初始化

新建文件夾
初始化命令

  npm init -ytsc --initnpm i @types/nodenpm i typescript# 處理別名npm i -D tsc-alias

-y 表示選項都為yes
安裝ts相關依賴

在這里插入圖片描述

新建相關文件

bin 文件夾
src文件夾
- commands 文件夾（命令
- utils 文件夾 (封裝方法）
  - index.ts文件
```
export * from "./chalk"
```
- index.ts 文件
```
#! /usr/bin/env node
console.log('hello gaogao')
```
  #! /usr/bin/env node
  前后不可有空格
  #!用于指定腳本的解釋程序，開發(fā)npm包這個指令一定要加
.gitignore 文件

	#basicnode_modulepackage-lock.json#buildbin

.npmrc 文件

	registry=https://mirrors.huaweicloud.com/repository/npm

TS配置

建【tsconfig.json】

{"compilerOptions": {"target": "ES6","module": "commonjs","outDir": "./bin", // 輸出地址 相對路徑"baseUrl": "./","strict": true,"moduleResolution": "node","esModuleInterop": true,"skipLibCheck": true,"forceConsistentCasingInFileNames": true,"resolveJsonModule": true,"paths":{"@":["src"],"@utils":["utils"],}},"include": ["./src","src/**/*.ts","src/**/*.d.ts"]
}

修改【package.json】

bin:執(zhí)行的文件或命令
scripts-build 處理ts文件

{"name": "gaogao-cli","version": "1.0.0","description": "","main": "index.js","scripts": {"test": "echo \"Error: no test specified\" && exit 1","build": "tsc && tsc-alias"},"bin": {"gaogao": "/bin/src/index.js"},"keywords": [],"author": "","license": "ISC","dependencies": {"@types/figlet": "^1.7.0","@types/fs-extra": "^11.0.4","@types/inquirer": "^9.0.7","@types/log-symbols": "^3.0.0","@types/node": "^22.13.2","@types/shelljs": "^0.8.15","chalk": "^4.0.0","commander": "^9.0.0","download-git-repo": "^3.0.2","figlet": "^1.8.0","fs-extra": "^10.0.1","inquirer": "^8.2.1","loading-cli": "^1.1.2","log-symbols": "^4.1.0","ora": "^5.4.1","shelljs": "^0.8.5","table": "^6.9.0","typescript": "^5.7.3"},"devDependencies": {"tsc-alias": "^1.8.10"}
}

測試

ts語言需要先build

npm run build

build后bin文件夾下自動新增index.js文件
驗證修改是否生效都需要build

安裝相關工具

安裝固定版本，有些版本會有bug

commander

https://www.npmjs.com/package/commander

處理控制臺命令工具
解析用戶輸入時一些參數(shù)
- 例如 create 就是利用此工具做解析輔助

cnpm i commander@9.0.0

import {program} from 'commander'
import Pack from "../package.json"
program.version(Pack.version, "-v, --version");
program.parse(process.argv)//nodejs提供的屬性

封裝常用命令

commands文件夾下新建create文件夾 文件

import commandCreate from'./create'
// create見 create命令目錄
const commands:any = {'create <project-name>':{description:'create a project',option:[{cmd:'-f,--force',msg:'overwrite target directory if it exists'}],action:commandCreate}
}export default commands

import { Command } from "commander";
import Commands from "@commands";
//index.ts
Object.keys(Commands).forEach((command:any) => {const current:any = program.command(command);if (Commands[command].option && Commands[command].option.length) {let options = current.optionCommands[command].option.forEach((item: { cmd: string; msg: any }) => {current.option(item.cmd, item.msg || "");});}current.action(Commands[command].action);
});

chalk 美化工具

該模塊用于添加顏色和樣式到控制臺輸出

效果見【figlet】

import chalk from 'chalk'
console.log("\r\n" + chalk.greenBright.bold('hello gaogao-cli'))

