# gowasmer

![gowasmer](https://raw.githubusercontent.com/mattn/gowasmer/main/_example/screenshot.png)

When compiling Go to WebAssembly, the Go compiler assumes the

WebAssembly is going to run in a JavaScript environment. Hence a

`wasm_exec.js` file is provided by the Go compiler and must be

used. However, WebAssembly can actually run everywhere. So we need to

use some hacks to make WebAssembly modules generated by the Go

compiler runnable everywhere. And that's where `gowasmer` is useful.

`gowasmer` is a port of the `wasm_exec.js` file, for Go. It assumes

the WebAssembly runtime is

[`wasmer-go`](https://github.com/wasmerio/wasmer-go/).

Alternatively, to avoid using `gowasmer`, you can compile your Go

program to WebAssembly with [TinyGo](https://tinygo.org/) as follows:

```sh

$ tinygo build -o module.wasm -target wasi .

```

## Usage

See `_example` directory.

## Installation

$ go get github.com/mattn/gowasmer
