@lomray/prettier-config

Lomray's shared Prettier 3 configuration: 100-column lines, single quotes, semicolons, trailing commas and JSX closing brackets on a separate line.

Install

npm install --save-dev prettier@^3.9.6 @lomray/prettier-config

Add this to package.json:

{
  "prettier": "@lomray/prettier-config"
}

To override individual options, use .prettierrc.mjs:

import config from '@lomray/prettier-config';

export default {
    ...config,
    printWidth: 120,
};

Requires Node ^22.13.0 || >=24 and Prettier 3.9.6+. It does not depend on ESLint. Existing formatting options are unchanged.

Migrate from v2

Upgrade Node and Prettier to the versions above. Older Prettier loaders can ignore an ESM shared config loaded through package.json on recent Node versions. The current toolchain loads both documented configuration forms correctly. No option changes are required.

Develop

Use the Node version in .nvmrc, then run npm ci, npm test, npm run test:packed and npm audit. CI checks Node 22 and 24.
