Hoppscotch executes API requests and stores all collections and environments locally using IndexedDB. Test offline functionality without needing a running backend or cloud account.
A decision guide for choosing and implementing service worker caching strategies in HTML5 apps. Covers cache-first, network-first, and stale-while-revalidate patterns with a production-ready hybrid implementation, validation steps, and browser-specific limitations.
Realm Sync helps mobile apps keep offline edits consistent with a server. Learn how to configure it, test offline behavior, and check for merge conflicts.
CouchDB's _replicator endpoint and MVCC model turn bidirectional sync into a built-in feature. Learn how continuous replication works, where conflicts surface, and what trade-offs to plan for.
Start with a single encrypted Realm file per user, add Device Sync only when cross‑device sharing is needed, and enforce trust boundaries and operational checks to mitigate common failure modes.
Two offline clients edit the same CouchDB document. After replication, users see different data depending on which leaf revision CouchDB returns. Conflicts are not corruption—they are MVCC working as designed. Here is how to detect and resolve them deterministically.
Learn how to use CouchDB’s since/until flags to replicate only the changes that matter, with a concrete step‑by‑step example and notes on conflict handling and checkpoint durability.
Titanium.Database gives Titanium apps a core SQLite wrapper for offline storage. Use transactions, parameter binding and pragma user_version for safe schema moves, then verify the sandbox file.
A decision guide for engineers evaluating CRDT-based real-time collaboration: compare sequence vs. hierarchical CRDTs, understand Canva's hybrid approach with custom precedence rules, and run a concrete latency benchmark to validate sub-150 ms edit propagation.
