About

Crafter.Web is a C++ library that exposes the browser DOM api's to C++ WebAssembly.

How to use

It is highly recommended to use this with Crafter.WebBuild, but it is not strictly required if the same way of injecting the env is followed. The following instructions will be for Crafter.WebBuild.

Quickstart

create a project.json in an empty folder, open it in your preferred text editor. Create a basic project file, that describes your web project.

{
    "name": "sample-project",
    "configurations": [
        {
            "name": "debug",
            "standard": "c++26",
            "source_files": ["main"],
            "module_files": [],
            "build_dir": "./build",
            "output_dir": "./bin",
            "optimization_level": "0",
            "target": "wasm32-unknown-wasi",
            "type": "executable",
            "dependencies": [
                {
                    "path":"https://github.com/Catcrafts/Crafter.CppDOM.git",
                    "configuration":"debug"
                }
            ]
        }
    ]
}

Save and close the file, create a main.cpp

import Crafter.Web;
using namespace Crafter::Web;

int main() {
    const char id[] = "body";
    const char content = "<h1>Hello from C++!</h1>";
    Crafter::CppDOM::SetInnerHTML(id, sizeof(id)-1, content.c_str(), content.size()-1);
}

Save and close, then run crafter-webbuild serve -c debug. Now you can open the browser at http://localhost:8080/ and Hello from C++! will appear in the browser.
