    Nimiq Identicons

    Nimiq Identicons Example 1

    SVG+JS Identicons designed to run in browsers and NodeJS. The library is heavily optimized for performance.

    See the Identicons in action here.


    Nimiq Identicons can be used in both browsers and NodeJS:


    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 imported into module scripts or used with build systems such as Webpack and Rollup:

    1. npm install --save @nimiq/identicons or yarn add @nimiq/identicons
    2. import Identicons from '@nimiq/identicons'
    3. 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/identicons@1.4/dist/identicons.bundle.min.js.


    For NodeJS a CommonJS module is provided, which can simply be installed and used by doing:

    1. npm install --save @nimiq/identicons or yarn add @nimiq/identicons
    2. const Identicons = require('@nimiq/identicons').default (the .default is important!)
    3. 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 as esm or babel-register, you can just do import Identicons from '@nimiq/identicons' for step 2.


    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)
