Deserialize query string to JSON object

Question

Tried to find how to make {foo:\"bar\"} from ?...&foo=bar&... but googled and got only to jQuery.params which does the opposit

Answer 1

for simple and flat query strings, something like this will do the trick

const queryStringToObject = (queryString) => {
  let obj = {}
  if(queryString) {
    queryString.slice(1).split('&').map((item) => {
      const [ k, v ] = item.split('=')
      v ? obj[k] = v : null
    })
  }
  return obj
}

> queryStringToObject('?foo=bar&baz=buzz')
{ foo: 'bar', baz: 'buzz' }
