frames.js
frames.js is the fastest way to make Frames.
What's in frames.js?
- ⚡️ Local frames debugger
- 🥳 Write Frames using React
- 🔋 Batteries included framework
- 🌴 Tree-shakeable & Lightweight
- 🚀 Library with all the functions
Quickstart
Bootstrap the project from template using the CLI tool
Run one of the commands below based on your preferred package manager and then follow the steps in the terminal.
npm init frames@latest
Alternatively, add frames.js to your existing project manually
Start with frames.js in Next.js in three steps
Add frames.js
to your project
yarn add frames.js
Create your Frames app
Create a frames
directory in your Next.js app and add the following files:
import { createFrames } from "frames.js/next";
export const frames = createFrames({
basePath: "/frames",
});
Create a Frames route
/* eslint-disable react/jsx-key */
import { Button } from "frames.js/next";
import { frames } from "./frames";
const handleRequest = frames(async (ctx) => {
return {
image: (
<span>
{ctx.pressedButton
? `I clicked ${ctx.searchParams.value}`
: `Click some button`}
</span>
),
buttons: [
<Button action="post" target={{ query: { value: "Yes" } }}>
Say Yes
</Button>,
<Button action="post" target={{ query: { value: "No" } }}>
Say No
</Button>,
],
};
});
export const GET = handleRequest;
export const POST = handleRequest;
Include Frames alongside your existing page's metadata
import { fetchMetadata } from "frames.js/next";
export async function generateMetadata() {
return {
title: "My Page",
// ...
other: {
// ...
...(await fetchMetadata(
// provide a full URL to your /frames endpoint
new URL(
"/frames",
process.env.VERCEL_URL
? `https://${process.env.VERCEL_URL}`
: "http://localhost:3000"
)
)),
},
};
}
export default function Page() {
return <span>My existing page</span>;
}
Run yarn run dev
This will start the development server but when you open the browser you won't see anything except My existing page
. This is because frames are defined as meta tags therefore you need to use some sort of a client that renders them.
Have fun! 🎉

Local fully interactive Debugger & Frame validation
Or use the hosted Frames debugger. Running locally has the benefits of it working with natively with localhost.
Prefer to not use JSX?
frames.js in Next.js using helper functions
// Page that returns a frame
import { Frame, getFrameFlattened } from "frames.js";
import type { Metadata } from "next";
// Declare the frame
const initialFrame: Frame = {
image: "https://picsum.photos/seed/frames.js/1146/600",
version: "vNext",
buttons: [
{
label: "Random image",
},
],
postUrl: `${process.env.NEXT_PUBLIC_HOST}/frames`,
};
// Export Next.js metadata
export const metadata: Metadata = {
title: "Random Image Frame",
description: "This is an example of a simple frame using frames.js",
openGraph: {
images: [
{
url: "https://picsum.photos/seed/frames.js/600",
},
],
},
other: getFrameFlattened(initialFrame),
};
// Route that handles frame actions
import { getFrameHtml, validateFrameMessage } from "frames.js";
import { NextRequest } from "next/server";
export async function POST(request: NextRequest) {
const body = await request.json();
// Parse and validate the frame message
const { isValid, message } = await validateFrameMessage(body);
if (!isValid || !message) {
return new Response("Invalid message", { status: 400 });
}
const randomInt = Math.floor(Math.random() * 100);
const imageUrlBase = `https://picsum.photos/seed/${randomInt}`;
// Use the frame message to build the frame
const frame = {
version: "vNext",
image: `${imageUrlBase}/1146/600`,
buttons: [
{
label: `Next (pressed by ${message.data.fid})`,
},
],
ogImage: `${imageUrlBase}/600`,
postUrl: `${process.env.NEXT_PUBLIC_HOST}/frames`,
};
// Return the frame as HTML
const html = getFrameHtml(frame);
return new Response(html, {
headers: {
"Content-Type": "text/html",
},
status: 200,
});
}
