不论基于不论什么语言开发内部项目，我们常常会在内部封装一些极具通用性的功能模块。假设我们认为该通用模块对其他团队有可取之处，全然能够将其开源出去。
npm就是公布nodejs程序包的最优工具。
1. 首先在npmjs.org注冊一个账号：（可省）
2. 通过npm adduser来注冊新账号或登录老账号：
[root@~/wade/nodejs/pv-tj]# npm adduser Username: billfeller Password: Email: (this IS public) 531958936@qq.com
3. 在本地通过npm init完毕对应的模块的开发，请注意在main文件里规范对外暴露的接口，注意。关于npm init的使用方法请參考之前的文章，这里不再具体说明：
4. 完毕模块开发后就能够通过npm publish打包公布对应的程序包：
[root@~/wade/nodejs/uv-tj]# npm publish + uv-tj@1.0.0
关于npm publish的使用请见：
5. 此时你应该能够在npmjs.org上查到uv-tj包：
6. 接下来就能够像使用其他包一样使用uv-tj包了：
[root@~/wade/nodejs]# git clone git@github.com:billfeller/uv-tj-demo.git Initialized empty Git repository in /root/wade/nodejs/uv-tj-demo/.git/ remote: Counting objects: 5, done. remote: Compressing objects: 100% (4/4), done. remote: Total 5 (delta 0), reused 0 (delta 0) Receiving objects: 100% (5/5), done. [root@~/wade/nodejs]# cd uv-tj-demo/ [root@~/wade/nodejs/uv-tj-demo]# npm init This utility will walk you through creating a package.json file. It only covers the most common items, and tries to guess sane defaults. See `npm help json` for definitive documentation on these fields and exactly what they do. Use `npm install <pkg> --save` afterwards to install a package and save it as a dependency in the package.json file. Press ^C at any time to quit. name: (uv-tj-demo) version: (1.0.0) description: entry point: (index.js) test command: git repository: (https://github.com/billfeller/uv-tj-demo.git) keywords: uv tj module demo author: billfeller license: (ISC) MIT About to write to /root/wade/nodejs/uv-tj-demo/package.json: { "name": "uv-tj-demo", "version": "1.0.0", "description": "uv-tj-demo ==========", "main": "index.js", "scripts": { "test": "echo "Error: no test specified" && exit 1" }, "repository": { "type": "git", "url": "https://github.com/billfeller/uv-tj-demo.git" }, "keywords": [ "uv", "tj", "module", "demo" ], "author": "billfeller", "license": "MIT", "bugs": { "url": "https://github.com/billfeller/uv-tj-demo/issues" }, "homepage": "https://github.com/billfeller/uv-tj-demo" } Is this ok? (yes) yes [root@~/wade/nodejs/uv-tj-demo]# vim package.json [root@~/wade/nodejs/uv-tj-demo]# npm i uv-tj --save uv-tj@1.0.0 node_modules/uv-tj ├── redis@0.12.1 └── express@4.10.2 (utils-merge@1.0.0, merge-descriptors@0.0.2, fresh@0.2.4, cookie@0.1.2, escape-html@1.0.1, range-parser@1.0.2, cookie-signature@1.0.5, finalhandler@0.3.2, vary@1.0.0, media-typer@0.3.0, methods@1.1.0, parseurl@1.3.0, serve-static@1.7.1, content-disposition@0.5.0, path-to-regexp@0.1.3, depd@1.0.0, qs@2.3.2, etag@1.5.0, on-finished@2.1.1, debug@2.1.0, proxy-addr@1.0.3, send@0.10.1, accepts@1.1.3, type-is@1.5.3) [root@~/wade/nodejs/uv-tj-demo]# vim index.js [root@~/wade/nodejs/uv-tj-demo]# npm start > uv-tj-demo@1.0.0 start /root/wade/nodejs/uv-tj-demo > node index.js
此时通过浏览器訪问：
完整代码请见：
7. 也能够直接git clone https://github.com/billfeller/uv-tj-demo到本地，直接运行npm install来測试：
[root@~/wade/test]# git clone https://github.com/billfeller/uv-tj-demo Initialized empty Git repository in /root/wade/test/uv-tj-demo/.git/ remote: Counting objects: 9, done. remote: Compressing objects: 100% (7/7), done. remote: Total 9 (delta 1), reused 4 (delta 0) Unpacking objects: 100% (9/9), done.
