A quick way to fetch total supply for your Ethereum based ERC-20 smart contract token via web3 and output it to body. This example comes with Datamine (DAM) & FLUX ERC-777 tokens pre-configured.

Installation

• Get Microsoft Azure account
• Get Visual Studio Code & install Azure Functions extension
• You will need web3 provider (ex: infura.io) and set it as a "web3" prop in local.settings.json Values section (This is Application Settings in prod)

Usage

• npm run watch in one terminal (This will automatically compile Typescript on Changes)
• npm run start this will run a function in an emulator (look at output for url)
• Navigate to /api/totalsupply?token=dam for example of Datamine ERC-777 Token. This will output total supply of the token from the smart contract value.
