Addon support

[joostdevries]

• Stabilize addon API
• Nice addon loading indicator
• Auto reload/refresh after addon build completes
• Handle addon build errors
• Handle addon config in twiddle.json
• Handle multiple ember / ember-template-compiler versions

Any thought regarding docs or usage instructions so far ? Wondering how to use addons now myself :D

Once addons are supported properly, we will add a section in twiddle.json.

@Gaurav0 @alexspeller an update on addons:

The current addon system builds addons in Docker containers on top of Amazon ECS. Basically I've created an API endpoint which - when hit - tries to run the build on ECS. The downside of this is/was that ECS does not handle scheduling so when there are no resources available (it can run max. 2 build in parallel), the build fails.

I've created a custom scheduler which schedules builds on SQS as intermediate step and am currently in the process of placing that in the middle of the system. I expect this to be done this week. The end result should be a very robust and quite secure online addon building system. It has some nice features such as:

• Each build gets temporary S3 credentials limited to it's own 'subdirectory', so a rogue addon install script could never compromise other addons stored in our S3 storage.
• Builds typically run within 30s.
• Builds are queued in SQS and after each successful build we check the queue to make sure builds move as fast as possible.

@Gaurav0 I've began moving everything to the new architecture.

Base URL's for API:

• Canary: https://emw2ujz4u1.execute-api.us-east-1.amazonaws.com/canary
• Production: https://howq105a2c.execute-api.us-east-1.amazonaws.com/production

I expect to finish the migration tonight/tomorrow (Dutch time).

Discovered a new issue: Alpine Linux support is not present for node-sass, sass/node-sass#1589. But they're working on it.

[joostdevries]

We now fully support addons for 2.6 and 1.13 in Ember Twiddle canary (https://canary.ember-twiddle.com). Docs on adding more versions at https://github.com/joostdevries/twiddle-backend

This is awesome!

@joostdevries I created a twiddle with ember-cli-jstree addon but its throwing a security error.
Could you take a look? Maybe I'm doing something wrong

@ritesh83 This is unrelated to addon support. The script tries to load a WebWorker which afaik is not enabled in sandbox mode.
