* [[Using TiddlyWiki as a component in node.js applications]]
* [[Constructing TiddlyWiki documents in other applications]]

! Internal Objects and Mechanisms

Internally, TiddlyWiki is built on a number of key objects and mechanisms:

* TiddlerObject
* WikiObject
* BootMechanism
* PluginMechanism
* ParsingMechanism
* RenderingMechanism
* DependencyMechanism
* RefreshMechanism
* MacroMechanism
* StoryMechanism
* EditingMechanism
* SavingMechanism
* SyncMechanism
* CommandMechanism
* ConfigMechanism

! Plugin Module Types

TiddlyWiki is built on a [[tiny microkernel|BootMechanism]] with all functionality provided as various types of plugin module:

* CommandModules
* ConfigModules
* EditorModules
* GlobalModules
* LibraryModules
* MacroModules
* ModuleModules
* ParserModules
* SaverModules
* StartupModules
* StoryViewModules
* SyncerModules
* TiddlerDeserializerModules
* TiddlerFieldModules
* TiddlerMethodModules
* TiddlerSerializerModules
* TreeNodeModules
* TreeUtilsModules
* UtilsModules
* WikiMethodModules
* WikiTextRuleModules

! Tree Nodes

The ParsingMechanism and the RenderingMechanism use a simple tree structure to represent both parsed WikiText and the HTML DOM structure of rendered content.

* TreeNode
* ElementNode
* EntityNode
* MacroNode
* RawNode
* TextNode

! Other Parsers

TiddlyWiki processes other [[ContentTypes|ContentType]] than WikiText using these parsers:

* OldWikiTextParser
* JsonParser
* ImageParser
* PlainTextParser
* TiddlyTextParser
* JavaScriptParser

! Deserializers

Deserializers are modules that read tiddlers from different text formats:

* RecipeFiles
* TiddlerFiles
* TiddlyWikiFiles

! Serializers

Serializers are modules that convert tiddlers to different text formats:
