Let's build a token explorer - Nodejs, TypeScript, GraphQL, web3js #crypto

Let's build a GraphQL API to source data on any ERC-20 token such as price, total supply, etc directly from the blockchain. This is Part 1 of a planned 2 part series, covering the backend server. In Part 2 we will use React and the API we build in this video to create the frontend for our token explorer.
