I need to pass multiple values i.e a collection for a particular query key in express.

My memory might be tricking me, but I am inclined to believe that I have seen something like this somewhere on the web:

http://<somehost>/<somepath>?id[]=10&id[]=11&id[]=12

I know that Ruby on Rails returns these querystring values as an array but I thought express had some similar querystring behaviour but I can't find it in their documentation.

Have I missed something?

node.js express

Meanwhile I've found out that it actually works with express.

This querystring

http://<somehost>/<somepath>?id[]=10&id[]=11&id[]=12

is being parsed into an array by express js. Thus

req.query.id => ["10","11","12"]

This should be mentioned in the express documentation.

In fact express makes use of a package named 'qs', which is worth taking a closer look at:

https://github.com/ljharb/qs

It even does deep nesting like

http://<somehost>/<somepath>?persona[country][birth]=us&person[country][resident]=de

which is being parsed into

 person: country: birth: 'us', resident: 'de'
