Pull requests are welcome! Take note of the following guidelines:

• Edit scripts/data.json to add new entries or update existing ones.
  • Do not edit README.md or other markdown files directly.
• Ensure that official names are used with correct spelling, capitalization and styling.
  • For example, use "Node.js" instead of "nodejs" or "node.js". Use "npm" instead of "NPM".
• type field should be a string or an array of strings.
• Add year_created and year_created_source fields.
  • year_created_source should cite npm package version page, GitHub release page, Wikipedia page with first release date information or other official sources which indicate the year of creation or first release.
  • year_created_source_alt can be added to cite an alternative official source, in case the primary source is no longer available.
  • Add year_deprecated and year_deprecated_source fields when applicable.
• Optionally, run npm run generate to update the README.md and other markdown files automatically.
  • To avoid the need to run npm run generate for each change, setup a git pre-commit hook with script below:
  • node scripts/generate.js && git add *.md

• The term is closely related to frontend development and widely known among a group of frontend developers, e.g. webpack, React, Figma.
• The term is not specific to frontend but used extensively by frontend developers, e.g. git, GitHub, Node.js.
