Eclipse 2021-03: JavaScript formatter settings not working

Question

I can't get any JavaScript formatter settings to work (e.g. setting the tab policy to "Spaces only").

• Fresh download of 2021-03 "Eclipse IDE for Enterprise Java and Web Developers" for Windows
• New workspace
• New "Static Web Project"
• Changed the JavaScript formatter in both the global eclipse settings as well as the project specific settings
• Default include path
• Editing with "Generic Text Editor"
• Ctrl + Shift + F does format the file, but always with some default settings (with tabs)

Answer 1

For JavaScript support there are two alternatives,

• Generic Text Editor by Eclipse Wild Web Developer uses a newer approach by embedding and using the JavaScript/TypeScript language sever from Visual Studio Code
• JavaScript Editor by Eclipse WTP JSDT which is missing in the Eclipse IDE for Enterprise Java and Web Developers, but is the one to which the shown preferences belong; in contrast, it is completely implemented in Java, exists longer and is still alive

To configure the formatter used in the Generic Text Editor, see Angelo Zerr comment:

According this comment, try to

• create in your project root a tsfmt.json
• fill this JSON file like https://github.com/vvakame/typescript-formatter#read-settings-from-files
