A tiny modular Javascript utility library

Overslash is an utility library as Underscore and Lodash. However, Overslash doesn't pretend to compete with these honorable libraries. Overslash implements only a small subset of the functions that can be found in these library.

Overslash ambition is quite different. Overslash is modular. You can build a version with only the subset of the functions you need.

Then, you can embed it in your own library. So, you can ship your library without any external dependencies.

How to embed Overslash in your library

Overslash is included in a Javascript module pattern. It exports only the variable overslash outside this module. Thus, you can safely embed Overslash in your library without any risk to pollute your namespace.

Overslash module pattern looks like this:

(function(root, factory) {
  'use strict';

  if (typeof define === 'function' && define.amd) {
    define([''], factory);
  } else if (typeof exports === 'object') {
    module.exports = factory();
  } else {
    // Browser globals.
    root.overslash = factory();
  }
}(this, function() {
  'use strict';

  var overslash = {
    // ...
  };

  return overslash;
}));

You just need to replace this by the namespace of your library:

(function(root, factory) {
  // ...
    // Browser globals.
    root.overslash = factory();
  }
}(this, function() { // <--- replace this by your library namespace
  // ...

You can now add a reference to Overslash inside your library:

var myLibraryName = {};

// Embed Overslash and replace 'this' by 'myLibraryName':
(function());

// You can now access to Overslash:
var _ = myLibraryName.overslash;
