在github创建一个项目,比如创建名为randomNickname的项目,
这个代码库用户存放npm插件的代码。
首先在npm官网申请账号,后面提交到npm官网需要用到。
mkdir npmjs
cd npmjs
npm init
根据提示输入相应的信息,可用参考如下设置。
ubuntuvimdeMacBook-Pro:randomNichname ubuntuvim$ npm init
This utility will walk you through creating a package.json file.
It only covers the most common items, and tries to guess sensible 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.

About to write to /Users/ubuntuvim/codes/my-npm-plugins/randomNichname/package.json:

Is this ok? (yes) yes
ubuntuvimdeMacBook-Pro:randomNichname ubuntuvim$
创建完成package.json之后你也可以根据实际情况做修改。
创建npm插件所需的目录和文件,目录结构如下:
npmjs
├─┬ lib
│ └── npmjs.js
├─┬ test
│ └── test.js
├── .gitignore
├── .npmignore
├── .travis.yml
├── index.js
├── LICENSE
├── makefile
├── package.json
├── README.md
这些文件的作用是:
- lib目录下存放业务逻辑文件
- test目录下存放单元测试用例
- .npmignore记录哪些文件不需要被发布到npmjs.org
- .travis.yml是持续集成服务travis的描述文件
- index.js是入口文件
- makefile方便我们用make test进行测试
- README.md是此module的描述和使用方法
编写插件代码
主要代码直接放在index.js
。比如本插件是用于获取随机的三国人物名称,代码如下(详细代码请从github下载):
// 从1099个名字中获取任意名字
(function () {
'use strict';
// 一共1099个
var arr = [];
// 获取随机名字
function getNickname() {
// 取0~1099的随机数
var random = Math.floor(Math.random() * 1099);
if (random >= 1099)
throw new Error("获取人名数组下标月结!");
return arr[random];
}
exports.getNickname = getNickname;
}());
测试
var arr = require('../index');
var s = arr.getNickname();
if (s) {
console.log(s);
} else {
throw new Error('The test does not pass...');
}
运行测试。
node ./test/test.js
在LICENSE文件中添加许可信息
许可内容请从github下载。
编写使用文档README.md
插件使用方式
-
安装插件
npm install randomNickname
-
使用插件
var names = require('randomNickname');
var s = names.getNickname();
console.log('得到的人物名字为: ' + s);
提交代码到github
步骤如下:
git init
git remote add origin <git远程URL>
git add *
git commit -am '描述信息'
git push origin master
如果出现类似如下错误
! [rejected] master -> master (non-fast-forward)
error: failed to push some refs to 'https://github.com/ubuntuvim/randomNickname.git'
hint: Updates were rejected because the tip of your current branch is behind
hint: its remote counterpart. Integrate the remote changes (e.g.
hint: 'git pull ...') before pushing again.
hint: See the 'Note about fast-forwards' in 'git push --help' for details.
先更新合并再提交到远程代码库。
git pull
git merge origin/master
git push origin/master
发布到npmjs官网
步骤如下:
npm adduser
(输入你在npmjs官网注册的账号和密码)npm publish .
如果出现错误:
no_perms Private mode enable, only admin can publish this module
执行下列代码重置后再执行npm adduser
、npm publish .
。
npm config set registry http://registry.npmjs.org
等待完成,看到如下信息说明发布成功。
+ randomnickname@0.1.0
如果你的代码修改了又需要重新发布到npmjs上,则首先修改package.json
里的版本号,再执行npm publish .
即可。
此时你可以到npmjs的个人中心中查看刚刚发布的插件。 比如我的个人中心https://www.npmjs.com/~ubuntuvim。
