Deprecated file format Expo

[jgoodhcg]

It looks like the build process doesn't need to generate files with *.expo.js anymore.

Here is output from the newest expo-cli

➜  mobile-app git:(main) ✗ yarn start                     
yarn run v1.22.10
warning ../package.json: No license field
$ expo start

Project is using deprecated .expo.* file extensions.
Please refactor the following files accordingly:

Dangerously disable this check with EXPO_LEGACY_IMPORTS=1

This isn't at all related to what expo thinks of as .expo.js files.

This just happens to be a shadow.expo CLJS namespace being compiled to shadow.expo.js. This is a regular CLJS namespace like any other where the generated filename is <ns>.js. It is unfortunate that expo doesn't like this but it is not at all about what it thinks it is. Since I don't want to break builds of other people using this I cannot rename this namespace.

This namespace is very minimal https://github.com/thheller/shadow-cljs/blob/master/src/main/shadow/expo.cljs

So you can take it an make a local copy with a "safe" name and use that instead. Nothing in the system expects the name to be shadow.expo. It was just the name I chose. Rename it to whatever and use it in place of the shadow.expo require you have in your app.
