uni-vue-router
根据uniapp的路由方法封装的框架; 主要参考:vue-router
功能
- 根据pages.json自动生成路由表
- 支持typescript
- 支持最基本的vue-router的API用法
开发设置
npm install --save uni-vue-router
配置 ./vue.config.js
//为了读取 pages.json,uni-app框架是阻断了通过 webpack 方式读取 pages.json
const webpack = require('webpack')
function readPagesJSON() {
const path = require('path');
const fs = require('fs');
const jsonFilePath = path.join(__dirname, './src/pages.json')
if (!fs.existsSync(jsonFilePath)) {
throw new Error(jsonFilePath + ' 不存在')
}
return fs.readFileSync(jsonFilePath, 'utf8')
}
module.exports = {
configureWebpack: {
plugins: [
// new BundleAnalyzerPlugin(),
new webpack.DefinePlugin({
PAGES_JSON: JSON.stringify(readPagesJSON())
})
]
}
}
增加 src/router.js
import Router, { Route, NextFn } from 'uni-vue-router';
Vue.use(Router);
// 通过 pages.json 转换路由信息
const router = new Router({
pagesJSON: PAGES_JSON // PAGES_JSON 在 build的时候会被 webpack 替换
);
new App({
router,
render: h => h(App),
}).$mount();
修改 src/App.vue 初始化路由
onLaunch(options) {
//first time init current route
this.$router.transitionTo({
path:options && options.path,
query:options && options.query
});
console.log('App Launch');
},
基本用法
路由跳转
注意: 传入的pages.json中如果缺少name,框架会自动通过path生成一个横线分割的 name
this.$router.push({
name:'pages-bookings-detail-index',
path:'/pages/bookings/detail/index'
})
路由变化监听
@Watch('$route',{
immediate: true
})function(newVal:Route,oldVal:Route) {
console.log('$route changed!',newVal,oldVal,this.$route)
}
路由钩子
router.beforeEach((to: Route, from: Route, next: NextFn) => {
console.log('[beforeEach] to from:', to, from);
if (to.name === 'bookings-detail') {
// return;
}
next();
});
router.beforeEach((to: Route, from: Route, next: NextFn) => {
console.log('[beforeEach]:', to, from, next);
next();
});
router.afterEach((to: Route, from: Route) => {
console.log('[afterEach] to from:', to, from);
});
router.afterEach((to: Route, from: Route) => {
console.log('[afterEach]:', to, from);
});
API
路由方法映射关系
{
push: 'navigateTo',
pushTab: 'switchTab',
replace: 'redirectTo',
replaceAll: 'reLaunch',
back: 'navigateBack',
};
api reference vue-router API
push(location: RawLocation, onComplete?: VoidFn, onAbort?: VoidFn)
push(location).then(onComplete).catch(onAbort)
pushTab(location: RawLocation, onComplete?: VoidFn, onAbort?: VoidFn)
beforeEach(beforeHook, onComplete?: VoidFn, onAbort?: VoidFn)
afterEach(afterHook, onComplete?: VoidFn, onAbort?: VoidFn)
transitionTo(location: RawLocation) //在 onTabItemTap以及onLaunch里面 这种非手动调用的地方手动调用更新 $route
uniapp手势回退监听的fix方案
解决uniapp的header上点back或者手动滑后退监听不到导致$route.stack错误的方案,主要是解决埋点之类的需求
@Component
export class RouterMixin extends Vue {
onUnload() {
let navigationMethodName = this.$router.navigationMethodName
// @ts-ignore
if (this.mpType === 'page' && (!navigationMethodName || navigationMethodName === 'push') && this.$router.stack.length > 1) {
this.$router.stack.pop();
this.$router.index--;
this.$router.current = this.$router.stack[this.$router.index];
}
// @ts-ignore
this.$router.navigationMethodName = '';
}
}
Vue.mixin(RouterMixin)
通过目录结构自动生成路由(2.0.0后废弃的方案)
此方案在版本2.0.0 后废弃 由于使用 require.context 机制,此方案的工程体积会随着page增多而加速膨胀 原因
目录结构
├── pages
│ ├── bookings
│ │ ├── detail
│ │ │ └── index.vue
│ │ ├── index.vue
[
{path: "/pages/bookings/detail/index",name:"bookings-detail"},
{path: "/pages/bookings/index", name: "bookings"}
]
约定结构
- 路由目录下必须有一个 index.vue
- 基于第一条:path (index.vue文件路径,也是路由path) => name (路由名字) 的映射关系 例子: 'pages/bookings/detail/index.vue' => bookings-detail
- 基于第二条:文件名不能包含中横线,容易导致路径冲突(eg: pages/bookings/detail/index.vue 跟 pages/bookings-detail/index.vue 会转为相同的name)
其它
uni自带跳转问题
- 无路由 watch
- 页面路径不好聚合管理
- 无路由钩子
- 需要手动拼接参数列表
- 传特殊字符时会发现参数被截断(比如传二维码信息)原因是不能包括(=&?)等特殊字符
- 无路由嵌套
问题
- router-view (uni-app 访问不到root.$parent)
- router-link (uni-app 不支持在Vue.install里面挂载组件,所以现在的router-link是无效的)
