Typescript/functional component version
import React from "react";
import SyntaxHighlighter from "react-syntax-highlighter";
interface CodeBlockProps {
value: string;
language?: string;
}
export const CodeBlock = ({ language, value }: CodeBlockProps) => (
<SyntaxHighlighter language={language}>{value}</SyntaxHighlighter>

import React from "react";
import { Prism as SyntaxHighlighter } from "react-syntax-highlighter";
import { coy } from "react-syntax-highlighter/dist/cjs/styles/prism";
interface Props {
value: string;
language: string;
}
const CodeBlock: React.FC<Props> = (props: Props) => {
const { language, value } = props;
return (
<SyntaxHighlighter language={language} style={coy}>
{value ? value : ""}
</SyntaxHighlighter>
);
};
export default CodeBlock;
ReactMarkdown

<ReactMarkdown
