+# h-mysql
+
+* **作者**：浪子神剑
+* **邮箱**：<[email protected]> 
+* **网站**：[http://www.haizlin.com](http://www.haizlin.com)
+* **介绍**：一直以来很喜欢Thinkphp的数据操作风格，所以在nodejs上也封装了一个MYSQL数据库的常用操作，支持链式调用，实现语义化的数据库操作。
+
+## 安装及引用
+
+```javascript
+
+// npm安装
+npm i h-mysql --save
+
+// yarn安装
+yarn add h-mysql
+
+const hMysql = require('h-mysql');
+```
+
+## 初始化配置
+```javascriipt
+const hMysql = new mysql({
+  host: '127.0.0.1',
+  user: 'root',
+  password: '',
+  database: 'test-db',
+  port: 3306,
+
+  acquireTimeout: 1000,
+  waitForConnections: true,    //是否等待链接  
+  connectionLimit: 10,  // 连接池数
+  queueLimit: 0, // 排队限制 
+
+  defaultSqlPre: '',
+  isPool: true,
+  isDebug: true
+});
+
+const {error, result} = await hMysql.table('user')
+  .where({ id: 100 })
+  .select()
+  .execSql();
+
+console.log(result);
+```
+
+## 调用方式
+> 规则：调用方法跟顺序无关
+```javascript
+let hMysql = new hMysql(config)
+
+hMysql.table()
+      .where()
+      .limit()
+      .select()
+      .execSql()
+```
+
+## [CURD操作](./docs/api.md)
+* 添加：[insert] [table] [data]
+* 查询：[select] [field] from [table] [alias] [where] [join]
+* 更新：[update] [table] set [data] [where]
+* 删除：[delete] from [table] [where]
+
+## [API 文档](./docs/api.md)
+* CURD操作
+  * [.select()]() ⇒ Promise
+  * [.find()]() ⇒ Promise
+  * [.update()]() ⇒ Promise
+  * [.updateMany()]() ⇒ Promise
+  * [.insert()]() ⇒ Promise
+  * [.delete()]() ⇒ Promise
+  * [.query(sql: string)]() ⇒ Promise
+
+* 链式方法
+  * [.table(tableName: string)]() ⇒ Mysql
+  * [.alias(tableAlias: string)]()⇒ Mysql
+  * [.field(opt: string | any[])]() ⇒ Mysql
+  * [.where(opt: string | any[])]() ⇒ Mysql
+  * [.limit(limit)]() ⇒ Mysql
+  * [.page(pageSize, pageNum)]() ⇒ Mysql
+  * [.data(data:object)]() ⇒ Mysql
+  * [.order(order)]() ⇒ Mysql
+  * [.join()]() ⇒ Mysql
+  * [.union()]() ⇒ Mysql
+  * [.count()]() ⇒ Promise
+  * [.group(field)]() ⇒ Mysql
+  * [.having(field)]() ⇒ Mysql
+  * [.count(field)]() ⇒ Mysql
+  * [.max(field)]() ⇒ Mysql
+  * [.min(field)]() ⇒ Mysql
+  * [.avg(field)]() ⇒ Mysql
+  * [.sum(field)]() ⇒ Mysql
+  * [.lock(field, step)]() ⇒ Promise
+  * [.distinct(field, step)]() ⇒ Promise
+  * [.comment(str:string)]() ⇒ Promise
+  * [.execSql()]() ⇒ string
+
+## 迭代计划
+- [ ] 完善API文档、架构文档
+- [ ] 完善案例
+- [ ] 批量插入、批量更新、批量删除
+- [ ] 支持更复杂的链式操作
+- [ ] 添加测试用例
+- [ ] 重写异常处理方式
+- [ ] 添加性能测试并添加每条语句执行的时间
+- [ ] 添加安全测试，防注入
+- [ ] 增加对数据库的操作（现在的功能都是针对表）
+- [ ] 考虑是不是要支持ORM
+
+
+## 版本更新
+* v0.0.1
+  * 实现常用方法的链式调用，未经过测试，慎用到生产环境，待更新到1.0版本吧
