reporters defined on the command line

[aakoch]

I'm not sure which reporters are intended to be added via the CLI through --reporter and which aren't. I tried:

• reporter-build-metrics
• reporter-bundle-analyzer
• reporter-cli

When I tried reporter-cli, it just output the same thing as what was already printed. So, I don't think that is intended for use with the CLI.

reporter-bundle-analyzer didn't give print anything more than running without it and reporter-build-metrics just threw an error:

TypeError: (0 , _utils.generateBundleReport) is not a function
    at Object.report (/Users/aakoch/projects/com/node_modules/@parcel/reporter-build-metrics/lib/BuildMetricsReporter.js:26:70)

    at async run (/Users/aakoch/projects/com/node_modules/parcel/lib/cli.js:369:7)

So are these internal reporters that are not supposed to be used via the command line? And the command line option is for other, external reporters not in the project?

Thanks,

ps. With Yarn the metrics reporter, the error is slightly different:

Yes, reporter-cli is always added when using the parcel CLI:

parcel/packages/core/parcel/src/cli.js

Lines 460 to 466 in b858801

	let additionalReporters = [
	{packageName: '@parcel/reporter-cli', resolveFrom: __filename},
	...(command.reporter: Array<string>).map(packageName => ({
	packageName,
	resolveFrom: path.join(inputFS.cwd(), 'index'),
	})),
	];

@parcel/reporter-bundle-analyzer and @parcel/reporter-bundle-buddy should work:

https://v2.parceljs.org/features/production/#analyzing-bundle-sizes

@parcel/reporter-build-metrics might be broken because it's not really used anywhere though...
