Command line tool handle blockchain log file

CLI Application

Idea

• Write command application base on commander package
• Parse and store data in a sufficient data-structure (pre-calculate final balance, by day volatile)
• Use stream API to handle data row one by one (cause data file is large)
• Use lokijs (embed database) to deal with heap size exceed issue

Feature

• Node.js
• Typescript
• commander
• axios
• lokijs
• husky, prettier, lint-staged

Install && set up

yarn install
cp .env.example .env
export NODE_OPTIONS="--max-old-space-size=8192"

Set up environment variable LOG_FILE_PATH and CRYPTO_EXCHANGE_API_KEY

CRYPTO_EXCHANGE_API_KEY=e4ce426fb741a048d492c1b49274ece10cf51cb8c11ebe33f9f8396bab312a34
