wrangler init should populate example code

[Electroid]

After running wrangler init, no example code is provided (index.js or index.ts depending if they asked for TypeScript or not). It should populate a basic starter file. In the future, we can make this more complex by introducing different templates to choose from.

src/index.ts:

export default {
  async fetch(request: Request, env: Environment, ctx: ExecutionContext): Promise<Response> {
    return new Response("Hello!");
  }
}

export type Environment = {
  // MY_NAMESPACE: KvNamespace;
}

src/index.js:

export default {
  async fetch(request, env, ctx) {
    return new Response("Hello!");
  }
}

Also, should probably have a comment that links to the reference documentation?

Instead of asking wrangler init to do this. We should push ahead with implementing the create-workers-app package, which could then be run using npm init workers-app. See https://www.npmjs.com/package/create-qwik for an example of how this can work.

I'd like to push back on this, it'll become extremely complicated to keep adding features here. But this is what we were planning on doing with create-worker-app, and we should design and plan that separately.

Both great points. I do like the idea that we can just guide folks to create-workers-app. In fact, maybe wrangler init is just a legacy alias that asks if they want to run it?

My only qualm is leaving wrangler init half-baked; the entry point seems like a trivial addition that would make the experience much more useful. I agree the more complicated stuff can be left for a separate tool, but without the entry point, you feel like you got dropped off halfway to your destination.

I like the idea of an entry point. Ok let's try something and see how it feels.
