Feature: ServiceWorker support in CLI

[hansl]

Requested by @alxhub.

This is non 1.0 blocking but will be tracked in the 1.0.

For reference for anyone who wants to use service workers with the CLI now its not to much work using the sw-precache library. I have a blog post and working demo here. https://coryrylan.com/blog/fast-offline-angular-apps-with-service-workers

@hansl I notice that this is marked Done in Tracking and I see @alxhub branch here https://github.com/alxhub/angular-cli/tree/sw-support do you have an idea of when this might get a PR? I know you guys are really busy and you are doing a great job, I only ask because I was thinking of trying to figure out some plugin to help server a service worker. So before I get my hands too dirty, I thought I'd be cheeky and see if we are looking weeks or months here?

Awesome, sorry I didn't see it.

I'm having trouble getting this to work... and I feel like it has something to do with the fact that I'm setting --base-href=/SubDirectory/ when I build. Any reason why the service worker wouldn't work when this argument is set?

Maybe this will help: Feature: Route redirection to index.html.

@osnoser1 Thanks for the tip! Are you suggesting I manually update the ngsw-manifest.json file after I build?

[osnoser1]

For now yes. 😃

[alxhub]

@alexjlockwood, create a ngsw-manifest.json file with only the routing config specified in your project root. The generated manifest with file hashes will be merged into it at build time.

[alexjlockwood]

@alxhub Sorry for being a complete noob here, but do you mean like this?

{
  "routing": {
    "index": "/index.html",
    "routes": {
      "/": {
        "prefix": false
      },
      "/ShapeShifter": {
        "prefix": true
      }
    }
  }
}

My web app is here... I'm building it using ng build --prod --base-href=/ShapeShifter/ so that it serves at https://alexjlockwood.github.io/ShapeShifter. Not exactly sure what the desired ngsw-manifest.json end result is supposed to look like though.

[alexjlockwood]

@alxhub Friendly ping. :)

[alexjlockwood]

The problem I seem to be having is that the browser is still trying to retrieve the ngsw-manifest.json file from https://alexjlockwood.github.io/ngsw-manifest.json when it is actually located at https://alexjlockwood.github.io/ShapeShifter/ngsw-manifest.json. Is this something that can be changed via the routing config above?

@alxhub

I think that --base-href=/SubDirectory/ should be concated to the ngsw-manifest.json at routing.index.

Resulting in /SubDirectory/index.html to the sw.

[alexjlockwood]

Just a quick follow up... I ended up filing #5186 and once that got fixed everything seemed to work fine for me.
