jape

Jape is a simple way to convert a JSON object to a single URI Encoded string. Such strings can be used in API requests when one wants to use a comfortable JSON object and get it converted to a URL friendly string. It changes ' ' (a space) to %20 and similar, and also supports multi-property objects by concatenating with &.

var jape = require('jape');
var jsonObject = {
    text: 'hello, tworld. welcome to 1.1.',
    screen_name: 'theseancook'
}
jape(jsonObject); //returns 'text=hello%2C%20tworld.%20welcome%20to%201.1.&screen_name=theseancook'
