Collaborative Flowchart Builder (Advanced)

You can place blocks, connect them, edit labels, undo and redo, and attach comments to the canvas or to specific blocks.

Getting started

Run the following command to try this example locally:

$npx create-liveblocks-app@latest --example nextjs-flowchart-builder --api-key

This will download the example and ask permission to open your browser, enabling you to automatically get your API key from your liveblocks.io account.

Manual setup

Alternatively, you can set up your project manually:

• Install all dependencies with npm install
• Create an account on liveblocks.io
• Copy your secret key from the dashboard
• Copy .env.example to .env.local and set LIVEBLOCKS_SECRET_KEY
• Run npm run dev and go to http://localhost:3000

Dev server setup

You can optionally run this example locally using the Liveblocks dev server.

• Install the example as detailed above
• Run npx liveblocks dev to start the server
• Replace the secret in new Liveblocks with "sk_localdev"
• Run npm run dev and go to http://localhost:3000

Deploy on Vercel

To both deploy on Vercel, and run the example locally, use the following command:

$npx create-liveblocks-app@latest --example nextjs-flowchart-builder --vercel

This will download the example and ask permission to open your browser, enabling you to deploy to Vercel.

Develop on CodeSandbox

After forking this example on CodeSandbox, create the LIVEBLOCKS_SECRET_KEY environment variable as a secret.
