How to use Angular to launch a component

This time I will show you how to use Angular to launch a component. What are the precautions for using Angular to launch a component? The following is a practical case, let's take a look.

Create module

Initialize package.json file

Execute naming

npm init -y

The package.json file will be automatically generated as follows, name The default is the folder name

{
 "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"
}

On this basis, you can set the default generated value

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

Delete and try again

{
 "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"
}

Then add a README.md file

Briefly introduce the project

# MZC-Ng-Api
这是一个npm包发布测试项目
## License
请查看 [MIT license](./LICENSE).

Add an open source agreement file

You still have to have a nose and an eye to do things.

MIT License

本项目为测试项目，完全免费。

Add source code

Create a src directory and add an Index.ts file

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

Create an Index.ts file

export * from './src/index'

Compile using typescript

If you don’t have typescript installed, install it first

npm i -g typescript

Initialize the tsconfig.json file

tsc --init

Automatically generate the file, very complete and powerful , and explanation

}

Compilation

tsc -p .

Successful compilation will generate a js file

Release

Although there is nothing, there is everything.

Modify package.json file

{
 "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",

}

Correct download source

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

Login

npm login

If not Just register an account

Publish

npm publish

It will take effect immediately after the publication is completed. You can check it by going to npm and download it

Use

Create a new project installation package

npm i mzc-ng-api

I found that many things have been published.

And there are no smart prompts during development work.

Perfect optimization

Generate header files when compiling, *.d.ts.

Solve the compiler prompt function

Set in tsconfig.json

"declaration": true,

You can study more about tsconfig.json configuration Research

Specify release file

Update version

npm version prepatch

More operations

# 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

Download It will be much better if you come down and take a look

Encapsulate some scripts.

You can write more quick scripts according to your own needs

 "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"
 },
