install-prettier

Before proceeding, ensure nvm (Node Version Manager) and Node.js are installed using the install-nodejs skill.

1. •

   Create .prettierrc.json in the project root if it doesn't already exist.

2. •

   The content of .prettierrc.json should at a minimum contain every setting listed below (do not remove any existing setting just ensure these settings all exist and if not add them):

   json

    {
      "printWidth": 120,
      "singleQuote": true,
      "semi": true,
      "tabWidth": 2,
      "trailingComma": "none",
      "endOfLine": "lf"
    }
   

3. •

   Create .prettierignore in the project root if it doesn't already exist.

4. •

   The content of .prettierignore should at a minimum contain every setting listed below (do not remove any existing setting just ensure these settings all exist and if not add them):

   code

   node_modules
   dist
   build
   coverage
   

5. •

   If a package.json file exists in the project root, ensure prettier:fix and prettier:check are listed as scripts command, and if these commands don't exist add them.

   json

    "scripts":{
      "prettier:fix": "npx prettier --fix ."
      "prettier:check": "npx prettier --check ."
    }
   

6. •

   There is no reason to have prettier configuration or dependency (outside of the two prettier:fix and prettier:check script commands) in package.json or any other file. If extra prettier configuration exists in package.json or any other file, remove it to avoid confusion and ensure all configuration is in .prettierrc.json and .prettierignore. This also applies to "nested" package.json files in subdirectories (for example projects that have a client or cdk directory).
