Development

Local setup

Clone this repository, install deps and create an .env.local file by running:

yarn
cp .env.example .env.local

Adjust values in the created .env.local accordingly.

Start dev server

Start the frontend with a dev server by running:

yarn start

Build production bundle

yarn build

Run unit tests

yarn test

Run e2e tests

Our e2e tests rely on a local hardhat node that forks mainnet. First, set the env var HARDHAT_INFURA_ID in your .env file and make sure to run such a node before starting the tests:

yarn hardhat:node

We use cypress for handling e2e tests. To run the tests locally, first make sure to have a local dev sever running:

yarn start

If you want to start the cypress UI run:

yarn cypress:open

If you want to run the tests from the CLI, run:

yarn cypress:run

Per default cypress expects the frontend running on http://localhost:3000. To change that run:

CYPRESS_BASE_URL=http://localhost:3333 yarn cypress:run

Important CSS values

Z-index

Navbar - 1000 Toast - 99999 Modal - 99998
