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' Encoding the original string to base64: The Buffer class in Node. 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')) Base64 encoding and decoding can be done in Node.js using the Buffer object. Buffer const path = require ( 'path' ) const fs = require ( 'fs' ) /** * encode_base64 ( 'ddr.jpg' ) decode_base64 ( 'any_base64_string_goes_here', 'rane.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. There are 40 other projects in the npm registry using node-base64-image.

To encode data, specify it in the Buffer instance and string base64 encoding format, as follows. The Buffer class plays a significant role in Nodejs base64 encode. base64 encoding & decoding in node.js Written by Mudaser Ali More from Mudaser Ali React Native Sticky Date like whatsapp using Inverted SectionList Setup. I post the src of an img to my node/express. Heres how to do Base64 encoding and decoding using Buffer in Node. It walks you from manual to the terminal to (simple and complex) Nodejs file encoding. I know this question is asked several times, but unfortunately nothing seems to work for me. In Node. This tutorial explains Nodejs' significance in data encoding. Start using node-base64-image in your project by running npm i node-base64-image. In this tutorial, we are going to learn about encoding and decoding strings with base64 format in Node.js. High performance Base64 encoding and decoding for Node.js using SIMD (AVX2, AVX, SSE4.2, SSE4.1, SSSE3) acceleration. Latest version: 2.0.5, last published: 5 months ago. This can be done using the om() method that accepts the string to be converted and the current encoding of the string. Encoding the original string to base64: The Buffer class in Node.js can be used to convert a string to a series of bytes. 'use strict' // node v8.11.3 const Buffer = require ( 'buffer' ). Download images from remote URLs and encode/decode them to base64. Base64 encoding and decoding can be done in Node.js using the Buffer object.
