Cannot find name 'console'. What could be the reason for this?

Add "dom" in your lib section in compilerOptions in tsconfig.json.

Example:

{
    "compilerOptions": {
        "rootDir": "src",
        "outDir": "bin",
        "module": "commonjs",
        "noImplicitAny": false,
        "removeComments": true,
        "preserveConstEnums": true,
        "sourceMap": true,
        "target": "es5",
        "lib": [
            "es6",
            "dom"    <------- Add this "dom" here
        ],
        "types": [
            "reflect-metadata"
        ],
        "moduleResolution": "node",
        "experimentalDecorators": true,
        "emitDecoratorMetadata": true
    }
}

You will have to install the @types/node to get the node typings, You can achieve that by executing the below command,

npm install @types/node --save-dev

Hope this helps!
