[Thali-talk] 'self' support to JxCore?

[Yaron Goland]

Sreejumon, can you please load the Bluebird project into something like webstorm and find where Bluebird defines self. How does that code work? That should help us narrow down the cause of the bug.
               Thanks,

                              Yaron

AFAIK the jxcore users don’t have an issue with bluebird.

I’ve just test jxcore SM with bluebird sample app and it worked straight.

Hi Yaron,

The failure is from catptured_trace.js file.

Note: I’m moving this thread to the public alias.

Issue: We are using Bluebird as part of Express-PouchDB and when we run it on JXCore it fails because it expects to find a ‘self’ variable. Sreejmon is working around this by setting “global.self = global” but he is wondering if this is a more general problem.

Oguz pointed out that this is a browser thing, Node doesn’t do this and therefore Bluebird might be confused about where it is running.

Oguz: Bluebird is a very widely used library so my guess is that if it’s confused then it’s likely to be because JXCore isn’t doing something it is expecting. Something like that isn’t going to just bite us here.

Sreejumon: What line did the request fail on? I did a search https://github.com/petkaantonov/bluebird/search?utf8=%E2%9C%93&q=self+extension%3Ajs+path%3Asrc&type=Code and self only seems to be used in a few places.

               Thanks,

                              Yaron
