nonetheless level to v4.4 of Ember Information. If you wish to make the most of the progress

Ember Information 4.5 launched enhancements to construct dimension.

Customers of solely the core of Ember Information, particularly the retailer and ember-inflector packages, might anticipate the builds of these dependencies to be 35-50% smaller. This is because of many of the legacy help for @ember-data/mannequin having now discovered its last location at residence in that bundle as an alternative of throughout the @ember-data/retailer bundle. The scale of @ember-data/retailer is decreased from ~16kb compressed to ~9.5kb compressed, doubtlessly rather less relying on what deprecations are resolved and what different packages are current. We anticipate the core to proceed to shrink as we full the ultimate phases of eradicating InternalModel, full implementations for not too long ago accepted deprecation RFCs, and introduce RecordDataV2.

been deprecated or eliminated, and a few strategies deprecated throughout v3 of Ember are
now eliminated. For the complete checklist of eliminated APIs, go to the launch notes.

    proposed in RFC 796
  • deprecating the kind property on snapshots (which might lookup the mannequin class).

  • deprecating retailer.hasRecordForId, as peekRecord is mostly extra helpful and offers the identical data (and extra).
  • deprecating retailer.recordWasInvalid, an unused inside api that ember-model-validations seems to be utilizing.
  • deprecating passing strings to the schema lookup capabilities attributesDefinitionFor and relationshipsDefinitionFor, these APIs now anticipate an object with at the very least a kind property representing the mannequin title.
  • deprecating the -json-api fallback adapter, a hidden conduct that offered an adapter if the appliance didn’t outline one.

As at all times, deprecated code might be eradicated from the construct output by specifying the compatWith arg on the emberData configuration in your app.

Personal API removals

Customers of personal retailer APIs might discover these APIs have now been deprecated or eliminated. Inside restructuring will probably be excessive the following 6 months as we polish off the removing of InternalModel and proceed to simplify codepaths which that removing permits us to do.
