RxDB 8.0.0, a reactive, offline-first, multiplatform database for JavaScript released!

After the release of RxDB 8.0.0-beta.1 earlier this month, the RxDB community released RxDB 8.0.0 yesterday. The focus of this release is better defaults and improved performance with broadcast-channel for communication. RxDB is a reactive, offline-first, multiplatform database for JavaScript.

What’s new in RxDB 8.0.0?

Breaking changes

• RxDB has upgraded to pouchdb 7.0.0, its latest version
• As disableKeyCompression was not used by many users, it is now disabled by default and has been renamed as keyCompression
• RxDatabase.collection() now only takes the json-schema as schema-attribute
• In order to comply with the json-schema-standard, it is not allowed to set the required fields using required: true, instead you can use required: ['myfield']
• Setters and save() are no more allowed on non-temporary documents. To change document-data, use RxDocument.atomicUpdate(), RxDocument.atomicSet(), or RxDocument.update().
• The document methods, RxDocument.synced$ and RxDocument.resync() are removed
• middleware-hooks contain plain json as first parameter and RxDocument as second
• You can now set QueryChangeDetection by adding the boolean field queryChangeDetection: true when creating the database

Additional Improvements

• RxDocument.atomicSet()
• RxCollection.awaitPersistence()
• Option for CORS to server-plugin
• All methods of RxDocument are bound to the instance
• Added RxReplicationState.denied$, which emits when a document failed to replicate
• Added RxReplicationState.alive$, which emits true or false depending if the replication is alive - data is transmitting properly between databases

Miscellaneous changes

• Performance is improved by enabling cross-instance communication with broadcast-channel
• Upgraded to eslint 5 and babel 7
