gatsby-source-exchange-rates-api

Description

A Gatsby source plugin for retrieving data from the exchangeratesapi.io API.

How to install

Install the package as a dependency

yarn add gatsby-source-exchange-rates-api

Add the plugin to your gatsby-config.js file

// gatsby-config.js
{
  plugins: [
    {
      resolve: 'gatsby-source-exchange-rates-api',
    }
  ]
}

How to query data

You can select the endpoint to fetch from by specifying endpoint in the plugins options object. The default is the endpoint latest. You can also specify query parameters as a query object (default is no query).

Exchange Rates API documentation: (Github) (Website)

// gatsby-config.js
{
  resolve: 'gatsby-source-exchange-rates-api',
  options: {
    endpoint: 'history', // (optional) default is "latest"
    query: { // (optional)
      base: 'SEK',
      symbols: 'EUR,USD',
      start_at: '2019-02-01',
      end_at: '2019-02-03',
    },
  }
}

If you use the default endpoint latest you will get one node with the latest rates. If you use the endpoint history there will be multiple rates returned as an array instead.

Latest endpoint usage example

// Get the latest rates
useStaticQuery(graphql`
  query {
    exchangeRates {
      id
      date
      USD
    }
  }
`)

History endpoint usage example

// Get an array of history rates
useStaticQuery(graphql`
  query {
    allExchangeRates {
      edges {
        node {
          id
          date
          USD
          EUR
        }
      }
    }
  }
`)
