Pouchdb:javascript Synchronizing databases

Brief introduction

POUCHDB is a database that is inspired by Apache couchdb for web design and occupies less space. The goal of the POUCHDB project is to help developers build Web applications that are well-used both online and offline, where they can be stored locally when the application is off-line, and synchronize the data with COUCHDB and other compatible servers when the online status is restored.

Pouchdb is actually a JavaScript library with a size of 131KB in the compressed format. At present, it can do the basic tasks: database creation, query, copy and delete, document (set) creation, acquisition, update and delete, query database information and listen to database changes.

Main Features:

• Lightweight, only 25KB after compression
• Cross browser, support Firefox 12+,chrome 19+,opera 12+,safari 5+,internet Explorer
