Watching code run: jadpo watch

On this page

Your agent can wait for one part of the code to run and then see its inputs and outputs, without reading whole logs.

What you can watch

You name the code as the compiler knows it: a route, action, query, subscriber, schedule, provider operation, domain or file. Add --failed or --faulted to see only the runs that failed or faulted. A name the compiler doesn't know is an error that names the nearest match, as everywhere else in Jadpo.

What each match prints

Each match prints the step that ran: its inputs, its output or failure, the queries, writes, events and calls inside it, its timings, and the request id, so jadpo trace <request id> opens the whole request.

For an action with several changing calls, each step shows its state. A step that didn't finish is an item for an operator, the person running the app, to resolve (What an operator sees).

Waiting for one run

--once exits after the first match. Your agent starts the command in the background, triggers the flow, and waits for the command to finish rather than polling. --count <n> and --timeout <duration> limit how long it waits, and --json gives the same output as data.

Values in full, in development only

jadpo watch works only in development. It shows values in full, as the development call log shows what was sent to providers, read from data that jadpo dev keeps out of git. Secrets are never shown. In production, only the spans are kept, with no values (Telemetry).
