Pipedream makes it easy to build event-driven workflows with managed auth (just connect your account and reference tokens and keys in code!). Data is passed between steps in a workflow usingstep exports, which can be inspected and referenced by later steps. In this post, I'll explain how to export data from a loop:

There are two ways to export data from a loop in a Node.js code step on Pipedream:

1. Use a step export array
2. Return an array object after the loop is complete

Use a step export array

To export data from a loop using step exports:

1. Define a step export as an array
2. Add the data you want to export for each loop execution to that array
3. Export the array

this.testExport = []for (let i=0; i < 5; i++) {  this.testExport.push(i)}

When your workflow executes, the step will export an array atsteps.STEP_NAME.testExport with a length of5 and values from0 -4.

Copy and run this workflow to test it out. On each loop execution, the code makes an Axios request to theStar Wars API, and it assigns the response data tosteps.example.testExport:

Return an array object after the loop is complete

To return an array after the loop is complete:

1. Define an array
2. Add the data you want to export for each loop execution to that array
3. Return the array

data = []for (let i=0; i < 5; i++) {  data.push(i)}return i

When your workflow executes, the step will export an array atsteps.STEP_NAME.$return_value with a length of5 and values from0 -4.

Copy and run this workflow to test it out. On each loop execution, the code makes an Axios request to theStar Wars API, and it assigns the response data tosteps.example.$return_value:
