Cheat Sheet: Simple Authentication in Rails 5 with has_secure_password

Cheat Sheet: Simple Authentication in Rails 6 with has_secure_password

The goal of this cheatsheet is to make it easy to add hand-rolled authentication to any rails app in a series of layers.

First the simplest/core layers, then optional layers depending on which features/functionality you want.

Anatomy of a JavaScript/Node project.

Directory structure for JavaScript/Node Projects

While the following structure is not an absolute requirement or enforced by the tools, it is a recommendation based on what the JavaScript and in particular Node community at large have been following by convention.

Beyond a suggested structure, no tooling recommendations, or sub-module structure is outlined here.

Directories

  • lib/ is intended for code that can run as-is
  • src/ is intended for code that needs to be manipulated before it can be used
