Read Document in PouchDB

by

Read Document

To retrieve the document created in PouchDB, the db.get() method is used.

Syntax:

db.get(document, callback)

Example:

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

    var PouchDB = require('PouchDB');
var db = new PouchDB('Example_Database');
db.get('100', function(err, doc) {
if (err) {
return console.log(err);
} else {
console.log(doc);
}
});
  • Open the command prompt.
  • Execute the .js file. 
    node ReadDocument.js

    Output:

    { name: 'Tom',
salary: 45000,
experience: 3,
_id: '100',
_rev: '1-99a7a70ec2a34678845637a16d57344f' }

To read a Document from the Remote Database:

Instead of the database name, pass the path of the database in order to retrieve a document from CouchDB or remote server.

Example:

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

    var PouchDB = require('PouchDB');
var db = new PouchDB('http://localhost:5984/students');
db.get('100', function(err, doc) {
if (err) {
return console.log(err);
} else {
console.log(doc);
}
});
  • Open the command prompt.
  • Execute the .js file. 
    node ReadRemoteDocument.js

    Output:

    { _id: '100',
_rev: '3-897c876543ad71f53b345feda12e65b1',
name: 'Tom',
salary: 45000,
