## Introduction [Wasmer](https://wasmer.io/) is a Standalone JIT WebAssembly runtime, aiming to be fully compatible with Emscripten, Rust and Go. Install Wasmer with: ```sh curl https://get.wasmer.io -sSfL | sh ``` ### Usage `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 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. ```sh # checkout code git clone https://github.com/wasmerio/wasmer.git cd wasmer # install tools # make sure that `python` is accessible. cargo install --path . ``` ## Testing Thanks to [spectests](https://github.com/wasmerio/wasmer/tree/master/spectests) we can assure 100% compatibility with the WebAssembly spec test suite. Tests can be run with: ```sh make test ``` If you need to re-generate the Rust tests from the spectests you can run: ```sh make spectests ``` You can also run integration tests with: ```sh make integration-tests ``` ## 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. Below are some of the goals (written with order) of this project: - [x] It should be 100% compatible with the [WebAssembly Spectest](https://github.com/wasmerio/wasmer/tree/master/spectests) - [x] It should be fast _(partially achieved)_ - [x] Support Emscripten calls _(on the works)_ - [ ] Support Rust ABI calls - [ ] Support GO ABI calls ## Architecture If you would like to know how Wasmer works under the hood, please visit our [ARCHITECTURE](https://github.com/wasmerio/wasmer/blob/master/ARCHITECTURE.md) document. ## License MIT/Apache-2.0 [Attributions](./ATTRIBUTIONS.md).
