Important

This minimal example demonstrates how to build a poll Frame without the use of a framework. If you're looking to build a Frame we recommend using frog or frames.js.

Farcaster Frames Poll app

A example Poll app using Farcaster Frames.

This example lets you create a poll and have users vote on it. The FrameAction is authenticated against a hub so the votes cannot be spoofed (if HUB_URL is provided), and the results are stored in a redis database.

Demo

• https://fc-polls.vercel.app/

Setup

• After deploying your repo to Vercel...
• Create a kv database https://vercel.com/<name>/<project>/stores
• Set the KV prefix url's for the new kv database
• Navigate to env variables: https://vercel.com/gregan/fc-links-vote/settings/environment-variables
• If you're doing something production facing w/ trusted data, set the HUB_URL environment variable to a production hub's public ip address port 2283 ref: https://docs.farcaster.xyz/reference/frames/spec#frame-signature-packet
• Set the HOST env variable to your public facing url or domain, ie; https://<project>.vercel.app/
