[TypeScript] Configuring a New TypeScript Project

This lesson walks you through creating your first .tsconfig configuration file which will tell the TypeScript compiler how to treat your .ts files.

Init a config.json file:

tsc --init

tsconfig.json, will be created:

{
    "compilerOptions": {
        "module": "commonjs",
        "target": "es5",
        "noImplicitAny": false,
        "sourceMap": false
    },
    "exclude": [
        "node_modules"
    ]
}

Previously, we nee to say:

tsc app.ts

to compile file, now, we don‘t need to do that, it will find ts files and compile when you run ‘tsc‘. notice, node_modules is excluded by default.
