vagueTime.js

A tiny JavaScript library that formats precise time differences as a vague/estimated time, e.g. '3 months ago', 'just now' or 'in 2 hours'.

Installation

Node.js

npm install vague-time

Browser

To use vagueTime.js in a browser environment, you can either clone the git repository like so:

git clone [email protected]:philbooth/vagueTime.js.git

Or use one of the growing number of package managers, such as Jam, Ender (the package name for both is 'vague-time'), Bower ('vagueTime.js') or Component ('philbooth/vagueTime.js').

Usage

Loading the library

Node.js

var vagueTime = require('vague-time');

Browser

<script type="text/javascript" src=".../vagueTime.js/src/vagueTime.min.js"></script>

Calling the library

vagueTime.js exports a single public function, get, which returns a vague time string based on the argument(s) that you pass it.

The arguments are passed as properties on a single options object. The optional property from is a timestamp denoting the origin point from which the vague time will be calculated, defaulting to Date.now() if undefined. The optional property to is a timestamp denoting the target point to which the vague time will be calculated, defaulting to Date.now() if undefined. The optional property units is a string, denoting the units that the from and to timestamps are specified in, either 's' for seconds or 'ms' for milliseconds, defaulting to 's' if undefined.

Essentially, if to is less than from the returned vague time will indicate some point in the past. If to is greater than from it will indicate some point in the future.

Examples

vagueTime.get({
    from: 60,
    to: 0
}); // returns '1 minute ago'

vagueTime.get({
    from: 0,
    to: 60
}); // returns 'in 1 minute'

vagueTime.get({
    from: 7200,
    to: 0
}); // returns '2 hours ago'

vagueTime.get({
    from: 0,
    to: 7200
}); // returns 'in 2 hours'

vagueTime.get({
    from: 345600,
    to: 0
}); // returns '4 days ago'

vagueTime.get({
    from: 0,
    to: 345600
}); // returns 'in 4 days'

vagueTime.get({
    from: Date.now(),
    units: 'ms'
}); // returns 'now'

Development

Dependencies

The build environment relies on Node.js, NPM, Jake, JSHint, Mocha, Chai and UglifyJS. Assuming that you already have Node.js and NPM set up, you just need to run npm install to install all of the dependencies as listed in package.json.

Unit tests

The unit tests are in test/vagueTime.js. You can run them with the command npm test or jake test.
