asyncLocalStorage: AsyncLocalStorage<EvaluationContext> = ...

Methods

  • Sets the transaction context using the registered transaction context propagator. Runs the callback function, in which the transactionContext will be available by calling this#getTransactionContext.

    The TransactionContextPropagator must persist the transactionContext and make it available to callback via this#getTransactionContext.

    The precedence of merging context can be seen in the specification.

    Example:

    app.use((req: Request, res: Response, next: NextFunction) => {
    const ip = res.headers.get("X-Forwarded-For")
    OpenFeature.setTransactionContext({ targetingKey: req.user.id, ipAddress: ip }, () => {
    // The transaction context is used in any flag evaluation throughout the whole call chain of next
    next();
    });
    })

    • TArgs extends unknown[]

      The optional args passed to the callback function

    • R

      The return value of the callback

    Parameters
