Meteor-Gravatar

Easy Gravatar for your Meteor App

Dependencies

jparker:crypto-md5

Install

Inside your project folder run

$ meteor add jparker:gravatar

Usage

The following methods under the Gravatar namespace will be available on both the client and server:

cleanString(string): Remove starting and trailing whitespaces and lowercase the input string
isHash(string): check if a string matches the MD5 format: 32 chars string containing letters from a to f and digits from 0 to 9
hash(string): takes an input and runs it through CryptoJS.MD5 to get the MD5 hash back.
imageUrl(string, object): computes the URL for the avatar, given an email or an MD5 hash and a set of options to be passed to the Gravatar API.

See the documented code for more details.

See the test file for more examples of input -> output.

Example

var email = 'email@example.com';
var options = {
    secure: true // choose between `http://www.gravatar.com`
                 //            and `https://secure.gravatar.com`
                 //            default is `false`
};

var md5Hash = Gravatar.hash(email);
// 5658ffccee7f0ebfda2b226238b1eb6e

var url = Gravatar.imageUrl(email, options);
// https://secure.gravatar.com/avatar/5658ffccee7f0ebfda2b226238b1eb6e

var url2 = Gravatar.imageUrl(md5Hash, options);
// https://secure.gravatar.com/avatar/5658ffccee7f0ebfda2b226238b1eb6e

options may contain key:value pairs of parameters to be added to the URL. For a list of parameters available, see Gravatar's documentation

// Example:
var url = Gravatar.imageUrl('email@example.com', {
    size: 34,
    default: 'mm'
});
// http://www.gravatar.com/avatar/5658ffccee7f0ebfda2b226238b1eb6e?size=34&default=mm

Normalizing email addresses

Some users prefer to include address tags in their email when they sign up for services - for example joe+games@gmail.com, or joe+thisnewservice@fastmail.com. Most of the time they won't bother setting a gravatar for the new email address, so you'd normally get a palceholder image or 404 from Gravatar.

To address this problem, you can look at idorecall:email-normalize.

Previously this was included but as email-normalize seems to be unmaintained I decided to drop the dependency and give full controll back to the developer. I believe a package like this one should do one thing well and one thing only.
