currency-api

This is cloudflare worker based API that acts like proxy for openexchangerates api, that:

1. caches /history response for queried date into Cloudflare KV (you can easily tweak caching frequency by editing date format — by default it is one response per day)
2. allows to change base currency

Example request:

/?date=YYYY-MM-DD&base=UAH

Development

1. Install dependencies with pnpm i
2. Add your OPENEXCHANGERATES_APP_ID to .dev.vars
3. Add wrangler.toml and fill it like shown in wrangler.toml.example

Disable local mode if you want to put values into _preview KV

Production

1. Run pnpm wrangler secret put to add OPENEXCHANGERATES_APP_ID with your openexchangerates App ID
2. Add wrangler.toml and fill it like shown in wrangler.toml.example

Then run pnpm run deploy to publish changes
