Offline-First with CouchDB and PouchDB: A 2025 Demo App

This blog post showcases Pouchnotes, a 250-line demo application demonstrating offline-first note-taking using CouchDB and PouchDB. Pouchnotes allows users to create and edit notes online or offline, automatically syncing with a remote CouchDB instance. The authors detail data flow within the app and between local and remote databases, highlighting the use of PouchDB's local database, bidirectional replication, and conflict resolution strategies. The post also explores efficient TypeScript integration with PouchDB, including handling multiple document types. Built with Svelte 5, Vite, and Pico.css, Pouchnotes serves as a concise, efficient example for building offline-first applications.
