This module provides utility methods for parsing and formatting URL query strings: const querystring = require ( 'querystring' ) const baseUrl = '' const query = 'SELECT * from users WHERE id = 1' // Encode query string const encodedQuery = querystring. You could also use the Node.js built-in querystring module to encode a URL. log (url ) // *%20from%20users%20WHERE%20id%20%3D%201 querystring Module How to URl encode strings in Node.js To URl encode strings in Node.js, we can call encodeURIComponent.
Here is an example: const baseUrl = '' const query = 'SELECT * from users WHERE id = 1' // Encode query string const encodedQuery = encodeURIComponent (query ) // Build full URL const url = baseUrl + encodedQuery // Print full URLĬonsole. This method is suitable for encoding URL components such as query string parameters and not the complete URL. Javascript queries related to express url encoded express.urlencoded urlencoded express express body parser express.urlencoded() express body-parser. To encode special characters in URI components, you should use the encodeURIComponent() method. log (encodedUrl ) // !Learn%20Node$/%20Example encodeURIComponent() Method This method encodes special characters except characters: const url = '!Learn Node$/ Example' // Encode complete URL const encodedUrl = encodeURI (url ) // Print encoded URLĬonsole. The encodeURI() method is used to encode a complete URL. Since Node.js is a JavaScript runtime built on Chrome's V8 JavaScript engine, you can use JavaScript methods such as encodeURI() and encodeURIComponent() to encode a URL. In this article, you'll learn how to encode or decode a URL string and query string parameters in a Node.js application. It converts a string into a valid URL format that makes the transmitted data more reliable and secure.
