If you want to learn more about Base64 conversions in JavaScript, read this guide.This syntax imports the encoding/base64 package with You can even use it to perform ASCII, HEX, UTF-16, and UCS2 encodings and decodings. The Buffer object is not just limited to Base64 conversions. We looked at how to use the native Buffer module to perform the Base64 encoding and decoding in a Node.js application. That's all for Base64 encoding and decoding in Node.js. log (str ) // Base64 Encoding in Node.js Conclusion toString ( 'utf-8' ) // print normal stringĬonsole. from (base64, 'base64' ) // decode buffer as UTF-8 const str = buff. Here is what it looks like: // Base64 encoded string const base64 = 'QmFzZTY0IEVuY29kaW5nIGluIE5vZGUuanM=' // create a buffer const buff = Buffer. All you need to do is create a buffer from the Base64 encoding string by using base64 as the second parameter to om() and then decode it to the UTF-8 string by using the toString() method. The Base64 decoding process is very much similar to the encoding process. The second parameter in om() is optional when dealing with plain-text (UTF-8) strings. In the above example, we created a buffer from the string and used the toString() method to decode the buffer as a Base64 string. log (base64 ) // QmFzZTY0IEVuY29kaW5nIGluIE5vZGUuanM= toString ( 'base64' ) // print Base64 stringĬonsole. from (str, 'utf-8' ) // decode buffer as Base64 const base64 = buff. Here is an example: // plain-text string const str = 'Base64 Encoding in Node.js' // create a buffer const buff = Buffer. If no character encoding is specified, UTF-8 will be used as the default. ![]() This method takes two parameters, a plain-text string, and the character encoding, and creates a buffer or binary data array for the given encoding. To convert a string into a Base64 encoded string, we first create a buffer from the given string using the om() method. Let us look at the below examples that explain how to use the Buffer object to perform Base64 encoding and decoding in a Node.js application. This includes to and from UTF-8, UCS2, Base64, ASCII, UTF-16, and even the HEX encoding scheme. The Buffer object provides several methods to perform different encoding and decoding conversions. Internally, Buffer represents binary data in the form of a sequence of bytes. Buffer is available as a global object, and you don't need to explicitly require this module in your application. Luckily, Node.js provides a native Buffer module that can be used to perform Base64 encoding and decoding. These methods are part of the window object and are only available in the browser. Unfortunately, Node.js doesn't support standard JavaScript functions like atob() and btoa() for Base64 encoding. ![]() Today, you'll learn how to do the Base64 encoding and decoding in a Node.js application. ![]() In an earlier article, we looked at how to Base64 encode and decode a string in Java and JavaScript. ![]()
