Feedback Widget for Next.js Applications

Adem IlterAdem IlterDesigner @Upstash

User feedback is important to guide product decisions. We built a widget to help you get feedback from your users. It is a React component which calls Next.js API as its backend. The backend API simply sends the feedback data to Upstash Redis database. Also, you will be able to see and manage the submitted data in Upstash Console Integrations Page

When you add the component to your Next.js page, an icon will be displayed on bottom right corner. When clicked, feedback form will be visible. Check the demo to see how it works.

See the Github repo to check out the code. Currently, the widget is designed to be used in a Next.js application. We welcome your contributions to support others like Nuxt, SvelteKit or Remix

Install dependencies:

npm install @upstash/feedback @upstash/redis

Component and style:

// pages/_app.js
import "@upstash/feedback/style.css";
import FeedbackWidget from "@upstash/feedback";
export default function MyApp({ Component, pageProps }) {
  return (
      <FeedbackWidget type="full" />
      <Component {...pageProps} />

Copy/paste the below API code to pages/api/feedback.js

// pages/api/feedback.js
import { Redis } from "@upstash/redis";
const redis = new Redis({
export default async function FeedbackWidgetAPI(req, res) {
  try {
    await redis.hset("feedback", { [Date.now().toString()]: req.body });
    return res.status(200).json({ message: "success" });
  } catch (err) {
    return res.status(400).json({ message: err });

You need to create a Redis database at Upstash then replace UPSTASH_REDIS_REST_URL and UPSTASH_REDIS_REST_TOKEN which can be found at the database details page in Upstash Console.

Admin Dashboard

Upstash Console has a page under Integrations > Feedback Widget so you can see and manage the submitted feedback.

user : Use user field to pass user's id or email as a parameter, so the user will not have to enter their email.

<FeedbackWidget type="full" user={currentUser.email} />

To allow anonymous submission, set any string as a user id just to hide email input.

<FeedbackWidget type="full" user="anything" />

metadata : You can attach extra information using the metadata field.

showOnInitial : Set true, if you prefer the input dialog to be shown at initial.
