I need to create url for get which is going to accept array, how in node.js/express extract array from request ? I need to pass array with names which parametes I need to ba

Answer 1

If you want to pass an array from url parameters, you need to follow the bellow example:

Url example:

https://website.com/example?myarray[]=136129&myarray[]=137794&myarray[]=137792

To retrieve it from express:

console.log(req.query.myarray)
[ '136129', '137794', '137792' ]

Answer 2

Express exposes the query parameter as an array when it is repeated more than once in the request URL:

app.get('/', function(req, res, next) {
   console.log(req.query.a)
   res.send(200)
}

GET /?a=x&a=y&a=z:
// query.a is ['x', 'y', 'z']

Same applies for req.body in other methods.
