Hermes JS Engine

Hermes is a JavaScript engine optimized for fast start-up of React Native apps on Android. It features ahead-of-time static optimization and compact bytecode.

If you're only interested in using pre-built Hermes in a new or existing React Native app, you do not need to follow this guide or have direct access to the Hermes source. Instead, just follow these instructions to enable Hermes.

Noted that each Hermes release is aimed at a specific RN version. The rule of thumb is to always follow Hermes releases strictly. Version mismatch can result in instant crash of your apps in the worst case scenario.

If you want to know how to build and hack on Hermes directly, and/or integrate Hermes built from source into a React Native app then read on.

The instructions here very briefly cover steps to build the Hermes CLI. They assume you have typical native development tools setup for your OS, and support for cmake and Ninja. For more details of required dependencies, building Hermes with different options, etc. follow these links instead:

• Building and Running Hermes
• Using a custom Hermes build in a React Native app

To build a local debug version of the Hermes CLI tools the following steps should get you started on macOS/Linux:

mkdir hermes_workingdir
cd hermes_workingdir
git clone https://github.com/facebook/hermes.git
hermes/utils/build/configure.py
cd build
ninja

Or if you're using Windows, the following should get you going in a Git Bash shell:

mkdir hermes_workingdir
cd hermes_workingdir
git -c core.autocrlf=false clone https://github.com/facebook/hermes.git
hermes/utils/build/configure.py --build-system='Visual Studio 16 2019' --cmake-flags='-A x64' --distribute
cd build
MSBuild.exe ALL_BUILD.vcxproj /p:Configuration=Release

You will now be in a directory with the output of building Hermes into CLI tools. From here you can run a piece of JavaScript as follows:

echo "'use strict'; function hello() { print('Hello World'); } hello();" | ./bin/hermes
