Hello Folks ๐Ÿ‘‹

This is Savio here. I'm young dev with an intention to enhance as a successful web developer. I love building web apps with React. I have proved my superiority in frontend technologies.

Today, Let's learn how you can create a well-efficient search filter in React โœŒ๏ธ. So, let's start!

Create React App

First of all, we first have to create a react app. You know it!

npx create-react-app search-filter-app

This will create you a normal react app. You can start the server by npm start. Now, let's have a look at our folder structure ๐Ÿฅ Make sure, you have this files ready ๐Ÿค—

โ”œโ”€โ”€ App.css
โ”œโ”€โ”€ App.js
โ””โ”€โ”€ index.js

Lets start with App.js, we can use API, to get some fake posts data. First, lets create a useState hook ๐Ÿ‘€

const [data, setData] = useState([]);

Now, lets create a useEffect with no dependency that should load only once. ๐Ÿ’ช

useEffect(() => {
      .then((response) => response.json())
      .then((json) => setData(json));
  }, []);

Now, lets render our app, we just need an input that acts as our search bar and then, lets map through the data โœŒ๏ธ

<div className="App">
    <input type="text" placeholder="Search name"  />
    {, key) => {
          return (
            <p className="blog" key={key}>

Now, lets next step is to handle the search, for that, I'm setting a new useState hook called searchTerm ๐Ÿป

const [searchTerm, setSearchTerm] = useState("");

And now, lets handle the onChange event of our input ๐Ÿ‘‡

<input type="text" placeholder="Search name" value={searchTerm} onChange={(e)=> setSearchTerm(}

And lastly, lets create a small logic of handling the search, lets use filter for it, we're first converting it to toLowerCase() and then check if it is same as searchTerm, and then map through it. Lets see how I made it work ๐Ÿ‘‡

    .filter((val) => {
      if (searchTerm === "") {
        return val;
      } else if (
      ) {
        return val;
    .map((post, key) => {
      return ( 
        <p className="blog" key={key}>

that's it ๐ŸŽ‰, you made it work, it works just fine, lets add some css to make it better ๐Ÿ‘‡ Add this to App.css

input {
  padding: 10px;
  border: 1px solid #111;
  width: -webkit-fill-available;
  border-radius: 5px;
.blog {
  padding: 10px;
  border: 1px solid #ccc;
  border-radius: 5px;

Now, everything is over, time to test it, Here it goes, it works like a charm ๐Ÿ’– Congrats ๐Ÿฅณ
