koa-mongoose-short

最近想重构博客(原express, 改koa),发现又得折腾下百度云的mongodb短连接,于是做个简易点的mongodb短连接,且支持mongoose

dependencies

  • koa@1.x
  • mongoose@4.x

属性

  • mongoose {object} 即mongoose
  • db {object} 存放mongoose.createConnection
  • connect {function} 创建koa中间件,参数是一个对象{object}
    • url mongodb数据库连接地址 (mongo://user:pass@host:port/dbname)
    • idleTimeoutMillis 超时时间,默认30000
    • max 最大连接数,默认10
    • min 最小连接数,默认0
    • log pool日志,默认false

使用方法

目前暂定只支持数据库连接参数来链接

var koa      = require('koa');
var app      = koa();
var koashort = require('koa-mongoose-short')
app.use(koashort.connect({
	url: 'mongodb://127.0.0.1:27017/koatest'
}));
app.use(function* (){
	this.body = 'hello world'
});
app.listen(11234);

mongoose文档对象开发姿势

详细可见/example/connect.js, 个人喜欢把schema挂载到this上面

// db.js
var koashort = require('koa-mongoose');
var Schema   = koashort.mongoose.Schema;
var UserSchema = new Schema({
	name:  String,
	pass:  String,
	email: String
});
// schema生成model的过程只允许发生一次,所以放在外部
var User = koashort.db.model('User', UserSchema);
module.exports = function(){
	return function* (next){
		this.model = this.model || {};
		if( !this.model.user ) this.model.user = User;
		yield next;
	}
}

// main.js
// ...
app.use(koashort.connect({
	url: 'mongodb://192.168.80.40:27017/koatest'
}));
app.use( require('./db.js')() );
app.use(function* (){
	// 请确保user表存在数据
	this.body = yield this.model.user.findOne();
});
// ...

example

// listen to 11234, 默认数据库连接地址:mongodb://127.0.0.1:27017/koatest
node ./example/connect.js
