Today I received an e-mail with the link of this lib and I found it very interesting to share with you.

This tiny lib developed by Brazilians fetch to you the SELIC, IPCA and CDI rates. The lib is compatible with Node.js v12+, Deno v1+ and supports ESImport and CommonJS. The SELIC rate and ICPA rate are fetched from Banco Central do Brasil and the CDI rate is fetched from CETIP. More information about the lib and authors here: npm and Github.

See you later! 😉