封裝字體處理

import chalk from 'chalk';
export const Cblue= (text:string) =>chalk.blue(text)
export const Cred= (text:string) =>chalk.red(text)
export const Cgreen= (text:string) =>chalk.green(text)

figlet

https://www.npmjs.com/package/figlet

該模塊用于生成ASCII藝術字

具體字體可以去figlet官網(wǎng)查看

cnpm i figlet@1.5.2 @types/figlet

import chalk from 'chalk'
import figlet from 'figlet'
program.name("gaogao").description("gaogao-cli").usage("<command> [options]")// 用在內(nèi)置的幫助信息之后輸出自定義的額外信息.on("--help", () => {console.log("\r\n" + chalk.greenBright.bold(figlet.textSync("gaogao-cli", {font: "Standard",horizontalLayout: "default",verticalLayout: "default",width: 100,whitespaceBreak: true,})))console.log(`\r\n Run ${chalk.cyanBright(`gaogao-cli <command> --help`)} for detailed usage of given command.`)});

inquirer -命令行交互工具

https://www.npmjs.com/package/inquirer

該模塊用于實現(xiàn)交互式命令行界面
- 例如vue詢問是否單元測試

cnpm i inquirer@8.2.1 @types/inquirer

在這里插入圖片描述

封裝inquirer

- lib文件夾下`新建interactive.ts `文件

import inquirer from 'inquirer';/*** @param {string} message 詢問提示語句* @returns {Object} 根據(jù)name屬性獲取用戶輸入的值{confirm: y/n}*/
export const inquirerConfirm = async (message:string): Promise<object> => {const answer = await inquirer.prompt({type: "confirm",name: "confirm",message,});return answer;
}/*** * @param {string} name 詢問事項* @param {string} message 詢問提示語句* @param {Array} choices 選擇模板列表，默認讀取對象的name屬性* @returns {Object} 根據(jù)name屬性獲取用戶輸入的值{請選擇項目模板: xxxxxx}*/
export const inquirerChoose = async (name:string,message:string, choices:Array<any>): Promise<any> => {const answer = await inquirer.prompt({type: 'list',name,message,choices,});return answer;
}/*** @param {Array} messages  詢問提示語句數(shù)組* @returns {Object} 結果對象*/
export const inquirerInputs = async (messages: Array<any>): Promise<object> => {const questions = messages.map(msg => {return {name: msg.name,type: "input",message: msg.message,}})const answers = await inquirer.prompt(questions);return answers
}

loading-cli

https://www.npmjs.com/package/loading-cli

utils 下新建loading文件
在這里插入代碼片

//loading.ts
import loading, { Options, Loading } from "loading-cli";class Load {load: null | Loading;constructor() {this.load = null;}/*** @Descripttion: 開始loading狀態(tài)* @msg: * @param {Options} options* @return {*}*/  start  (options: Options | string) {if(!this.load){typeof options==='object'&&!options.frames&&(options.frames=['<','<','^','>','>','_','_'])this.load = loading(options).start()}else{this.load.start(options as string)}};stop () {this.load && this.load.stop();};succeed(text='success') {this.load && this.load.succeed(text);};warn(text: string) {this.load && this.load.warn(text);};info (text: string){this.load && this.load.info(text);};
}export default new Load();

// index.tsprogram.command("loading").description("View all available templates").action(() => {loading.start({color: "red",text: "begin",});setTimeout(() => {loading.warn("警告");setTimeout(() => {loading.info("提示");setTimeout(() => {loading.stop();}, 2000);}, 2000);}, 2000);})

在這里插入圖片描述

fs

https://url.nodejs.cn/api/fs.html

該模塊用于對文件系統(tǒng)進行更強大的操作。

cnpm i fs-extra@10.0.1  @types/fs-extra

封裝文件處理方法

import fs from "fs";import { Cred } from "./chalk";export const readDir = (path: string): Promise<any> =>new Promise((res, rej) => {fs.readdir(path, (err) => {if (!err) res(true);res(false)});});export const mkdir = (path: string): Promise<any> =>new Promise((res, rej) => {fs.mkdir(path, (err) => {if (!err) res("");rej(`${Cred("Can not mak dir")} ${typeof err === "string" ? err : JSON.stringify(err)}`);});});export const rm = (path: string): Promise<any> =>new Promise((res, rej) => {fs.rm(path,{ recursive: true}, (err) => {if (!err) res("");rej(`${Cred("Can not remove dir："+ path)} ${typeof err === "string" ? err : JSON.stringify(err)}`);});});

/*** 項目模板列表*/
export const templates = [{name: "vue-template",value: "direct:https://gitee.com/賬號/vue-template.git",desc: "基于vite的自定義vue項目模板",},
