A generic identity icon that renders Substrate based chains identicons for html/javascript frontend applications.
This project is based on the polkadod-angular-identicon
Run npm i live-server -g to install live-server globally
The simplest way to use the component is to download it from npm
We assume you have npm and node.js installed in your environment.
There is a ready to use project or clone this pwi-example project.
after cloning the project type npm i to download the dependencies and live-server to run the example.
Another way also is to create a project from scratch with npm init and an empty html file.
- create a folder with a name of your choice for example :
pwi(like polkadot-web-identicon 😎)
cd into the pwi (or the one you created) folder.
Type npm init to create the package.json file that will allow us to download packages from npm.
For simplicity sake, type enter for each question and at the end the package.json file should be created.
Create an index.html file that will contain the html and javascript code and past the following html snippet.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Testing polkadot-web-identicon</title>
</head>
<body>
</body>
</html>Now we can install the polkadot-web-identicon package from npm with :
npm i polkadot-web-identicon
After the installation completed we are ready to use the package we just need to do two things:
- import the component library code files
- call the component and use it with our parameters
These are the attributes that we can pass to the polkadot-web-identicon tag
address : the Substrate blockhain based address to pass as parameter
theme : the theme we want to display ( polkadot, beachball, jdenticon)
size : the size we want our identicon to be.
Our final structure in the index.html file will look like this:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">

</html>you can run live-server under the pwi or your project to see the render icons
or open the index.html file on browser
See inside pwi folder to see a ready to use example.
on the terminal type npm i and live-serverto run the example.
For those who wants to build or tweak the library see BUILD.md file under documentation.
Improvements are on the way !!! Happy coding 😎!!!
