一、TypeScript简介
1.定义
(1)Typescript = JavaScript + type + ( some other stuff )
(2)Typescript需要先被编译成Javascript,而后才能使用
2.demo
安装typescript:
index.ts:
var fn = () => ‘response’
command line:
tsc init
修改tsconfig.json的outDir和rootDir,并增添out目录与src目录
修改package.json的scripts为"start": "tsc && node out/index.js"
运行npm start
结果如下:
此时,src里的index.ts已经被编译至index.js中
index.js:
var fn = function () { return ‘response’; }
二、项目实现
1.需求
在node环境下,使用ts语言,借用gituhub的api实现对用户的关键信息查询功能
2.目录
3.安装库
(1)request库
npm i @types/request --save-dev npm i request –save
(2)lodash库(用于排序)
npm i @types/lodash --save-dev npm install lodash --save-dev
4.内容
index.ts
import { GithubApiService } from ‘./GithubApiService‘ import { User } from ‘./User‘ import { Repo } from ‘./Repo‘; import * as ld from ‘lodash‘; // node.js内置功能,用于获取第三个参数内容 console.log(process.argv[2]) let svc: GithubApiService = new GithubApiService(); if (process.argv.length < 3) { console.log("请输入用户名"); } else { svc.getUserInfo("bbcfive", (user: User) => { svc.getRepos(user.login, (repos: Repo[]) => { // 按照fork的数量由小到大排列 ps:返回值 * -1 代表由大到小排列 let sortedRepos = ld.sortBy(repos, [(repo: Repo) => repo.forks_count]); user.repos = sortedRepos; console.log(user); }) }); }
GithubApiService.ts
import * as request from ‘request‘ import { User } from ‘./User‘; import { Repo } from ‘./Repo‘; const options = { headers: { ‘User-Agent‘: ‘request‘ }, json: true } export class GithubApiService { getUserInfo(userName:string, callBack: (user: User) => any) { request.get("http://api.github.com/users/" + userName, options, (error: any, response: any, body: any) => { // 写法一 // let user = new User(JSON.parse(body)); // typeof body == object // 写法二 let user: User = new User(body); // typeof body == string callBack(user); }) } getRepos(userName:string, callBack: (repos: Repo[]) => any) { request.get("http://api.github.com/users/" + userName + "/repos", options, (error: any, response: any, body: any) => { let repos: Repo[] = body.map((repo: any) => new Repo(repo)); callBack(repos); }) } }
Repo.ts
export class Repo { name: string; description: string; url: string; size: number; forks_count: number; constructor (repo: any) { this.name = repo.name; this.description = repo.description; this.url = repo.html_url; this.size = repo.size; this.forks_count = repo.forks_count; } }
User.js
import { Repo } from ‘./Repo‘; export class User { login: string; fullName: string; repoCount: number; followerCount: number; repos: Repo[] = []; constructor (userResponse: any) { this.login = userResponse.login; this.fullName = userResponse.name; this.repoCount = userResponse.public_repos; this.followerCount = userResponse.followers; } }
5.运行
因为在index.ts里已经使用nodeJs自带的api,process.argv对npm输入命令做了判断,所以只需要在命令行输入
npm start bbcfive // "bbcfive"是我的github用户名
终端打印结果:
可以清晰的看到此用户的github关键信息。
三、其他延展功能
给定一定量的github用户名列表,可以通过此方法循环获取每个用户的关键信息,并作筛选,来获得目标范围用户。
适用于以下场景:
1.hr招人
2.找一些很赞的项目
3.社交(毕竟是全球最大的同性交友网站~~)
—— 完 ——
TypeScript + node.js + github.api, 实现github快速找到目标用户
