README

caniuse-cmd
===========

Just what you've always wanted, it's a `caniuse` command line tool!
All the power of [caniuse.com](http://caniuse.com) with none of the nice UI or interactivity!

How do?
-------

Install with `npm install -g caniuse-cmd`.

Then type things like this:

```
$ caniuse websockets
Web Sockets ✔ 85.22% ◒ 1.35% [W3C Candidate Recommendation]
Bidirectional communication technology for web apps #JSAPI

IE ✘ 5.5+ ✔ 10+
Firefox ✘ 2+ ◒ 4+¹ ◒ 6+ᵖ² ✔ 11+
Chrome ◒ 4+¹ ◒ 15+² ✔ 16+
Safari ✘ 3.1+ ◒ 5+¹ ◒ 6+² ✔ 7+
Opera ✘ 9+ ◒ 11+¹ ✔ 12.1+

¹Partial support refers to the websockets implementation using an older version of the protocol and/or the
implementation being disabled by default (due to security issues with the older protocol).
²Partial support refers to lacking support for binary data.
```

(The output has truly marvellous colours that this markdown is too narrow to contain.)

Or this:

```

```

Woah, that's a lot of options! Can haz config file?
---------------------------------------------------

Yes! You can specify your own defaults by creating a file called `.caniuse.json`
and putting it in your home directory.

For example, if you're primarily interested in mobile browsers two versions back:

```
{
"era": "e-2",
"mobile": true,
"desktop": false
}

```
