Everest web app

Tools

General front end tooling

• React (using Hooks)
• TypeScript
• Create React App to handle build configuration
• emotion for styling components with css-in-js
• Apollo Client for querying for indexed data from the smart contracts
• React Router v5 for client-side routing
• Rebass for responsive grid and base component library
• GitHub Pages for hosting

Ethereum-related tooling

• web3-react for an abstraction that lets us easily swap in and out web3 providers (MetaMask, WalletConnect, etc.) and a dev-friendly context containing an instantiated ethers.js instance, the current account, and network id available globally throughout the dapp via a React Context.
• ethers.js v4 (with an upgrade to v5 planned soon) for writing data to the contracts
• The Graph for indexing data from the contracts
• MetaMask for an Ethereum account available as a browser extension

Contracts

Tips for local development

To run on a testnet, make a copy of .env.local.example named .env.local, change REACT_APP_NETWORK_ID to "{yourNetworkId}", and change REACT_APP_NETWORK_URL to e.g. "https://{yourNetwork}.infura.io/v3/{yourKey}". Fear not: .env.local is in the .gitignore file, so you won't accidentally commit it.

Available Scripts

In the project directory, you can run:

npm start

Runs the app in the development mode.
Open http://localhost:3000 to view it in the browser.

The page will reload if you make edits.
You will also see any lint errors in the console.

npm test

Launches the test runner in the interactive watch mode.
See the section about running tests for more information.

npm run build

Builds the app for production to the build folder.
It correctly bundles React in production mode and optimizes the build for the best performance.

The build is minified and the filenames include the hashes.
Your app is ready to be deployed!

See the section about deployment for more information.

npm run eject

Note: this is a one-way operation. Once you eject, you can’t go back!

If you aren’t satisfied with the build tool and configuration choices, you can eject at any time. This command will remove the single build dependency from your project.

Instead, it will copy all the configuration files and the transitive dependencies (Webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except eject will still work, but they will point to the copied scripts so you can tweak them. At this point you’re on your own.

You don’t have to ever use eject. The curated feature set is suitable for small and middle deployments, and you shouldn’t feel obligated to use this feature. However we understand that this tool wouldn’t be useful if you couldn’t customize it when you are ready for it.
