`wasmer` can execute both the standard binary format (`.wasm`) and the text
format defined by the WebAssembly reference interpreter (`.wat`).
Once installed, you will be able to run any wasm module (_including Nginx!_):
Once installed, you will be able to run any WebAssembly files (_including Nginx, and Lua!_):
```sh
# Run Lua
wasmer run examples/lua.wasm
# Run Nginx
wasmer run examples/nginx/nginx.wasm -- -p examples/nginx -c nginx.conf
```
## Code Structure
Wasmer is structured into different directories:
- [`src`](./src): code related to the wasmer excutable binary itself
- [`lib`](./lib): modularized libraries that Wasmer uses under the hood
## Building & Running
To build this project you will need Rust and Cargo.

## Roadmap
Wasmer is an open project guided by strong principles, aiming to be modular, flexible and fast. It is open to the community to help set its direction.

# Wasmer Libraries
Wasmer is modularized into different libraries, separated into three main sections:
* [Runtime](#Runtime)
* [Integrations](#Integrations)
* [Backends](#Backends)
## Runtime
The core of Wasmer is the runtime.
It provides the necessary abstractions on top of the WebAssembly specification.
We separated the runtime into two main libraries:
* [runtime-core](./runtime-core/): The main implementation of the runtime
* [runtime](./runtime/): Easy-to-use wrappers on top of runtime-core
## Integrations
The integrations are separated implementations in top of our runtime, that let Wasmer run more WebAssembly files.
Wasmer intends to support different integrations:
* [emscripten](./emscripten): it let us run emscripten-generated WebAssembly files, such as lua or Nginx.
* Go ABI: _we will work on this soon! Would you like to help us? 💪_
* Blazor: _researching period, see [tracking issue](https://github.com/wasmerio/wasmer/issues/97)_
## Backends
The backends let Wasmer generate code from WebAssembly files, in a way that is abstracted from the
IR library itself.
* [clif-backend](./clif-backend/): The integration of Wasmer with Cranelift
