Excellent, this looks great and is more than enough for v1. We probably should also update https://github.com/WordPress/gutenberg/tree/trunk/packages/scripts#build and https://github.com/WordPress/gutenberg/tree/trunk/packages/scripts#start to reflect all the changes. Let me try to apply changes directly to the branch. |

Good catch 👍🏻
Aside: Sharing for inspiration. It would be great to remove that limitation/exception and offer an alternative way to enqueue those view scripts on demand. Related Track ticket: https://core.trac.wordpress.org/ticket/56470.

Yes, something like that would be neat 🙂

By default, only PHP files listed in the
renderfield in the detectedblock.jsonfiles get copied.
As I understand from #42430 the new render field in block.json only accepts a path for just one file.
Shouldn't this say something like...
By default, only the PHP file defined for the
renderfield (if any) in the detectedblock.jsonget copied.

There might be multiple block.json files.

In that case, it's perfect in the way it's written 👍

Yes, I see what you mean. It's hard to explain as it's one file per render, but it might be in multiple block.json files processed.

I use wordpress-scripts in our build system, and it doesn't work anymore. The whole thing is more complex, but basically, there is what it does: https://github.com/loxK/wordpress-scripts-test
import wpWebpackConfig from '@wordpress/scripts/config/webpack.config.js'
import CopyWebpackPlugin from 'copy-webpack-plugin'
import {resolve} from "path";
export default {
...wpWebpackConfig,
entry: './dir/file.js',
output: {
filename: 'file.js',
path: resolve( process.cwd(), 'assets/js' ),
},
plugins: [
...(( wpWebpackConfig?.plugins || [] ).filter(plugin => ! (plugin instanceof CopyWebpackPlugin))),
]
}» npm run build
> build
> webpack
[webpack-cli] Failed to load '/home/www/test/webpack.config.js' config

Hey @loxK. I've just cloned your repository, done a npm install (using node 16) and npm run build, and it worked fine.
I'm not sure what may be going on. Could you please try removing the node_module folder and running npm install again? Or giving us more precise instructions to reproduce the problem?

You need to upgrade @wordpress/scripts to 24.1.0 by editing packages.json and npm i, in the repository the wordpress-scripts version is fixed to 24.0.0.
I upgraded it in the repository, git pull it and npm i

Gotcha.
For some reason, process.env.WP_SRC_DIRECTORY is undefined in your configuration. I'll investigate why.
It wasn't failing before because you overwrote the entry points (which also access process.env.WP_SRC_DIRECTORY).
There was a problem hiding this comment.
Ok, it's because you're using "build": "webpack" and not "build": "wp-scripts build" in your package.json.
wp-scripts build initializes process.env.WP_SRC_DIRECTORY:

I'm sorry, but I don't know the answer. You need to find a way to switch back to wp-scripts, or you'd have to take a look at its internals to understand what it's doing before it loads webpack to do that yourself. You're also welcome to open a PR if you think there's something broken inside wp-scripts 🙂

Damn breaking change in a minor release version number. Hours of work ahead ...
That sucks.

Extending webpack is not covered with semver, especially when not used in conjunction with wp-scripts.
Future versions of this package may change what webpack and Babel plugins we bundle, default configs, etc.

By the way, if you have needs that wp-scripts don't support yet and you think they'd be useful for a wide range of people, I encourage you to open an issue/PR to add those improvements to wp-scripts 🙂
I also encourage you to open a PR if you think there's something broken or that could be done in a better way inside wp-scripts.

For reference, @loxK opened a PR to change the way the webpack config access the value of process.env.WP_SRC_DIRECTORY:

What?
Thanks to this recent Pull Request, now you can use a PHP file, defined in the
renderprop, instead of the traditionalrender_callbackfunction. This PR aims to add that file automatically to the build folder, which isn't happening right now.Why?
As discussed here, right now it seems possible to do it manually, but it should work automatically.
How?
We changed the WebPack configuration to detect and copy the
.phpfile defined in theblock.json:webpack.config.jsfile to differentiate between JS and PHP files. In this second case, we are just filtering the PHP files to include only the one defined in therenderprop, unlessprocess.env.WP_COPY_PHP_FILES_TO_DISTis set to true.getRenderPropPaths), to retrieve the file paths of all therenderprops defined in the blocks. This is used to compare in thewebpack.config.jsfile.Thanks @luisherranz for the help figuring out how this should work.
Testing Instructions
Not sure what is the best way to test it in the Gutenberg plugin. I found this problem working on custom blocks in an external plugin (in the BHE repo), and I tested the code there. After adding this code, the
render.phpfiles were included in the build folder.
