How to add to a new Node.js repository

If you're creating a new repository, you can use the following GitHub template. Otherwise, please follow those steps:

• Add a .eslintrc.cjs file to the root of the project. Individual rules and overrides can be tweaked for the specific project.

// Use '@netlify/eslint-config-node/esm' if the repository is using pure ES modules
const { overrides } = require('@netlify/eslint-config-node')

module.exports = {
  extends: '@netlify/eslint-config-node',
  rules: {},
  overrides: [...overrides],
}

• Add the following .prettierrc.json to the root of the project:

"@netlify/eslint-config-node/.prettierrc.json"

• Copy the commitlint.config.cjs, .editorconfig and .gitattributes files relativity to the root of the project.
• Add the following properties to the package.json. Please replace the config globbing expressions to match the files where the source JavaScript/Markdown/HTML/JSON/YAML files are located. npm run format should also be run during npm test and npm run format:ci during CI (example).
