Debug
The pipeline equivalent of a print statement. Attach it to any output to see exactly what that node produced.
Type: debug · Category: Output · Ports: one input · no output
When to use it
- While building anything — it is the fastest way to see a real payload
- Confirming the shape of a message before writing the node that consumes it
Settings
| Setting | Key | Default | Purpose |
|---|---|---|---|
| Display mode | displayMode | full | The whole message, or just the payload. |
Gotchas
- Take it off high-rate branches before production. A Debug node on a subscription firing 50 times a second is doing 50 serialisations a second and pushing all of it to every open browser.
