pnpm 10.12 Introduces Global Virtual Store and Expanded Version Catalogs
pnpm 10.12.1 introduces a global virtual store for faster installs and new options for managing dependencies with version catalogs.
#Routing
####介绍
Routing是基于express的自动设置路由模块
####关于自动路由
Routing读取controllers文件夹内的xxxController.js文件,并缓存所有action函数
例:
以下controllers是目录结构
--- controllers/ controllers文件夹
|---- indexController.js controller文件
| |---- indexAction action函数
| |---- signupAction
| |---- ....
|
|---- homeController.js
|---- userController.js
|---- ....
|
|---- topic/
|---- indexController.js
|---- ....
以下views是目录结构
--- views/ views文件夹
|---- index/ 对应controller的文件夹
| |---- index.html 对应action的文件夹
| |---- signup.html
| |---- layout.html
| |---- ....
|
|---- home/
|---- user/
|---- ....
|
|---- topic/
| |---- index/
| |---- ....
当接受请求为/index/index时,自动路由到indexController.js内的indexAction函数,默认action为index,默认controller为indexController(可修改)
当接受请求为/index/index/id/123/type/submit时,自动路由同上,action函数内可获取参数,使用request.params['id']可以获取得值123,request.params['type']可以获取得值'submit'
自动路由没有找到对应action则抛出404错误转由错误视图控制,详见错误视图
action函数内可以使用respon.template函数调用对应views下相应视图
####关于错误视图
启用错误视图请确认设置
使用configure设置{"config.debug":0};
任何时刻抛出错误都可以在错误视图中捕获并调用对应视图,默认调用500视图对象
例:throw new Error('404') 会调用已定义的404错误视图
可以用使用routing.errorCode对象自定义视图,默认只有404和500视图
####关于api
configure
configure函数可以配置config.js的参数,而不用去修改config.js,参数允许传入一个对象
例: routing.configure({ 'web_default':'home', 'controller_default':'home', 'debug':1 })
参数请参阅config.js
注:configure函数需要init函数使用前调用,其他函数须执行init函数后执行
init
初始化Routing(必须)
customRoute
customRoute函数接受一个函数参数,用于自定义路由,拥有最高优先级,允许多次调用
例:
routing.customRoute(function() {
this.all('/index/user',function(req,res,next) {
.........
})
this.post('/:id',function(req,res,next) {
.........
})
})
参数函数内使用this定义路由,定义方法和express定义路由相同,this.get()|this.post()|this.all()
....
listen
listen函数用于配置好后初始化Routing并开启服务routing.listen(80);
其他变量
routing.app 存储express的server实例
routing.controllers 存储缓存的controller对象
routing.errorCode 存储存储错误视图对象
注:以上对象需要在调用init函数后使用
####安装和使用
安装方法 npm install routing
routing依赖于express 已经依赖了express不需要再安装express
var routing = require('routing');
routing.init();
routing.listen(80);
####其他
- Routing已经配置好生产环境(production)和开发环境(development)
- 默认存放controller文件夹为/controllers,默认使用ejs模板引擎
- 静态文件不会使用到自动路由
