Query string#
Source Code: lib/querystring.js
The node:querystring module provides utilities for parsing and formatting URL
query strings. It can be accessed using:
const querystring = require('node:querystring'); querystring is more performant than <URLSearchParams> but is not a
standardized API. Use <URLSearchParams> when performance is not critical or
when compatibility with browser code is desirable.
querystring.decode()#
The querystring.decode() function is an alias for querystring.parse().
querystring.encode()#
The querystring.encode() function is an alias for querystring.stringify().
querystring.escape(str)#
str<string>
The querystring.escape() method performs URL percent-encoding on the given
str in a manner that is optimized for the specific requirements of URL
query strings.
The querystring.escape() method is used by querystring.stringify() and is
generally not expected to be used directly. It is exported primarily to allow
application code to provide a replacement percent-encoding implementation if
necessary by assigning querystring.escape to an alternative function.
