nodejieba-for-alicloudspace-uniapp

uni-app 云函数云对象 存储中文数据,中文分词,实现中文全文检索,node结巴分词

专用于阿里云空间,云空间不支持自带文件,只能上传到npm,让阿里云执行npm install来安装这个插件

如果是其他系统,用不了这个插件的,只能用于Linux x64 gnu

如果是其他系统,可以到@node-rs/jieba下载文件,自己打包到npm

把JS打包到npm教程

1. 到npm官网注册一个账号(账号名,>8位密码,邮箱一个)
2. 回到自己的包文件夹,新建一个package.json文件

	文件名: package.json
	内容如下:
	
	{
      "name": "nodejieba-for-alicloudspace-uniapp",
      "version": "1.0.0",
      "description": "Fastest Chinese word segmentation in Node.js",
      "keywords": [
        "Jieba",
    	"uniapp",
    	"nodejieba"
      ],
      "author": "作者 <作者邮箱>",
      "homepage": "",
      "license": "MIT",
      "main": "index.js",
      "files": [
        "index.js",
        "jieba.linux-x64-gnu.node",
        "LICENSE"
      ],
      "engines": {
        "node": ">= 10"
      },
      "publishConfig": {
        "registry": "https://registry.npmjs.org/",
        "access": "public"
      },
      "repository": {
        "type": "git",
        "url": "git+"
      },
      "bugs": {
        "url": ""
      },
      "devDependencies": {
        "nodejieba": "^2.6.0"
      },
      "funding": {
        "type": "",
        "url": ""
      }
    }  

	除了`name` `main` `version`字段,其余都不重要,  
	其中`name`是包名,不能有大写,不能是在`npm`能搜索到的包名,  
	`main`为这个包的入口文件,文件名随意

3. 包里面js文件写好
4. 在当下文件夹地址栏键入 cmd 进入命令行模式
5. 然后输入命令: npm login
6. 按提示一次输入: 用户名 密码 邮箱
7. 去 邮箱 接收一个8位数密码
8. Enter one-time password: 输入邮箱收到的8位数密码
9. 登录成功,输入命令: npm publish
10. 发布成功,在需要你这个包的文件夹地址栏键入cmd,进入命令行,[npm install 包名] 安装对应的包
11. 如果想只用一个npm install 自动为你的文件夹[专业术语叫:包]安装所需要的插件[专业术语叫:依赖]
    阿里云就是自动执行的这一句,不允许自带文件包
12. 可以在package.json文件中添加根字段

"dependencies": {
		"依赖需要的包名1":"发布时写的version版本号 1.0.0",
		"依赖需要的包名2":"发布时写的version版本号 1.6.5",
		...
}

13. 更新包:npm version patch + npm publish 两步命令

copy from @node-rs/jieba

jieba-rs binding to Node.js

Without node-gyp

node-rs/jieba was prebuilt into binary already, so you don't need fighting with node-gyp and c++ toolchain.

Performance

Due to jieba-rs is 33% faster than cppjieba, and N-API is faster than v8 C++ API, @node-rs/jieba is faster than nodejieba.

@node-rs/jieba x 3,763 ops/sec ±1.18% (92 runs sampled)
nodejieba x 2,783 ops/sec ±0.67% (91 runs sampled)

Usage

const { load, cut } = require('@node-rs/jieba')

load()
// loadDict(fs.readFileSync(...))
// loadTFIDFDict(fs.readFileSync(...))

cut('我们中出了一个叛徒', false)

// ["我们", "中", "出", "了", "一个", "叛徒"]

const { load, cut } = require('@node-rs/jieba')

load()
