Bug or issue?

Please try to answer the following questions:

  • What version of Neutrino are you using? 8.2.3
  • Are you trying to use any presets? If so, which ones, and what versions? "neutrinojs/react": "^8.2.3",
  • Are you using the Yarn client or the npm client? What version? 1.6.0
  • What version of Node.js are you using? 10.0.0
  • What operating system are you using? Ubuntu 16 x64
  • What did you do? neutrino start when there is an unresolved module in a file
  • What did you expect to happen? A reasonable error message
  • What actually happened, contrary to your expectations? I get a massive error message

Occasionally I accidentally import something from the wrong file after some refactoring. Happens. When I run neutrino start, I would expect it to tell me that a certain thing can't be found, but I get a HUGE error message which tells me essentially the same thing. It's slightly amusing but can be annoying at times. I find this typically only happens when imports cannot be found. Example:

julian@wilson:~/Desktop/my-app/my-app-client$ yarn run start
yarn run v1.6.0
(node:18904) [DEP0005] DeprecationWarning: Buffer() is deprecated due to security and usability issues. Please use the Buffer.alloc(), Buffer.allocUnsafe(), or Buffer.from() methods instead.
$ neutrino start
✔ Development server running on: http://localhost:5000
✔ Build completed

And the big one:

My .neutrinorc.js is pretty standard:

module.exports = {

            type: 'image/x-icon',
          },
        ],
      },
      style: {
        loaders: [
          {
            loader: 'sass-loader',

          },
          {
            loader: 'css-loader',
            useId: 'css'

      },
    }],
    (neutrino) => neutrino.config.node.set('Buffer', true),
    neutrino => neutrino.config.plugin('ignore')
      .use(webpack.IgnorePlugin, [/^\.\/locale$/, /moment$/]),
    neutrino => neutrino.config.resolve.modules.add(neutrino.options.source),
    neutrino => neutrino.config.output.set('publicPath', '/'),

Hi! Thank you for filing this issue -- I get these verbose error messages in my projects and they annoy me too! (I should have looked into this sooner haha)

Digging around I found webpack/webpack#818, which said that the error message is only shown when stats: {errorDetails: true}, which we for some reason set here for neutrino start:
https://github.com/mozilla-neutrino/neutrino-dev/blob/e6d1c7198fb39b5659d72640bcba508fea6d8261/packages/dev-server/index.js#L50

We don't set that pref for neutrino build:
https://github.com/mozilla-neutrino/neutrino-dev/blob/e6d1c7198fb39b5659d72640bcba508fea6d8261/packages/neutrino/src/webpack.js#L8
https://github.com/mozilla-neutrino/neutrino-dev/blob/e6d1c7198fb39b5659d72640bcba508fea6d8261/packages/neutrino/bin/build.js#L33-L40

...however the linked webpack issue above says that stats.toJSON() defaults that pref to on, and we use that for the build errors specifically -- which is why neutrino build also ends up being spammy.

The issue is made worse by the fact that Neutrino defaults to having a long list of file extensions (we should probably make .vue and similar only be set if using that preset).

In the meantime a workaround for the neutrino start case is (there isn't one for neutrino build unfortunately):

module.exports = {
  use: [
    [
      '@neutrinojs/react',
      {
        devServer: {
          stats: {
            errorDetails: false,
          },
        },
      },
    ],
  ]
};

Thankfully the build case will be fixed by #852 (which will be in Neutrino 9) - since it switches to using the native webpack CLI tools - so doesn't hand-roll the errors analysis.

However we'll still need to fix the devserver's stats to stop setting errorDetails: true.

@eliperelman, do you think we can backport errorDetails: false for devserver to Neutrino 8 as a fix rather than a breaking change?

@edmorley I'm OK with that, I'd count it more as a bug than a breaking change.

dev-server: Suppress unhelpful stack trace for compile failures (#936)
878ac0d 
This restores the webpack default of not outputting the full stack
trace for compile errors, since it's typically pretty spammy and
doesn't really help with understanding the error.

Fixes #875 for dev-server (#852 already fixed it for `yarn build`).

v8.3.0 has just been released, which includes the fix for devServer (builds will be fixed in Neutrino 9).
