Population IO API Javascript

Simple universal Javascript Wrapper around Population.IO API

Installation

$ yarn add api-population-io

$ npm install --save api-population-io

Usage

Import the module in your code

import populationIO from 'api-population-io';

const populationIO = require('api-population-io');

Then, use the module to perform your request to PopulationIO API

You can either use promises..

populationIO.lifeExpectancy.total({
  sex: 'male',
  country: 'United Kingdom',
  dob: '1970-01-01'
})
  .then((data) => {
    console.log('total_life_expectancy:', data.total_life_expectancy);
  })
  .catch((err) => {
    console.log(err.detail);
  });

.. or callbacks, by passing the function as the second parameter

populationIO.lifeExpectancy.total({
  sex: 'male',
  country: 'United Kingdom',
  dob: '1970-01-01'
}, (err, data) => {
  if (err) {
    console.log(err.detail);
  } else {
    console.log('total_life_expectancy:', data.total_life_expectancy);
  }
});
