Convert yaml to json files

[sergey-shpak]

Hey guys,
Currently I'm using parcel to build web extension and want to store localization files using yaml format.
I'm totally ok to run one more process to convert yaml to json files and then run the main bundling process.
So, the question is - is there any possibility to convert yaml to json using parcel (any kind of configuration options, etc)?

Like https://parceljs.org/languages/yaml/ ?

@mischnic not exactly, I need to convert all the files in directory from yaml into json format (without any usage in js) and later start another process that will include json files into final bundle (which is successfully done by @parcel/config-webextension)

*to give more context, localization files for web extensions are packaged and shipped in extension package and later browser loads those files and provides an API to access the content of those files: https://developer.chrome.com/docs/extensions/reference/i18n/

[mischnic]

So the real problem here is that you want message.json to be yaml files instead?

parcel/packages/transformers/webextension/src/WebExtensionTransformer.js

Lines 86 to 94 in 62f64ca

	for (const locale of await fs.readdir(locales)) {
	if (await fs.exists(path.join(locales, locale, 'messages.json'))) {
	asset.addURLDependency(`_locales/${locale}/messages.json`, {
	needsStableName: true,
	pipeline: 'raw',
	});
	}
	}
	}

@mischnic yes, you got it right!

hey @mischnic any quick suggestions how to achieve this goal?
or it would require additional parcel/webextension development?

[mischnic]

No, it's currently not possible without changes to the Parcel transformer.

@mischnic since it is no doable with configuration only, and it is no something that everyone needs - there is no much sense to change parcel transformer, so I'll go with my custom solution for that particular case, thanks for you help!
