PouchDB Database Info

The PouchDB info () method is used to get the basic information about the database.

Syntax:

Database Info() Example

The following example shows how to retrieve database information using the info() method. Let's take the database "First_Database" we have created in previous example.

//Requiring the package
var PouchDB = require('PouchDB');
//Creating the database object
var db = new PouchDB('First_Database');
//Database information
db.info(function(err, info) {
   if (err) {
      return console.log(err);
   } else {
      console.log(info);
   }
});

Save the above code in a file named "Database_Info.js" within a folder name "PouchDB_Examples". Open the command prompt and execute the JavaScript file using node:

Remote Database Info

PouchDB facilitates you to get the information of a database that is located remotely on the server i.e. CouchDB. You just have to pass the path to the required database in CouchDB instead of database name.

Remote Database Info Example

The following example will retrieve the information of a database that is saved in the CouchDB server. This code gives you information of a database named "employees".

//Requiring the package
var PouchDB = require('PouchDB');
//Creating the database object
var db = new PouchDB('http://localhost:5984/employees');
//Database information
db.info(function(err, info) {
   if (err) {
      return console.log(err);
   } else {
      console.log(info);
   }
});

Save the above code in a file named "Remote_Database_Info.js" within a folder name "PouchDB_Examples". Open the command prompt and execute the JavaScript file using node:

Output:
