identicon-browserify

Identicon generator for Node.js and now the browser!

Difference

This fork allows you to use create identicons in node and the browser with browserify. This also has a breaking change in signature, which no longer returns a buffer but instead a data uri. To keep compatibility between both browser and node versions of canvas, toDataURL is used instead to generate identicons.

There is also an added an extra option to set a different mime type other than PNG (for example: JPEG ('image/jpeg') or the newer WebP ('image/webp')). PNG is used by default and is guaranteed by spec, however extra mime types are generally supported depending on canvas implementation.

Example

var identicon = require('identicon-browserify')
 
// Asynchronous API
identicon.generate({ id: 'ajido', size: 150, type: 'image/jpeg' }, function(err, uri) {
    if (err) throw err;
 
    var image = new Image
    image.src = uri // if your canvas implementation supports JPEG creation, then this will likely contain a (data:image/jpeg) header. 
})
 
// Synchronous API
var uri = identicon.generateSync({ id: 'ajido', size: 40 }) // generates PNG identicon by default

Asynchronous API

.gen

.generate(opts, callback)

{
  opts: Object,
  callback: Function
}

.gen

.generate(id, size, [mimetype], callback)

{
  id: String,
  size: Number,
  mimeType: String,
  callback: Function
}

Synchronous API

.genSync

.generateSync(opts)

{
  opts: Object
}

.genSync

.generateSync(id, size, [mimeType])

{
  id: String,
  size: Number,
  mimeType: String
}

Please note mimeType is always optional. Defaults to PNG format. See the example for more details.
