Sorry if this has been asked before… How can I use a local BJS repo in my project?
I’ve made some changes in _~/Babylon.js_, and built them with `npm run build:dev`. The _~/Babylonjs/packages/dev/core/dist_ directory has the updated files, but how to get _~/myproj_ to use this build?
Here’s _~/myproj/package.json_:
```
"dependencies": {
"@babylonjs/core": "../Babylon.js"
}
```
After `npm ci`, the _node\_modules/@babylonjs_ directory exists, but it doesn’t have my changes.
I’ve hacked around this by copying the updated files to node\_modules, but there has to be a better way

npm-link to the rescue.
The process is described here - [Start Contributing to Babylon.js | Babylon.js Documentation](https://doc.babylonjs.com/contribute/toBabylon/HowToContribute#the-build), search for " Link a public project to an external one" (sadly i can’t provide a direct link to this part of the docs). You don’t need to run the prepublish step, this is now done automatically for you.
In general - you can use npm-link to link any public package using this method.
