Expo Web Support

[tyrauber]

In order to build the example for expo web, a couple changes might be required:

a) should use metro for the web bundler:

    "web": {
      "favicon": "./assets/favicon.png",
      "bundler": "metro",
      "output": "static",
    },

b) resolve .mjs files in metro.config.js (Zod requires it)

config.resolver.sourceExts.push('mjs');

c) NativeModules.SourceCode.scriptURL isn't cross-platform, therefore you might need to explicitly define the hostname / url through an env variable or find a cross platform method, perhaps in expo constants.

electric/examples/expo/src/config.ts

Line 2 in 4682c4a

const { hostname } = new URL(NativeModules.SourceCode.scriptURL)

---

Unfortunately, web still errors with a require cycles:

Require cycle: ../../node_modules/electric-sql/dist/migrators/index.js -> ../../node_modules/electric-sql/dist/migrators/bundle.js -> ../../node_modules/electric-sql/dist/migrators/index.js

Require cycles are allowed, but can result in uninitialized values. Consider refactoring to remove the need for a cycle.

Thanks for this, we'll take a look.

Happy to help, @thruflo. Really excited about this project. Working off of expo example. Let me know if you have any questions. I'll keep experimenting.

@tyrauber did you manage to fix the issues for your own needs?

Moving this into a discussion so we can track it as a feature request.
