demoinfocs-wasm example

This repo demonstrates how demoinfocs-golang can be used from JavaScript with WebAssembly (WASM).

Interesting files

• app/web/index.html - HTML page for the UI, calls app/web/main.js
• app/web/main.js - JS code that calls into app/main.go to parse selected files and displays results
• app/main.go - demoinfocs-golang wrapper for WASM, exposes functions called from JS
• app/Dockerfile - Dockerized Go runner that builds the WASM binary
• app/Makefile - Makefile for building and running the demo app
• app/web/wasm_exec.js - this file is included in your Go installation (e.g. /usr/share/go-1.13/misc/wasm/wasm_exec.js)

Prerequisites

To run the example you need docker, docker-compose and make.

Running the example

1. Execute make run
   This builds and starts an NGINX docker container with a webapp that can parse player stats from a CS:GO demo.

2. Go to http://localhost:8080 to see the demo app.

Running tests for development

To run tests the test-demo default.dem needs to be downloaded using Git LFS first. This can be done with git lfs pull -I '*'.

After this the you can run make for a full build including unit and end-to-end tests.
