Using Autocomplete in Next.js


Autocomplete is a common feature in modern web applications that enhances user experience by providing suggestions as users type into input fields. Next.js, a popular React framework, makes it easy to implement autocomplete functionality. In this article, we will walk through the steps to add autocomplete to a Next.js application.


Before we begin, make sure you have the following prerequisites in place:

  1. Node.js and npm are installed on your machine.
  2. A basic understanding of Next.js and React.
  3. A Next.js project set up. If you don't have one, you can create a new Next.js application using npx create-next-app.

Step 1. Install Dependencies

First, navigate to your Next.js project directory and install the necessary dependencies.

npm install react-autosuggest

react-autosuggest is a popular library for implementing autocomplete functionality in React applications.

Step 2. Create an Autocomplete Component

In your Next.js project, create a new React component for the autocomplete feature. You can place it in a relevant directory, such as /components.

// components/Autocomplete.js

import React, { Component } from 'react';
import Autosuggest from 'react-autosuggest';

class Autocomplete extends Component {
  constructor() {

    // Initialize state with an empty input value and suggestions array
    this.state = {
      value: '',
      suggestions: [],

  // Define your data source (e.g., an array of suggestions)
  getSuggestions = (value) => {
    // Implement your suggestion logic here
    // This function should return an array of suggestion objects
    // based on the input value.

  // Update the input value as the user types
  onChange = (event, { newValue }) => {
      value: newValue,

  // Triggered when a suggestion is selected
  onSuggestionSelected = (event, { suggestion }) => {
    // Handle the selected suggestion, e.g., update the state or perform an action.

  // Render each suggestion in the suggestion list
  renderSuggestion = (suggestion) => {
    // Customize the appearance of each suggestion item
    // You can return a JSX element here.

  // Render the autocomplete input
  render() {
    const { value, suggestions } = this.state;

    const inputProps = {
      placeholder: 'Type a term...',
      onChange: this.onChange,

    return (
        getSuggestionValue={(suggestion) =>}

export default Autocomplete;

In this component, we've set up the basic structure for the autocomplete functionality. You'll need to implement the getSuggestions, onSuggestionSelected, and renderSuggestion functions according to your application's specific needs.

Step 3. Integrate the Autocomplete Component

Now that you've created the Autocomplete component, you can integrate it into your Next.js application. Import the component and use it within your pages or components.

// pages/index.js (or any other page/component where you want to use autocomplete)

import React from 'react';
import Autocomplete from '../components/Autocomplete';

function Home() {
  return (
      <h1>Autocomplete Example</h1>
      <Autocomplete />

export default Home;

Step 4. Implement getSuggestions Logic

The getSuggestions function in the Autocomplete component should be customized to fetch suggestions based on user input. You can use an API call, search through a local dataset, or implement any other suggestion logic suitable for your application.


Adding autocomplete functionality to your Next.js application can significantly improve the user experience. By following these steps and customizing the Autocomplete component to fit your specific use case, you can enhance the search and input experiences in your web application. Remember to test your implementation thoroughly to ensure it meets your requirements and provides a seamless user experience.
