Querystring is an important module in the node.js as it offers the main utilities for formatting and parsing the URL query strings. This module can be accessed in different ways like;
Querystring.parse
This is one the ways of assessing querystring. It has thee different options like that includes str,sep, options, and eq. The sep is a substring used in delimiting value pairs and key the query string. On the other hand the eq is also used for the values and key delimitation. This, gtherefore, implies that the querytring .parse is recommended for parsin the URL query string into value pairs and key collections. The URL query to parse is the str.
Querystring.escape(str)
The querystring.escape option allows you to carry out the URL percent-encoding. This occurs on specific str in a way that it can optimize all the requirements of query string. This method is mainly used by the querystring.stringify; hence not suitable for direct use. This application offers replacement percent encoding where necessary. This is because it is primarily exported to perform the code application.
Querystring.stringify
The querystring.stringify is a method of producing the query string URL from a specific object. This is by the use of iterating via the own properties of the object. It has four options that include; the sep, obj,options, and eq. just like Querystring.parse, this application contains the sep that is employed in delimiting the key and values pairs. The eq only delimit the values and keys
Querystring.unescape
This is a method of carrying out the URL percent-encoded character decoding on specific str. It is not suitable for direct use, but recommended for the querystring.parse. This method may use the JavaScript in decoding by default. It is also primarily exported to offer replacement for decoding whenever required.
These are some the simple ways of accessing the querystring on the node.js. They are simple and effective ways that will enable you to create the URL.
