We are working hard on getting Hermes supported by Realm JavaScript, and we are releasing a series of pre-releases to test our progress.

We encourage you to try out the pre-release in your development environment (don't use it in production yet). Create a new issue with your observations, including details about iOS version, other JavaScript libraries. Please use the Hermes issue template.

We appreciate your feedback, but we cannot guarantee if and when we respond to your comment.

Current state

• Version: v11.0.0-rc.1 (or v11.0.0-rc.0 if you're using a React Native version between 0.66.0 and 0.68.2)
• Both iOS and Android are supported
• Required React Native version is 0.69.0 or above this is very important, since JSI is not ABI stable and your app will simply crash if the version isn't correct. Use v11.0.0-rc.0 for older versions of React Native).
• 0 of 276 tests are failing

Installation

We are keeping the pre-releases under the tag hermes, and you can install the latest pre-release using the following command:

npm install realm@hermes
