@probable-futures/probable-futures-maps

This package empowers developers to seamlessly integrate dynamic and interactive climate maps into their web applications

Installing

Using npm: npm install @probable-futures/probable-futures-maps

Using yarn: yarn add @probable-futures/probable-futures-maps

Functions

generateEmbedMap

Easily embed any Probable Futures map in a website without touching a single line of code. This function can be used to generate embeddable maps as an html-string template.

Params:

  • datasetId (Number): The id of the dataset associated to each map. The list can be found in the docs
  • tempUnit (°C or °F): If the map unit is a temperature unit, eg. "Average Tempareture" map, you can choose the initial unit for the map data. Note that unit can still be changed from the map key
  • scenario (Number): The warming scenario
  • viewState (Object): This is an object which defines the initial view port of the map. The object includes longitude, latitude, and zoom
  • compare (Object): This object can be specified in case the user wants to generate a comparison embeddable map. The object fields are scenarioBefore and scenarioAfter
  • hideControls (Boolean) - default false: Hide the map controls, such as zoom buttons
  • hideMapLegend (Boolean) - default false: Hide the map key
  • hideTitle (Boolean) - default false: Hide the title containing the map name
  • hideResetMapButton (Boolean) - default true: Hide the reset button. This button could be used to reset the map to its original view given the initial long, lat and zoom.

Example:

import { generateEmbedMap } from "@probable-futures/probable-futures-maps";
import * as fs from "fs";

const htmlTemplate = await generateEmbedMap({
  datasetId: 40101,
  viewState: {
    zoom: 4,
  },
  scenario: 2,
});

// Do whatever you want with the html template, eg. write it to an html
// file or render it in inside an html iframe.

const fullPath = "./output.html";

fs.writeFileSync(fullPath, htmlTemplate);

Note Pass "compare" parameter to genereate an embeddable comparison map instead of a simple map. Check the Config section for more info about how to use this param.

Additionally, the HTML template listens to the following message events that you can trigger from the main page where you are rendering the template

  • onDegreeChanged: You can change the selected warming scenario from outside the tempalte code. Example, if you are rendering the template inside an iframe:

    // Simple map
    const newDegree = 3;
    const data = {
      action: "onDegreeChanged",
      degree: newDegree,
    };
    iframe.contentWindow?.postMessage(data, "*");
    // Compare map
    const newDegreeBefore = 1.5;
    const newDegreeAfter = 3;
    const data = {
      action: "onDegreeChanged",
      degreeBefore: newDegreeBefore,
      degreeAfter: newDegreeAfter,
    };
    iframe.contentWindow?.postMessage(data, "*");

getLatestMaps

Use this function to get the latest Maps. Each Map object is of type Map.

getMapObject

Get the full object of a spcific Map. eg. getMapObject(40104)

getDatasetIds

Get all the available dataset Ids. Find each map and its associated datasetId here

getDataDescriptionAtPlaceGenerator

You can generate a magic sentence that describes the data of a specific map at a specific location. Currenly, only maps whose names start with "Days above" have an associated magic sentence. Usage example:

Example:

import {
  getDataDescriptionAtPlaceGenerator,
  getMapObject,
  DataDescriptionAtPlaceFuncType,
} from "@probable-futures/probable-futures-maps";

const generator = getDataDescriptionAtPlaceGenerator();
const func: DataDescriptionAtPlaceFuncType = generator[40104];
// call the function by passing the required params:
const sentence = func({
  place: "Arizona, United States",
  valueLow: 6,
  valueMid: 32,
  valueHigh: 74,
  degree: 0.5,
  datasetId: 40104,
});

console.log(sentence);

// The result:
// Between 1970 and 2000, people in Arizona, United States could expect about 32 Days above 32°C (90°F) in an average year, 6 days in a cooler year and 74 days in a warmer year. In a 1.5°C warming scenario, people in Arizona, United States can expect about 57 Days above 32°C (90°F) in an average year, 26 days in a cooler year and 106 days in a warmer year.

Components

This library provides react components that you can use to easily and quickly integrate some of the tools and functionalities that Probable Futures provides into your own app.

Chart

Rather than calling the API and creating your own charts, we've provided a Chart component that you can easily integrate into your React app.

Props:

  • width (number, required)
  • height (number, required)
  • datasetStats (StatisticsData[], required): the stats that you receive after calling the PF API to get the climate data of a specific location (learn more about calling the api). Note that you can import that StatisticsData from @probable-futures/lib
  • datasetId (number, required)
  • warmingScenario (number, required) - supported values: 0.5 | 1 | 1.5 | 2 | 2.5 | 3
  • hideTitle (boolean, optional): show or hide the title of the chart
  • onLineClicked (Function): this event will fire whenever one of the chart lines is clicked

Example:

import { Chart } from "@probable-futures/probable-futures-maps";

const [selectedChartDegree, setSelectedChartDegree] = useState(0.5);

<Chart
  width={700}
  height={400}
  datasetStats={datasetStats}
  datasetId={40104}
  warmingScenario={selectedChartDegree}
  hideTitle
  onLineClicked={(degree) => setSelectedChartDegree(degree)}
/>;
