Getting set up

To start developing on the Yearn Finance Safe app, first clone this repository and enter the new directory.

git clone https:/TomAFrench/yearn-safe-app.git
cd yearn-safe-app

Before getting started you will need to create a .env file. We have provided .env.example as a template.

cp .env.example .env

Finally install any dependencies and start the dev server

yarn install
yarn start

The app will then be hosted on http://localhost:3002. By default the app will expect an injected web3 provider such as metamask; if you want to interact with the app through the Gnosis UI you'll need to set the REACT_APP_LOCAL_WEB3_PROVIDER environment variable to false.

react-app-rewired

In order to allow the Gnosis Safe UI to access the app while it's running on localhost we need to edit the headers on the dev server (node_modules/react-scripts/config/webpackDevServer.config.js) to avoid CORS issues:

headers: {
    "Access-Control-Allow-Origin": "\*",
    "Access-Control-Allow-Methods": "GET",
    "Access-Control-Allow-Headers": "X-Requested-With, content-type, Authorization"
},

We automate injecting these headers in to the server config through react-app-rewired.
