TooNote - WebClient

web client, also applied in electron and webview based desktop app.

Structure

Code was splited in layers, and communicate by events and methods (on vue $ref instance).

Each Layer produces an individual dist file, so they can be used seperately.

View Layer: render views fro user state / note list / background tasks / note editor / note preview etc.
Controller Layer: hold the global state, work with Model Layer and UI layer.
Model Layer: local cache / data storage / network io etc. May be different in different platforms, but try to keep the same API as much as possible.
SDK for TooNote API: data fetch / post for TooNote API.

The final WebClient for TooNote will be built in different combines. for example:

Editor Version: Just the Editor in View Layer, plus a little logic code to open/save files. No storage or note management included.
Lite Version: View Layer + Controller Layer + Model Layer (for local usage), No need to connect the server, No login, No data sync.
Full Version: View Layer + Controller Layer + Model Layer + TooNote SDK, the full functional TooNote version, data stores in remote server of TooNote.

View Layer

The UI includes the followings:

Sidebar
- UserInfo show information of current login user.
- NoteTree show the index of a notebook.
Editor the markdown editor.
Preview preview of current content in editor.

The interface of View Layer is an instance of WebClientView, includes the following members:

app the main Vue app instance, it will emit events and provide several methods to interact with external world. You should call $mount() method to mount the app to the container DOM element in page.
setData() a method to inject data for each UI part.

Data Interface

The state of view is totally decided by the data it receives. In order to inject the data from outside world, you shoud call setData() method of View Layer.

const userInfo = {
    name: 'TooBug',
    avatarUrl: 'https://avatars3.githubusercontent.com/u/1243593?s=100&v=4',
    labels: ['SVIP'],
}
webClientView.setData('userInfo', userInfo);

The value of data should be a plain object. You can call the method any times as you wish, View Layer will respond to the data change, and show the latest UI.

But, for better performance, you should not override the original data object (userInfo in this example), in any case, you should just update the value of a member. (for example, userInfo.name = 'TooooBug'.)

Full list of data name and structure:

userInfo used by UserInfo component
- name user name
- avatarUrl url of user avatar
- labels an array of labels
editor used by Editor component and Preview component
- content the content (in markdown)
notebook current notebook, used by NoteTree component
- title title of notebook
- categories an array of categories in notebook
  - {category} the element of the array above (this key not exist)
    - {key} the key of above object property means the category name, for example category1
    - {value} an array of notes.
      - {note} the element of the array above (this key not exist)
        
        id note id
        
        title note title

An example of notebook:

{
    title: 'notebook1',
    categories: {
        'category1': [{
            id: '1',
            title: 'note1'
        }, {
            id: '2',
            title: 'note2'
        }],
        'category2': [{
            id: '3',
            title: 'note3'
        }, {
            id: '4',
            title: 'note4'
        }],
    }
}

Events

Events are emitted when user interact with the UI. Each event follows the following format:

event name: prefix.eventName the prefix will be the module. Modules may not map to the UI parts.
event data: in an object.

Full list of events:

note prefix, means note related events
- note.new create a new note
  - data event data
    - context
      - type context type, category | note
      - id category id or note id
    - from the source of event, value can be menu | noteTree | shortcut
- note.delete delete a note
  - data event data
    - id noteId
- note.rename
- note.move
- note.switchActive switch current active note
  - data event data
    - id noteId
category prefix, means category related events
notebook prefix, means notebook related events
editor prefix, means editor related events
- editor.change content changed
- editor.scroll editor view scrolled
preview prefix, means preview related events
- preview.linkClick user clicked the link in preview
user prefix, means user related events
- user.login login
- user.logout logout

Methods

In most cases, you should inject an data item to control the behavior of View Layer. But in some cases, call a method is an easier way to go.

preivew.scrollTo(y) scroll preview section to y px.

Controller Layer

Hold the global state, work with Model Layer and UI layer. Since it's called WebClient, it will work like tranditional web application: just hold little data in client side. Most user actions will trigger network communications.

Model Layer

local cache / data storage / network io etc. May be different in different platforms, but try to keep the same API as much as possible.

SDK for TooNote API

data fetch / post for TooNote API.
