Publish a Algorithm	Tutorial to add Algorithm dataset publishing capabilities to a basic React app.

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 Asset

First, let's add the asset that we want to publish.

To do that, we need to define the Algorithm asset based on the OEP-08 metadata structure. An algorithm asset can have multiple files attached to it and each file's url value will be encrypted during the publish process.

Let's create a new file src/asset-compute.js and fill it with:

GITHUB-EMBED 107d1fa7d0/src/asset-compute.js jsx 1-33 GITHUB-EMBED

** Notice the “ALGO” macro in the entrypoint attribute, this is replaced with the downloaded executable algorithm inside the pod

Then import this asset definition at the top of src/Compute.js:

GITHUB-EMBED 107d1fa7d0/src/Compute.js jsx 4 GITHUB-EMBED

Handle Asset Publishing

Now that we have an asset to submit, we need a function to handle it. Just before render() { let's add this publishalgo function:

GITHUB-EMBED 107d1fa7d0/src/Compute.js jsx 42-56 GITHUB-EMBED

The last thing we need is a button to start our registration inside the render() function:

GITHUB-EMBED 107d1fa7d0/src/Compute.js jsx 153 GITHUB-EMBED

Move on to Compute using a published algorithm on a Data Set.
