npm包的制作与发布使用

制作npm包的步骤

1. 注册npm账户

   1 2	npm adduser

   或者登陆npm官网注册

2. 登陆npm账户

   1 2

   npm login

3. 编写npm包

   • 初始化package.json并配置

   1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25

   npm init ``````json { "name": "包名", "version": "版本号", "description": "描述", "main": "入口文件", "scripts": { "test": "配置测试" }, // 配置git仓库 "repository": { "type": "git", "url": "git仓库地址" }, "keywords": [ "关键字" ], "author": "", "license": "MIT", "dependencies": { } }

4. 发布

   1 2 3 4

   npm publish # 指定标签beta npm publish --tag beta

5. 删除

   1 2	npm unpublish --force 包名

6. 命令行工具包的制作

   1 2 3 4 5 6 7 8 9 10 11

   { "name": "工具名称", "version": "版本号", "description": "描述", "bin": { "命令名称": "命令入口文件" }, "author": "zengyuwen", "license": "MIT" }

   代码编写

   1 2 3 4

   #!/usr/bin/env node // 获取命令行参数 const arguments = process.argv.splice(2);

代码示例

命令行工具

• package.json

  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

  { "name": "cli", "version": "1.0.0", "description": "", "main": "index.js", "scripts": { "test": "echo \"Error: no test specified\" && exit 1" }, "bin": { "my-cli": "./index.js" }, "author": "", "license": "ISC" }

• index.js

  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40

  #!/usr/bin/env node // 获取命令行参数 const arguments = process.argv.splice(2); // 参数解析成数组 function parse(arguments) { return arguments.map(function(value) { if (/^-+/.test(value)) { return value.replace(/^-+/, ''); } return value; }); } // 参数解析成键值对 function parseObj(arguments) { let result = []; for (let i = 0;i < arguments.length; i+= 2) { tmp = {}; if ((i + 1) >= arguments.length) { tmp[arguments[i].replace(/^-+/, '')] = null; } else { tmp[arguments[i].replace(/^-+/, '')] = arguments[i+1]; } result.push(tmp); } return result; } // 求和 function add(arguments) { var params = parse(arguments); var result = 0; for (let i of params) { if (/^[0-9]{1,}$/.test(i)) { result += parseInt(i); } } return result; } console.log(parseObj(arguments)); console.log(add(arguments));
