1. This app gets the balance of a crypto wallet from the blockchain and calculates the current market value.  This was my first app to pull data from the blockchain.  I also used a .env file to protect addresses/api keys/and node points.

This script showcases how to get data from the blockchain while protecting sensitive information

To make this work git clone this repository:

1. npm install web3   https://web3js.readthedocs.io/en/v1.3.4/

2. npm install node-fetch   https://github.com/node-fetch/node-fetch

3. npm install dotenv   https://github.com/motdotla/dotenv

4. code .env and give values to the variables as you see in the .env_example.  Add the .env to your .gitignore file

5. I have node 15 globally installed. You may need to npm i -y or npm init if you have issues with any of the dependencies.  Also try to close your text editor and reopen it.  I work with VS Code with files on Dropbox switching between 2 computers and have no issues.

6. Finally, you need to verify the returned object structure on your API call from wherever you're getting the current price info. Then update/change the reference to symbolData.price on line 29 if needed.

The one I used looks like this:

{ exchange: 'gdax',

  pair: 'linkusd',

  price: 17.19823,

  ask: 17.20994,

  bid: 17.19823 }
