by

Database Info

To get the information about a PouchDB database, the info () method is used in PouchDB.

Syntax:

db.info([callback])

Example:

  • Create a file named “InfoExample.js” within a folder name “Examples”.
  • Add the below code to the file.
    InfoExample.js

    var PouchDB = require('PouchDB');  
var db = new PouchDB('Example_Database');  
db.info(function(err, info) {  
   if (err) {  
      return console.log(err);  
   } else {  
      console.log(info);  
   }  
});
  • Open the command prompt.
  • Execute the InfoExample.js file. 
    node InfoExample.js

Remote Database Info:

At the place of the database name, pass the path to the required database in CouchDB, to get the information of a database that is located on CouchDB.

Example:

  • Create a file named “RemoteInfoExample.js” within a folder name “Examples”.
  • Add the below code to the file.RemoteInfoExample.js: 
    var PouchDB = require('PouchDB');  
var db = new PouchDB('http://localhost:5984/students');  
db.info(function(err, info) {  
   if (err) {  
      return console.log(err);  
   } else {  
      console.log(info);  
   }  
});
  • Open the command prompt.
  • Execute the RemoteInfoExample.js file. 
    node RemoteInfoExample.js

    Output:
