How to Use React Icons

Get started with React icons in your project with our practical tutorial. Enhance your application design and user experience with just a few steps.

Using icons in a web project can improve the visual message. For React projects, we have pools of free icon libraries available. But, in this lesson, we’ll look at a library called “React Icons.”

What is React Icons Library?

This small library lets us include icons in our React project from various popular icon sets as React SVG components. These popular icon sets include Font Awesome, Ionicons, Bootstrap icons, Feather, etc.

Using React icons library is a good choice because SVGs:

  1. are supported by all major browsers
  2. take less space compared to other image formats
  3. allows us to style icons without a quality loss

Installing React Icons

Let’s add the React icons via npm like so:

npm install react-icons

Searching for Icons

If we go to the react-icons website, we’ll see all the icons available. On the left panel, we can click on the available fonts library and search for the icons we want. We can go through the list or use CTRL + F or CMD + F to search for specific icons.

Another way to search for icons is to use the search field. We can determine which of the libraries an icon belongs to by looking at the prefix, i.e., the first two letters of the icon name. We’ll use this prefix when importing the icon into our React project.


Adding a Delete, Edit, and Submit Icons

In our todos project, we’ll add FaTrash, AiFillEdit, and FaPlusCircle icons to replace the delete, edit and submit texts, respectively.

Since React icons export icons as React components, we’ll use the ES6 import to include them in our project.

Adding a Submit Icon

We’ll use the FaPlusCircle icon to replace the “Submit” text in the components/InputTodo.jsx file. Let’s open the file and import the SVG component:

import { FaPlusCircle } from "react-icons/fa"

After that, find the following line:

<button className="input-submit">Submit</button>

And replace the text with the icon component element:

<button className="input-submit">
  <FaPlusCircle />

We should see a submit icon in the frontend if we save the file.

The code is self-explanatory. We only imported an icon from the “Font Awesome” icon set and rendered the icon in the JSX.

Adding the Delete and Edit Icons

We’ll use FaTrash and AiFillEdit icons to replace the “Delete” and “Edit” texts in the components/TodoItem.jsx file. Let’s open the file and import the icon components:

import { FaTrash } from "react-icons/fa";
import { AiFillEdit } from "react-icons/ai";

After that, we’ll replace the “Delete” and “Edit” texts, so we have:

return (
  <li className={styles.item}>
    <div className={styles.content} style={viewMode}>
      {/* ... */}
      <button onClick={handleEditing}>
        <AiFillEdit />
      <button onClick={() => delTodo(itemProp.id)}>
        <FaTrash />
      {/* ... */}
    {/* ... */}

Let’s save the file and ensure the icons are rendered in the frontend.

Styling the React Icons

By default, React icons inherit the styles of the parent element. We can style the SVG icons directly in our CSS file by targeting the parent element:

.input-submit svg {
  color: #5e5e5e;
  font-size: 20px;
  margin-top: 2px;

We can also style individual icons using attributes like color, size, and className:

<button className="input-submit">

Like JSX elements, we can also style the icons using the style attribute. Let’s use this approach and update the submit button in the components/InputTodo.jsx file, so we have the following:

<button className="input-submit">
      color: '#5e5e5e',
      fontSize: '20px',
      marginTop: '2px',

We can save the file and see the update in the frontend.

Next, we will style the edit and delete button in the components/TodoItem.jsx file, so we have the following:

<button onClick={handleEditing}>
  <AiFillEdit style={{ color: "#5e5e5e", fontSize: "16px" }} />
<button onClick={() => delTodo(itemProp.id)}>
  <FaTrash style={{ color: "#5e5e5e", fontSize: "16px" }} />

Let’s save it and ensure it works as expected.


Styling React Icons With IconContext

The IconContext makes it easy to style multiple icons placed side-by-side. To use IconContext, we will import it from the react-icons:

import { IconContext } from "react-icons"

Afterward, we can wrap all the icons to style in a Provider component and assign an object with unique keys (provided by react-icons) and value pairs to the Provider value attribute.

The implementation should look like so:

    color: "darkcyan",
    style: { fontSize: "20px", color: "#ff0000" },
    className: "submit-iconn",
  <button className="input-submit">
    <FaPlusCircle />
    <FaPlusCircle />
    <FaPlusCircle />

Be aware that the color inside the style: {...} property will override the one assigned directly to the value attribute.

The IconContext usage may need to be clarified further because it uses the React context API. While we don’t have to know the context API to use it, we will cover the context API in the next lesson, and the implementation above will make more sense.
