Superhero Utils

Installation

You can get it as npm package or from the unpkg.com.

With npm

• run $ npm install @aeternity/superhero-utils --save in the root or your project
• import this package by import superheroUtils from '@aeternity/superhero-utils';

With unpkg.com and <script> tag

Add this to your website's HTML:

<script src="https://unpkg.com/@aeternity/[email protected]/dist/index.js"></script>

This will define superheroUtils in the global scope.

With custom styles

You can import and process styles manually by importing dist/index.css and dist/index-without-styles.js separately. Or even you can don't import styles at all, and write your own instead.

React and Vue versions

By default dist/index.js is imported, instead of it, you can import a specific version for React or Vue by importing dist/react-without-styles.js or dist/vue-without-styles.js accordingly. The framework-specific version contains all features available in the default one plus specific for particular framework wrappers.

superheroUtils.createButtonByDiv

The same function as the previous one except that the first argument should be an instance of HTMLDivElement. The button content will be added to that node instead of the DOM node replacing. The function with this interface simplifies integration into Frontend frameworks like Vue and React.

The component that is compatible with the corresponding framework. Accepts the same properties as superheroUtils.createButton's options.

Example

<Button size="large" account="example.chain" url="https://example.com" />

Paywall (superheroUtils.ensurePaid)

This function asks the user to send a tip to the specified page. It won't ask to send a tip if it was sent before using the current browser. The function accepts options object.
