DEPRECATED: Javascript Developer library for interacting with Dharma Protocol

NOTE: dharma.js is deprecated and no longer in active maintenance. Please email [email protected] if you have any questions or concerns

---

Hello, dharma.js!

This repository contains the dharma.js client application development libraries. dharma.js makes it easy for developers who may not be deeply familiar with smart contract development to interact with the various components of Dharma protocol and build hyper-flexible lending applications.

For more information, please check out the Dharma Developer Portal.

Getting Started with Dharma.js

Installing Dharma.js

Add Dharma.js to your project using yarn:

yarn add @dharmaprotocol/dharma.js

Alternatively, add Dharma.js to your project using npm:

npm install @dharmaprotocol/dharma.js --save

Importing Dharma.js

Include Dharma.js in your project code using ES6 style imports (recommended):

import { Dharma } from "@dharmaprotocol/dharma.js";

Alternatively, include Dharma.js in your project code using require syntax:

const { Dharma } = require("@dharmaprotocol/dharma.js");

Instantiating Dharma.js

In order to instantiate Dharma.js, you need to specify a web3 provider.

The web3 provider can either be instantiated directly, or pulled from the browser's window object.

Instantiating the web3 provider directly

You'll want to instantiate a web3 provider directly if you're:

• running Dharma.js on a backend
• working with a local blockchain

You'll first import Dharma and Web3 from the Dharma.js package:

import { Dharma, Web3 } from "@dharmaprotocol/dharma.js";

Assuming you're running a local blockchain on localhost port 8545, you'd specify the provider as follows:

const host = "http://localhost:8545";
const provider = new Web3.providers.HttpProvider(host);

You'd then pass the above provider to the Dharma constructor, using JavaScript's new operator to construct an instance of Dharma connected to your local blockchain:

const dharma = new Dharma(provider);

Pulling the web3 provider off the browser's window object

If the user is interacting with your dApp via a web3 wallet (e.g., MetaMask, Coinbase Wallet, etc.), you can pull the web3 provider from the browser's window object and pass that to the Dharma constructor:

const provider = window.web3.currentProvider;

const dharma = new Dharma(provider);
