Functions

Const asyncMiddlewareWrapper

  • This function wraps middlewares to enable async calls in there. It is taken from https://github.com/tranvansang/middleware-async

    FIXME: [DATAHUB-79] Once async middlewares land in express we van remove this. If we run into errors it might be necessary to use the original repo and to contribute. FIXME: [DATAHUB-81] Create robust Typescript function signature

    Parameters

    Returns (Anonymous function)

asyncWrapper

  • asyncWrapper(callback: (req: Request, res: Response, next: NextFunction) => Promise<void>): (req: Request, res: Response, next: NextFunction) => void

  • This function can be used to wrap request handlers into an async function so we can make async/await calls to prisma. It is taken from https://zellwk.com/blog/async-await-express/ FIXME: [DATAHUB-80] Once async handlers land in express we should fix this. There are also some packages that seem more robust then my snippet here.

    Parameters

    • callback: (req: Request, res: Response, next: NextFunction) => Promise<void>
        • (req: Request, res: Response, next: NextFunction): Promise<void>

          • req: Request
          • res: Response
          • next: NextFunction

          Returns Promise<void>

        • next: NextFunction

        Returns void

createPayload
