js-climacell-api is a JavaScript wrapper around the ClimaCell API (v4) that can be used in both NodeJS and Browser environments

Installation

This package is Typescript ready

npm i js-climacell-api

How to use it

The library is a default export.

Browser

To use it browser, you need to use the code from browser.js file.

<script src="path-to-local-library/browser.js"></script>

or via CDN

<script src="https://unpkg.com/js-climacell-api@X.Y.Z/browser.js"></script>

Where X.Y.Z represents the library version.

In this scenario, the library will be bound to the global window object with the property ClimaCellAPI.

window.ClimaCellAPI or simple ClimaCellAPI can be used to access the library.

If you have a toolchain available you can use an import statement.

import ClimaCellAPI from 'js-climacell-api/browser';
const ClimaCellWrapper = require('js-climacell-api/browser');

Because is a default export, here you can import it with what name you want


Node

For NodeJS environment, just replace browser with node

import ClimaCellAPI from 'js-climacell-api/node';

Methods

The object imported is a class that will expose the following methods:

static async requestData(options: QueryBuilderOptions):Promise<any> {}

Where options is an object of form:

interface QueryBuilderOptions {
  [param: string]: string | number | string[] | number[];
}

This static method can be used to compute an URL and send a GET request to https://data.climacell.co/v4/timelines.

The values from options object will be transformed into query parameters.

Example

await ClimaCellAPI.requestData({
  apikey: '23',
  location: `1.2%2C2.2`,
  fields: ['temperature', 'humidity'],
});

will result in a request to the following URL:

https://data.climacell.co/v4/timelines?apikey=23&location=1.2%2C2.2&fields=temperature&fields=humidity

The result will be exactly the raw response from the API.

The purpose of this method is to give you full controll over the request URL and help you easily compute it and acquire timeline data from the API.

Don't forget to add your apikey!


For the following methods the class must be instantiated with the following constructor.

constructor(apiKey: string, coordinates: GeoCoordinates) {}

Where coordinates has the following format:

export type GeoCoordinates = [string | number, string | number]; //latitude & longitude

Example

import ClimaCellApi from 'js-climacell-api/dist/node';

const API_KEY = '';
const LAT = '';
const LON = '';

const hometownMonitor = new ClimaCellApi(API_KEY, [LAT, LON]);

The available methods are the following:

async current(options: TimelinesOptions): Promise<any> {}
async perMinute(options: TimelinesOptions): Promise<any> {}
async per5Minutes(options: TimelinesOptions): Promise<any> {}
async per15Minutes(options: TimelinesOptions): Promise<any> {}
async per30Minutes(options: TimelinesOptions): Promise<any> {}
async perDay(options: TimelinesOptions): Promise<any> {}

Each method will return the raw response from the API.

The types:

export enum UnitType {
  metric = 'metric', // International System of Units
  imperial = 'imperial', // Imperial and US customary measurement systems
}

export interface Availability {
  start?: string | number;
  end?: string | number;
}

export interface TimelinesOptions {
  fields: string[];
  availability?: Availability;
  units?: UnitType;
  timezone?: string;
}

availability?: Availability matches the availability mentioned in the documentation and represents the interval of the data requested

timezone?: string - Timezone names follow the IANA Time Zone Database format

fields represents an array with the fields you are intersted in (Core-Air Quality-Pollen-Fire-Precipitation)

Examples

(async () => {
  const hometownMonitor = new ClimaCellAPI('api_key', [45.6427, 25.5887]);

  await hometownMonitor.perMinute({
    fields: ['temperature', 'particulateMatter25'],
    units: 'imperial',
  });
})();

Will result in a request to the following URL.

https://data.climacell.co/v4/timelines?timesteps=1m&fields=temperature&fields=particulateMatter25&units=imperial&apikey=api_key&location=45.6427,25.5887

availability

await hometownMonitor.perMinute({
  fields: ['humidity'],
  availability: {
    start: '-1h',
    end: '2h',
  },
});

The above call will request data with a time interval of 1m, but starting with 1 hour behind the current time and up to 2 hours in front.

The accepted values for availability.start and availability.end are the time formats accepted by ms module.

The next call will request data starting 5 minutes in the future from the current time.

await hometownMonitor.perMinute({
  fields: ['humidity'],
  availability: {
    start: 1000 * 60 * 5,
  },
});

If you want to use an exact date, then you can implement it as in the following example:

const specificDate = '2021-01-30T12:07:01.939Z';

await hometownMonitor.perMinute({
  fields: ['humidity'],
  availability: {
    start: new Date(specificDate).getTime() - Date.now(),
  },
});
