Introduction

This is a script that gets the cosmos.directory data from GitHub and converts it into a JSON file, stores it on S3 and invalidates the cloudfront cache.

The generated data is of the following type -

import type { ChainInfo } from '@keplr-wallet/types'

type GeneratedData = {
  mainnet: Record<string, ChainInfo>
  testnet: Record<string, ChainInfo>
}
