Pass array of objects in query string node.js

Question

If I want the Node.js query parser to parse an array, I can send this:

'?or=foo&or=bar' // gets me { or: ['foo', 'bar'] }

If I want an object I can do this:

'?or[foo]=bar' // gets me { or: {foo: 'bar'}}

But how do I get an array of objects? I'd like this output:

{ or: [{foo: 'bar'}, {bar: 'baz'}]}

doesn't work. I just get this mess: { '{"or":': { '{"foo":"bar"},{"bar":"baz"}]': '' } } — Rob Allsopp

With the qs module, you can get the object you're looking for if you use this format:

or[0][foo]=bar&or[1][bar]=baz

Wow that worked without the module actually. Thanks!

You can use options allowDots.

const stringParams = qs.stringify(params, {allowDots:true});
// myArray[0].name=MeWhit
qs.parse(stringParams , {allowDots: true});
// [{ name: MeWhit}]
