Support Yarn Berry

[yovanoc]

Hello, I don't know if its a bug report or feature request but I can't use next-offline with yarn berry.

The first next build gives me that:

So I've added webpack myself (yarn add -D webpack)

then here it is for the last build and I don't know what to do, thanks

@yovanoc the error seems to be caused by the workbox-webpack-plugin https://github.com/GoogleChrome/workbox/issues/2669 . So most probably just upgrading the package in this repository should do it. Otherwise you could try yourself by using resolutions in package.json but I haven't tested it out myself yet.

We are seeing this too. I am adding the error message as text here because right now it is not indexed by any search engines.

I think the issue is caused by trying to write into __dirname at https://github.com/hanford/next-offline/blob/master/packages/next-offline/index.js#L88 which with yarn 2/pnp is a zip file and not a writeable location.

Edit: I tried a quick fix here https://github.com/bjorm/next-offline/commit/56524803893925df39c0c5f53f4a395046ec391f So far the build completes successfully. I need to make sure that it actually works when deployed.

If other people want to try this fix, use the yarn patch protocol in your package.json:

"jest-junit": "^9.0.0",
"next-offline": "patch:next-offline@^5.0.2#./next-offline.patch",
"next-svgr": "^0.0.2",

where next-offline.patch contains
