Question

In the nodejs documentation:

query: Either the ‘params’ portion of the query string, or a querystring-parsed object.
Example: 'query=string' or {'query':'string'}

Link: NodeJS URL

This part is confusing.

1. When will 'query=string' happens?
2. When will this
   {'query':'string'} also happens?

I have seen that when I do url.parse() it automatically converts the parameters into an object. My code will be buggy if I only support one format.

How will I know if url.parse() converts the parameters in this format: 'query=string'?

Answer 1

url.parse(urlStr, [parseQueryString], [slashesDenoteHost])

If you pass true as the second argument it will also parse the query string using the querystring module and you will get an object {'query':'string'}, otherwise the query string will not be parsed (default behavior) and you will get query=string.
