Manifest v3 about browser-extension-template HOT 15 CLOSED

FYI for anyone looking for a hacky immediate workaround, you can manually patch the @parcel/transformer-webextension module via https://github.com/ds300/patch-package to recognize the new schema. It worked for me in lindylearn/unclutter@3bc830e.

from browser-extension-template.

The PR has been merged. Try running this in a few hours:

npm install -D parcel@nightly @parcel/config-webextension@nightly

from browser-extension-template.

Thanks for the ping! I updated parcel, tested it and it works as expected!

Note

This change effectively drops support for Firefox until they support Manifest v3: https://bugzilla.mozilla.org/show_bug.cgi?id=1578284

To enable support manually:

1. Run npm run build
2. In the distribution/manifest.json file, revert the same changes you see in #75:
   • set manifest_version to 2
   • move host_permissions items back to permissions
   • restore the previous background key
3. Save that version just for Firefox

Please leave a 👍 on parcel-bundler/parcel#6079 if you're interested

This is still a problem, and apparently the Chrome Web Store has stopped accepting new Manifest V2 extensions. Does this mean we cannot publish extensions that have been written with this template?

Thank you, I have liked the issue you suggested.

from browser-extension-template.

I'll keep this open until I update Parcel here if you don't mind.

from browser-extension-template.

Thanks for opening the issue!

The issue is that Parcel does not support the Manifest v3 yet so the only way to use v3 is to use webpack (or to avoid the WebExtension transformer, which would change the template substantially). This is tracked in parcel-bundler/parcel#6079 and there's nothing that can be done in this repo unfortunately.

You have until early 2022 to publish your v2 extension and then Parcel hopefully will update the transformer to support v3 before the "end of life for v2" in 2023.

If it's urgent, your only choice is to use a previous, webpack-based version. This is the last one before moving to Parcel: https://github.com/fregante/browser-extension-template/tree/a0f9cbe27c854e98d52033783a9e951246217dab

👆 but it's not advised at this point.

from browser-extension-template.

Unfortunately correct. There has been a PR on parcel's repo open for a while to add support

from browser-extension-template.

I see from this comment 3 days ago that apparently all the work is done, and it's just awaiting final review. Does this mean that until it's merged we can in theory just specify a dependency on the GitHub PR branch?

from browser-extension-template.

Hrm, maybe not, since @parcel/transformer-webextension is a separate package in a workspace subdirectory, and I can't see any obvious way to specify a dependency on a subdirectory of a GitHub branch. I notice that this StackOverflow question seems to ask how to do that, and didn't get any answers in 9 months, so maybe it's just not possible and ds300/patch-package is the best way.

from browser-extension-template.

Monorepos are a mess of tangled dependencies so I'd advise against trying to load that separately 😳

Hopefully they're only a few days away from merging…

from browser-extension-template.

OK thanks for the advice! Yes hopefully indeed, since I'm working on an extension which I'd love to have published in the Chrome Web Store before a conference coming up soon...

from browser-extension-template.

You can see the progress in the PR #75

However unfortunately it doesn't work due to:

• parcel-bundler/parcel#7952

from browser-extension-template.

What is left to do on this?
