API endpoint

This tutorial uses the GET v2/feed endpoint
Imagine you want to create a custom list of users in your app and show a feed of casts based on users in the list, similar to Twitter lists.
feed

​
Create a feed given a list of users

In this example, we will try to feed for fids 1, 2 and 3. If you know someone’s username, you can find their fid from our user endpoint.

​
Ensure you have the right environment setup

Make sure to have node.js, typescript (ts) and yarn installed on your machine

​
Create a new typescript file with the right imports

import { NeynarAPIClient, isApiErrorResponse } from "@neynar/nodejs-sdk";
import { AxiosError } from "axios";

import {
  FeedType, FilterType,
} from "@neynar/nodejs-sdk/build/neynar-api/neynar-v2-api";

​
Initialize the client

const client = new NeynarAPIClient("API_KEY");

​
Call fetchFeedPage function to get feed

(async () => {
  try {
    const cast =
      await client.fetchFeedPage(FeedType.Filter, {
        filterType: FilterType.Fids,
        fids: "1,2,3",
        limit: 1, // change to however many casts you want to fetch at once (max 100)
        withRecasts: true,
      });
    console.log(JSON.stringify(cast));
  } catch (error) {
    // isApiErrorResponse can be used to check for Neynar API errors
    // handle errors accordingly
    if (isApiErrorResponse(error)) {
      console.log("API Error", error.response.data);
    } else {
      console.log("Generic Error", error);
    }
  }
})();

​
Run your new .ts file

  • Navigate to the right folder in your terminal e.g. cd ./test-sdk
  • Run script by typing yarn start into the terminal

​
You should now see an output like this

You get all the data in one request, making it easy to display or use in your next operation. If you want to try getting a live response, head over to our API page for v2/feed. You can take the cursor from the output and pass it in the next request to the SDK to page to the next set of results.
