chore(medusa): Re enable plugin loading

[adrien2p]

Summary

This PR re-enables the ability to load resources from external packages through the plugins property in the medusa-config.

Resolves: FRMW-2678

What’s Changed

• Plugin Loading:
  • The plugins property in medusa-config now supports loading resources from external packages from node modules, plugins directory or any other relative path outside of the project.
  • When loading plugins:
    • If the plugin is specified as a relative path and does not exist in the plugins directory of the local project, the system will resolve it using the relative path and will load the resources from either its dist or src directory, depending on how the project is started.
    • If the plugin is specified as a relative path and exist in the plugins directory of the local project, the system will resolve it using the relative path and will load the resources the directory itself
    • If the plugin is specified as an absolute path and/or is part of the node_modules we will load the resources from its dist

Note:

• This update distinguishes between local development plugins and external packages based on their location and path resolution.

Testing

I created and tested a plugin in a local dummy project using the following structure:

• Source code: src.zip

The test plugin successfully loaded and executed the following components:

• API: Added a store route that triggers an event and an admin route.
• Subscribers: Registered a subscriber that listens to the event emitted by the route.
• Jobs: Scheduled a job that executes every second.
• Links: Registered a new link.
• Workflows: Registered a new workflow.

Configuration Used:

module.exports = defineConfig({
  plugins: [{
    resolve: '../plugin-1'
  }],
  /*...*/
})
