get method with query params in node js | node js tutorials

 in requesting url if we have query params 

how to deal with that

query takes req,query

if we have matched that with two ids, it wil print two id jsons

app.get("/person_with_query",(req,res,next) =>

{

let idd=req.query.id;

let person=[

{name:"hudere",addr:"vamsi1",id:1},

{name:"hudere",addr:"vamsi2",id:2},

{name:"hudere",addr:"vamsi3",id:3}

];

person=person.filter(x=>x.id==idd);

res.send(person);

})

whole code

const express= require('express');

const app = express();

const PORT=3000;

app.get("/person",(req,res,next) =>

{

let person={name:"hudere",addr:"vamsi"}

res.send(person);

}

);

app.get("/persons/:id",(req,res,next) =>

{

let idd=req.params.id;

let person=[

{name:"hudere",addr:"vamsi1",id:1},

{name:"hudere",addr:"vamsi2",id:2},

{name:"hudere",addr:"vamsi3",id:3}

];

person=person.filter(x=>x.id==idd);

res.send(person);

}

)

app.get("/person_with_query",(req,res,next) =>

{

let idd=req.query.id;

let person=[

{name:"hudere",addr:"vamsi1",id:1},

{name:"hudere",addr:"vamsi2",id:2},

{name:"hudere",addr:"vamsi3",id:3}

];

person=person.filter(x=>x.id==idd);

res.send(person);

})

app.listen(PORT,() =>

{

console.log("server on::"+PORT)

}

)

what it will print

how to write two conditions based on query

we wil take query params as query and 

in filter write with two conditiions

http://localhost:3000/person_with_query?id=1&name=hudere

app.get("/person_with_query",(req,res,next) =>

{

let query=req.query;

let person=[

{name:"huderee",addr:"vamsi1",id:1},

{name:"hudere",addr:"vamsi2",id:2},

{name:"hudere",addr:"vamsi3",id:3},

{name:"hudere",addr:"vamsi3",id:1}

];

person=person.filter(x=>x.id==query.id & x.name ==query.name);

res.send(person);

})

req.query= from request it taks all the query params

then filter based on thta
