Node | URL.format API
  • Last Updated : 20 May, 2019

With the help of url.format()method, we are able to format the hostname according to our need. We have different types of other parameters which we can use to generate the hostname or to change the hostname as required.

Syntax : url.format(URL[, options])
Parameter :

  • auth is a boolean value if true then username and password have to be provided.
  • fragment if true then fragment should be included otherwise not.
  • search if true then provide the search query otherwise not.
  • unicode if true then unicode character appearing in the hostname should be encoded directly otherwise not.

Return : return a newly generate URL or hostname

Example 1 : In this example we first import the url module in node. Then to generate or format the random url we use the url.format() method.
