Small program big world
1 Introduction
1.1 What problem does the applet solve
1.2 Applet technology stack
- HTML/CSS/JavaScript
- NodeJS
- Mobile adaptation
- HTTP protocol / HTTPS
- OAuth2 authentication
- GIT
1.3 The main applet platform
1.3 Technology like applets
- Cordova: rendering through webview, calling system services through plugins
- PWA：Service Worker和Push API
- React Native / Weex: JavaScript is executed through JavascriptCore, etc. and interacts with Native components through Bridges
- Flutter: Dart directly interacts with the UI library of the independent system
2. Small program technical architecture
2.1 File structure and its meaning
.json后缀的JSON配置文件
.wxml后缀的WXML模板文件- Essentially HTML template
- Has a specific label
- Take over some simple logical judgments
- JS does not directly manipulate the DOM, only responsible for set data based on data-driven mode
.wxss后缀的WXSS样式文件- Provide rpx unit Provide screen width and 750 ratio
- Streamlined CSS
- Provide global and local CSS
.js后缀的JS脚本逻辑文件- Responsible for logical interaction
- Three constructors of APP, Page and Component
- Callable system API
2.2 Dual thread model
2.3 Life cycle
2.4 Components
2.5 Other
- Plugin mechanism
- Cloud functions
- Games
3. Development and release process
- The developer registers the applet on the applet platform to obtain the APPID
- Initialize the code and complete the code warehouse configuration
- Develop code and debug
- Upload and post
4. Development of small programs
4.1 Multi-terminal isomorphic framework
- Significance: Write multiple adaptations at one time, and synchronize each end at one iteration
- Take advantage of the Web and dynamically adapt to various platforms
kbone ：
4.2 Automation
- Control the applet to jump to the specified page
- Get applet page data
- Get applet page element status
- Trigger applet element binding event
- Inject code snippets into AppService
- Call any interface on wx object
4.3 Hardware framework
4.4 Alipay Cloud IDE
4.5 W3C Mini Program Working Group
