  • Notes
  • Configuration

Prerequisites

To use this VSCode extension for formatting JavaScript and TypeScript with prettier-eslint, ensure the following packages are installed, locally:

  • prettier@^3
  • eslint@^8
  • prettier-eslint@^16
  • @typescript-eslint/parser@^6 and typescript@^5 (Only for TypeScript projects)

Notes

The Prettier extension and the ESLint extension are not required, but having the ESLint extension is recommended to display lint errors while editing.

Install Dependencies

Install prettier, eslint and prettier-eslint as dev dependencies in your project. Use the appropriate command based on your project requirements. The commands below use pnpm but you can also use npm. Replace pnpm add with npm i if needed.

Minimum Requirements

pnpm add -D prettier@^3 eslint@^8 prettier-eslint@^16

TypeScript Projects

pnpm add -D prettier@3 eslint@^8 prettier-eslint@^16 @typescript-eslint/parser@^6 typescript@^5

Project Settings

Configure your project by creating or updating a settings.json file at the project's root. If you already have a .vscode/settings.json file, skip the first two steps.

  1. Open the command palette in VSCode:

    • CTRL + SHIFT + P (Windows)
    • CMD + SHIFT + P (Mac OS)
  2. Type Preferences: Open Workspace Settings (JSON).

  3. In the .vscode/settings.json file, copy and paste the following settings:

    {
      "editor.defaultFormatter": "exceptionptr.vscode-prettier-eslint",
      "editor.formatOnType": false, // required
      "editor.formatOnPaste": true, // optional
      "editor.formatOnSave": true, // optional
      "editor.formatOnSaveMode": "file", // required to format on save
      "files.autoSave": "onFocusChange", // optional but recommended
    }
    
  4. Restart VS Code

Your project is now set up to automatically format code upon saving.

Configuration

The extension uses ESLint and Prettier configuration files. These files are resolved from the file being formatted, searching up the file tree.

ESLint Configuration File

Refer to ESLint configuration Use .eslintrc.* or an eslintConfig field in package.json.

Prettier Configuration File

Refer to Prettier configuration

  • prettier field in package.json
  • .prettierrc file (JSON or YAML)
  • .prettierrc.js or .prettier.config.js file
  • .prettierrc.toml file
