uni-app Baidu Mini Program Support

This package provides complete Baidu Mini Program runtime and compiler support for the uni-app cross-platform development framework. It enables Vue.js applications to be compiled and run on the Baidu Smart Mini Program platform while maintaining uni-app's unified development experience and API compatibility.

Package Information

  • Package Name: @dcloudio/uni-mp-baidu
  • Package Type: npm
  • Language: JavaScript/TypeScript
  • Installation: npm install @dcloudio/uni-mp-baidu

Core Imports

// Main uni API (default export)
import uni from "@dcloudio/uni-mp-baidu";

// Or import specific functions
import { createApp, createPage, createComponent } from "@dcloudio/uni-mp-baidu";

For CommonJS:

// Main uni API
const uni = require("@dcloudio/uni-mp-baidu");

// Or destructure specific functions
const { createApp, createPage, createComponent } = require("@dcloudio/uni-mp-baidu");

Basic Usage

import uni, { createApp, createPage } from "@dcloudio/uni-mp-baidu";

// Create a Baidu Mini Program app from Vue app
const app = createApp({
  onLaunch() {
    console.log('App launched');
  }
});

// Create a page from Vue component options
const page = createPage({
  data() {
    return { message: 'Hello Baidu Mini Program' };
  },
  onLoad() {
    console.log('Page loaded');
  }
});

Architecture

The package is structured around several key components:

  • Runtime API: Core uni-app API implementation with Baidu-specific adaptations
  • Component System: Vue.js component to Baidu mini program component conversion
  • Event System: Event handling bridge between Vue.js and Baidu mini program events
  • API Translation: Automatic translation between uni-app APIs and native Baidu swan APIs
  • Build Integration: Webpack configuration and compilation support
  • Automation Support: Built-in testing and debugging capabilities

Capabilities

Runtime API

Core uni-app API implementation providing access to all platform capabilities through a unified interface. The main uni object provides cross-platform APIs with Baidu-specific adaptations.

// Main uni object (default export)
export default uni: {
  // Unit conversion
  upx2px(number: number, newDeviceWidth?: number): number;
  
  // Interceptor system
  addInterceptor(method: string, interceptor: Interceptor): void;
  removeInterceptor(method: string, interceptor?: Interceptor): void;
  
  // Event system
  $on(event: string, handler: Function): void;
  $off(event: string, handler?: Function): void;
  $once(event: string, handler: Function): void;
  $emit(event: string, ...args: any[]): void;
  
  // Provider and payment APIs
  getProvider(options: ProviderOptions): Promise<ProviderResult>;
  requestPayment(params: PaymentParams): Promise<any>;
  
  // Media query observer
  createMediaQueryObserver(): MediaQueryObserver;
  
  // Navigation APIs
  navigateTo(options: NavigateToOptions): Promise<any>;
  redirectTo(options: RedirectToOptions): Promise<any>;
  navigateBack(options?: NavigateBackOptions): Promise<any>;
  navigateToMiniProgram(options: NavigateToMiniProgramOptions): Promise<any>;
  navigateBackMiniProgram(options?: NavigateBackMiniProgramOptions): Promise<any>;
  
  // System APIs
  getSystemInfo(options?: SystemInfoOptions): Promise<SystemInfo>;
  getSystemInfoSync(): SystemInfo;
  getAccountInfoSync(): AccountInfo;
  
  // Network APIs
  request(options: RequestOptions): Promise<RequestResult>;
  connectSocket(options: ConnectSocketOptions): SocketTask;
  
  // Media APIs
  previewImage(options: PreviewImageOptions): Promise<any>;
  createCanvasContext(canvasId: string, component?: any): CanvasContext;
  getRecorderManager(): RecorderManager;
  getBackgroundAudioManager(): BackgroundAudioManager;
  
  // Scanner API
  scanCode(options?: ScanCodeOptions): Promise<ScanCodeResult>;
  
  // Share API
  showShareMenu(options?: ShowShareMenuOptions): Promise<any>;
};

Runtime API

Application and Component Creation

Functions for converting Vue.js applications and components into Baidu Mini Program format with full lifecycle support.

function createApp(instance: VueAppInstance): BaiduMiniProgramApp;

function createComponent(vueOptions: VueComponentOptions): BaiduMiniProgramComponent;
function createSubpackageApp(instance: VueAppInstance): BaiduMiniProgramSubpackageApp;
function createPlugin(instance: VueAppInstance): BaiduMiniProgramPlugin;

App and Component Creation

Navigation APIs

Page navigation and routing functionality for navigating between pages and mini-programs with platform-specific adaptations for Baidu Smart Programs.

function navigateTo(options: NavigateToOptions): Promise<any>;
function redirectTo(options: RedirectToOptions): Promise<any>;
function navigateBack(options?: NavigateBackOptions): Promise<any>;
function navigateToMiniProgram(options: NavigateToMiniProgramOptions): Promise<any>;
function navigateBackMiniProgram(options?: NavigateBackMiniProgramOptions): Promise<any>;

Navigation APIs

System APIs

Device and system information APIs providing access to device capabilities, account information, and system configuration.

function getSystemInfo(options?: SystemInfoOptions): Promise<SystemInfo>;
function getSystemInfoSync(): SystemInfo;
function getAccountInfoSync(): AccountInfo;

System APIs

Network APIs

Network communication APIs for HTTP requests and WebSocket connections with Baidu-specific protocol adaptations.

function request(options: RequestOptions): Promise<RequestResult>;
function connectSocket(options: ConnectSocketOptions): SocketTask;

Network APIs

Vue Integration

Utilities for seamlessly integrating Vue.js components with Baidu Mini Program runtime, handling data binding, event systems, and lifecycle management.

function initComponentInstance(instance: VueInstance, options: ComponentOptions): void;
function handleEvent(event: BaiduMiniProgramEvent): void;
function setModel(target: any, key: string, value: any, modifiers: ModelModifiers): void;

Vue Integration

Build and Compilation

Configuration and compilation utilities for transforming Vue.js applications into Baidu Mini Program format during the build process.

const options: {
  cssVars: CSSVariables;
  extnames: FileExtensions;
  filterTag: string;
