πŸ”§Initial setup

Setup @codegouvfr/react-dsfr in your project or start from a template

If you already had the DSFR installed in your project, let's start from scratch:

  • Remove @gouvfr/dsfr from your dependencies.

  • Remove the import ofdsfr.css, dsfr.module.js the favicon and the fonts.

  • Remove the data-fr-scheme (and data-fr-theme ) attribude from your <html/> tag

yarn add @codegouvfr/react-dsfr
Demo setup in production here: https://react-dsfr-vite-demo.vercel.app/

If you want a more complete starter with a Ready yo use stack that includes routing, autentication, internationalisation ect. you can also use this starter instead:

It's live here: https://vite-insee-starter.demo-domain.ovh/

Add these three scripts to your package.json:

package.json
"scripts": {
    "postinstall": "copy-dsfr-to-public",
    "predev": "only-include-used-icons",
    "prebuild": "only-include-used-icons"
}

Trigger the execution of the postinstall script by running:

yarn # Or 'npm install' or 'pnpm install'

Add the following tags in the <head />

index.html
<link rel="apple-touch-icon" href="/dsfr/favicon/apple-touch-icon.png" />
<link rel="icon" href="/dsfr/favicon/favicon.svg" type="image/svg+xml" />
<link rel="shortcut icon" href="/dsfr/favicon/favicon.ico" type="image/x-icon" />
<link rel="manifest" href="/dsfr/favicon/manifest.webmanifest" crossorigin="use-credentials" />

<link rel="stylesheet" href="/dsfr/utility/icons/icons.min.css" />
<link rel="stylesheet" href="/dsfr/dsfr.min.css" />
src/main.tsx
import React from "react";
import ReactDOM from "react-dom/client";
import { App } from "./App";
import { startReactDsfr } from "@codegouvfr/react-dsfr/spa";
startReactDsfr({ defaultColorScheme: "system" });

ReactDOM.createRoot(document.getElementById("root") as HTMLElement).render(
  <React.StrictMode>
    <App />
  </React.StrictMode>
);

You're all set! Next step for you is to setup the integration with your routing library (react-router for example).

Avoiding or flash of unstyled text (FOUT)

You can avoid having a flash of unstyled text by preloading the font variant used on your homepage (look in the network tab of your browser dev tools what are the font downloaded initially).

Add the following tags in the <head />

index.html
<!--<link rel="preload" href="/dsfr/fonts/Marianne-Light.woff2" as="font" crossorigin="anonymous" />-->
<!--<link rel="preload" href="/dsfr/fonts/Marianne-Light_Italic.woff2" as="font" crossorigin="anonymous" />-->
<link rel="preload" href="/dsfr/fonts/Marianne-Regular.woff2" as="font" crossorigin="anonymous" />
<!--<link rel="preload" href="/dsfr/fonts/Marianne-Regular_Italic.woff2" as="font" crossorigin="anonymous" />-->
<link rel="preload" href="/dsfr/fonts/Marianne-Medium.woff2" as="font" crossorigin="anonymous" />
<!--<link rel="preload" href="/dsfr/fonts/Marianne-Medium_Italic.woff2" as="font" crossorigin="anonymous" />-->
<link rel="preload" href="/dsfr/fonts/Marianne-Bold.woff2" as="font" crossorigin="anonymous" />
<!--<link rel="preload" href="/dsfr/fonts/Marianne-Bold_Italic.woff2" as="font" crossorigin="anonymous" />-->
<!--<link rel="preload" href="/dsfr/fonts/Spectral-Regular.woff2" as="font" crossorigin="anonymous" />-->
<!--<link rel="preload" href="/dsfr/fonts/Spectral-ExtraBold.woff2" as="font" crossorigin="anonymous" />-->
