A Gatsby theme for Material-UI: The fastest way to build server-side rendered Material-UI websites


// with npm
npm install gatsby-theme-material-ui @mui/material @emotion/react @emotion/styled

// with yarn
yarn add gatsby-theme-material-ui @mui/material @emotion/react @emotion/styled

Theme vs. Plugin

  • gatsby-plugin-material-ui solves FOUC, auto prefixing and minification.
  • gatsby-theme-material-ui uses the plugin under the hood, adds web fonts, meta-viewport, CSS baseline and mui theme support and has material ui styled gatsby link components

How to use

Edit gatsby-config.js

module.exports = {
  plugins: [`gatsby-theme-material-ui`],

Testing your installation

Replace the contents in your pages/index.js with the following

import React from "react";
import { Button, Box } from "@mui/material";

const IndexPage = () => {
  return (
    <Box p={4}>
      <Button variant="contained">Hello gatsby-theme-material-ui</Button>

export default IndexPage;

You should be greeted with a MUI button when you navigate to the root of your site.


You’ll see several references below to the “top-layout” theme. Its role is to prevent the Flash Of Unstyle Content.


Material-UI was designed with the Roboto font in mind. The Roboto font will be automatically loaded by gatsby-theme-material-ui. You can override this behavior as follows:

Edit theme.js

// src/gatsby-theme-material-ui-top-layout/theme.js

import { createTheme } from "@mui/material";

const theme = createTheme({
  typography: {
    fontFamily: [

export default theme;

Edit gatsby-config.js

// gatsby-config.js

module.exports = {
  plugins: [
      resolve: `gatsby-theme-material-ui`,
      options: {
        webFontsConfig: {
          fonts: {
            google: [
                family: `Montserrat`,
                variants: [`300`, `400`, `500`],

For more options, have a look at the plugin readme.

Note: If the changes you made in src/gatsby-theme-material-ui-top-layout/theme.js are not showing up, you might want to run gatsby clean to clean up the .cache folder and try again. This is required for newly shadowed files.


Create & Edit src/gatsby-theme-material-ui-top-layout/theme.js

import { createTheme } from "@mui/material";

const theme = createTheme({
  //   palette: {
  //     mode: 'dark',
  //   },

export default theme;
import React from "react";
import { Typography } from "@mui/material";
//import { Link } from "gatsby"
import { Link } from "gatsby-theme-material-ui";

const Page = () => (
      Check out my <Link to="/blog">blog</Link>!

export default Page;

The following components have also been adapted for use with Gatsby:

import {
} from "gatsby-theme-material-ui";

For <Button>s with href URLs, use the to attribute instead of href, to enable Gatsby link features.


Create & Edit src/gatsby-theme-material-ui-top-layout/components/top-layout.js

import React from "react";
import { Provider } from "react-redux";
import ThemeTopLayout from "gatsby-theme-material-ui-top-layout/src/components/top-layout";

import createStore from "../../state/createStore";

export default function TopLayout({ children, theme }) {
  const store = createStore();

  return (
    <Provider store={store}>
      <ThemeTopLayout theme={theme}>{children}</ThemeTopLayout>
