title: $:/core/boot.js
type: application/javascript
The main boot kernel for TiddlyWiki. This single file creates a barebones TW environment that is just
sufficient to bootstrap the modules containing the main logic of the application.
On the server this file is executed directly to boot TiddlyWiki. In the browser, this file is packed
into a single HTML file along with other elements:
# bootprefix.js
# <module definitions>
# boot.js
The module definitions on the browser look like this:
$tw.defineModule("MyModule","moduletype",function(module,exports,require) {
// Module code inserted here
return exports;
});
In practice, each module is wrapped in a separate script block.
