Introduction mongodb-plus

Introduction mongodb-plus

• This is a plugin that was created to make it easy to operate the mongodb database in nodejs，Maybe everyone has heard of mongoose, indeed mongoose is also very good, but there are model objects in mongoose that limit the input data. I don’t like this limitation very much, so I created this plugin 23333.
• I am encapsulating based on the native method of mongodb，It is highly compatible with the original method, but it is more convenient，The method is named the same as the native method, so that you can get started directly，The method I divided into two types:One is an improved native method (with Sync ending)，The other is based on Promise encapsulation (without Sync)，Can be used in conjunction with async asynchronous function (comfortable with koa)
• This plugin is essentially a syntactic sugar，Is that you can use nodejs to operate the mongodb database more convenient，But essentially the native mongodb method, so there is no change in performance

Use of mongodb-plus

1. installation

npm i mongodb-plus

2. Connect mongodb

//import mongodb-plus
const db = require("mongodb-plus")
//The way to connect to the database is the same as the native,I don't make too many changes here
db.connect("mongodb://localhost:10086/demo1").then(()=>{
    console.log("connected...")
}).catch(err=>{
    console.log(err)
})

3. For the use of the method, see the table below:

method	parameter	way
insert	insert(collection,data)	Based on Promise
insertSync	insertSync(collection,data,callback)	native-based
insertOne	insertOne(collection,data)	Based on Promise
insertOneSync	insertOneSync(collection,data,callback)	native-based
insertMany	insertMany(collection,data)	Based on Promise
insertManySync	insertManySync(collection,data,callback)	native-based
find	find(collection,data[,limitValue,skipValue,sort])	Based on Promise
findSync	findSync(collection,data,callback[,limitValue,skipValue,sort])	native-based
findOne	findOne(collection,data)	Based on Promise
findOneSync	findOneSync(collection,data,callback)	native-based
updateOne	updateOne(collection,data1,data2)	Based on Promise
updateOneSync	updateOneSync(collection,data1,data2,callback)	native-based
updateMany	updateMany(collection,data1,data2)	Based on Promise
updateManySync	updateManySync(collection,data1,data2,callback)	native-based
deleteOne	deleteOne(collection,data)	Based on Promise
deleteOneSync	deleteOneSync(collection,data,callback)	native-based
deleteMany	deleteMany(collection,data)	Based on Promise
deleteManySync	deleteManySync(collection,data,callback)	native-based
deleteCollection	deleteCollection(collection)	native-based

4. for example

const db = require("mongodb-plus")
//db.connect("mongodb://localhost:10086/demo1")
db.connect("mongodb://localhost:10086/demo1").then(()=>{
    console.log("connected...")
}).catch(err=>{
    console.log(err)
})

//Use the native-based method findSync
db.findSync("people",{},data=>{
    console.log(data)
})
//Use the Promise-based method find
db.find("people",{}).then(data=>{
    console.log(data)
}).catch(err=>{
    console.log(err)
})

//You can also use it with async asynchronous functions
async function show(){
    const data = await db.find("people",{})
    console.log(data)
}
show()

//insert
db.insert("people",{ username:"laowang", password:"lw12345" }).then(result=>{
    console.log(result)
}).catch(err=>{
    console.log(err)
})

//Or use insertSync
db.insertSync("people",{ username:"laodi", password:"ld12345" },function(){
    console.log("insert successful...")
})
