Requirements

This is a continuation of the React App Setup tutorial, so make sure you have done all the steps described in there.

1. React App Setup

Open src/Compute.js from your marketplace/ folder.

Define Compute Output

First, let's define some options for our upcoming job:

GITHUB-EMBED 107d1fa7d0/src/Compute.js jsx 163-182 GITHUB-EMBED

and use them

GITHUB-EMBED 107d1fa7d0/src/Compute.js jsx 61-70 GITHUB-EMBED

Order the dataset

Next, we have to order the dataset that we are going to compute upon. We are going to use the ddoAssetId, which was set during publishing of the asset.

GITHUB-EMBED 107d1fa7d0/src/Compute.js jsx 73 GITHUB-EMBED

Start the compute job

And finally, start the job:

GITHUB-EMBED 107d1fa7d0/src/Compute.js jsx 76-82 GITHUB-EMBED

Final Result

Now that we have all the requirements, we need a function to handle it.

GITHUB-EMBED 107d1fa7d0/src/Compute.js jsx 58-89,92-94 GITHUB-EMBED

The last thing we need is a button to start our compute job:

GITHUB-EMBED 107d1fa7d0/src/Compute.js jsx 202-207 GITHUB-EMBED

** Notice that the button will be disabled if there were no previous published Datasets and Algorithms.
