I have the same issue using VS Code for a NestJS + Mongoose server project. The same solution mentioned in several answers above, with a twist: Put it in the eslint.config.mjs` (extension can also be js or whatever you are using for eslint.config.

Put the following in the `rules` object:

rules: {
    ...
    "prettier/prettier": [
        "error",
        {
            "endOfLine": "auto"
        }
    ],
    ...
