A Serverless plugin design to make it possible to use Serverless in a
Javascript mono repo with hoisted dependencies, e.g. when using Yarn Workspaces.

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!

Installation

``yarn add --dev serverless-plugin-monorepo

`or using NPM`


npm install --dev serverless-plugin-monorepo


Currently this plugin requires Node V10+. If there is interest in support older
versions then trans-compilation with Babel could be added.

Usage

Add the plugin to your serverless.yml file:

`plugins: - serverless-plugin-monorepo`

The plugin listens for package lifecycle events. Prior to Serverless packaging up the service, it will scan thepackage.jsonfile for dependencies and ensure that all dependencies (including transitive dependencies) are symlinked innode_modules.

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: - A full deployment (sls deploy) - Deployment of individual functions (sls deploy -f) - Spinning up a local sandbox with serverless-offline (sls offline [start])

`Settings`

On Windows platforms only, the package will create junction links by default as these do not require administrative privileges on older versions of Windows. You can set thelinkType setting to dir to create symbolic links instead. This setting is directly passed to the fs.symlink function. It is ignored on non Windows platforms.

`Contributing`

We welcome issue reports and pull requests!

There is a small runscript which will launch Node V14 in a Docker container which you may find useful for development purposes.

Note we are using Prettier with Typescript ESLint and you can run the lint tool viayarn lint` which will attempt to automatically issues like spacing etc.
