You should instead use buffer.toString ('base64') to get base-64 encoded of the buffer content. These methods offer flexibility and convenience depending on your specific requirements. Basically the Buffer class represents byte streams, it's only when you convert it from/to strings that encoding comes into context. In this article, we explored three methods to perform Base64 encoding in Node.js, including using the built-in `Buffer` class, the `btoa()` and `atob()` functions, and the `base64-js` package. The `om(data)` method converts the string `data` into a buffer, which is then passed to `fromByteArray()`.īase64 encoding is a crucial technique for converting binary data into a text representation, especially when working with protocols or systems that require text-based data. In this example, we import the `base64-js` package and use the `fromByteArray()` function to perform Base64 encoding. Once installed, you can use it in your Node.js application as follows:Ĭonst encodedData = omByteArray(om(data)) One such package is `base64-js`, which provides a comprehensive set of Base64 encoding and decoding functions. If you need more control or additional functionalities, you can use third-party packages available on npm. The result is the same as in the previous example. In this code snippet, we create a `Buffer` instance from the string `data` and use the `toString()` method to encode it in Base64 format. There are 51 other projects in the npm registry using nodejs-base64. Start using nodejs-base64 in your project by running npm i nodejs-base64. Latest version: 2.0.0, last published: 3 years ago. To use them, you need to access them through the `Buffer` object. The ultimate shortcut to the base64 encode/decode functions. However, these functions are not available in the global scope by default in Node.js. The `btoa()` function is used for Base64 encoding, while `atob()` is used for Base64 decoding. Node.js also provides the `btoa()` and `atob()` functions, similar to those found in browsers. After cloning this repository, run npm install to install the dependencies needed for development and testing. Here is an example: // plain-text string const str 'Base64 Encoding in Node.js' // create a buffer const buff om( str, 'utf-8') // decode buffer as Base64 const base64 buff.toString('base64') // print Base64 string console.log( base64) // QmFzZTY0IEVuY29kaW5nIGluIE5vZGUuanM. Method 2: Using the built-in `btoa()` and `atob()` functions base64 is designed to work in at least Node.js v0.10.0, Narwhal 0.3.2, RingoJS 0.8-0.9, PhantomJS 1.9.0, Rhino 1.7RC4, as well as old and modern versions of Chrome, Firefox, Safari, Opera, and Internet Explorer. The resulting encoded data is stored in the `encodedData` variable and printed to the console. Then we call the `toString()` method on the buffer, passing `'base64'` as the encoding. In the above code, we first create a `Buffer` instance from the string `data`. Let's look at an example:Ĭonst encodedData = om(data).toString('base64') By passing `'base64'` as the encoding, we can easily perform Base64 encoding. It includes a method called `toString()`, which accepts an optional encoding parameter. Node.js provides the `Buffer` class, which can be used for handling binary data. Method 1: Using the built-in Buffer class
