If you would like to learn more about how base64 is encoded in general, and in JavaScript in-particular, I would recommend this article: Computer science in JavaScript: Base64 encoding $scope.encoded = $base64.encode('a string') To decode a base64-encoded string: var bytes = (str) To encode an array of bytes using 64: var str = (myByteArray) We can make it convert to other formats by passing the encoding type to toString().Īnd here is how you decode base64 encoded strings: var b = om('SmF2YVNjcmlwdA=', 'base64') If we don't use toString(), JavaScript assumes we want to convert the object to utf8. Base64 encoding and decoding Failed to execute btoa on Window: The string to be encoded contains characters outside of the Latin1 range. The following script provides a text area to. Default is utf8, possible encoding types are ascii, utf8, ucs2, base64, binary, and hex Base64 decoding and encoding in JavaScript is handled through the atob() and btoa() functions respectively.
Here is how you encode normal text to base64 in Node.js: //Buffer() requires a number, array or string as the first parameter, and an optional encoding type as the second parameter. Re-written and modularized UTF-8 and Base64 Javascript Encoding and Decoding Libraries / Modules for AMD, CommonJS, Nodejs and Browsers. Internet Explorer 10+ // Define the stringĬonsole.log(encodedString) // Outputs: "SGVsbG8gV29ybGQh"Ĭonsole.log(decodedString) // Outputs: "Hello World!"
