Let base64String = bufferObj.toString("base64") Ĭonsole.log("The encoded base64 string is:", base64String) Output C:\home\node> node base64.js 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). 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. Creating the buffer object with utf8 encoding URL encoding is commonly used to avoid cross-site scripting (XSS) attacks by encoding special characters in a URL. Live Demo // Base64 Encoding Demo Example After creating the file, use the command " node base64.js" to run this code.

The buffer class can be used to encode a string into a series of bytes. Base64 is used to represent binary data in an ASCII string format by translating it into a radix-64 representation.
The buffer class can be used to encode a string into a series of bytes. The buffer object can be encoded and decoded into Base64 string. Base64Encode.io A simple web tool to help you in encoding your string data into base64 format and decode base64 data into plain text. TLDR they add a handy req.The buffer object can be encoded and decoded into Base64 string. Passing the extended: true option to urlencoded will further parse nested structures sent in the urlencoded payload. This is most commonly found when posting with an HTML form to your server, since urlencoding is the default. This breaks down badly on binary data like a PDF, corrupting the data and making it unusable.
Urlencoded does a similar thing, it parses the fields included in a urlencoded payload sent with a request to your server, and adds their values into a body object on the request. The problem here is that we use strings to represent the response data, and Node assumes those strings are UTF-8 encoded. req.body), or an empty object () if there was no body to parse, the Content-Type was not matched, or an error occurred. From the express docs :Ī new body object containing the parsed data is populated on the request object after the middleware (i.e. The json middleware will parse incoming request bodies that have content type json headers. These both parse incoming requests, not outgoing responses. You need a library like URI.js to convert between a URI and IRI (Internationalized Resource Identifier). The comments talking about what is sent back from your server are irrelevant to why we use these middlewares, and in fact the middlewares do not affect our response at all. Note that URI encoding is good for the query part, it's not good for the domain.
