Fully include Google web font in create-react-app build (without ejecting)

There are multiple ways of doing this.

1. Importing font

For example, for using Roboto, do

yarn add typeface-roboto

or

npm install typeface-roboto --save

In index.js:

import "typeface-roboto";

There are npm packages for a lot of open source fonts and most of Google fonts. You can see all fonts here. All the packages are from that project.

2. Download the font manually and add it to stylesheet

You can download fonts from fonts.google.com

Now, you can put the font in src/fonts/Lato.woff, and use it in your index.css.

@font-face {
    font-family: 'Lato';
    src: local('Lato'), url(./fonts/Lato.woff) format('woff');
}

For ttf font, you should give truetype instead of ttf as the parameter to the format

You can import this to your index.js to make it available

import './index.css';

You can do these in App.css, App.js as well. It's your preference.

1. Manually download the text package from Google Font

Head to any font that you wish to apply in your CSS, click the Download family to get a zip file.

Extract the zip file and move the folder into the src folder as below.

After that, refer to the below code, modify the src to the correct URL and put in the correct format. Here I used truetype, based on MDN

The available types are: "woff", "woff2", "truetype", "opentype", "embedded-opentype", and "svg".

The font-family attribute is the custom name. You can put any name you want.

@font-face {
  font-family: 'primary-font';
  src: url(./fonts//Sriracha/Sriracha-Regular.ttf) format('truetype');
}

.primary-font {
  font-family: primary-font;
}

2. Install the package @fontsource

Since Typefaces project is now deprecated, we can use the alternative package by the same author FontSource

Let me use Poppins as an example. First, download the package

npm install @fontsource/poppins --save

Next import the package in your index.js file

import "@fontsource/poppins";

Then use it as you wish

.primary-font {
  font-family: "Poppins";
}

Supported font list is in this Github repo directory.
