The database adapter is responsible for persisting document contents and ops.

Available adapters

MemoryDB

ShareDB ships with an in-memory, non-persistent database. This is useful for testing. It has no query support.

MemoryDB does not persist its data between app restarts, and is not suitable for use in a Production environment.

ShareDBMongo

sharedb-mongo is backed by MongoDB, with full query support.

ShareDBMingoMemory

sharedb-mingo-memory is an in-memory database that implements a subset of Mongo operations, including queries. This can be useful for testing against a MongoDB-like ShareDB instance.

ShareDBPostgres

sharedb-postgres is backed by PostgreSQL, and has no query support.

Usage

An instance of a database adapter should be provided to the Backend() constructor’s db option:

const backend = new Backend({
  db: new MemoryDB(),
})
