Missing example how compile using tsconfig.json

[CzBuCHi]

this is what im having in mind:

var config = { // this is generated on the fly ... or JSON.parse(readFileAsText('tsConfig.json'))
    "compilerOptions": {
        "target": "es6",
        "module": "commonjs",
        "outDir": "./lib",
        "jsx": "react",
    },
    "compileOnSave": false,
    "include": ["src"],
    "exclude": ["lib"]
}

var emitResult = tsc.compileByConfig(config); // this line is what im missing ..

currently i have no idea, how to resolve all files that will be compiled...

Use ts.parseJsonConfigFileContent to parse the JSON object, then pass the result to ts.createProgram. From there you can emit the files (see createProgram example).

Closing as this feels like a good answer 👍

Can not help but notice that in the createProgram there's no examples of usage of ts.parseJsonConfigFileContent.

Here is an example of usage, in my use:

const cwd = process.cwd();
const configJSON = require(path.join(cwd, 'tsconfig.json'));

// options is ts.CompilerOptions that you can use in ts.createProgram
const { options } = ts.parseJsonConfigFileContent(configJSON, ts.sys, cwd);
