Lerna monorepo example

This is an example monorepo that uses lerna. There are two packages in the repo: workspace-c, and workspace-d. Both packages start HTTP servers using yarn serve, each returning different responses.

Local Testing

1. Start at the repo root
2. Run yarn install to install all dependencies
   • Note that package.json contains a postinstall script that runs lerna bootstrap.
   • This instruct yarn to run lerna bootstrap after yarn install has finished. This allows lerna to install any required dependencies and also link the workspace-c and workspace-d packages. By doing this as part of the install step, App Platform can cache the dependencies installed by lerna.
   • Important: if you do not configure a similar postinstall command, you will need to manually run lerna bootstrap.
3. Change into either workspace directory:
   • cd packages/workspace-c; or
   • cd packages/workspace-d
4. Run the example build command: yarn build
5. Start the server: yarn serve

Deploying to App Platform

1. Select your git repo
2. Keep the source directory set to the default, /
3. Set the build command to:

   yarn bootstrap
   cd packages/workspace-d
   yarn build
   

4. Set the run command to:

   cd packages/workspace-d
   yarn serve
