What is PouchDB and why use it




PouchDB is an open-source JavaScript database inspired by Apache CouchDB that is designed to run well within the browser. PouchDB was created to help web developers build applications that work as well offline as they do online. It enables applications to store data locally while offline, then synchronize it with CouchDB and compatible servers when the application is back online, keeping the user's data in sync no matter where they next login.


What are the features and benefits of PouchDB




PouchDB has many features and benefits that make it a great choice for web development. Some of them are:


  • Cross-browser compatibility: PouchDB works in Firefox, Chrome, Opera, Safari, IE and Node.js. It uses IndexedDB or WebSQL under the hood and falls back to other storage methods where they are not supported.



  • Lightweight: PouchDB is just a script tag and 46KB (gzipped) away in the browser, or $ npm install pouchdb away in Node.



  • Easy to learn: PouchDB has a simple and intuitive API that is similar to CouchDB. You can create, read, update, delete, query, and sync documents with just a few lines of code.



  • Open source: PouchDB is developed out in the open on GitHub, where you can find the source code, documentation, issues, and contributions.
