.config/clerk/dev.json:

   ```shell
   clerk-dev init
   ```
   

2. Navigate to your local clone of clerk/javascript and run set-root:

   ```shell
   clerk-dev set-root
   ```
   

You're all set now to run the day-to-day commands 🎉

During the first time setup a ~/.config/clerk/dev.json file was created. Its object contains a activeInstance and instances key. You can add additional instances by adding a new key to the instances object.

You can use the set-instance command to switch between activeInstance afterwards:

clerk-dev set-instance yourName

In each project you'd like to use with the monorepo versions of Clerk packages, clerk-dev can perform one-time framework setup such as installing the monorepo versions of packages and configuring the framework to use your Clerk keys.

To perform framework setup, run:

clerk-dev setup

If you aren't working on @clerk/clerk-js, and do not want to customize the clerkJSUrl, pass --no-js.

clerk-dev setup --no-js

If you want to skip the installation of monorepo versions of packages, pass --skip-install.

clerk-dev setup --skip-install

Once your project has been configured to use the monorepo versions of your dependencies, you can start the watchers for each dependency by running:

clerk-dev watch

This will run the build task for any @clerk/* packages in the package.json of the current working directory, including any of their dependencies.

If you do not want to start the watcher for @clerk/clerk-js, you can instead pass --no-js.

clerk-dev watch --no-js
