Yet another Base64 transcoder
$ npm install --save js-base64If you are using it on ES6 transpilers, you may also need:
$ npm install --save babel-preset-envNote js-base64 itself is stand-alone so its package.json has no dependencies. However, it is also tested on ES6 environment so "babel-preset-env": "^1.7.0" is on devDependencies.
<script src="base64.js"></script>var Base64 = require('js-base64').Base64;import { Base64 } from 'js-base64';Base64.encode('dankogai'); // ZGFua29nYWk= Base64.encode('小飼弾'); // 5bCP6aO85by+ Base64.encodeURI('小飼弾'); // 5bCP6aO85by- Base64.decode('ZGFua29nYWk='); // dankogai Base64.decode('5bCP6aO85by+'); // 小飼弾 // note .decodeURI() is unnecessary since it accepts both flavors Base64.decode('5bCP6aO85by-'); // 小飼弾if (Base64.extendString) { // you have to explicitly extend String.prototype Base64.extendString(); // once extended, you can do the following 'dankogai'.toBase64(); // ZGFua29nYWk= '小飼弾'.toBase64(); // 5bCP6aO85by+ '小飼弾'.toBase64(true); // 5bCP6aO85by- '小飼弾'.toBase64URI(); // 5bCP6aO85by- 'ZGFua29nYWk='.fromBase64(); // dankogai '5bCP6aO85by+'.fromBase64(); // 小飼弾 '5bCP6aO85by-'.fromBase64(); // 小飼弾 }TypeScript 2.0 type definition was added to the DefinitelyTyped repository.
$ npm install --save @types/js-base64Suppose you have:
var pngBase64 = "iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAQAAAC1HAwCAAAAC0lEQVR42mNkYAAAAAYAAjCB0C8AAAAASUVORK5CYII="; Which is a Base64-encoded 1x1 transparent PNG, DO NOT USE Base64.decode(pngBase64). Use Base64.atob(pngBase64) instead. Base64.decode() decodes to UTF-8 string while Base64.atob() decodes to bytes, which is compatible to browser built-in atob() (Which is absent in node.js). The same rule applies to the opposite direction.
