As someone diving into the realm of JavaScript design patterns with limited experience using require or import, I find myself in a situation where I have a single module containing various functions and private variables all within one file. It has become clear that dividing this module into multiple files would not only be beneficial for best practices but also improve clarity. The basic structure of the module's pattern is illustrated below:
let Module = () => {
//private variables
let private1,
private2;
//public functions
function addDataToPrivate1 (data) {
private1 = manipulateData(data);
}
function addDataToPrivate2 (data) {
private2 = manipulateData(data);
}
//private function to process data
function manipulateData(data) {
return data.trim();
}
return {
addDataToPrivate1: addDataToPrivate1,
addDataToPrivate2: addDataToPrivate2,
}
}
My goal now is to separate these functions into distinct files, such as individual files for addDataToPrivate1, addDataToPrivate2, and manipulateData. Furthermore, I aim to keep private1 and private2 accessible privately within the Module for other methods to leverage. How can I effectively split the code into various files and then utilize the import feature to gather the different components of the module together?
The ultimate objective is to create something that users can seamlessly incorporate into their projects, similar to how packages like d3js or jQuery are used. For instance, by following the example provided above, users could easily assign the module to a variable and employ it like this:
let moduleInstance = Module();
moduleInstance.addDataToPrivate1(' some data here ');
moduleInstance.addDataToPrivate2(' some data here2 ');
