本文简单地记录了发布一个简单 npm 包的过程，以便后续参考使用。

初始化 npm init

通过 npm init 创建一个 package.json 文件

D:\robin\lib\weapp-utils>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>` 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: (weapp-utils)
version: (1.0.0)
description: some foundmental utils for weapp
entry point: (lib/index.js)
test command:
git repository:
keywords: weapp,utils
author: tusi666
license: (ISC) MIT
About to write to D:\robin\lib\weapp-utils\package.json:

{
  "name": "weapp-utils",
  "version": "1.0.0",
  "description": "some foundmental utils for weapp",
  "main": "lib/index.js",
  "scripts": {"test": "echo \"Error: no test specified\"&& exit 1"},
  "keywords": [
    "weapp",
    "utils"
  ],
  "author": "tusi666",
  "license": "MIT"
}

其中 main 字段是入口文件

写好 README

一个完备的 README 文件是必要的，以便别人了解你的包是做什么用途。

确认 registry

一般我们开发时会修改 npm registry 为https://registry.npm.taobao.org。

但是发布 npm 包时，我们需要将其改回来，不然是会报错的。

npm config set registry http://registry.npmjs.org/

npm 注册账号

打开 npm 官网，开始注册账号。

ps：记得要验证邮箱哦！

添加 npm 账户

使用 npm adduser 添加账户，别名npm login

D:\robin\lib\weapp-utils>npm adduser
Username: tusi666
Password:
Email: (this IS public) cumtrobin@163.com
Logged in as tusi666 on https://registry.npm.taobao.org/.

添加 github 仓库

在 package.json 添加配置项，不加也没事，看自己需求。

"repository": {
  "type": "git",
  "url": "https://github.com/xxx/zqh_test2.git"
}

发布

npm publish

如果发布时报这样的错，

The operation was rejected by your operating system.
npm ERR! It's possible that the file was already in use (by a text editor or antivirus),
npm ERR! or that you lack permissions to access it.

建议还是检查下 registry，或者npm adduser 是不是成功了。

发布成功，会有这样的提示，

npm notice

npm notice

上 npm 搜索weapp-utils，发现有了！

调用

发布成功了，也要验证下，是否可正常使用。

import {merge} from "weapp-utils"

let mergedOptions = merge(DEFAULT_OPTIONS, options)
