browser-level

`browser-level` is a JavaScript library providing an `abstract-level` compliant database interface designed specifically for web browsers, utilizing IndexedDB as its backend. The current stable version is 3.0.0. It serves as the spiritual successor to `level-js`, offering a modern, `abstract-level`-compatible API for client-side data persistence. Releases typically align with major upgrades to its underlying `abstract-level` dependency, ensuring compatibility with the broader Level ecosystem. A key differentiator is its seamless integration with browser environments, providing first-class support for both Uint8Array and Buffer (via an optional shim) for keys and values. However, due to IndexedDB's inherent limitations, `browser-level` iterators do not offer strict snapshot guarantees across multiple `next()` or `nextv()` calls, which means concurrent writes might be visible to an ongoing iteration. This necessitates careful handling for applications requiring strict transactional isolation during iteration.
