# Built in Nodes

This section contains a listing of all modules and nodes available out of the box in Midio.

## Core/std

The [core/std](/midio-docs/built-in-nodes/core-std.md) package contains the most basic building blocks needed for most Midio applications, like nodes for working with [numbers](/midio-docs/built-in-nodes/core-std.md#math), [strings](/midio-docs/built-in-nodes/core-std.md#strings), [objects](/midio-docs/built-in-nodes/core-std.md#map) and [lists](/midio-docs/built-in-nodes/core-std.md#list), as well as operations related to [cryptographic hashing](/midio-docs/built-in-nodes/core-std.md#hashing-crypto), [JSON](/midio-docs/built-in-nodes/core-std.md#json) and [CSV](/midio-docs/built-in-nodes/core-std.md#csv) data, [writing tests](/midio-docs/built-in-nodes/core-std.md#testing), [working with time](/midio-docs/built-in-nodes/core-std.md#time), [scheduling](/midio-docs/built-in-nodes/core-std.md#scheduling), [tracing](/midio-docs/built-in-nodes/core-std.md#tracing), [regular expressions](/midio-docs/built-in-nodes/core-std.md#match), [image manipulation](/midio-docs/built-in-nodes/core-std.md#image), and much more.

## HTTP

The http package contains nodes for [making](/midio-docs/built-in-nodes/http.md#fetchurl), and [responding](/midio-docs/built-in-nodes/http.md#endpoint), to http requests, as well as related to these tasks, like [url-encoding](/midio-docs/built-in-nodes/http.md#urlencodestring).
