This plugin alleviates the need to use nohoist functionality by creating symlinks to all declared dependencies. Development dependencies are deliberately NOT linked so these will not be packaged into the resulting archive.
Butterwire uses Yarn workspaces and we created this plugin to improve our development experience. Not using nohoist saves wasting disk space and also accidentally including development dependencies in our packaged functions.
Note, this package will only work on operating systems that support symbolic links!
yarn add --dev serverless-plugin-monorepo # or using NPM npm install --dev serverless-plugin-monorepo
Currently this plugin requires Node V8+. If there is interest in support older versions then trans-compilation with Babel could be added.
Add the plugin to your
plugins: - serverless-plugin-monorepo
The plugin listens for package lifecycle events. Prior to Serverless packaging up the service, it will scan the
package.json file for dependencies and ensure that all dependencies (including transitive dependencies) are symlinked in
Hence when Serverless creates the archive, it will follow the symlinks and all dependencies will be added as expected. Development/peer dependencies are ignored.
The plugin will run when you do:
sls deploy -f)
sls offline [start])
We welcome issue reports and pull requests!
There is a small
run script which will launch Node V8 in a Docker container which you may find useful for development purposes.
Note we are using StandardJS and you can run the lint tool via
yarn lint which will attempt to automatically issues like spacing etc.
