Devcontainer WASM-Go

Simple devcontainer for Go development

Usage

Github Codespaces

Just click the button:

Visual Studio Code

Note this assumes that you have the VS code support for remote containers and docker installed on your machine.

git clone https://github.com/dev-wasm/dev-wasm-go
cd dev-wasm-go
code ./

Visual studio should prompt you to see if you want to relaunch the workspace in a container, you do.

Building and Running

Simple example

tinygo build -wasm-abi=generic -target=wasi -o main.wasm main.go
wasmtime main.wasm --dir .

WASM CGI web serving with lighttpd

There is a simple example of web serving via WebAssembly + CGI (WAGI) in the webserver directory. It uses the lighttpd web server and mod_cgi. See the webserver/lighttpd.conf file for more details.

tinygo build -wasm-abi=generic -target=wasi -o wagi.wasm webserver/wagi.go
lighttpd -D -f webserver/lighttpd.conf

Once the server is running, VS Code or Codespaces should prompt you to connect to the open port.

HTTP Client Example

There is a more complicated example in the http directory which shows an example of making an HTTP client call using the experimental wasi+http support in wasmtime-http.
