There is not. payload can be anything by design.
however, if you mean inteliisense for things like node
and javascript
function then use jsdoc to instruct vscode of the type...
/** @type {string} */ var payload = msg.payload */
Ok, so you dont need to run node-red from src.
all you need to do is...
- follow the normal NPM install from node-red docs
- run node-red once (i.e.
node-red
) to generate the flows and settings files - use this guide to run node-red in vscode
