Hello,

raw data responses in generated TS code has changed after an update from ServiceStack 5.10 to 5.11
https://docs.servicestack.net/typescript-add-servicestack-reference#raw-data-responses

Responses of byte[] are now string instead of Uint8Array in the generated TS code.
Is this a mistake or has this been intentionally changed.

Thanks
Alex

It was changed to string to match its Base64 string response property type.

You can change it back with:

TypeScriptGenerator.TypeAliases[typeof(Byte[]).Name] = "Uint8Array";

What does your DTO look like, e.g. Are you using the byte[] as the property type or the return type?

FYI I’ve just added the ability to define different aliases for return types in this commit where a byte[] array property will be generated to use string to capture its Base64 string returned in JSON APIs whilst if the entire response is binary, e.g. returns byte[] or Stream it will be generated to use a Blob type, e.g. the C# Request DTO with a byte[] property and Return Type:

public class ReturnBytes : IReturn<byte[]>
{
    public byte[] Data { get; set; }
}

Will generate the following TypeScript DTO:

export class ReturnBytes implements IReturn<Blob>
{
    public data: string;

    public constructor(init?: Partial<ReturnBytes>) { (Object as any).assign(this, init); }
    public createResponse() { return new Blob(); }
    public getTypeName() { return 'ReturnBytes'; }
}

This change is available in the latest v5.11.1 that’s now available on MyGet.

Thanks for the quick response. In our case the byte[] was the return type. I think your last adjustment is very good and fits most scenarios. But I also love the flexibility, so we can customize it according to our needs.
