Add a new Remotion package

Steps

  • Create packages/<name>/ with these files:
  • package.json — copy from @remotion/light-leaks as template; update name, description, homepage, dependencies
  • tsconfig.json — extends ../tsconfig.settings.json, uses tsgo with emitDeclarationOnly: true, outDir: "dist", module: "es2020", moduleResolution: "bundler", target: "ES2022"
  • src/index.ts — exports
  • bundle.ts — Bun build script, externalize react, remotion, remotion/no-react, react/jsx-runtime, react/jsx-dev-runtime, react-dom
  • eslint.config.mjs — use remotionFlatConfig({react: true}) if React, {react: false} otherwise
  • .npmignore — copy from @remotion/light-leaks
  • README.md — package name, description, install command, link to docs
  • Register in monorepo:
  • tsconfig.json (root) — add {"path": "./packages/<name>"} to references
  • packages/cli/src/list-of-remotion-packages.ts — add '@remotion/<name>'
  • packages/create-video/src/list-of-remotion-packages.ts — add '@remotion/<name>'
  • packages/studio-shared/src/package-info.ts — add to packages, descriptions, installableMap, apiDocs
  • Documentation (packages/docs/docs/<name>/):
  • Add "@remotion/<name>": "workspace:*" to packages/docs/package.json dependencies (needed for twoslash snippets)
  • index.mdx — install tabs, table of contents, license
  • table-of-contents.tsx — TOCItem grid linking to component/function pages
  • Individual component/function .mdx pages
  • Edit packages/docs/sidebars.ts — add category
  • Edit packages/docs/components/TableOfContents/api.tsx — import table of contents and add section

See the writing-docs skill for details on writing documentation.

  • Example usage:
  • Add "@remotion/<name>": "workspace:*" to packages/example/package.json
  • Create packages/example/src/<Name>/index.tsx
  • Register <Composition> in packages/example/src/Root.tsx
  • Add {"path": "../<name>"} to packages/example/tsconfig.json references
  • Run bun i to install dependencies
  • Build: cd packages/<name> && bun run make

Version

Use the current version from packages/core/src/version.ts.

For the documentation version, increment the patch version by 1 as it will only be released with the next Remotion release.

Patterns

  • Use "workspace:*" for internal dependencies
  • Use "catalog:" for shared external dependency versions
  • The make script is: tsgo && bun --env-file=../.env.bundle bundle.ts
  • Add "type": "module" to package.json
  • Add "@typescript/native-preview": "catalog:" to devDependencies
  • Types/main point to dist/index.d.ts and dist/index.js (not dist/cjs/)
  • Packages with React components need peerDependencies for react and react-dom

How to use it

Copy the folder

Take remotion-dev/add-new-package from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.
