Question 1

How do I sanitize HTML output from Marked?

Accepted Answer

Marked does not sanitize HTML by default. You must use an external library like DOMPurify on the output. For example, wrap marked.parse() with DOMPurify.sanitize() to prevent XSS attacks, as recommended in the README warning.

Question 2

Marked vs marked-react: which one should I use?

Accepted Answer

Marked is a general-purpose markdown parser for various environments, while marked-react is a React-specific wrapper. Use Marked if you need low-level control across platforms; choose marked-react for React projects with integrated components.

Question 3

How can I extend Marked with custom syntax?

Accepted Answer

Marked supports extensibility through custom renderers and tokenizers. Check the documentation on extensibility to define new rules, but note that it requires understanding the low-level API and may involve more code than higher-level libraries.

Question 4

Is Marked safe for user-generated content?

Accepted Answer

Not without additional steps. Since Marked doesn't sanitize HTML, you must manually implement security measures. Always sanitize the output with libraries like DOMPurify to avoid vulnerabilities from malicious markdown input.

Question 5

How to use Marked in a Node.js server?

Accepted Answer

Install Marked via npm and import it in your Node.js code. Use marked.parse() to convert markdown strings to HTML, but remember to handle sanitization and error checking for production use.

Question 6

Performance: how does Marked compare to other parsers like Showdown?

Accepted Answer

Marked is often faster due to its low-level, non-blocking design. However, benchmarks can vary by use case, so test in your environment. Its speed comes at the cost of requiring manual security handling.
