Future issue: upgrade from webpack v4 to v5

[ericblade]

Now that we've had v4 webpack for a few minutes, there's a beta version of webpack v5 that we could migrate to: https://webpack.js.org/migrate/5/

As this requires a bump to node v10, I think we should do this whenever we do the next major version bump

This presently, with beta 15, results in:

ERROR in ./node_modules/get-pixels/dom-pixels.js 3:11-26
Module not found: Error: Can't resolve 'path' in 'C:\src\quagga2\node_modules\get-pixels'

BREAKING CHANGE: webpack < 5 used to include polyfills for node.js core modules by default.
This is no longer the case. Verify if you need these module and configure a polyfill for it.

If you want to include a polyfill, you need to:
        - add an alias 'resolve.alias: { "path": "path-browserify" }'
        - install 'path-browserify'
If you don't want to include a polyfill, you can use an empty module like this:
        resolve.alias: { "path": false }

Following the supplied instructions does not solve the errors. Will re-explore when webpack 5 is out of beta, I think

[ericblade]

it might be possible that webpack v5 will build correctly now that we are no longer building unused node code into the browser bundle and vice versa

[ericblade]

I think webpack v5 is out of beta, and would love to get the latest and greatest working.

fixed in 2.0 branch
