title: Compute using a raw algorithm on a Data Set
|

description: Compute using a raw algorithm on a Data Set
|
|

|
|
|
|
## Requirements
|
|
|
|
This is a continuation of the [React App Setup](/tutorials/react-setup/) tutorial, so make sure you have done all the steps described in there.
|
|
|
|
1. [React App Setup](/tutorials/react-setup/)
|
|
|
|
Open `src/Compute.js` from your `marketplace/` folder.
|
|
|
|
## Define Raw Code
|
|
|
|
Sometime, you just need to quickly run an test algorithm. Instead of publishing it as an asset, you can use the code directly.
|
|
|
|
To do that, we are going to use a textbox for copy/paste and a button to show/hide it.

|
|
|
|
## Define Algorithm MetaData
|
|
|
|
We need to define all the requirments for the algorithm:
|
|
|
|
GITHUB-EMBED https://github.com/oceanprotocol/react-tutorial/blob/107d1fa7d0c583cc8042339f1f5090ff9ee0920b/src/asset-compute.js jsx 35-44 GITHUB-EMBED
|
|
|
|
and them import it to our Compute.js:
|
|
|
|
GITHUB-EMBED https://github.com/oceanprotocol/react-tutorial/blob/107d1fa7d0c583cc8042339f1f5090ff9ee0920b/src/Compute.js jsx 4 GITHUB-EMBED
|
|
|
|
|
|
## Define Compute Output
|
|
|
|
Let's define some options for our upcoming job:
|
|
|
|
GITHUB-EMBED https://github.com/oceanprotocol/react-tutorial/blob/107d1fa7d0c583cc8042339f1f5090ff9ee0920b/src/Compute.js jsx 163-182 GITHUB-EMBED
|
|
|
|
and use them
|
|
|
|
GITHUB-EMBED https://github.com/oceanprotocol/react-tutorial/blob/107d1fa7d0c583cc8042339f1f5090ff9ee0920b/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 https://github.com/oceanprotocol/react-tutorial/blob/107d1fa7d0c583cc8042339f1f5090ff9ee0920b/src/Compute.js jsx 73 GITHUB-EMBED
|
|
|
|
## Start the compute job
|
|
|
|
We need a function to start the job:
|
|
|
|
GITHUB-EMBED https://github.com/oceanprotocol/react-tutorial/blob/107d1fa7d0c583cc8042339f1f5090ff9ee0920b/src/Compute.js jsx 58-89 GITHUB-EMBED
|
|
|
|
Get the pasted code:
|
|
|
|
GITHUB-EMBED https://github.com/oceanprotocol/react-tutorial/blob/107d1fa7d0c583cc8042339f1f5090ff9ee0920b/src/Compute.js jsx 96-100 GITHUB-EMBED
|
|
|
|
The last thing we need is a button inside the `render()` function:
|
|
|
|
GITHUB-EMBED https://github.com/oceanprotocol/react-tutorial/blob/107d1fa7d0c583cc8042339f1f5090ff9ee0920b/src/Compute.js jsx 208-211 GITHUB-EMBED
|
|
|
|
** Notice that the button will be disabled if there were no previous published Datasets.
|
|
|
|
**Move on to [Get Status of a Compute Job](react-compute-status).**
