Therefore, to properly decode strings that are encoded with multibyte binary data, you should use the " utf8" encoding method with the Buffer.toString() method, for example, like so:Ĭonst fromBase64 = (str) => om(str, 'base64').toString('utf8') Ĭonsole.log(fromBase64('8J+mig=')) // '□'Ĭonsole.log(fromBase64('44GT44KT44Gr44Gh44Gv')) // 'こんにちは'Ĭonsole.log(fromBase64('Zm9vYmFy')) // 'foobar' so first of all you have used new Buffer which is already deprecated, so i suggest you to use this. Take a look at this Stackoverflow question. For example, you can achieve this in the following way:Ĭonst binaryStrBuffer = om(encodedStr, 'base64') Ĭonst decoded = binaryStrBuffer.toString('ascii') Īlthough encoding to an " ascii" string is fast, it is limited to working only with strings that are encoded with single-byte binary data, which means that it may not be suitable for decoding multibyte base64-encoded strings.įor example, consider the following multibyte base64-encoded string that represents a fox emoji ( □), but incorrectly outputs " p&" with " ascii" string encoding:Ĭonst binaryStrBuffer = om('8J+mig=', 'base64') Ĭonst decoded = binaryStrBuffer.toString('ascii')) Some browsers such as Firefox, Chrome, Safari, Opera and IE10+ can handle Base64 natively. The regex replacement is optional and is just there to deal with prefix as in the case of dataurl string. const byteArray new Buffer (base64String.replace (/ \w\d :\/+base64\,/g, ''), 'base64') base64String is the string containing the base 64 string. var base64 'SGVsbG8gd29ybGQ' var words (base64) var textString (words) // 'Hello world' Some explanation As you can see from the examples given in the CryptoJS documentation, parse is meant to parse a string in the format that the encoder is expecting (into a WordArray), and. ![]() ![]() Similar to encoding a base64 string, the easiest way to decode a base64-encoded string in Node.js is to use the built-in Buffer object. This would prove to be much short solution. ![]()
