一、注册npm账号
前往https://www.npmjs.com注册一个账号。
二、制作npm包
1.建立一个仓库,这里以cat-jsutils为例
这里需要注意下名称,因为如果被占用,无法使用npm install直接安装。
判断是否被占用,可使用npm search xxx来判断
未占用
cenghaihandeMacBook-Pro:cat-jsutils catchzeng$ npm search cat-jsutils
No matches found for "cat-jsutils"
已占用
cenghaihandeMacBook-Pro:cat-jsutils catchzeng$ npm search jsutils

2.Clone仓库到本地 & cd到cat-jsutils,执行npm init
cenghaihandeMacBook-Pro:Github catchzeng$ cd cat-jsutils/
cenghaihandeMacBook-Pro:cat-jsutils catchzeng$ 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 ` afterwards to install a package and
save it as a dependency in the package.json file.
Press ^C at any time to quit.
package name: (cat-jsutils)
version: (1.0.0)
description: js utils
entry point: (index.js)
test command:
git repository: (https://github.com/CatchZeng/cat-jsutils)
keywords: util utils js javascript node utility utilities
author: CatchZeng
license: (ISC) MIT
About to write to /Users/catchzeng/Documents/Code/Github/cat-jsutils/package.json:
{
"name": "cat-jsutils",
"version": "1.0.0",
"description": "js utils",
"main": "index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1"
},
"repository": {
"type": "git",
"url": "git+https://github.com/CatchZeng/cat-jsutils.git"
},
"keywords": [

"bugs": {
"url": "https://github.com/CatchZeng/cat-jsutils/issues"
},
"homepage": "https://github.com/CatchZeng/cat-jsutils#readme"
}
3.新建index.js【根据上一步的entry point: (index.js)指定】,组织代码结构,这里以cat-jsutils为例
//number.js
function isNum(value) {
return (typeof value === 'number') && !isNaN(parseFloat(value)) && isFinite(value);
}
module.exports = {
isNum,
}
//string.js
function isString(value) {
return typeof value === 'string' || value instanceof String;
}
...
...
module.exports = {
isString,
contains,
containsAny,
containsAll,
};
//index.js
var utils = {};
utils.string = require('./src/string');
utils.number = require('./src/number');
module.exports = utils;
4.在package.json中指定版本号,并提交代码到github上
{
"name": "cat-jsutils",
"version": "1.0.1",
"description": "js utils",
"main": "index.js",
...
}
三、发布npm包
到项目跟目录下,执行publish命令
cenghaihandeMacBook-Pro:cat-jsutils catchzeng$ npm publish
+ [email protected]
cenghaihandeMacBook-Pro:cat-jsutils catchzeng$
发布成功后就可以在https://www.npmjs.com上看到自己的项目
四、更新版本
更新package.json中的版本号,并提交代码到github上,重新publish npm包即可
{
"name": "cat-jsutils",
"version": "1.0.2",
"description": "js utils",
"main": "index.js",
...
}
cenghaihandeMacBook-Pro:cat-jsutils catchzeng$ npm publish
+ [email protected]
cenghaihandeMacBook-Pro:cat-jsutils catchzeng$
五、变优雅
何为优雅,先看下express这个仓库比我们自己的仓库优雅在哪里
1.Logo
这么吗,我不是设计师,有美感的朋友自己设计一个吧,这里我随便做一个了。
2.npm version badge
增加这个其实只要在README中增加
[![NPM version](https://img.shields.io/npm/v/仓库名.svg)](https://www.npmjs.com/package/仓库名)
以cat-jsutils为例子
[![NPM version](https://img.shields.io/npm/v/cat-jsutils.svg)](https://www.npmjs.com/package/cat-jsutils)
3.CI状态
关于持续集成理论部分,可以看之前的文章持续集成 -- 理论篇。一般开源项目会选用travis-ci。
使用github账号登录travis-ci,然后打开需要持续集成的项目
在项目中增加.travis.yml文件,用于配置持续集成的构建步骤。这里以cat-jsutils为例,里面只执行了单元测试
language: node_js
node_js:
- stable
script: npm run test
说明:cat-jsutils的测试使用的是mocha+chai+istanbul,详见package.json
{
"name": "cat-jsutils",
"version": "1.0.1",
"description": "js utils",
"main": "index.js",
"scripts": {
"test": "mocha",
"coverage": "istanbul cover _mocha -- -R spec --timeout 5000 --recursive",
"coverage:check": "istanbul check-coverage"
},
"repository": {
"type": "git",
"url": "git+https://github.com/CatchZeng/cat-jsutils.git"
},
"keywords": [
"util",
"utils",
"js",
"javascript",
"node",
"utility",
"utilities"
],
"author": "CatchZeng",
"license": "MIT",
"bugs": {
"url": "https://github.com/CatchZeng/cat-jsutils/issues"
},
"homepage": "https://github.com/CatchZeng/cat-jsutils#readme",
"devDependencies": {
"chai": "^4.1.2",
"istanbul": "^0.4.5",
"mocha": "^5.1.0"
}
}
提交.travis.yml后变会触发构建,可以到travis-ci查看构建过程。
点击构建成功的图标就会弹出地址
将该地址放到README上即可。以cat-jsutils为例子
[![travis ci](https://api.travis-ci.org/CatchZeng/cat-jsutils.svg?branch=master)](https://travis-ci.org/CatchZeng/cat-jsutils)
4.测试覆盖率
显示测试覆盖率,我们需要借助coveralls。
同样的使用github账户登录coveralls,然后开启对应的项目
点击details,查看repo_token并复制,后面会使用到。
安装coveralls
npm i coveralls -D
安装travis
gem install travis
执行encrypt,COVERALLS_TOKEN就是刚才复制的repo_token
travis encrypt COVERALLS_TOKEN=JGOXXXXXXXXXXXXXqKVJ --add
执行之后会发现.travis.yml下多出env,这个环境变量能帮助我们将测试覆盖率安全上传到coveralls
env:
global:
- secure: 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
加入cover脚本
"cover": "istanbul cover --report lcov node_modules/mocha/bin/_mocha -- -R spec test/*.js"
看下最后的.travis.yml文件和 package.json
language: node_js
node_js:
- stable
script: npm run test
after_script: npm run cover && cat coverage/lcov.info | node_modules/coveralls/bin/coveralls.js
env:
global:

}
}
5.小结
至此,我们完成了提交代码-》travis-》mocha单元测试-》istanbul覆盖率-》coveralls-》github显示npm版本、ci、覆盖率状态。
6.README
完善的README会让开源变得更加优雅。
加入Installation、Usgae、API等描述能帮助使用者更会上手,详细请参考README.md。
六、总结
本文从npm包的制作、发布到优化,讲述了如何较好地开源npm包,当然还有需要不足。欢迎感兴趣的朋友一起讨论、优化。
