log( 'Base64 Encoded:', base64Encoded) Ĭonsole. ![]() Decode Base64 to binary data const decodedData = Buffer. Base64-encoded string to be decoded const base64Encoded = 'QjY0RW5jb2RlLmNvbQ=' Import the 'Buffer' class const = require( 'buffer') Finally, we print both the original data and the Base64 encoded result to the console. Using the toString('base64') method, we encode the binary data into a Base64-encoded string. We create a Buffer instance containing the binary data to be encoded (in this case, a UTF-8 encoded string). In this example, we import the Buffer class from the ‘buffer’ module. Example: String to Base64 in Node.js and TypeScript This method accepts a Base64-encoded string as input and returns the binary data. Similarly, the Buffer class provides the from() function with the 'base64' encoding option for Base64 decoding. This method accepts binary data and outputs a Base64-encoded string. The Buffer class provides the toString() method with the 'base64' encoding option for Base64 encoding. The Buffer class is a crucial component of the Node.js standard library, allowing developers to effectively perform a variety of operations on binary data. It supports both Base64 encoding and decoding, making the procedure as simple as possible. The Buffer class in Node.js is essential for working with binary data. Node.js, a runtime environment based on Chrome’s V8 JavaScript engine, does, in fact, natively handle Base64 encoding and decoding. Base64 Encoding and Decoding in Node.js with Buffer class TypeScript code can be run on any browser or JavaScript engine that supports ECMAScript 3 or later. This makes it possible to write future-proof code. TypeScript also includes features from the upcoming ECMAScript versions like classes, modules, and interfaces. These types make it easier to refactor code, navigate through your projects, and catch common bugs, thus making the development process more efficient. The main goal of TypeScript is to enhance the productivity of developers when working on large JavaScript applications by adding static types. It was developed and is maintained by Microsoft. TypeScript is a statically typed superset of JavaScript that compiles to plain JavaScript. However, Node.js allows developers to use V8 outside of the browser context, allowing JavaScript code to be executed on the server side. Node.js makes use of Google’s V8 JavaScript engine, which is best known for its use in the Chrome browser. It is intended to be efficient and scalable, making it ideal for developing real-time web applications and APIs. Node.js is an open-source, cross-platform runtime environment that allows developers to create and run server-side JavaScript applications. Online Base64 Translator What is Node.js? It is a useful method in a wide range of computer applications due to its widespread support across programming languages and ease of use. While Base64 encoding does not provide encryption or security in and of itself, it is a required tool for tasks like sending binary data over URLs, embedding graphics within web pages, and attaching files to emails. ![]() ![]() The padding character ‘=’ ensures that the encoded text’s length is a multiple of four, resulting in a consistent format. While Base64 encoding increases data size by around one-third when compared to its original binary form, its dependability and suitability for text-based settings make it a popular technique in a wide range of applications, particularly web development.Įncoding is the process of dividing binary data into little bits and mapping them to letters such as ‘A’ to ‘Z’, ‘0’ to ‘9’, and ‘+’ and ‘/’. These characters were chosen with great care to ensure compatibility and secure transmission. When binary data, such as images or files, must be represented using just readable characters, this encoding approach is extensively utilized.īase64 separates binary data into six-bit groups that are then mapped to specific ASCII letters. This is accomplished by converting binary data into a series of printable ASCII characters, enabling for secure transmission over a number of text-oriented protocols. What is Base64?īase64 is a binary-to-text encoding technique used to convert digital data into a text-based communication format. Learn how to convert binary data to a text-based format for secure transmission and storage, and reverse the process to retrieve the original data. ![]() Explore the fundamentals of Base64 encoding and decoding in Node.js and TypeScript using the built-in Buffer class.
