最近在研究NativeScript,NativeScript使用TypeScript,因而就順便研究了ts。github
不得不提到NativeScript源碼學習,感受學習到了很多東西,順便也從上面扣了一個依賴注入的框架下來用,實際使用感受很是給力。express

除了稍微修改一下依賴,其餘基本沒動。框架
ts 給個人第一印象就是清爽分明,配合WebStorm逆天的自動編譯,寫的過程當中代碼哪邊編譯不經過提示很是詳細。異步
先貼兩段代碼:mongoose
serviceBase.ts函數
/** * Created by trump on 15/4/23. */ ///<reference path="../_references.d.ts"/> /// <reference path="./_references.d.ts"/> import db = require('../db/db'); import Future = require("fibers/future"); import Fiber = require('fibers'); export class ServiceBase { constructor(table) { this.table = table; // 這個table就是mongoose的Model this.$table = Future.wrap(table); //配合node fibber 解決異步callback hell 太給力了 } table; $table; getAll() : IFuture<any> { return this.$table.findFuture.bind(this.table)({}); } add(model): IFuture<any> { return this.$table.createFuture.bind(this.table)(model); } findById(id: string): IFuture<any> { return this.$table.findOneFuture.bind(this.table)({ _id: id }); } find(query:any): IFuture<any>{ return this.$table.findFuture.bind(this.table)(query); } findOne(query:any): IFuture<any>{ return this.$table.findOneFuture.bind(this.table)(query); } }
documentServices.tspost
1 /// <reference path="./_references.d.ts"/> 2 import db = require('../db/db'); 3 4 import Future = require("fibers/future"); 5 import Fiber = require('fibers'); 6 import sb = require('./servicesBase'); 7 8 export class Document extends sb.ServiceBase { 9 10 constructor($db) { 11 super( $db.Document ); 12 this.db = $db; 13 } 14 15 db; 16 17 getList() : IFuture<any> { 18 return this.getAll(); 19 } 20 21 } 22 23 $injector.register('documentServices', Document); // 眼尖的同窗會看到這行代碼,沒錯這邊將DocumentService注入到容器裏面,在接下來的controller中咱們就不須要require DocumentService 這個類寫一對的路徑了
controller/api.ts
///<reference path="../_references.d.ts"/> import express = require('express'); import services = require('../../services/documentServices'); class Controller { constructor($documentServices) { this.services = $documentServices; // 咱們這邊只須要在構造函數裏面指定好依賴的名稱,yok框架就幫咱們作好一切了 } services;// = <services.Document>$injector.resolve('documentServices'); 'get/:name'(req:express.Request, res:express.Response) { (()=> { var doc = this.services.findOne({ name: req.params.name }).wait(); res.send(doc||{}); }).future()(); } '[post]edit'(req:express.Request, res:express.Response) { (()=> { var saved = null; if(!req.body._id) { saved = this.services.add({ name: req.body.name , content: req.body.content }).wait(); res.send(saved); } else { saved = this.services.findById(req.body._id).wait(); saved.content = req.body.content; saved.name = req.body.name; saved.save(function(){ res.send(saved); }); } }).future()() } rename(req:express.Request, res:express.Response) { } remove(req, res) { } } $injector.register('apiHomeController', Controller); module.exports = $injector.resolve('apiHomeController');
整體來講:
TypeScript 開發很給力,
NativeScript的那套依賴注入也很給力。
