geonames.js v3.0.3 NEW (see changelog)

geonames.js is a flexible library for browser and Nodejs built on top geonames.org webservices.

npm install --save geonames.js

yarn add geonames.js

You have to register (it's free) on Geonames.org in order to get the username that will be necessary for the API to work.

geonames.js depends on a native ES6 Promise implementation to be supported. If your environment doesn't support ES6 Promises, you can use a polyfill.

3. Usage:

You can fetch almost anything by taking advantage of the huge amount of information provided by geonames.org. It contains over 10 million geographical names and consists of over 9 million unique features whereof 2.8 million populated places and 5.5 million alternate names.

The list of available options in the API is in here under the webservice column.

• Import the library:

  • server usage (NodeJS)

    const { Geonames } = require('geonames.js') /* commonJS */

  • browser usage (React, Angular, Vue etc.)

    import Geonames from 'geonames.js'; /* es module */

• Usage:

  Initialize the Geoames using your settings:

  free WS

  const geonames = Geonames({
  username: 'myusername',
  lan: 'en',
  encoding: 'JSON'
  });

  commercial WS

  To use the commercial tier just define your token:

  const geonames = Geonames({
  username: 'myusername',
  token: 'mytoken',
  lan: 'en',
  encoding: 'JSON'
  });

  Since the library return promises, you can use either async/await or promise-based syntax

  plain call

  // async/await
  try{
  const continents = await geonames.search({q: 'CONT'}) //get continents
  }catch(err){
  console.error(err);
  }
  
  // promise
  geonames.search({q: 'CONT'}) //get continents
  .then(resp => {
  console.log(resp.geonames);
  })
  .catch(err => console.error(err));

  chaining calls

  // async/await
  try{
  const countries = await geonames.countryInfo({}) //get continents
  const states = await geonames.children({geonameId: countries.geonames[0].geonameId})
  const regions = await geonames.children({geonameId: states.geonames[0].geonameId});
  const cities = await geonames.children({geonameId: regions.geonames[0].geonameId});
  console.log(cities.geonames);
  }catch(err){
  console.error(err);
  }
  
  // promise
  geonames.countryInfo({}) 
  .then(countries => {
  return geonames.children({geonameId: countries.geonames[0].geonameId})
  })
  .then(states => {
  return geonames.children({geonameId: states.geonames[0].geonameId});
  })
  .then(regions => {
  return geonames.children({geonameId: regions.geonames[0].geonameId});
  })
  .then(cities => {
  console.log(cities.geonames);
  })
  .catch(err => console.log(err));
