Why does Prettier not format code in VS Code?

ghz 8months ago ⋅ 90 views

In my Nuxt application where ESlint and Prettier are installed and enabled, I switched to Visual Studio Code.

When I open a .vue file and press CMD+ Shift + P and choose Format Document, my file does not get formatted at all.

My .prettierrc settings:

{
  "tabWidth": 2,
  "semi": false,
  "singleQuote": true
}

I have so many source code lines, so I cannot format them manually. What am I doing wrong?

If the Format Document command is not formatting your Vue.js files in Visual Studio Code, there could be several reasons for this behavior. Here are some troubleshooting steps you can try:

  1. Check File Association: Ensure that Visual Studio Code recognizes .vue files as Vue.js files. You can check this by opening a .vue file and verifying that "Vue" appears in the bottom-right corner of the editor window. If not, you may need to associate .vue files with the Vue.js language mode. You can do this by clicking on the language mode indicator and selecting "Vue" from the list.

  2. Check ESLint and Prettier Integration: Ensure that ESLint and Prettier are properly integrated with Visual Studio Code. You can do this by checking the extensions installed in Visual Studio Code. Search for "ESLint" and "Prettier" in the Extensions view (Ctrl+Shift+X) and verify that they are installed and enabled.

  3. Check ESLint and Prettier Configuration: Make sure that your ESLint and Prettier configurations are compatible and not conflicting with each other. Check the ESLint and Prettier settings in your package.json file, .eslintrc file, and .prettierrc file to ensure they are configured correctly.

  4. Check VS Code Settings: Verify that your Visual Studio Code settings are configured to format Vue.js files using ESLint and Prettier. Open your User or Workspace Settings (File > Preferences > Settings) and search for "format on save" and ensure it is enabled. Also, check the "eslint" and "prettier" sections in your settings to ensure they are configured correctly.

  5. Check ESLint and Prettier Extensions: If you're using ESLint and Prettier extensions in Visual Studio Code, ensure that their settings are configured properly. Open the settings for each extension and verify that they are enabled and configured correctly.

  6. Restart Visual Studio Code: Sometimes, restarting Visual Studio Code can resolve issues with formatting not working properly. Try restarting the editor after making any changes to your settings or extensions.

If you've tried these troubleshooting steps and are still experiencing issues with formatting Vue.js files in Visual Studio Code, you may need to further investigate potential conflicts or configuration errors in your setup.
