Example of using closure_js_binary to bundle an Angular application?

[pshields]

Hi Alex! I'm attempting to develop some applications on the Angular+Bazel+Closure stack, and I'm running into the issue of lacking a build rule to produce the JS application bundle. I see from the wiki's "Coming soon" section that there will soon be "a production bundling/optimizing rule that generates a distribution of the app (or library)". Is the plan to modify the closure_js_binary rule to support that? Can you share a little bit more about what needs to be done to get that working?

The current issue I'm running into when I try to use the closure_js_binary rule is that when I add an ng_module target as a dependency, I get ERROR: [...] 'app_module' does not have mandatory providers: 'closure_js_library'. I notice a similar error occurs when I check out the closure_js_binary branch of this example repository and attempt to build //src:prod_bundle.

It's exciting to be able to build on this stack. Thanks for the contributions you're making to make it possible.

bazelbuild/rules_typescript#74 is the next step.
Once we have that, I think compiling an Angular app won't be too hard since we already do it in google3 and this stack is very similar.

I think @mrmeku is going to own this, and we'll do a hackathon in MTV the week of Dec 18 to put together a working prototype. Want to participate?

I'm no longer in MTV, but I'd be happy to help out online to the extent that I can. I don't have much experience implementing rules in Skylark and interacting with the Closure rule internals, but I can try to take on some smaller well-defined tasks or give feedback when trying to consume the rules from my projects.

The more the merrier!

Let's track it in bazelbuild/rules_typescript#6

We'll naturally add an example as part of landing a major feature
