How to create a Filter/Search List in React (2022)

Last updated on January 3, 2022 A Goodman Loading... 7 comments

This article walks you through a complete example of making a filter (searchable) list in React. We’ll use the most recent stable version of React (17.0.2) as well as use functional components and hooks.

The Example

Let’s say we have a list of users. Our job is to filter (search) some users by their names.

We’ll use the filter() and startsWith() methods (just two Javascript methods) to find out users whose names match the text entered in the search box. We also use the toLowerCase() method to make it case insensitive.

When the search box is empty, all users will be displayed.


Javascript code

Here’s the full source code in src/App.js:

import React, { useState } from 'react';

import './App.css';

// This holds a list of some fiction people
// Some  have the same name but different age and id
const USERS = [
  { id: 1, name: 'Andy', age: 32 },
  { id: 2, name: 'Bob', age: 30 },
  { id: 3, name: 'Tom Hulk', age: 40 },
  { id: 4, name: 'Tom Hank', age: 50 },
  { id: 5, name: 'Audra', age: 30 },
  { id: 6, name: 'Anna', age: 68 },
  { id: 7, name: 'Tom', age: 34 },
  { id: 8, name: 'Tom Riddle', age: 28 },
  { id: 9, name: 'Bolo', age: 23 },

function App() {
  // the value of the search field 
  const [name, setName] = useState('');

  // the search result
  const [foundUsers, setFoundUsers] = useState(USERS);

  const filter = (e) => {
    const keyword =;

    if (keyword !== '') {
      const results = USERS.filter((user) => {
        // Use the toLowerCase() method to make it case-insensitive
    } else {
      // If the text field is empty, show all users


  return (
    <div className="container">

      <div className="user-list">
        {foundUsers && foundUsers.length > 0 ? (
 => (
            <li key={} className="user">
              <span className="user-id">{}</span>
              <span className="user-name">{}</span>
              <span className="user-age">{user.age} year old</span>
        ) : (
          <h1>No results found!</h1>

export default App;

CSS code

Below’s the full source code in src/App.css:

.container {
  padding-top: 30px;
  width: 300px;
  margin: auto;

.input {
  padding: 5px 15px;
  width: 300px;

.user-list {
  margin-top: 30px;

.user {
  list-style: none;
  margin: 10px 0;
  padding: 10px;
  background: #eee;
  display: flex;
  justify-content: space-between;

.user-id {
  color: red;
  margin-right: 20px;

.user-name {
  color: blue;

.user-age {
  margin-left: auto;

Thank you so much for the example. It helped me solve the filter search challenge I was having.

i want to change the code to search for streetname. However, seems the code is not working. Can you have a look ?

I think we should improve this by using useEffect so it can search from any alphabet that those names have and render the names from the array objects
