Transfer-files example crashes when initiating a node

[gediminasml]

Clicking on the Start IPFS button shows the following error:

Uncaught TypeError: getLevelDOWN is not a function
    at LevelUP.open (ipfs.js:47646)
    at new LevelUP (ipfs.js:47619)
    at LevelUP (ipfs.js:47579)
    at new LevelDatastore (ipfs.js:37876)
    at new IpfsRepo (ipfs.js:89813)
    at module.exports (ipfs.js:153886)
    at IPFS (ipfs.js:153937)
    at HTMLButtonElement.start (app.js:37)

And, well, the app just crashes.
I built IPFS from the latest master, also tried building from d7c9eec - no success. Any ideas what's wrong?.

EDIT: f876171 building from this commit seems to solve this issue. However, it's still not working in the latest master branch

Investigating this. Where is f876171?

[daviddias]

Seems it was this change: Level/levelup@6bcd959

[daviddias]

I've narrowed down the issue to the calls of levelDown, which don't exist:

• https://github.com/Level/levelup/blob/master/lib/levelup.js#L114
• https://github.com/Level/levelup/blob/master/lib/levelup.js#L385

The second issue I'm having is that levelup is required by a bunch of dependencies at different versions and webpack keeps picking at least one that causes the issue.

[daviddias]

I've opened an issue at Level/levelup#426 to report this problem.

I've been trying to circumvent this issue by requiring a specific commit of levelup, but unfortunately, since there are several deps and deps of deps that require that module, it is being hard to get rid of that patch version from being bundled in, making it always fail.

I'll give this 24 hours with hope to have a fix on levelup, otherwise, I'll look into other ways to solve this issue.

Thanks for looking into this, @diasdavid! Sorry for not getting back to you - timezone differences 🕐
Do you need any further clarification?

[daviddias]

Fix incoming \o/

Now last thing missing is this Object.assign issue, I created a q in stack overflow for it, as its nature is so strange.

[daviddias]

I believe I know what is going on, Object.assign works well everywhere except in js-ipfs, which means that there is some js-ipfs dep that is remapping that global 🙀.

Does anyone have a tip to find that remapping quickly?

[daviddias]

Oh, I know!
