Install the frontend SDK

Published to npm as versioned packages (@mapper-fe/client, @mapper-fe/core, @mapper-fe/upload, @mapper-fe/react). The four packages use fixed versioning — install the same version together. Requires Node 18+ (or Bun) and, for @mapper-fe/react, React ^19.

npm install @mapper-fe/client @mapper-fe/core @mapper-fe/upload @mapper-fe/react

# pnpm / yarn / bun equivalents
pnpm add @mapper-fe/client @mapper-fe/core @mapper-fe/upload @mapper-fe/react
yarn add @mapper-fe/client @mapper-fe/core @mapper-fe/upload @mapper-fe/react
bun add @mapper-fe/client @mapper-fe/core @mapper-fe/upload @mapper-fe/react

Install only what you need: @mapper-fe/client alone for the headless API client, add @mapper-fe/core for mapping ops and workflow state, @mapper-fe/upload for the multipart upload adapter, and @mapper-fe/react for the editor/importer components. For React, also import the stylesheet (CSS variables only, no Tailwind required):

import "@mapper-fe/react/styles.css";

Next: create the client and render the importer as shown in the Frontend SDK guide.
