i want to get the value of this variable outside the function const custDetail = await registeredUser.findOne(req.params);
const dashboardReq = async (req, res, next) => {
try {
const regCust = await registeredUser.findOne({ mobile: req.params.mobile });
if (regCust == null) {
console.log("No user found");
} else {
const custDetail = await registeredUser.findOne(req.params);
}
res.status(201).json({
status: "success",
data: { regCust },
});
} catch (error) {
res.status(400).json({
status: "fail",
data: next(error),
});
}
};
Edit a simple way to pass data to another function using res.locals
router:
router.get('getDashboardRef/:mobile', userCtl.dashboardReq, userCtl.nextFunction)
dashboardReq
const dashboardReq = async (req, res, next) => {
try {
res.locals.regCust = await registeredUser.findOne({ mobile: req.params.mobile });
if (!res.locals.regCust) {
console.log("No user found");
throw new Error("No user found")
} else {
res.locals.custDetail = await registeredUser.findOne(req.params);
next()
}
} catch (error) {
res.status(400).json({
status: "fail",
data: error,
});
}
};
nextFunction
const nextFunction = (req, res) => {
//do stuff with res.locals.custDetail
res.status(201).json({
status: "success",
data: { res.locals.regCust },
});
}
try to revisit your design since the variable custDetail needs to exist inside the route itself
if this is supposed to be memoized, then maintain a map with some unique identifier from req.params with the result from registeredUser.findOne
