Hello Folks 👋
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, I'm super pumped to build an amazing Image search app using Unsplash API with infinite scrolling. So, let's get started ✌

Setting up Unsplash API
-
To set up Unsplash API for your app, head over to https://unsplash.com/developers and create an account 👤
-
After creating an account, go to your apps section. Here you could see your app. Now, create a new app by clicking New Application button.
-
Now accept all terms, this would create an app for you
-
You will be redirected to your app, here when you scroll you can see a section called Keys 🔑. Here you can see your access key, just save it for later. We are gonna use this.
Let's Start Coding
So, it is time to get into coding our app. So, take your coffee and start coding! ⚡ First of all, let's create a react app by copy-pasting this code in the terminal.
npx create-react-app unsplash-image-search
Getting Into the project directory
cd unsplash-image-search/
Here are the dependencies that we use for our project 👩💻
View Website

- Axios
- react-infinite-scroll-component
Let's install all the dependencies using NPM.
npm i axios react-infinite-scroll-component
Starting our server ✨
npm start
Now we can see our app running in localhost:3000
Now, we can clear some unwanted files in our src/ folder. (this is optional). I am removing all the files except App.js, index.js and index.css. I am also clearing the default code.
So, let's first start with App.js.
We can create 2 variables, this would help in fetching images using Unsplash API 📸
const client_id = "YOUR_ACCESS_KEY";
const fetchUrl = `https://api.unsplash.com/search/photos?client_id=${client_id}&query=${query}&page=${page}`;
and next we're setting some useState hooks.
const [data, setData] = useState([]);
const [query, setQuery] = useState("code");
const [page, setPage] = useState(1);
const [hasMore, setHasMore] = useState(true);
Now, create a function to fetch Images through Unsplash API. We are also gonna use axios that make the work faster. We are also increasing the page number after a load setPage(page + 1), this act important for infinite scrolling. Here goes the desired function 👇
const fetchImages = () => {
axios
.get(fetchUrl, {
headers: {},
})
.then((response) => {
setData([...data, ...response.data.results]);
})
.catch((error) => {
console.log(error);
});
setPage(page + 1);
};
Now, lets create a useEffect hook that would run whenever query is changed. Here goes the code 👇
useEffect(() => {
fetchImages();
}, [query]);
Now, lets return all our components. It consists of a input and the InfiniteScroll wrapper. Inside InfiniteScroll wrapper, we map all images. 📷
return (
<div className="App flex">
<input
type="text"
onKeyDown={(e) => searchImages(e)}
placeholder="Search For Images 🔎"
/>
<InfiniteScroll
dataLength={data.length}
next={fetchImages}
hasMore={hasMore}
loader={<p>Load more...</p>}
endMessage={
<p style={{ textAlign: "center" }}>
<b>Yay! You have seen it all</b>
</p>
}
>
<div className="main flex">
{data.map((data, key) => (
<div className="container" key={key}>
<img
src={data.urls.small}
className="image"
alt={data.alt_description}
/>
<h4>Photo by {data.user.name} 📸</h4>
</div>
))}
</div>
</InfiniteScroll>
</div>
);
We also want to update our query on every enter click on the input. For that we're gonna use a new function.
const searchImages = (e) => {
if (e.keyCode === 13) {
setQuery(e.target.value);
setData([]);
}
};
So, the work of App.js is finished. Here goes the complete code 👇
App.js
import axios from "axios";
import { useEffect, useState } from "react";
import InfiniteScroll from "react-infinite-scroll-component";
import "./App.css";
function App() {
const [data, setData] = useState([]);
const [query, setQuery] = useState("code");
const [page, setPage] = useState(1);
const [hasMore, setHasMore] = useState(true);
const client_id = "4mB0CC1xdwTfTQGjF1v1uO9vS2Z8ubzBPd4X0B86IEU";
const fetchUrl = `https://api.unsplash.com/search/photos?client_id=${client_id}&query=${query}&page=${page}`;
const fetchImages = () => {
axios
.get(fetchUrl, {
headers: {},
})
.then((response) => {
setData([...data, ...response.data.results]);
})
.catch((error) => {
console.log(error);
});
setPage(page + 1);
};
const searchImages = (e) => {
if (e.keyCode === 13) {
setQuery(e.target.value);
setData([]);
}
};
useEffect(() => {
fetchImages();
}, [query]);
return (
<div className="App flex">
<input
type="text"
onKeyDown={(e) => searchImages(e)}
placeholder="Search For Images 🔎"
/>
<InfiniteScroll
dataLength={data.length}
next={fetchImages}
hasMore={hasMore}
loader={<p>Load more...</p>}
endMessage={
<p style={{ textAlign: "center" }}>
<b>Yay! You have seen it all</b>
</p>
}
>
<div className="main flex">
{data.map((data, key) => (
<div className="container" key={key}>
<img
src={data.urls.small}
className="image"
alt={data.alt_description}
/>
<h4>Photo by {data.user.name} 📸</h4>
</div>
))}
</div>
</InfiniteScroll>
</div>
);
}
export default App;
Now, our app is working but our app lacks beauty. So, lets style our app 🎨.
App.css
@import url(https://fonts.googleapis.com/css?family=Poppins:100,100italic,200,200italic,300,300italic,regular,italic,500,500italic,600,600italic,700,700italic,800,800italic,900,900italic);
* {
margin: 0;
padding: 0;
font-family: "Poppins", sans-serif;
}
body {
background: #f5effc;
}
.App {
flex-direction: column;
}
.image {
width: 363px;
border-radius: 5px;
height: 240px;
}
.container {
border-radius: 5px;
margin: 5px;
padding: 15px;
box-shadow: 0 10px 40px -10px rgb(0 64 128 / 10%);
border: 1px solid #eee;
background: #f9fafc;
}
h4 {
font-weight: 400;
}
.flex {
display: flex;
align-items: center;
justify-content: center;
}
.main {
width: 100%;
height: 100%;
flex-wrap: wrap;
}
input {
padding: 10px;
box-shadow: 0 10px 40px -10px rgb(0 64 128 / 10%);
border: 1px solid #ddd;
background: #f9fafc;
width: 40%;
margin: 15px 0;
}
Congrats 🎉, You have now finished working on our app. Our app is now working perfectly as expected. You did it, it was so fast! Our app now looks like this 👇
