How to debug

if you use vscode , edit the .vscode/launch.json , like this:

{
    "version": "0.2.0",
    "configurations": [
        {
            "type": "node",
            "request": "launch",
            "name": "TS Program",
            "args": [
                "${workspaceRoot}/src/App.ts" 
            ],
            "runtimeArgs": [
                "--nolazy",
                "-r",
                "ts-node/register"
            ],
            "sourceMaps": true,
            "cwd": "${workspaceRoot}",
            "protocol": "inspector",
            "internalConsoleOptions": "neverOpen"
        }
    ]
}

Select TS Program to debug run. Try to call http://localhost:3000/ .
