Getting Started *************** The ethers.js library is a compact and complete JavaScript library for Ethereum. ----- Installing in Node.js ===================== From your project directory:: /Users/ricmoo/my-project> npm install --save ethers And from the relevant application files:: var ethers = require('ethers'); ----- Including in Web Applications ============================= For security purposes, it is usually best to place a copy of `this script`_ on the application's server, but for a quick prototype using the Ethers CDN (content distribution network) should suffice:: ----- .. _npm is installed: https://nodejs.org/en/ .. _this script: https://cdn.ethers.io/scripts/ethers-v3.0.min.js
