Read original article
The article discusses various web storage technologies, including LocalStorage, IndexedDB, Cookies, OPFS, and WASM-SQLite, highlighting their features, limitations, and use cases for modern web applications. It notes the evolution of web applications from static HTML to complex, client-side operations that require efficient data storage solutions. Cookies, introduced in 1994, are suitable for small key-value data but have limitations in size and performance. LocalStorage, established in 2009, offers a simple API for key-value pairs but is limited to 5MB and is synchronous, potentially blocking the UI. IndexedDB, introduced in 2015, supports larger structured data and asynchronous operations, making it more suitable for complex applications. OPFS allows for binary data storage in a simulated file system, while WASM-SQLite enables high-performance database operations in the browser. The article emphasizes the importance of features like JSON support, multi-tab synchronization, indexing, and WebWorker support in choosing the right storage solution for web applications. It concludes that while each technology has its strengths and weaknesses, IndexedDB and WASM-SQLite are particularly powerful for handling complex data operations efficiently.
- Various web storage technologies are compared for their features and limitations.
