A fast and easy REST-like interface to work with Farcaster Hubs. Designed to work with Hubble and any other Hub that implements the Farcaster protocol.
- Call any endpoint using a simple HTTP API, including from a browser environment
- Responses are plain JSON
- Written entirely in Typescript, with strict types for safety.
The examples in this package use axios to make HTTP requests, but you can use any library. It is also useful to install the @farcaster/core library which has several helper methods that are useful while working with Farcaster messages.
yarn add axios @farcaster/core
yarn add -D @types/axios The HTTP API endpoints are documented here.
import axios from "axios";
const fid = 2;
const server = "http://nemes.farcaster.xyz:2281";
try {
const response = await axios.get(`${server}/v1/castsByFid?fid=${fid}`);
console.log(`API Returned HTTP status ${response.status}`);
console.log(`The first cast's text is ${response.messages[0].data.castAddBody.text}`);
} catch (e) {
// Handle errors
console.log(response);
}const getFnameFromFid = async (
fid: number,
client: HubRpcClient
): HubAsyncResult<string> => {
const result = await client.getUserData({
fid: fid,
userDataType: UserDataType.FNAME,
});
return result.map((message) => {
if (isUserDataAddMessage(message)) {
return message.data.userDataBody.value;
} else {
return '';
}
});
};There are several examples in the examples/ folder. To run the examples, please look at the individual README files in the examples directory. Most examples can be run by
yarn install
yarn startgrpc-web was an older way of proxying to the grpc API from web environments. This has been deprecated and is no longer supported. You can read the original grpc-web documentation and examples here.
