Setting up PouchDB in a web application involves several steps to enable local data storage, offline access, and data synchronization capabilities. Here's a basic outline of the process:
Install PouchDB :
* Install the PouchDB library via npm or yarn, or include it directly in your HTML file using a script tag.
Create a New PouchDB Instance :
* In your JavaScript code, import or include the PouchDB library.
* Use the PouchDB constructor to create a new instance of PouchDB, specifying the desired name for the database.
// Import PouchDB library
const PouchDB = require('pouchdb');
// Create a new PouchDB instance
const myDatabase = new PouchDB('my_database_name');?
Perform Operations on the Database :
* Once you've created a PouchDB instance, you can use its APIs to perform various operations such as storing, querying, and replicating data.
* For example, you can add documents to the database using the put() method, retrieve documents using the get() method, and query data using the find() method.
// Add a document to the database
myDatabase.put({
_id: 'my_document_id',
name: 'John Doe',
age: 30
}).then(response => {
console.log('Document added:', response);
}).catch(error => {
console.error('Error adding document:', error);
});
// Retrieve a document from the database
myDatabase.get('my_document_id').then(document => {
console.log('Retrieved document:', document);
}).catch(error => {
console.error('Error retrieving document:', error);
});?
