Developer tips

Overview

There are as many different ways of developing software for single board computers, like the Raspberry Pi, as there are developers who do it. Likewise, opinions vary as to which approach is best. Ultimately it's the process that works for best for you that prevails. This briefly describes two approaches used by contributors to RaspAP.

Remote host update

Project contributor @glaszig maintains a working copy of RaspAP on his workstation and automatically copies changes over to the Pi. He's written this handy script to automate the process by way of fswatch. The script watches a local (dev) directory and pushes changes to the remote target (the Pi, in this case) via scp, or secure copy. This way, you can use your preferred integrated development environment (IDE) and simply push updates in the background to a remote system. More on fswatch here.

An ancillary benefit with this method is that uncommitted changes to your local working copy are less vulnerable to being lost, in the event the remote system becomes inaccessible. It is also less susceptible to potential 'over-the-wire' network latency issues.

Direct access via terminal

If you're comfortable using a Linux-based text editor, developing directly on the Pi via the terminal is an alternate approach. This trades the IDE for Vim, Emacs or some other editor. While these tend to have steeper learning curves, the upside is their extreme portability and universality. That is, human readable, plain-text configuration files for terminal programs (often called 'dotfiles') are generally much more portable than those for IDEs.

This means that you could, for example, save your dotfiles to GitHub and in effect "bring them with you" to whichever system you happen to be working on. The availability of Vim or Emacs is generally much greater than OS-specific IDEs, so in seconds (or at most a few minutes) you can setup your familiar dev environment. With the addition of tmux, you can have multiple panes in a single terminal window. Here is an excellent guide to getting started with the terminal.
