Issues forking and using locally

[connorpmullins]

Hey all!

I'm having an issue forking rnmapbox and consuming it in a project locally. I don't know if the issue is environment-specific or not, but I'll include that information just in case.

Env. Info

• Forked Mapbox Commit:
  • 4b685a6
• Local Node version:
  • 18.15
• Consuming Project (the app I'm consuming the forked repository in):
  • React Native Version: 0.72.6
    • Note: I am using the new architecture
  • React Version: 18.2.0
  • Expo Version (using bare workflow): 49.0.21

The Issue
When I import my forked rnmapbox/maps repo in my package.json like so "@rnmapbox/maps": "../maps", Android crashes when rendering a Mapbox Map. This issue does not occur when I consume the exact same code imported as "@rnmapbox/maps": "10.1.3".

The Specific Bug

 ERROR  TypeError: Cannot read property 'useContext' of null

This error is located at:
    in View
    in MapView (created by Maps)
    in RCTView (created by View)
    in View
    in Unknown
    in Box
    in Flex

Other Related Information

• This error does not occur on iOS with the same source code and compilation steps
• I have pre-built the forked code using the same steps described in the github publish workflow (this seems to be the root cause most of the time people have related issues)
• I have confirmed that the lib directory exists in the @rnmapbox/maps node_module folder in my project after I import it
• I am on the exact commit deployed to NPM for version 10.1.3
• I've done my best to google related solutions and have been stuck on this for a couple days at this point

I don't believe that the error I'm running into indicates a bug with Mapbox, but as the rnmapbox developers presumably develop the extension locally, I figure this might be a good location to start a discussion on the topic.

Thank you in advance for taking the time to read through this. Hopefully this can help more people than just myself.

I believe that I've resolved this issue for myself.

What I believe what went wrong was this:

• In order to run yarn build locally (required to generate the lib directory), I first needed to run yarn
• After running yarn, a node_modules directory was generated
• That node_modules directory needed to be deleted prior to importing this forked library into my app

Summary of my suggested procedure for everyone running into issues forking this library:

• Fork the library, make sure you're on the commit related to the version you wish to use
• Run yarn followed by yarn build
• Delete the node_modules directory from your forked @rnmapbox/maps directory
• You can now consume this forked library
