Using Hermes in your project results in reduced start-up time, decreased memory usage, and an overall smaller app size.
Meta open-sourced Hermes in 2019, and we use it on all of our apps built for Android mobile devices.
To learn more about Hermes, visit its website, which contains documentation and a more in-depth overview of how it works. The Hermes GitHub repo contains guides and examples on how to start using the engine for your own applications.
If you have any further questions about Hermes, let us know on our YouTube channel, or by tweeting at us. We always want to hear from you and hope you will find this open-source project and the new ELI5 series useful.
In a series of short videos (~1 min in length), one of our Developer Advocates on the Meta Open Source team explains a Meta open source project in a way that is easy to understand and use.
We will write an accompanying blog post (like the one you're reading right now) for each of these videos, which you can find on our YouTube channel.
