pouchdb-adapter-leveldb-core

Underlying adapter code for LevelDOWN-based PouchDB adapters (such as pouchdb-adapter-leveldb). Most likely you should not use this package unless you are trying to build your own PouchDB adapter based on a *DOWN database.

Usage

npm install --save-exact pouchdb-adapter-leveldb-core

Overview

pouchdb-adapter-leveldb-core is designed in such a way that you can substitute any LevelDOWN-based implementation and therefore use PouchDB over RiakDOWN, RedisDOWN, etc.

In practice, though, only a handful of LevelDOWN-based adapters are supported by PouchDB and guaranteed to run with 100% fidelity. Furthermore, adapters like RiakDOWN, MySQLDown, RedisDOWN, etc. rarely provide the feature that fans of those databases hope to get out of them, i.e. PouchDB's magical syncing capabilities on top of their favorite database. In truth, what those adapters do is reduce the underlying database to a LevelDB-like key-value store and require PouchDB to implement its own revision-handling on top of them. In other words, they tend to be unperformant and require you to exclusively use PouchDB's API to access them.

Only certain adapters (e.g. in-memory, based on MemDOWN) are officially supported by the PouchDB project; you are free to experiment with other datastores, but be forewarned of the above caveats. To see how to build a custom LevelDOWN-based database, see the source code for pouchdb-adapter-memory, pouchdb-adapter-localstorage, or pouchdb-adapter-fruitdown.

Warning: semver-free zone!

This package is conceptually an internal API used by PouchDB or its plugins. It does not follow semantic versioning (semver), and rather its version is pegged to PouchDB's. Use exact versions when installing, e.g. with --save-exact.
