Geoquery

Geoquery is a geographical data serving services written in Node.js and graphQL

Intro

Geoquery serves Geographical data from static JSON files located in the geoquery/server/geo-data directory of the project. On first time of starting the server the JSON data is read into memory and subsequent request are served from the memory.

Getting Started

$ npm i geoquery

#Opens web browser to inspect request
npm run demo

Deploy as Node Server

Geoquery includes a tiny node.js server that you can deploy as a microserives. The same server is deploy here https://geoquery.herokuapp.com/

This server has a very minimal configuration the headers is set to "Access-Control-Allow-Origin","*"

Calling createServer function creates a simple node.js server.

const geoquery ,{ createServer } = require('geoquery');

/**
 * @param port Request Listening PORT number
 * @param callback Executed when PORT is succesfully binded
 **/

createServer({port:process.env.PORT, callback: ({port}) =>{

}})

Create Server has interface

interface MicroServerArgType {
  port: number
  callback : (arg:{port: number}) => void
}

The PORTS is resololved following the order:

• {port} passed as argument to createServer
• process.env.PORT if port is not provided
• 80 if port or process.env.PORT is undefined

Not using Micro server. Send GET request Request

const geoquery = require("geoquery");

const query = `{
  countryByIso :country(id:"NG", mode: "iso"){						
    name						
    states {								
      name							
    }												
  }
    
  countryByPhone :country(id:"234", mode: "phone"){
    name						
    states {								
      name							
    }												
  }

  countryByName: country(id:"angola", mode: "name"){
  name						
  states {								
    name							
  }												
}

  continents
					
  countries {					
  name						
  phone						
  states {							
    name
    cities{
      name
    }						
  }					
}
}	
`;

geoquery(query).then((result) => {
  console.log(result);
});
