//Creating the database object  
var db = new PouchDB('http://localhost:5984/employees');  
//Reading the contents of a document  
db.get('001', function(err, doc) {  
   if (err) {  
      return console.log(err);  
   } else {  
      console.log(doc);  
   }  
});  
  • Save the file named as "Read_Remote_Document.js" within a folder name "PouchDB_Examples". Open the command prompt and execute the JavaScript file using node:
node Read_Remote_Document.js
