Add code snippets like below with PrismJS. Create your custom theme here & import the JS & CSS provided at the bottom of the page in the index.html file.

Note: Only import languages that are actually used in your application as every language imported increases the size of the application.

const snippet = `
function fun () {
  return (
    <div>Hello there!</div>
  )
}`

<Code snippet={snippet} lang='jsx' />
