# API Overview

> Every built-in module Elide provides and where each is documented.

JavaScript code gets the [`Elide` global](https://elide.help/docs/api-globals-elide), Node built-in modules, `elide:` database modules,
and Web globals. Suite results are in the [Compatibility Matrix](https://elide.help/docs/compatibility).

## Built-in modules

Node modules resolve with or without the `node:` prefix. Each `node:*` page lists only differences from
[nodejs.org/api](https://nodejs.org/api/).

Importing an unavailable module throws `ERR_UNKNOWN_BUILTIN_MODULE`.

### `elide:` aliases

`elide:X` returns the same module object as `node:X`. There is no `elide:compression`; use `node:zlib` or
`CompressionStream`.

## Elide modules

`elide:sqlite`, `elide:postgres`, and `elide:mysql` each export `Database`; see the [Database API](https://elide.help/docs/api-database).
