Using createProgram outside node environment throws unhelpful exception message

When running createProgram from inside my angular app I'm thrown the 'ts.sys is undefined' error. This error is not helpful since I'm not given the reason for it. It took me a lot of time researching and eventually a question on SO (https://stackoverflow.com/questions/52969177/typescript-createprogram-throwing-ts-sys-is-undefined) to get the answer.

A more elaborate error message would've had been of great help.

TypeScript Version: 3.1.3

Search Terms: 'ts.sys is undefined'

Code

try {
    createProgram(Utils.getFileNames(), {
        lib: ['lib.es6.d.ts']
        // target: ScriptTarget.ES5,
        // module: ModuleKind.CommonJS
    });
} catch (ex) {
    debugger;
}

Expected behavior:

An exception message explaining I should run this code from node environment or pass my own compiler.

Actual behavior:

Throws 'ts.sys is undefined'

Inizia dal percorso dell’API createProgram e riproduci la chiamata mostrata da un ambiente Angular o da un altro ambiente non-Node. Il lavoro è completato quando l’eccezione spiega che il codice deve essere eseguito in Node o ricevere un compilatore personalizzato, invece di limitarsi a segnalare che ts.sys non è definito.
