Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

更新日志

目前支持的数据库有:

| 数据库 | 说明 | 支持版本 | | ------- | --------------------------------------------- | :------- | | FastDB | 本地json文件数据库[由access_db团队开发] | 0.5.0 | | MongoDB | 分布式文件存储数据库 | 4.x | | Mysql | 关系型数据库 | 8.x, 5.x | | Redis | 高性能的 key-value 数据库 | 6.x, 5.x | | Elaticsearch | 搜索引擎 | 8.x | | Mssql | microsoft sql server | 2017+ |

使用示例:

import {
  mysql, mongodb, redis, fastdb, 
  elasticsearch, mssql
} from 'access-db'

async function exp() {
  fastdb.set('city', {id: 1, name: 'one'})

  await mongodb.get('tableName1', id)

  await mysql.find('tableName2', {
    p0: ['num', '=', 32],
    r: 'p0'
  })

  await redis.set('tableName2', {
    id: 2,
    num: 12
  }, 3000)
}

安装

npm install access-db

在项目根目录新建.env文件,然后填写配置信息

MYSQL_HOST=localhost   // 非必填,不填则表示不使用该数据库
MYSQL_USER=root
MYSQL_PASSWORD=123456
MYSQL_PORT=3306
MYSQL_DATABASE=
# 默认UTF8_GENERAL_CI
# MYSQL_CHARSET=
# 最大连接数,默认10
# MYSQL_CONNECTION_LIMIT=


MSSQL_HOST=localhost
MSSQL_PORT=1433
MSSQL_USER=SA
MSSQL_PASSWORD=83jaidfka3jladjf
MSSQL_DATABASE=access_db
MSSQL_AZURE=1  # 是否是用的 microsoft azure
MSSQL_DEV=1   # 是否是 本地开发 


MONGODB_HOST=localhost    # 非必填,不填则表示不使用该数据库
MONGODB_USER=
MONGODB_PASSWORD=
MONGODB_DATABASE=
MONGODB_PORT=27017

REDIS_HOST=localhost   # 非必填,不填则表示不使用该数据库
REDIS_USER=
REDIS_PASSWORD=
REDIS_DATABASE=
REDIS_PORT=6379


FASTDB_DIR=fastdb   # fastdb的数据存储目录,默认项目根目录下的fastdb目录
FASTDB_PATH=../../../../   #存储位置,默认不填。。如果你要将fastdb方法打包出来,就要配置


ELASTICSEARCH_HOST=localhost
ELASTICSEARCH_PORT=9200
ELASTICSEARCH_USER=elastic
ELASTICSEARCH_PASSWORD=F1V8YE3QyOKUHcQswsbc
ELASTICSEARCH_CA_PATH=/Users/zj/elasticsearch-8.0.1/config/certs/http_ca.crt
ELASTICSEARCH_DATABASE=access_db

node ./server.js # 一定要在项目根目录启动,不然 .env 文件不生效

关于fastdb说明

  1. 数据库为json文件
  2. 每条数据以对象的形式保存,然后一起组成数组
  3. json里没有换行空格符号,当前字段的值是可以包含这些的。
  4. 每条数据最前面都有唯一标识"id":"xxx"(新增(fastdb.set)数据时,会自动生成或调整)
