Flow is a domain specific language designed to define control flow for customizable hooks in your application, such as for request routing, event routing, and more.
This project provides you with the Flow language frontend, compiler backend, and a virtual machine.
- A deterministic, non-turing-complete domain specific language for routing and configuration
- Special purpose literal types, such as: IPv4/IPv6 address, CIDR network, regular expression.
- Extensibility through the module system
- Execution Quota, making sure your scripts terminate within a given amount of instructions.
- Configurable language features during script compilation
- ...
Use Flow if:
- speed matters
- reliability of termination of your scripts matter.
- table based configuration is not enough
Flow was initially designed to act as a highly flexible configuration language in the x0 HTTP web application server and then evolved into a routing framework that can be used in many host application.
