Dirty way to generate props definitions from the object

dts.ts

		let typestr = "";
		for (const key in properties) {
			if (Object.prototype.hasOwnProperty.call(properties, key)) {
				const value = properties[key];
				typestr += key + ": ";
				let t = <string> typeof value;
				t = t === "undefined" ? "unknown" : t; 
				if(t === "object" && Array.isArray(value)) {
					let tt = <string> typeof value[0];
					tt = tt === "undefined" ? "unknown" : tt;
					tt = tt === "object" ? "unknown" : tt; 
					typestr += tt + "[];";	
				} else {
					typestr += t + ";";
				}
				typestr + '\r\n';
			}
		}
		console.log(typestr);
