Is there a simple replacement for @providesModule?

See original GitHub issue

Do you want to request a feature or report a bug?

Feature request, I think?

What is the current behavior?

I can no longer import myClass from "MyClass"; where said class contains @providesModule myClass.

I’m not sure if this is the right place to ask, but a commenter over in this issue suggested to ask the Metro team. I’ve used @providesModule since I started with React Native (~3 years ago) and now have a massive project. I’m looking to upgrade to the latest React Native version, but since @providesModule has been removed I’m not sure how to migrate my code base, short of modifying thousands of import statements.

Is there a way to easily enable this type of functionality?

Okay, that branch linked in my previous comment has been updated and is now a full working example!

Thanks Rubén, I wasn’t able to find detailed documentation on this, but I see the property now specified in the Metro documentation. I’ll take a look.

We removed the support for @providesModule by default but you can use global modules the same way using the option. You can see an example here: https://github.com/facebook/metro/blob/cdc9cbe89c9966a25314cc13971e547c12e9227a/packages/metro/src/DeltaBundler/__fixtures__/hasteImpl.js

I recommend you not to read the file to get the haste name from the @providesModule tag but extract it from the file name, as we do now at Facebook.
