Deno provides polyfills for a number of built-in Node.js modules and globals.

<a href="/api/node/" class="docs-cta runtime-cta">Explore built-in Node APIs</a>

Node compatibility is an ongoing project - help us identify gaps and let us know
which modules you need by
[opening an issue on GitHub](https://github.com/denoland/deno).

## Globals

This is the list of Node globals that Deno supports. These globals are only
available in the `npm` package scope. In your own code you can use them by
importing them from the relevant `node:` module.
