@vue/eslint-config-prettier

A wrapper around eslint-config-prettier designed to work more intuitively with create-vue setups.

This config is specifically designed to be used by create-vue setups and is not meant for outside use (it can be used but some adaptations on the user side might be needed - for details see the config file).

A part of its design is that this config may implicitly depend on other parts of create-vue setups.

Installation

npm add --dev @vue/eslint-config-prettier

Please also make sure that you have prettier and eslint installed.

Usage

Note: the current version doesn't support the legacy .eslintrc* configuration format. For that you need to use version 9 or earlier. See the corresponding README for more usage instructions.

Import @vue/eslint-config-prettier in eslint.config.js (or eslint.config.mjs), and put it in the configuration array – after other configs that you want to override.

import { defineConfig } from "eslint/config";
import someConfig from "some-other-config-you-use";
import prettierConfig from "@vue/eslint-config-prettier";

export default defineConfig([someConfig, prettierConfig]);

Make sure to put it last, so it gets the chance to override other configs.

This configuration is the most straightward way to use ESLint with Prettier.

It disables all rules that are unnecessary or might conflict with Prettier. It also enables the eslint-plugin-prettier plugin, which runs Prettier as an ESLint rule and reports differences as individual ESLint issues.

By default all formatting issues are reported as warnings, and will be automatically fixed during eslint --fix.

Use Separate Commands for Linting and Formatting

While the above setup is very straightforward, it is not necessarily the best way.

Running prettier inside the linter slows down the linting process, might clutter the editor with annoying warnings, and adds one layer of indirection where things may break. Prettier's official documentation recommends using separate commands for linting and formatting, i.e., Prettier for code formatting concerns and ESLint for code-quality concerns.

So we offered an additional ruleset to support this workflow:

import { defineConfig } from "eslint/config";
import someConfig from "some-other-config-you-use";
import skipFormattingConfig from "@vue/eslint-config-prettier/skip-formatting";

export default defineConfig([someConfig, skipFormattingConfig]);

Formatting issues won't be reported with this config.

You can run prettier --check . separately to check for formatting issues, or prettier --write . to fix them.

Further Reading

The default config is based on the recommended configuration of eslint-plugin-prettier, which also depends on eslint-config-prettier. Please refer to their corresponding documentations for more implementation details.
