Prettier Integration

It'd be nice to integrate Prettier into Wild Web Developer to enable features such as CSS formatting.

Originally, I wanted to propose having a Node.JS project builder, which would use the embedded Node.JS instance from Wild Web Developer to allow running Node applications as a build action. This would allow users to create a package.json for their workspace, add prettier as a dev-dependency and run prettier to format on save/automatic build.

However there are issues with this approach:

• A user might want to format CSS and not use a package.json
• Most users who would want to run Node tools such as prettier will most likely have Node on their system. Using the internal/embedded Node from Wild Web Developer might cause differences/issues, and there is a maintance cost for adding options (such as use internal/external node for Node.JS project builder)

So instead, it might be desirable to integrate Prettier directly into Wild Web Developer, and have it run on format.

Prettier is configurable with a configuration file, which will give users nice options such as ignoring certain files when formatting, using single/double quotes, etc.

Prettier is already being used in Spectrum Theme as a project build action.

Beginnen Sie mit der Prüfung der vorgeschlagenen package.json sowie der Einstiegspunkte für format-on-save oder automatische Builds; das Issue nennt keine spezifischen Repository-Dateien oder Tests. Lesen Sie anschließend die Konfigurations- und Optionsdokumentation von Prettier und legen Sie fest, wie die direkte Integration die Formatierung ausführen und die Projektkonfiguration berücksichtigen soll, bevor Sie sie implementieren.
