Update: the initial article was plaing wrong :) I fixed it now. The important change is that you need to npm link the dist folder, not the root folder of the plugin project.

So, the question arises when you want to change a module that is used (and tested) in another module. Let's say your normal flow is to change the version of the child package, then npm run packagr, then npm publish it, then npm install childModule@latest in the parent app. This quickly gets tiresome and leads to unrealistic version numbers.

A better solution is to use npm link. First, you go to your plugin/child module and you run npm run packagr. When it's done, go to the dist folder and run npm link. This will create a symlink in the global node_modules folder for your project's distribution package. Then, move to the parent module and run npm link <name-of-child>. The name of the child is the same as the name of the application. This creates a symlink in the parent module's node_modules to the global symlink created earlier.

Wait! A few gotchas, first:
  • careful with the operations that might change the content of the folder linked in node_modules, as they will change the actual source code of the plugin
  • after you finish with the work on the plugin, then delete the symlink, publish the child and reinstall @latest at the parent
  • make sure that the version of the plugin package in the parent is permissive (something like >=initialVersion), otherwise you might have problems with the version number you set in the plugin package.json file

Hope this helps.

No command &#39;nom&#39; found, did you mean: Command &#39;npm&#39; from package &#39;npm&#39; (universe) (title typo ;-))
