Playground

The jam-nodes Playground provides two ways to test nodes interactively:

When to Use Each

Use Case	CLI	Web
Testing nodes during development	Best	Good
Exploring node inputs/outputs	Good	Best
CI/CD or scripted testing	Best	-
Demos and presentations	-	Best
Learning the node API	Good	Best

npm install -g @jam-nodes/playground

npx @jam-nodes/playground list

git clone https://github.com/wespreadjam/jam-nodes
cd jam-nodes/packages/playground-web
npm install && npm run dev

List all available nodes:

jam list

Run a node with mock data (no API keys needed):

jam run delay --mock

Run a node with JSON input:

jam run conditional -i '{"condition":{"type":"equals","variableName":"x","value":"y"},"trueNodeId":"a","falseNodeId":"b"}'

Both CLI and Web interfaces support three credential sources:

Use jam init to generate an .env template with all supported credentials.
