使用typescript开发angular模块并发布npm包

作者：易兒善

本篇文章主要介绍了使用typescript开发angular模块并发布npm包，小编觉得挺不错的，现在分享给大家，也给大家做个参考。一起跟随小编过来看看吧

本文介绍了使用typescript开发angular模块并发布npm包，分享给大家，具体如下：

创建模块

初始化package.json文件

执行命名

npm init -y

会自动生成package.json文件如下，name默认为文件夹名称

{
 "name": "MZC-Ng-Api",
 "version": "1.0.0",
 "description": "",
 "main": "index.js",
 "scripts": {
  "test": "echo \"Error: no test specified\" && exit 1"
 },
 "keywords": [],
 "author": "",
 "license": "ISC"
}

在此基础上可以设置默认生成值

npm config set init-author-name "yiershan"       # 你的名称
npm config set init-author-email "511176294@qq.com" # 你的邮箱
npm config set init-author-url "https://www.jianshu.com/u/8afb7e623b70" # 你的个人网页
npm config set init-license "MIT"          # 开源授权协议名
npm config set init-version "0.0.1"             # 版本号

删掉重新来一遍

{
 "name": "MZC-Ng-Api",
 "version": "0.0.1",
 "description": "",
 "main": "index.js",
 "scripts": {
  "test": "echo \"Error: no test specified\" && exit 1"
 },
 "keywords": [],
 "author": "yiershan <511176294@qq.com> (https://www.jianshu.com/u/8afb7e623b70)",
 "license": "MIT"
}

然后添加一个 README.md 文件

简单介绍下项目

# MZC-Ng-Api

这是一个npm包发布测试项目

## License

请查看 [MIT license](./LICENSE).

添加一个开源协议文件

做事情还是要做的有鼻子有眼的嘛。

MIT License

Copyright (c) 2017 MZC

本项目为测试项目，完全免费。

添加源码

创建一个src目录并添加一个Index.ts文件

export class MzcNgApi{
  private name: string;
  constructor() {
    this.name = "MzcNgApi";
  }
}

创建一个Index.ts文件

export * from './src/index'

使用typescript编译

没有安装typescript就先安装

npm i -g typescript

初始化tsconfig.json文件

tsc --init

自动生成文件,很全很强大，还有解释

  /* Basic Options */

  // "isolatedModules": true,        /* Transpile each file as a separate module (similar to 'ts.transpileModule'). */

  /* Strict Type-Checking Options */
  "strict": true,              /* Enable all strict type-checking options. */
  // "noImplicitAny": true,         /* Raise error on expressions and declarations with an implied 'any' type. */

  // "preserveSymlinks": true,       /* Do not resolve the real path of symlinks. */

  /* Source Map Options */
  // "sourceRoot": "./",          /* Specify the location where debugger should locate TypeScript files instead of source locations. */
  // "mapRoot": "./",            /* Specify the location where debugger should locate map files instead of generated locations. */
  // "inlineSourceMap": true,        /* Emit a single file with source maps instead of having a separate file. */

  /* Experimental Options */
  // "experimentalDecorators": true,    /* Enables experimental support for ES7 decorators. */
  // "emitDecoratorMetadata": true,     /* Enables experimental support for emitting type metadata for decorators. */
 }
}

编译

tsc -p .

编译成功会生成了js文件

发布

虽然什么都没有，但是什么都有了。

修改package.json文件

{
 "name": "mzc-ng-api", // 这个名字要小写且不能重复，有大写字母会报错
 "version": "1.0.2",
 "description": "个人博客系统，从后台api取数据的angular封装",
 "main": "index.js",
 "scripts": {
  "test": "echo \"Error: no test specified\" && exit 1"
 },
 "repository": {
  "type": "git",
  "url": "git+https://github.com/yiershan/MZC-Ng-Api.git"
 },
 "keywords": [],
 "author": "yiershan <511176294@qq.com> (https://www.jianshu.com/u/8afb7e623b70)",
 "license": "MIT",
 "bugs": {
  "url": "https://github.com/yiershan/MZC-Ng-Api/issues"
 },
 "homepage": "https://github.com/yiershan/MZC-Ng-Api#readme"
}

修正下载源

npm config set registry https://registry.npmjs.org/

登录

npm login

如果没有账号就去注册一个吧

发布

npm publish

发布完成立即生效，去npm就能查到并可以下载

使用

新建一个项目安装包

npm i mzc-ng-api

发现很多东西都发布上去了。

而且在开发工作没有智能提示。

完善优化

编译时生成头文件，*.d.ts。

解决编译器提示功能

在tsconfig.json种设置

"declaration": true,

关于tsconfig.json的更多配置可以好好研究研究

指定发布文件

修改

{
 "name": "mzc-ng-api",
 "version": "1.0.2",
 "description": "个人博客系统，从后台api取数据的angular封装",
 "main": "index.js",
 "types": "./index.d.ts", // 添加这个
 "scripts": {
  "test": "echo \"Error: no test specified\" && exit 1"
 },
 "files": [ // 指定发布文件
  "index.js",
  "index.d.ts",
  "src/*.js",
  "src/*.d.ts",
  "src/**/*.js",
  "src/**/*.d.ts",
  "README.md",
  "LICENSE",
  "package.json"
 ],
 "repository": {
  "type": "git",
  "url": "git+https://github.com/yiershan/MZC-Ng-Api.git"
 },
 "keywords": [],
 "author": "yiershan <511176294@qq.com> (https://www.jianshu.com/u/8afb7e623b70)",
 "license": "MIT",
 "bugs": {
  "url": "https://github.com/yiershan/MZC-Ng-Api/issues"
 },
 "homepage": "https://github.com/yiershan/MZC-Ng-Api#readme"
}

更新版本

npm version prepatch

更多操作

# 版本号从 1.2.3 变成 1.2.4-0，就是 1.2.4 版本的第一个预发布版本。
npm version prepatch

# 版本号从 1.2.4-0 变成 1.3.0-0，就是 1.3.0 版本的第一个预发布版本。
npm version preminor

# 版本号从 1.2.3 变成 2.0.0-0，就是 2.0.0 版本的第一个预发布版本。
npm version premajor

# 版本号从 2.0.0-0 变成 2.0.0-1，就是使预发布版本号加一。
npm version prerelease
更新

npm publish

下载下来看看就好多了

封装些脚本。

可以根据自己需求编写更多快捷脚本

 "scripts": {
  "build": "tsc -p .",
  "b":"npm run build",
  "version": "npm version prerelease",
  "v":"mpm run v",
  "publish": "npm run b && npm publish",
  "p":"npm run publish"
 },

至此基本的流程算是走通了。
