How to load and render Markdown files into your Vite React app using Typescript

Backstory (Skip it if you want)

Ok so I was **REALLY **struggling with this one.

I’m building an app, and for ease of use and maintenance, for the terms and conditions, privacy policy and other stuff I wanted to write them in markdown instead of plain TSX.

I could not find anything on my particular environment: Vite + React + Typescript + ChakraUI.

So here’s what worked for me:

The solution

Test your markdown flow

First thing’s first, get your markdown rendering straight:

Install react-markdown :

npm i react-markdown

If you don’t use ChakraUI skip this step:

Install chakra-ui-markdown-renderer :

ChakraUI messes with the typical <h2> and other HTML stuff, so react-markdown won’t work unless we pass a custom renderer:

npm i chakra-ui-markdown-renderer

Now create a simple component to test your markdown:

import { Box } from "@chakra-ui/react";
import ReactMarkdown from "react-markdown";
import ChakraUIRenderer from "chakra-ui-markdown-renderer";

const MarkdownTest = () => {
  return (
    <Box>
      <ReactMarkdown
        children={`# This is markdown!`}
        components={ChakraUIRenderer()} // Skip this if you don't use ChakraUI
        skipHtml // Skip this if you don't use ChakraUI
      />
    </Box>
  );
};

export default MarkdownTest;

You should see markdown when rendering this component. If so, let’s move on to how to import markdown files.

Importing Markdown Files

Now for the part I struggled with the most.

First we need to tell Typescript that markdown files are “importable” and not a usual module. Go to your vite-env.d.ts and add this line:

declare module "*.md";

Cool? Cool.

Now we need to tell vite how to actually get the data inside of the markdown files. Go to your vite.config.ts and create a custom plugin for this:

import { defineConfig } from "vite";
import react from "@vitejs/plugin-react";

// https://vitejs.dev/config/
export default defineConfig({
  plugins: [
    react(),
    // Custom plugin to load markdown files
    {
      name: "markdown-loader",
      transform(code, id) {
        if (id.slice(-3) === ".md") {
          // For .md files, get the raw content
          return `export default ${JSON.stringify(code)};`;
        }
      },
    },
  ],
});

We’re almost there! !

Now go and create a markdown file, for instance test.md .

In your component import it and add it and pass it to react markdown! !

import { Box } from "@chakra-ui/react";
import ReactMarkdown from "react-markdown";
import ChakraUIRenderer from "chakra-ui-markdown-renderer";

// Import markdown files
import markdown from "test.md";

const MarkdownTest = () => {
  return (
    <Box>
      <ReactMarkdown
        // Pass it as children
        children={markdown}
        components={ChakraUIRenderer()} // Skip this if you don't use ChakraUI
        skipHtml // Skip this if you don't use ChakraUI
      />
    </Box>
  );
};

export default MarkdownTest;

That’s it! You should see your markdown file rendered in all of its glory.

Hope these hours of research help someone. Cheers!
