Simple guide for setting up OTG modes on the Raspberry Pi Zero

Raspberry Pi Zero OTG Mode

Simple guide for setting up OTG modes on the Raspberry Pi Zero - By Andrew Mulholland (gbaman).

The Raspberry Pi Zero (and model A and A+) support USB On The Go, given the processor is connected directly to the USB port, unlike on the B, B+ or Pi 2 B, which goes via a USB hub.
Because of this, if setup to, the Pi can act as a USB slave instead, providing virtual serial (a terminal), virtual ethernet, virtual mass storage device (pendrive) or even other virtual devices like HID, MIDI, or act as a virtual webcam!
It is important to note that, although the model A and A+ can support being a USB slave, they are missing the ID pin (is tied to ground internally) so are unable to dynamically switch between USB master/slave mode. As such, they default to USB master mode. There is no easy way to change this right now.
It is also important to note, that a USB to UART serial adapter is not needed for any of these guides, as may be documented elsewhere across the int

Rich text / HTML editors and frameworks

Strictly Frameworks

Abstracted Editors

These use separate document structures instead of HTML, some are more modular libraries than full editors

Debounced fetching to reduce number of requests when doing API proxying through GraphQL

Simple implementation of debounced fetching in GraphQL to allow merging of multiple rest / database requests into one. Although this example uses GraphQL, the debouncedFetch / fetchProgramPlaycount implementations could probably be used in any context to achieve the same result.

This approach was first described by @leebyron at graphql/graphql-js#19 (comment)

For example this allows turning ten requests for playcounts from this GraphQL query into just one:

{
  latestPrograms(first: 10) {
    name,

playcount
