deef-router

针对deef的思想设计的router，用于模块的初始化路由注册，提供history change时的callback环境。

Usages

// app.js
import deef from 'deef';
import createHashHistory from 'history/createHashHistory';
import deefRouter from './router';

export const app = deef();
export const connect = app.connect;
export const history = createHashHistory();
export const router = deefRouter({history});

// handler.js
import {router} from 'app';
router.register(rule, {onMatch, onBreakMatch}[, key]);

rule

1、express style path

const rule = '/:module/:page';
const rule = {path: '/', exact: true};

2、match pathname or search params

const rule = {pathname: '/Test'};
const rule = {pathname: '/TodoEntry', search: '?from=Test'};
const rule = {pathname: '/TodoEntry', search: {from: 'Test'}};
const rule = {pathname: '/TodoEntry', search: {from: location.search.from => {}}};

location.search是'?from=Test&otherKey=value'也会match上{search: '?from=Test'}

3、function match

const rule = ({pathname, search}) => {};

return null or plain object, must pass key param

onMatch(match, matchLog) match the rule

如针对rule '/Todo/:filter?'

location 从 /Test 到 /Todo/all时触发，此时无matchLog

location 从 /Todo/all 到 /Todo/active时触发，此时有matchLog(Array)

router.register('/:module', {
    onMatch({params: {module}}) {
        //do something with *module*
    }
});
router.register({
        pathname: '/TodoEntry',
        search: {from: 'Test'}
    }, {
    onMatch({pathname, search: {from}}) {
        //do something with *from*
    }
});

matchLogList意味着是在这同一个rule内，location的切换

onBreakMatch(matchLog) 从match到mismatch时触发

如针对rule '/Todo/:filter'

location 从 /Todo/all 到 /Todo/active不触发

location 再从 /Todo/active 到 /Test时触发

此时matchLog包含了两次match信息：

[/Todo/active, /Todo/all] // 时间轴顺序从晚到早

key

deef-router会根据key来保证同一个路由rule只注册一次（once on）

当rule不是function时，不是必须要传key的，会根据rule的特征自动生成唯一的key

当然，你也可以在任何调用的地方指定一个全局唯一的key来实现特殊逻辑，比如允许针对同一个rule注册两套路由规则
