Question 1

eslint-config-prettier vs eslint-plugin-prettier, which should I use?

Accepted Answer

eslint-config-prettier disables conflicting ESLint rules to let Prettier handle formatting, while eslint-plugin-prettier runs Prettier as an ESLint rule. They are often used together for full integration, but eslint-config-prettier alone is sufficient if you run Prettier separately.

Question 2

How to set up eslint-config-prettier with TypeScript?

Accepted Answer

Install eslint-config-prettier and @typescript-eslint/eslint-plugin, then extend 'prettier' last in your ESLint config. Use the CLI tool to check for conflicts, and ensure you use the standard plugin name '@typescript-eslint' in flat config to avoid issues.

Question 3

Why is my ESLint still showing formatting errors after using eslint-config-prettier?

Accepted Answer

Conflicts might persist if rules are defined after eslint-config-prettier in your config, or if you're using flat config with non-standard plugin names. Run the CLI helper tool on relevant files to detect and remove such rules.

Question 4

Can I use eslint-config-prettier with Vue.js?

Accepted Answer

Yes, eslint-config-prettier supports eslint-plugin-vue and automatically disables conflicting rules. Extend 'prettier' in your ESLint config, and for flat config, use the standard plugin name 'vue' to ensure proper detection.

Question 5

How do I run the eslint-config-prettier CLI tool?

Accepted Answer

Use the command 'npx eslint-config-prettier path/to/your/file.js' to check for conflicts. For projects with multiple config files or overrides, provide several file paths to improve detection accuracy.

Question 6

What happens if I use deprecated rules with eslint-config-prettier?

Accepted Answer

eslint-config-prettier may disable deprecated or removed rules by default. If you need to exclude them, set the ESLINT_CONFIG_PRETTIER_NO_DEPRECATED environment variable, as mentioned in the README, but this is usually unnecessary.
