Dependencies
CoinDesk API client for node.js uses a number of open source projects to work properly:
- @hapi/joi - The most powerful schema description language and data validator for Javascript
- axios - Promise based HTTP client for the browser and node.js
- node-fetch - A light-weight module that brings window.fetch to node.js
- winston - A logger for just about everything
And of course CoinDesk API client for node.js itself is open source with a public repository on GitHub.
Installation
Install the npm package from npmjs.com with the command:
npm install --save coindesk
Quick Start
A series of simple examples for Bitcoin price fetching:
Get currentprice price for Bitcoin in json format
const { CoindeskAPIClient } = require('coindesk');
const apiClient = CoindeskAPIClient.start('currentprice');
const response = apiClient.get()
.then(response => response)
.catch(err => console.error(err));
Get currentprice price for Bitcoin in other currency than USD
const { CoindeskAPIClient } = require('coindesk');
const apiClient = CoindeskAPIClient.start('currentprice', { currency: 'EUR' });
const response = apiClient.get()
.then(response => response)
.catch(err => console.error(err));
Get historical price for Bitcoin in json format
const { CoindeskAPIClient } = require('coindesk');
const apiClient = CoindeskAPIClient.start('historical');
const response = apiClient.get()
.then(response => response)
.catch(err => console.error(err));
Get historical price for Bitcoin providing optional parameters
const { CoindeskAPIClient } = require('coindesk');
const apiClient = CoindeskAPIClient.start('historical', { currency: 'EUR', for: 'yesterday' });
const response = apiClient.get()
.then(response => response)
.catch(err => console.error(err));
Get raw http response for either currentprice or historical (defaults to false)
const { CoindeskAPIClient } = require('coindesk');
const apiClient = CoindeskAPIClient.start('currentprice');
const response = apiClient.get(raw=true)
.then(response => response)
.catch(err => console.error(err));
Get supported currencies to fetch Bitcoin price in
const { CoindeskAPIClient } = require('coindesk');
const apiClient = new CoindeskAPIClient();
const supportedCurrencies = apiClient.getSupportedCurrencies();
Examples for CoinDesk API response parsing (currentprice or historical):
Parse and validate fetched Bitcoin price response
const { CoindeskAPIClient, CoindeskAPIResponse } = require('coindesk');
const dataType = 'historical';
const apiClient = new CoindeskAPIClient(dataType);
const response = apiClient.get(raw=true)
.then(response => CoindeskAPIResponse.parse(response, dataType))
.catch(err => console.error(err));
Get info from parsed Bitcoin price response
const { CoindeskAPIResponse } = require('coindesk');
const parsedResponse = CoindeskAPIResponse.parse(response);
const apiResponse = parsedResponse.response;
const jsonResponse = parsedResponse.JSONResponse;
const items = parsedResponse.responseItems;
const bpi = parsedResponse.getResponseItem('bpi');
