Module resolution for local dev about react-native-wix-engine-playground HOT 5 CLOSED

Hey @ajzozakiewicz,

The resolving is done by the name of the module in the "name" section in your package.json and the "main" section which should point to the module.js file.

  "main": "./src/module.js",
  "name": "wix-engine-playground-module-blog",

I hope it answers your question.

from react-native-wix-engine-playground.

Sure, when wix-engine-playground-module-blog is installed as an NPM module it will resolved that way. Will the metro bundler know to resolve it though for local dev? When I say local dev, I am in the module-blog repo, running rn-wix-engine -p engineConfig.json -i. engineConfig.json contains a ref to "wix-engine-playground-module-blog".

When running within module-blog how does the metro bundler know to resolve this to the local folder rather than "wix-engine-playground-module-blog" from node_modules?

So I am looking at this config:
https://github.com/wix-incubator/react-native-wix-engine-playground/blob/main/module-blog/engineConfig.json

And running npm run ios here:
https://github.com/wix-incubator/react-native-wix-engine-playground/blob/main/module-blog/package.json

Hope this clarifies my question. Kind of hard to explain. Appreciate the help.

Using a babel transform I am sure you could resolve any refs to the local project folder, but I didnt see any special transforms for this to work.

One of the search paths of metro is the current module, so wix-engine-playground-module-blog not have to be in your node_module folder but in one of the following:

myProject/
myProject/node_modules/
myProject/node_modules/@scope/
/usr/local/lib/node_modules/
/usr/local/lib/node_modules/@scope
/usr/local/lib/node_modules/npm/node_modules/
/usr/local/lib/node_modules/npm/node_modules/@scope
$HOME/.npm/
$HOME/.npm/@scope/

Awesome, that makes perfect sense now. Guess I need to get in a better habit of reading source code...

Thanks for pointing me in the right direction on this one.
