Development

Install dependencies

npm i

Set up environment variables

Copy the .env.local.example file in this directory to .env.local (which will be ignored by Git):

cp .env.local.example .env.local

Then, open .env.local and add the missing environment variables:

NEXT_PUBLIC_PORTIS_APP_ID - Portis app id (get it from portis.io)
NEXT_PUBLIC_BN_ONBOARD_API_KEY - Blocknative Onboard API key (get it from blocknative.com)
NEXT_PUBLIC_INFURA_PROJECT_ID - Infura project id (get it from infura.io)

Run

npm run dev

Open http://localhost:3000 to view it in the browser.

Build

npm run build
npm start

End-2-End testing

In order to run fully automated end-2-end (e2e) tests Kwenta uses Synpress (a wrapper around Cynpress).

Constraints

The current e2e tests are written to be run on Optimistic Kovan using Chrome as the browser.

Setup

Download and install Google Chrome
Setup a test wallet on Optimistic Kovan and fund it with plenty of ETH (to pay for gas) and sUSD
Prior to running the tests you must set the environment variables below in the shell from which npm is started. Unfortunately, at this time other methods to set said environment variables (eg. through .env.local) don't work in conjunction with Synpress.

PRIVATE_KEY=<INSERTPRIVATEKEY>
NETWORK_NAME=OptimisticKovan
RPC_URL=https://kovan.optimism.io
CHAIN_ID=69
BLOCK_EXPLORER=https://kovan-optimistic.etherscan.io
IS_TESTNET=true

Bash convenience script for setting up the environment

A Bash convenience script has been made available here.

Open bash
Copy the private key of the test wallet into the file SYNPRESS_PRIVATEKEY into the same folder location as the script. While using this method, please don't forget to update your .gitignore file to prevent your private key to be leaked.
Run the following command source ./synpress-envsetter.sh

Run the tests

npm run build
npm start
npm run test:e2e:only:tests
