In this tutorial you will:

Step 1: Setup the Feelback project

If you don't have already a Feelback account, please signup and create one. It's free and doesn't require a credit card to use.

Access the Feelback panel, and create a project if you don't have any. Feelback panel projects

You can use your website name.

After that, create a ContentSet which will contain your content and feedbacks you will receive.

Step 2: Install the Feelback plugin

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

npm install @feelback/react

Step 3: Add the FeelbackTaggedMessage component to the layout page

Now you are ready to add the Send Feedback buttons. Let’s suppose you want place the button on the right sidebar, just below the table of content.

To edit the default theme, in Docusaurus you have to run a procedure called Swizzling which allows to replace a builtin component with a custom one.

Perform the Docusaurus swizzle on the TOC component

We want to wrap the current TOC component and append the Send Feedback button. For the Docusaurus default theme, the component is called: TOCItems

In the your Docusaurus directory run:

npm run swizzle @docusaurus/theme-classic TOCItems --wrap

This will copy the original component to your source folder at src/theme/TOCItems so you can modify it.

Edit the component and add the Feedback button

Now you can wrap the original component and add the button.


import React from 'react';
import TOCItems from '@theme-original/TOCItems';
import { FeelbackTaggedMessage, PRESET_FEEDBACK } from "@feelback/react";

export default function TOCItemsWrapper(props) {
  return (
      <TOCItems {...props} />

      <div className="feelback-toc" style={{ padding: "0 16px" }}>
        <FeelbackTaggedMessage contentSetId="your-content-set-id-from-panel"

Include the default Feelback style

Append the default style provided by the package at the end of your custom.css file.

@import "@feelback/react/styles/feelback.css";

The result should be something like this:

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.
