Evaluate Typescript from string?

Question

Is it possible to save my Typescript code in a string and evaulate it during run time? For simple example:

let code: string = `({
    Run: (data: string): string => {
        console.log(data); return Promise.resolve("SUCCESS"); }
    })`;

Then run it like this:

let runnalbe = eval(code);
runnable.Run("RUN!").then((result:string)=>{console.log(result);});

Should print:

RUN!SUCCESS

Answer 1

The official TypeScript compiler API provides a way to transpile source strings:

import * as ts from "typescript";

let code: string = `({
    Run: (data: string): string => {
        console.log(data); return Promise.resolve("SUCCESS"); }
    })`;

let result = ts.transpile(code);
let runnalbe :any = eval(result);
runnalbe.Run("RUN!").then((result:string)=>{console.log(result);});
