Part of the upcoming AWS integration work is a custom build of TiddlyWiki that can run as an Amazon Lambda function. These tweaks enable the new build to control the loading of SJCL, the package info, and any preloaded tiddlers.

# <module definitions>

# Boot.js

See Boot.js for further details of the boot process.

Information about each module is kept in an object with these members:

|
moduleType: type of module
|
|
definition: object, function or string defining the module; see below
|
|
exports: exports of the module, filled in after execution
|
|
|
|
The `definition` can be of several types:
|
|
|
|
* An object can be used to directly specify the exports of the module
|
|
* A function with the arguments `module,require,exports` that returns `exports`
|
|
* A string function body with the same arguments
|
|
|

Each moduleInfo object is stored in two hashmaps: $tw.modules.titles and $tw.modules.types. The first is indexed by title and the second is indexed by type and then title
