In this tutorial you will:

Step 1: Setup the Feelback project

Step 2: Install the Feelback plugin

In your Nextra project directory, just install the @feelback/react package:

npm install @feelback/react

Step 3: Add the FeelbackTaggedMessage component to the theme config

Now you are ready to add the evaluation form. Let’s suppose you want place it after the article itself, just before the footer.

To edit the docs theme nextra-theme-docs, in Nextra you should modify theme.config.tsx file. We can yse the main extension point to display the feedback form:


import { DocsThemeConfig } from "nextra-theme-docs";

// import the components
import { FeelbackTaggedMessage, PRESET_FEELING } from "@feelback/react";
// include the default style
import "@feelback/react/styles/feelback.css";

export default {
    logo: <span>My Nextra Documentation</span>,
    project: { link: "" },
    feedback: { content: null },
    main: ({ children }) => {
        return (
                <hr />
                <FeelbackTaggedMessage contentSetId="your-content-set-id"
                    title="Did you find this page useful?"
} as DocsThemeConfig

The result should be something like this:

Nextra article footer with evaluation form

Additional documentation with all properties and customization you can use is available inside the dedicated React integration guide for each Feelback components.

Step 4: (Optional) Customize the component style

You can override the predefined style with additional CSS.

For example, you can add some selector to change the button background and have a rounded textarea.


article .feelback-container {
  background-color: #1a8870;
  color: white;

article .feelback-container textarea {
  border: 1px solid #ccc;
  border-radius: 4px;
  padding: 0.5rem;

Full documentation with advanced customization is available inside the React integration guide.
