[jtg-gg]

Roger Wang, this is my pull request for the auto updater
this will also needs nwjs/chromium.src#66

The squirrel windows auto update is included, in this commit
the windows version can be done in javascript only, it will do IPC with the squirrel updater

[rogerwang]

Great. Thanks! Will look to merge it. CC #233

[rogerwang]

Please include documentation change as well.

[jtg-gg]

ok @rogerwang, will do it within this 1-2days

[jtg-gg]

the documentation is done (included in this pull request)
https://github.com/jtg-gg/node-webkit/blob/nw20-autoupdater/docs/References/AutoUpdater.md

[rogerwang]

I see the docs comes from http://electron.atom.io/docs/api/auto-updater/ with modifications.

After PR merged, is NW supposed to work in the same way as described in the doc? There are several external tools mentioned in the doc, including electron-winstaller, electron-builder, grunt-electron-installer, nuts, squirrel-updates-server, squirrel-release-server. Are they tested to work with this PR? -- just want to know what has already been tested on your side and I'll try the others.

[jtg-gg]

@rogerwang my implementation was closely following the electron api, with very little modification.

as for the windows installer, I personally have tried electron-wininstaller, and it works with nw.js
I haven't try the other 2 windows packager

as for the server, I was trying squirrel-updates-server, but it is too complicated for my test / needs
at the end I setup my own http server. The other 2 sever, I never tried

Is this going to be integrated into nw.js anytime soon? Would be great to have squirrel delta updates, but if not will roll my own updater...

[oaleynik]

@rogerwang do you think this can land any time soon? 🙏🏻

[vinaynb]

@sashahilton00 did you manage to create your solution for delta updates ?

[Ajeey]

@rogerwang Any update on when are you merging the PR? Auto update, specifically delta updates is crucial for a desktop app. This functionality alone could be a deal breaker when choosing between nwjs OR electron.

[vinaynb]

@rogerwang any updates on this ? This is a must for my use case as i don't need to update nw binary itself, just the app code.

[rogerwang]

@vinaynb this is about updating NW binary, not the application code.

@Ajeey currently there are solutions for auto-update as an add-on. So we are not in a hurry to make it as built-in feature. For this PR, we are waiting for an implementation for Windows as well.
