Nimiq Identicons
SVG+JS Identicons designed to run in browsers and NodeJS. The library is heavily optimized for performance.
See the Identicons in action here.
Installation
Nimiq Identicons can be used in both browsers and NodeJS:
Browsers
You can either use the Identicons script already bundled with the image data (default), or with an external SVG file which is loaded separately.
The Identicons script is provided as an ES6 module and needs to be import
ed
into module scripts or used with build systems such as Webpack and Rollup:
npm install --save @nimiq/identicons
oryarn add @nimiq/identicons
import Identicons from '@nimiq/identicons'
- See how to use it under Usage
To use the other version of the library, which loads the image data separately,
you have to import Identicons from '@nimiq/identicons/dist/identicons.min.js'
instead.
Additionally you have to make sure that the identicons.min.svg
file included in the
dist
directory of this package is made available to website visitors.
Then specify the path where the library can find this SVG file, either by setting
Identicons.svgPath = '/public/path/to/identicons.min.svg'
or in the global scope with
window.NIMIQ_IDENTICONS_SVG_PATH = '/public/path/to/identicons.min.svg'
.
Note: Besides installing the package yourself, you can also use
a npm-enabled CDN:
import Identicons from https://unpkg.com/@nimiq/[email protected]/dist/identicons.bundle.min.js
.
NodeJS
For NodeJS a CommonJS module is provided, which can simply be installed and used by doing:
npm install --save @nimiq/identicons
oryarn add @nimiq/identicons
const Identicons = require('@nimiq/identicons').default
(the.default
is important!)- See how to use it under Usage
If you are using a version of NodeJS with
import
enabled, or are using an ES6 loader such asesm
orbabel-register
, you can just doimport Identicons from '@nimiq/identicons'
for step 2.
Usage
All methods generating identicons are async and return promises.
Get a raw SVG text string:
const svg = await Identicons.svg(text)
Get a SVG data url string (the one starting with data:image/svg+xml;base64,...
),
which can be set as img.src
:
const dataUrl = await Identicons.toDataUrl(text)
Render an identicon SVG into the DOM (only in browsers!):
await Identicons.render(text, element)
Get an <img>
DOM node (only in browsers!):
const img = await Identicons.image(text)
You can generate a placeholder icon with these (sync) methods:
// Placeholder SVG:
const svg = Identicons.placeholder(color = '#bbb', strokeWidth = 1)
// Placeholder data url:
const dataUrl = Identicons.placeholderToDataUrl(color = '#bbb', strokeWidth = 1)
// Render placeholder SVG into `element`:
Identicons.renderPlaceholder(element, color = '#bbb', strokeWidth = 1)
