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 + encodedQueryĬonsole. This method is suitable for encoding URL components such as query string parameters and not the complete URL. You should use the encodeURIComponent() method to encode special characters in URI components. log (encodedUrl ) // !Learn%20Node$/%20Example encodeURIComponent() Method The encodeURI() method encodes a complete URL, including encodes special characters except characters: const url = '!Learn Node$/ Example' // Encode complete URL const encodedUrl = encodeURI (url ) // Print encoded URLĬonsole. 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 making the transmitted data more reliable and secure. URL encoding is commonly used to avoid cross-site scripting (XSS) attacks by encoding special characters in a URL.
