HHVM

HHVM page | HHVM documentation | Hacklang page | General group | Dev group | Twitter

HHVM is an open-source virtual machine designed for executing programs written in Hack. HHVM uses a just-in-time (JIT) compilation approach to achieve superior performance while maintaining amazing development flexibility.

HHVM should be used together with a webserver like the built in, easy to deploy Proxygen, or a FastCGI-based webserver on top of nginx or Apache.

Installing

If you're new, try our getting started guide.

You can install a prebuilt package or compile from source.

Running

You can run standalone programs just by passing them to hhvm: hhvm example.hack.

If you want to host a website:

• Install your favorite webserver. Proxygen is built into HHVM, fast and easy to deploy.
• Install our package
• Start your webserver
• Run sudo /etc/init.d/hhvm start
• Visit your site at http://.../main.hack

Our getting started guide provides a slightly more detailed introduction as well as links to more information.

Contributing

We'd love to have your help in making HHVM better. If you're interested, please read our guide to contributing.
