![Architecture diagram][1]
|
|
|
|
|
|
StackEdit uses [RequireJS][2] for asynchronous module definition ([AMD][3]).
|
|
|
|
|
|
----------
|
|
|
|
|
|
### core
|
|
|
|
The `core` module is responsible for:
|
|
|
|
- creating the layout (using [UI Layout][4])
|
|
- creating the editor (using [PageDown][5])
|
|
- loading/saving the settings
|
|
- running period tasks
|
|
- detecting the user activity
|
|
- checking the offline status
|
|
|
|
|
|
----------
|
|
|
|
|
|
### fileMgr
|
|
|
|
The `fileMgr` module is responsible for:
|
|
|
|
- creating and deleting local files
|
|
- switching from one file to another
|
|
|
|
#### FileDescriptor
|
|
|
|
The `FileDescriptor` class represents a local file. A `FileDescriptor` object has the following properties:
|
|
|
|
- `fileIndex`: the unique string index of the file in the file system
|
|
- `title`: the title of the document
|
|
- `content`: the content of the document
|
|
- `syncLocations`: a map containing all the associated [`syncAttributes`][7] objects with their `syncIndex` as a key
|
|
- `publishLocations`: a map containing all the associated [`publishAttributes`][8] objects with their `publishIndex` as a key
|
|
|
|
And the following methods:
|
|
|
|
- `addSyncLocation(syncAttributes)`: associates a [`syncAttributes`][9] object with the file
|
|
- `removeSyncLocation(syncAttributes)`: unassociates a [`syncAttributes`][10] object with the file
|
|
- `addPublishLocation(publishAttributes)`: associates a [`publishAttributes`][11] object with the file
|
|
- `removePublishLocation(publishAttributes)`: unassociates a [`publishAttributes`][12] object with the file
|
|
|
|
#### fileSystem
|
|
|
|
The `fileSystem` module is a map containing all the [`FileDescriptor`][6] objects with their `fileIndex` as a key
|
|
|
|
|
|
----------
|
|
|
|
|
|
### synchronizer
|
|
|
|
The `synchronizer` module is responsible for:
|
|
|
|
- creating a new local file from a sync location (import)
|
|
- creating a new sync location from a local file (export)
|
|
- running 2 ways synchronization (upload and download) for all sync locations
|
|
|
|
#### synchronizer's providers
|
|
|
|
A [`provider`][13] module can be associated with the `synchronizer` module if it implements the following functions:
|
|
|
|
- `importFiles()`: downloads one or multiple files and create local files associated with the sync locations
|
|
- `exportFile()`: uploads a local file to a new sync location
|
|
- `syncDown()`: performs a download of all the changes operated on all sync locations
|
|
- `syncUp()`: performs an upload of a change to a sync location
|
|
|
|
#### syncAttributes
|
|
|
|
A `syncAttributes` object is an object that describes a sync location. Attributes differ from one provider to another except for the following:
|
|
|
|
- `syncIndex`: the unique string index of the publish location
|
|
- `provider`: the [`provider`][14] module that handles the sync location
|
|
|
|
|
|
----------
|
|
|
|
|
|
### publisher
|
|
|
|
The `publisher` module is responsible for:
|
|
|
|
- creating new publish locations
|
|
- updating existing publish locations
|
|
|
|
#### publisher's providers
|
|
|
|
A [`provider`][15] module can be associated with the `publisher` module if it implements the following functions:
|
|
|
|
- `newPublishAttributes()`: returns a new [`publishAttributes`][16] object in order to create a new publish location
|
|
- `publish()`: performs publishing of one publish location
|
|
|
|
#### publishAttributes
|
|
|
|
A `publishAttributes` object is an object that describes a publish location. Attributes differ from one provider to another except for the following:
|
|
|
|
- `publishIndex`: the unique string index of the publish location
|
|
- `provider`: the [`provider`][17] module that handles the publish location
|
|
- `format`: the publishing format for the publish location. It can be:
|
|
- `markdown` for Markdown format
|
|
- `html` for HTML format
|
|
- `template` for template format
|
|
|
|
