There your are sitting in front of your brand-new dual processor XEON with a total of eight cores, 24G of RAM and a solid-state disk drive and you say to yourself, "I never have to worry about size and speed again!" Then your best customer wants you to move an application to a mobile device. Back to the real world.
That fact is, size matters! If you developing for mobile then browser caches, memory, CPU and network bandwidth are all signifcantly smaller than even an old PC. The #1 design requirement for bdLoad is to minimize the implementation size while implementing the AMD specification.
bdLoad is the smallest AMD loader available today. The implementation includes several switchable features that can be discarded when building optimized versions of the loader. The repository includes several prebuilt versions with feature sets targeted at specific problems as follows:
| Optimization Name | Description | size[1] | optimized code | closure-compiled | example |
|---|---|---|---|---|---|
| mini | smallest possible, webkit only, implements full AMD spec | 2.95K | see code | see code | try it |
| webkit | for webkit and/or mobile browsers; implements full AMD spec plus catches and reports errors and includes has.js core | 3.24K | see code | see code | try it |
| desktop | same as webkit plus IE suport | 3.42K | see code | see code | try it |
| basic | equivalent feature set to requirejs | 3.62K | see code | see code | try it |
1. size is closure-compiled and gzipped.
All of these versions were built with bdBuild.
