Stack: React, Hasura graphql server & vercel serverless functions

• NodeJS v14
• Yarn
• Docker
• Vercel CLI

Quick Start

• yarn install
• yarn setup
  • init git submodules & hardhat dependencies
• cp .env.example .env
  • Set HARDHAT_OWNER_ADDRESS and LOCAL_SEED_ADDRESS to your local dev wallet
• yarn docker:start - Start Hasura and postgres
  • Clear the data stored in the docker volumes: yarn docker:clean
• yarn db-seed-fresh - Seed the db w/ dummy data
• yarn start
  • Runs React and the serverless functions in api/
• Go to http://localhost:3000 and start giving!

If you want to hack on end-to-end tests, or see why one might be failing, see our cypress README.

Frontend

More detailed guidelines coming soon.

When writing new frontend components, please use Stitches instead of Material-UI. See:

• Intro video with the author of Stitches
• stitches.config.ts
• src/ui, where we have a set of basic components
  • This folder is for simple HTML tags wrapped with styled; components with logic and/or state should still go in src/components, or in a subfolder named for the main component they belong to.

Key libraries

• Create React App
• Stitches
• ethers
• Luxon
• Sentry (error reporting)
• d3-force-3d
  • See forked canvas-color-tracker for brave compatibility
• Recoil - deprecated
• Material UI - deprecated

Hasura

Hasura automagically creates a GraphQL API atop our postgres db. We use it to apply migrations and manage metadata. Perhaps, the easiest way to get a feel is start the app and run yarn hasura console.

Working with the schema

• yarn hasura console to modify and explore the database
• yarn generate after schema changes to codegen zeus & react-query libs
  • Requires yarn start to be running

Updating migrations / metadata

If you pull in any new changes to the schema, your local Hasura instance might start complaining about metadata inconsistency. In order to apply the new migrations / metadata to your local instance, run the following commands:

yarn hasura migrate apply
yarn hasura metadata apply

Alternately, you can just run yarn docker:stop && yarn docker:start and Hasura will apply the migrations/metadata automatically.

Previewing changes

Any changes you make in yarn hasura console will be reflected in your local hasura directory as migrations or metadata. In the feature branch a clone of the staging database will be created with the changes.

These will be applied to the production instance once the PR is merged.

Hardhat

Hardhat is used with typechain to generate TypeScript bindings for the smart contracts, which are in this repo as a git submodule at hardhat/contracts.

• Set ETHEREUM_RPC_URL in .env
  • From Infura project id: Infura & create new project
  • Needs to have access to archive data
• ./scripts/rebuild_hardhat.sh - Rebuild the generated code
• yarn test - Run tests
  • make sure HARDHAT_FORK_BLOCK is set (13500000 is a good value) and ETHEREUM_RPC_URL points to an archive node

Gitpod (experimental)

For an easy quick start, launch a Gitpod development version of the development environment.

Open Gitpod in "Open in VS Code on Desktop", then verify the ports 3000, 8080 and 4566 are being forwarded by VS Code in the "Ports" tab of VS Code. You should then be able to load the app at localhost:3000.

If you want to set a custom .env file for your personal settings and address, edit .env and then save it to your Gitpod profile with

gp env DOTENV="$(base64 .env | tr -d '\n')"

See .gitpod.yml for details on how Gitpod works.

Troubleshooting

• Cannot start service app: error while creating mount source path Try restarting Docker Desktop

• TypeError: Cannot read properties of undefined (reading 'replace') You need to configure a local .env file with some private variables. Ask someone for these.
