Example wasm application

Written in golang. Routing with gin. Frontend wasm application. Websocket with gorilla.

The frontend contains a form, where a couple of parameter could be set. On case of form submission, the backend validates the data and executes a script on a remote machine. The validated data is used as the arguments of the executed script.

Docker system

docker run -p -e ASSETS_DIR=/app/assets 9090:9090 wasm-examle:latest

Docker compose

• app contains the backend and frontend application
• staging represents the staging remote machine
• production represents the production remote machine.
