lockandload

lockandload

Lockandload is a minimal AMD-loader-compatible boilerplate to kickstart your website/single-page-app.

Gzipped, the essential script content amounts to roughly 1KB of code. Without compression it blows up to just under 2KB. Further minifying this code does not result in any significant gains, it would just hinder readability.

Features

• Less filling: 1KB of gzipped script content.
• Handminified to retain readable and maintainable code.
• It's so small, it can and should be inlined on your HTML page (which is also one of the reasons to handminify it only).
• Fully asynchronous script loader: AMD-compatible.
• Supports anonymous define() calls.
• Supports local require() calls (with one and two arguments).
• Supports implicit and explicit ['require'] dependencies.
• Does not support implicit nor explicit exports/module dependencies.
• Circular dependencies will silently hang in unresolved state.
• No extra diagnostic code to minimise code weight and optimise loading speed.
• Fully event driven, no polling timers.
• Standard events: domready and headready.
• Both high and low priority asynchronous loading of Javascript and CSS files.
• Leverages native browser speed for high priority loading (by getting out of the way).
• Legacy support for $(...) jquery riddled synchronous code.
• Legacy support for loading synchronous Javascript.
• Single-page-app support using $$(...) page refresh callbacks.
• Supports IE10 and up and all other webbrowsers.
• No config file, means: no syntax to learn, no config file parser code.

Requirements

It runs inside any webbrowser environment (starting at IE10 and up).

Usage

References

• Asynchronous Module Definition (AMD).
• Inspired by Curiosity-Driven's minimal loader: reducing the featureset of lockandload to that what that loader supports, we end up with 320 bytes for reduced-lockandload and 386 bytes for that loader.

Other loaders:

• RequireJS.
• curl.
