The gitbook install has been incredibly flaky due to it's dependency on npm. This commit simply vendors the node_modules so that each time we build the site the process doesn't have to re-run gitbook install. Signed-off-by: Torin Sandall <torinsandall@gmail.com>
abab
A module that implements window.atob and window.btoa according to the WHATWG spec. The code is originally from w3c/web-platform-tests.
Compatibility: Node.js version 3+ and all major browsers (using browserify or webpack)
Install with npm:
npm install abab
API
btoa (base64 encode)
const btoa = require('abab').btoa;
btoa('Hello, world!'); // 'SGVsbG8sIHdvcmxkIQ=='
atob (base64 decode)
const atob = require('abab').atob;
atob('SGVsbG8sIHdvcmxkIQ=='); // 'Hello, world!'
Valid characters
Per the spec, btoa will accept strings "containing only characters in the range U+0000 to U+00FF." If passed a string with characters above U+00FF, btoa will return null. If atob is passed a string that is not base64-valid, it will also return null. In both cases when null is returned, the spec calls for throwing a DOMException of type InvalidCharacterError.
Browsers
If you want to include just one of the methods to save bytes in your client-side code, you can require the desired module directly.
var atob = require('abab/lib/atob');
var btoa = require('abab/lib/btoa');
Checklists
If you're submitting a PR or deploying to npm, please use the checklists in CONTRIBUTING.md
Remembering atob vs. btoa
Here's a mnemonic that might be useful: if you have a plain string and want to base64 encode it, then decode it, btoa is what you run before (before - btoa), and atob is what you run after (after - atob).
