Installation

$ yarn add ecb-euro-exchange-rates

Usage

TS typings are available and you’ll get auto-completion for the supported currencies.

import * as exchangeRates from 'ecb-euro-exchange-rates';

const result = await exchangeRates.fetch();
console.log('Last update: ' + result.time);
console.log('USD: ' + result.rates.USD);

Historic rates are available via fetchHistoric90d (fetches previous 90 days) and fetchHistoric (fetches all rates back to 1999).

Development

Use Volta.

Install NPM dependencies with yarn.

To execute the tests, run yarn test.

For the best development experience, make sure that your editor supports ESLint and EditorConfig.

Linting of code and commit message happens on commit via Husky.

Releasing to NPM

Commit all changes and run the following:

$ npm login
$ yarn version --<update_type>
$ npm publish

… where <update_type> is one of patch, minor, or major. This will update the package.json, and create a tagged Git commit with the version number.
