How to Fetch Data from Third-Party Services

Sometimes we need our blocks to consume third-party data, such as a blog API. In this how-to, we will see how to achieve just that.

We will be consuming data from https://jsonplaceholder.typicode.com/posts.

1. Locate Your Get Data File

Open up your block's code and find getDataProps.js. It should look like this:

export const getDataProps = (utils, props) => Promise.resolve()

2. Make the Request Call You Need

export const getDataProps = (utils, props) => {
 return utils.client
 .request('https://jsonplaceholder.typicode.com/posts')
 .then(res => res.json())
 .catch(e => [])
}

The request function is exactly like the fetch function, and works both in the server and on the client. You don't have to care about importing the right version of the function depending on which environment you are in.

3. Use the Data from Your Block

From your render function located in src/Block.js, you will have the data available:

function StarterBlock(props) {
 const posts = props.data;
  ...
}
