Does not work with plugin-typescript

[frederikschubert]

When trying to use plugin-typescript the chrome tab hangs with 100% CPU usage.

[alexisvincent]

Are you able to identify the problematic area?

[frederikschubert]

It seems to hang at this request:

http://localhost:8000/node_modules/sha.js/index.js

[alexisvincent]

I get the same issue. What makes you think its that request?

[frederikschubert]

I now disabled caching and the first request that stays in a pending state is http://localhost:8000/node_modules/inherits/inherits_browser.js.

[frederikschubert]

This is really hard to debug, as the browser freezes as soon as I include plugin-typescript.

[alexisvincent]

Try with throttle

[alexisvincent]

Leaving to go home. Will check again there

[frederikschubert]

Alright. I will try to debug it further tonight. I just noticed that the lock file still contains the urls to my company's proxy. :) So that will probably have to change.

[alexisvincent]

I just deleted it. Im going to try now with the jspm package override and see if that works

[alexisvincent]

This is failing for me as well. It might have something to do with overrides... If you want to manually apply overrides, just copy them out of the jspm registry and add them to the package.json of the packages before doing a config gen.

[frederikschubert]

So I narrowed it down to jspm-nodelibs-buffer and/or jspm-nodelibs-string_decoder. I added the nodelibs one by one and when I added either one of these the error occured.
Without them, the application (obviously) does not run, but the browser does not freeze either.

Update

When I only load this file through systemjs, the browser freezes:

require('jspm-nodelibs-buffer');

Update 2

When I install the newest version of https://github.com/feross/buffer directly, the browser does not freeze anymore.

But now it hangs at:

require('jspm-nodelibs-string_decoder');

[alexisvincent]

Thanks for tracking this. I'll play with it in a bit. Did you install from github or npm?

[frederikschubert]

I tried both. string_decoder depends on the global Buffer object. So maybe the buffer package still is the problem and my mapping did not work as intended.

[alexisvincent]

I'm doing some funky stuff with that. Look at the systemjs-nodelibs

[frederikschubert]

I see. When installing systemjs-nodelibs I get some warnings from yarn/npm:

warning Unmet peer dependency "util@jspm-nodelibs-util@^0.2.0".
warning Unmet peer dependency "assert@jspm-nodelibs-assert@^0.2.0".
warning Unmet peer dependency "http@jspm-nodelibs-http@^0.2.0".
warning Unmet peer dependency "process@jspm-nodelibs-process@^0.2.0".
warning Unmet peer dependency "process@jspm-nodelibs-process@^0.2.0".

Will check this out in an hour or so

[alexisvincent]

Sorry for the delay, busy weekend, with too little time.

The peer dependency issue is because JSPM internally uses a non standard npm package dep convention, since they assume that it will only be installed using JSPM. I want to try make this cleaner. Also now that you and Guy have pushed npm package updates, we can probably use those instead, which will speedup yarn installs since it doesn't need to resolve the github package every install.

[alexisvincent]

Any progress on the source of the bug?

[frederikschubert]

No worries :) No, unfortunately I could not find it.

[alexisvincent]

I'll try play some more today.
