About this project
This demo shows you how to implement a multiplayer workflow builder for Jev with Liveblocks. Wire together Jev and LLMs, use the REST API to call the workflow, preview test runs, see multiplayer state and cursors. Install all dependencies with npm install. Copy your secret key from the dashboard. Create an .env file at the root and add your secret key as the LIVEBLOCKSSECRETKEY environment variable. Copy your API key from the console into the TYPESAFEAPIKEY environment variable.

Highlights
- Uses Liveblocks for multiplayer state and cursors, so several people can edit the same Jev workflow graph at once.
- Workflows mix Jev steps with LLM steps and can be invoked through a REST API, with test-run previews in the UI.
- Setup needs three keys: LIVEBLOCKS_SECRET_KEY, TYPESAFE_API_KEY, and AI_GATEWAY_API_KEY, then npm run dev on port 3000.
- Installs with npm install and runs as a Next.js app at localhost:3000.
Quickstart
bash
npm install
npm run devWatch out
No license file, so reuse terms are unclear. Needs a Liveblocks account, a TypeSafe key, and a Vercel AI Gateway key, and it is a demo rather than a packaged tool.
Questions about this entry
Short answers drawn from the linked project or page.
Three keys: a Liveblocks secret key, a TypeSafe API key and a Vercel AI Gateway key, all placed in a .env file at the repo root, then npm install and npm run dev on localhost:3000. Each one is a separate signup in a separate console.
A demo. The README describes wiring Jev and LLM steps into a graph, calling the workflow through a REST API, and previewing test runs, with Liveblocks providing shared state and cursors. No packaged API or CLI surface is described, and the repo has no license file, so reuse terms are unclear.
Not documented beyond one line. The README says you can preview test runs and invoke the workflow over REST, and says nothing about isolation, timeouts, how runs are stored, or whether a preview spends Jev calls, so you would be reading the code to find out.
Yes. Liveblocks supplies the multiplayer state and cursors, so several people edit one Jev workflow graph together in the browser, inside a Next.js app served on port 3000 after npm install.
Run `npm install`, then create accounts for Liveblocks, TypeSafe and Vercel and put their keys in a root .env: LIVEBLOCKS_SECRET_KEY from the Liveblocks dashboard, TYPESAFE_API_KEY from the TypeSafe console, and AI_GATEWAY_API_KEY from the Vercel AI Gateway. Then `npm run dev` and open http://localhost:3000.
It shows how to implement a multiplayer workflow builder for Jev with Liveblocks: wire Jev and LLMs together into a graph, call the workflow through the REST API, preview test runs, and see multiplayer state and cursors.
It is presented as a demo showing how to implement the pattern, built on Liveblocks. It is not packaged as a library or a hosted product, and it depends on Liveblocks plus TypeSafe and Vercel credentials to run.
