# Modules & Integrations (/docs/cloud-code/modules)



Cloud Code supports all modules configured by the runtime loader.

Use this page as the catalog. Open [Module Reference](/docs/cloud-code/module-reference/overview) for practical, module-by-module details.

## How Modules Are Loaded [#how-modules-are-loaded]

```js
const HTTP = require('http');
const Mail = require('mail');
const _ = require('underscore');
```

Module IDs are case-insensitive and `.js` extension is optional.

## Start Here (Most Used Patterns) [#start-here-most-used-patterns]

* [http](/docs/cloud-code/module-reference/http) for external API calls.
* [mail](/docs/cloud-code/module-reference/mail) for transactional email.
* [mollie](/docs/cloud-code/module-reference/mollie) for payment checkout flows.
* [crypto](/docs/cloud-code/module-reference/crypto) and [jwt](/docs/cloud-code/module-reference/jwt) for signing/token work.
* [csv](/docs/cloud-code/module-reference/csv), [pdf](/docs/cloud-code/module-reference/pdf), [zip](/docs/cloud-code/module-reference/zip) for exports.

## Runtime Caveats [#runtime-caveats]

* Cloud modules wrap runtime exceptions and rethrow with stored Cloud Code error messages.
* Some modules return safe fallbacks (`''`, `null`, `{ error }`) instead of throwing on invalid input.
* Prefer `Nimbu.Site.env` for secrets instead of hardcoded keys.
