CopilotKit v2 Express Example (Single Route)

This example hosts a CopilotKit v2 runtime using Express and the single-route helper.

Setup

pnpm -C ../../ install

Create a local env file:

cp .env.example .env

Set OPENAI_API_KEY in .env.

Run

pnpm -C ../../ --filter node-express example-dev

The runtime will be available at:

http://localhost:4000/api/copilotkit

Build

pnpm -C ../../ --filter node-express example-build

Notes

• This example uses createCopilotEndpointSingleRouteExpress.
• TypeScript uses moduleResolution: node16 to resolve the @copilotkit/runtime/express export correctly.
