Package Exports

iam-client-lib

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (iam-client-lib) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Getting Started

For development purposes, please follow below steps to integrate the library with your dApps.

Prerequisites

iam-client-lib is written in TypeScript. Make sure to have Node.js (>= v10) installed. Create a folder named iam-client-lib and clone this GIT project.

Also note that having a DID document with a public key is a prerequisite for using iam-client-lib and during initialization the library with attempt to add a public key to the DID document if one doesn't exist. This addition of the public key requires the account to be funded.

Install

Latest stable version

$ npm i iam-client-lib

Prerelease version

$ npm i iam-client-lib@canary

Sample Config for browsers (TypeScript)

import {
  IAM,
  WalletProvider,
  setCacheClientOptions,
  setChainConfig,
  setMessagingOptions,
  MessagingMethod,
} from 'iam-client-lib'

export class App {
    private _iam: IAM;

    constructor() {
      // IAM has builtin default settings for VOLTA CHAIN

      // If you want to change default cache server config or add config for your network
      setCacheClientOptions(1111, {
        url: 'https://some-cache-server.com/',

      // this will show connection modal and authenticate
      const { did, connected } = await this._iam.initializeConnection({
        walletProvider: WalletProvider.MetaMask,
      });

      // after successfully authentication you can retrieve the signer
      const signer = this._iam.getSigner();
    }
