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. 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. The encodeURI() function encodes a URI by replacing each instance of certain characters by one, two, three, or four escape sequences representing the UTF-8 encoding of the character (will only be four escape sequences for characters composed of two 'surrogate' characters). This method is suitable for encoding URL components such as query string parameters and not the complete URL. 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. To get URL parameters with Node.js and Express, we can use the req.params property. 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. When a user submits a login form, they send a request back to the server. The server will respond with the appropriate web page data. A request is sent to the server when a user enters a specific URL (say ). How to read and write Excel file in Node.URL encoding is commonly used to avoid cross-site scripting (XSS) attacks by encoding special characters in a URL. The get method fetches data stored on the web server.
