Result and ErrorResponse pattern in typescript

README.md

Following is an implementation of the result monad, this monad can be used in place of throwing errors:

Result Type:

class Result<T>{
    private constructor(success: boolean, content: T, error: IErrorResponse | null) {
        this.success = success;
        this.error = error;
    }
    static success<T>(content: T) {
        return new Result<T>(true, content, null);
    }
    static void() {
        return new Result(true, null, null);
    }
    static failure(error: IErrorResponse)
    {
        if (!error)
        {
            throw new Error('error is required')
        }
        return new Result(false,null, error);
    }
    success: boolean;
    error: IErrorResponse | null;
}

Error Response:

interface IErrorResponse{
    code: string;
    message: string;
}

class ErrorResponse implements IErrorResponse{
    constructor(code: string, message: string) {
        this.code = code;
        this.message = message;
    }
    public code: string;
    public message: string;
}
