Description

Fixes #23513.

From @leoloso:

When compiling a block using the @wordpress/create-block package with npm start, and having this dependency, it throws an error

The problem happens in this piece of code:

if ( ! isProduction ) {
	// WP_DEVTOOL global variable controls how source maps are generated.
	// See: https://webpack.js.org/configuration/devtool/#devtool.
	config.devtool = process.env.WP_DEVTOOL || 'source-map';
	config.module.rules.unshift( {
		test: /\.js$/,
		use: require.resolve( 'source-map-loader' ),
		enforce: 'pre',
	} );
}

And the solution is just to exclude this rule from the node_modules folder.

How has this been tested?

npm start in the test plugin.

@gziolo gziolo force-pushed the fix/exclude-node-modules-source-map branch from 1a646e2 to b93c82b Compare July 6, 2020 11:18

Is this intended? Just want to make sure we have a way to debug wordpress packages on Core. (not sure this has an impact though, Core might not use wordpress/scripts yet)

There is completely separate process in WP Core, even when we use @wordpress/scripts we will use a custom webpack config. It shouldn’t have an impact.
