Install the React SDK
The current package requires React 18 or newer and ships browser ESM, CommonJS,
and TypeScript declarations.
Add a public client key
Create a pub_ key for the environment, then expose only that public key to the
browser:
For Vite or another bundler, read its public environment variable yourself and
pass the string through clientKey.
Never put an sdk_, admin_, or cli_ key in browser code or a public
environment variable.
Mount the provider
In a Next.js App Router project, mount the provider from a client component.
Read flags
Use typed hooks, status, targeting context, and telemetry.
API reference
Review provider props, hooks, state, and cache behavior.
