When using the webstorm plugin to generate a typescript file dtos.ts in servicestack, all date properties are initially set as strings by default.
// @Required()
to: string;
In the servicestack .cs file, this property is set as DateTime. Any suggestions on why this discrepancy exists and what steps can be taken to convert it to Date, similar to how it is done in asp.net web api?
One unique aspect of TypeScript is that it does not have a specific "deserialization step". In TypeScript, the DTOs simply define the type that is returned in the raw JSON. Since JSON does not have a data type for dates, the date values are returned as strings. When converting these strings into JavaScript objects using either JSON.parse() or eval(), the date remains a string.
To convert the default WCF Date format used by ServiceStack.Text, you can use the following function:
function todate (s) {
return new Date(parseFloat(/Date\(([^)]+)\)/.exec(s)[1]));
};
If you are utilizing the servicestack-client npm package, you can resolve the conversion like this:
import { todate } from "servicestack-client";
var date = todate(wcfDateString);
Alternatively, if you are using ss-utils.js provided by ServiceStack:
var date = $.ss.todate(wcfDateString);
By changing the default serialization of dates in ServiceStack.Text to ISO8601 format:
JsConfig.DateHandler = DateHandler.ISO8601;
You can then parse the dates natively with:
new Date(dateString)
Similarly, configuring ServiceStack.Text to return dates in UnixTimeMs format:
JsConfig.DateHandler = DateHandler.UnixTimeMs;
Will allow you to convert them natively using:
new Date(unixTimeMs)
