⚡️ Replaying flows

Easily reproduce flows in your application by using Helios' built-in flow replay code generation functionality.

Triggers in Helios enable users to reproduce specific flows fast. The trigger is essentially the root span of the trace, and can often be generated from a specific trace to reproduce that flow again.


Generating a trigger in Helios

In addition, through the trace visualization it is possible to generate the trigger for specific spans inside the trace itself. This functionality is accessible directly from each applicable span.

Traces resulting from triggers generated in Helios are indicated as such using the Helios watermark.

Editing trigger code

Once the trigger code is generated, users can easily edit its configuration. Values can be updated inline directly, or alternatively variables may be used.


Editing the trigger code directly in Helios

Editing triggers on the fly can be particularly useful when trying to test quickly how different parameters impact the flow at hand.

Generating trigger code

Generating trigger code is supported in Node.js and Python. Users can then quickly copy the generated code and use it to reproduce the flow.

Generating a cURL command

Triggers can also be generated as a cURL command. Users may then quickly copy the output and run it to reproduce the flow.

Generating a Postman file

Users can retrieve the trigger code in a file ready to be uploaded into Postman. There it can be easily executed and added to existing trigger collections.

(BETA) Running a trigger in Helios

You may choose to reproduce a flow by running the trigger directly in Helios. Once the flow execution is complete you will be automatically directed to the resulting trace visualization.

Running a trigger in Helios requires a one-time installation of Helios CLI - and afterwards no manual action is required when reproducing a flow.
