Installation

pnpm add ember-data

[!NOTE] This will install the "legacy" experience. A new installer is currently being worked on for the Polaris experience and will be available soon.

Compatibility

The following table lists WarpDrive/EmberData versions alongside information about ember compatibility.

Lockstep: the latest version of ember-source at the time of release
Supported: the versions of ember-source the release officially supports
Tested: the versions of ember-source the project tested this release against
Range: the peer-dep range the release states for ember-source

The library is often compatible with a larger range than was officially supported at the time of release, and we make an effort to test against a larger range than we officially state is supported. In many cases it will be compatible for a larger range than is shown here.

Where possible, we try to maintain this larger window of support as long as possible, but if it does become necessary to break compatibility with an older, unsupported release we do not consider it a breaking change.

The table is generated from this data using the command bun sync-readme-tables.
