The Revealing Module Pattern in Javascript

Zach Caceres

Javascript does not have the typical 'private' and 'public' specifiers of more traditional object oriented languages like C# or Java. However, you can achieve the same effect through the clever application of Javascript's function-level scoping. The Revealing Module pattern is a design pattern for Javascript applications that elegantly solves this problem.

The central principle of the Revealing Module pattern is that all functionality and variables should be hidden unless deliberately exposed.

Let's imagine we have a music application where a musicPlayer.js file handles much of our user's experience. We need to access some methods, but shouldn't be able to mess with other methods or variables.

Using Function Scope to Create Public and Private Methods

 * This is an abbreviated "ES5" script (though it has some ES6 language, just not JSX, or dependencies on npm)
 * demonstrating how to get the WordPress "Gutenberg" SelectControl to allow dynamic options.
 *
 * It probably isn't elegant, but neither am I...I included more context than may be necessary.
 *
 * (SelectControl pukes on dynamic options because it completely dies, never to be seen again, if it
 * is sent an empty options array. This prevents that with a placeholder until your results come back.)
