The experience of using Node.JS with TypeScript, ts-node, and ESM is horrible.

There are countless guides of how to integrate them, but none of them seem to work.

Here's what worked for me.

Just add the following files and run npm run dev. You'll be good to go!

package.json

from web3 import Web3
from web3.constants import MAX_INT
from web3.middleware import geth_poa_middleware

rpc_url = "" # Polygon rpc url 
priv_key = "" # Polygon account private key (needs some MATIC)
pub_key = "" # Polygon account public key corresponding to private key

chain_id = 137

Project Setup

Create a directory and run the following command.

npm init 

For this tutorial, I will be adding an index.js file to the src folder, and this will be our entry point. Our file directory should look like this.

Visual Regression Testing with Jest

This is a walkthrough of how to set up Visual Regression Testing with Jest for an application created with create-react-app.

The following walkthrough uses React as an example, but the approach should work for any modern frontend library! I assume it can be used with Angular, Vue, Cycle.js and more.

This gist walks you through a create-react-app application as an example of how to set up Visual Regression Testing in Jest using libraries I wrote recently which enable this: jsdom-screenshot, jest-transform-css and jest-transform-file.
