I don't know, this workflow means to test the installation and run of Encore on real projects/app.

Do you have something in mind?

Installing the webpack-encore.tgz (packed in a previous step before) here instead of having it in the package.json, prevents the package manager to fails if checksums are different, which was the case for npm/pnpm/yarn pnp.

Will this mean that webpack and webpack-cli will now need to live in the user's package.json?

For webpack yes, but for webpack-cli it looks like it depends of what package manager/script runner the user use.

If you take a look to package.json files used in Yarn PNP and pnpm testing apps, you will notice:

  • the Yarn PNP project need to require (as dev dependency) webpack-cli, otherwise Encore won't be able to run (I don't remeber the issue, but it can be easily reproduced)
  • the pnpm project need to not require webpack-cli, otherwise Encore won't be able to run either 🤔 (and I don't remember the issue aswell)

Maybe Yarn PNP and pnpm have a different way to deal with dependencies's peer dependencies.

yes. But this is necessary anyway as soon as you want to install an extra webpack plugin and being sure that it uses the same webpack version than the one used for the build, which is a must-have. If we want to hide the tool, we need to hide it entirely, which is not the purpose of Encore as it is a configurable tool.

Yep. In our case we need to use the same version of webpack between Encore and Cypress for Component testing, otherwise we got this kind of error:

The situation about webpack-cli is still not clear to me:

A) (?) For non-PNP, you will or won't need to install webpack-cli? Which is it?
B) For Yarn PNP, it MUST be installed
C) For pnpm it must NOT be installed

Will the code in Webpack's executable (https://github.com/webpack/webpack/blob/9fcaa243573005d6fdece9a3f8d89a0e8b399613/bin/webpack.js#L90-L118) effectively enforce whether or not the user will need to install it?

A) For npm (8), If webpack-cli is installed (or not) alongside webpack, then webpack prompts to install webpack-cli:

For A) and C), adding webpack-cli as a peer dependency for Encore does not change anything.
Looks like https://github.com/webpack/webpack/blob/9fcaa243573005d6fdece9a3f8d89a0e8b399613/bin/webpack.js#L34-L57 is broken?

webpack defines the peerDependenciesMeta to mark webpack-cli as optional without adding webpack-cli in peerDependencies. In such case, yarn automatically treat is a peer dependency (accepting any version). I suspect that pnpm does not do the same (and that webpack is then not compatible with pnpm for their CLI bin relying on accessing webpack-cli)

Okay I think I found the issue, when running encore from test_apps/npm, it will use the webpack dependency from Encore project root and not from test_apps/npm, and this webpack dependency does not have webpack-cli installed.

I will push ASAP.

I removed it since webpack already ships webpack-cli as a dev dependency (useful for when developing Encore) and as an optional peer dependency (useful for Encore users).

dev dependencies of webpack have no impact when developing Encore. We are not developing webpack in such situation.

Do I have anything to change here? ATM webpack-cli, in this package.json is present in devDependencies only.
