The CasperHolders website / mobile app use this library to handle any interaction with the CasperNetwork.

It contains a huge portion of the website & mobile app logic.

API Documentation

npm install @casperholders/core


yarn add @casperholders/core

Example usage

import { ClientCasper } from '@casperholders/core';

export default new ClientCasper('rpcurl');

When you use this lib in module mode you must transpile it. Example with a vue project:

module.exports = {
  // ...
  transpileDependencies: [
  // ...

You can find some example of the lib in the tests folders.
However, keep in mind this is a utility lib.
You will have to implement some abstracts class in your project if needed like the KeyManager.

We don't test abstracts / results / errors classes because they don't own any logic.
We don't test the implementation of the CasperSigner because it requires full access to a browser test suite and the extension.
We assume the Casper Signer JS SDK is battle tested to interact with the Casper Signer extension
