Goal: Showcase the parent function of a middleware function
shared = require('./RoutFuctions');
app.post('/link', shared.verifyToken, (req, res) => {
...
}
In the middleware function
exports.verifyToken = function(req, res, next) {
console.log('this function was triggered by ' + ?parentFunction? )
...
next()
}
Is there a way to replace ?parentFunction? with something more specific than __filename? OR is it possible to pass an optional parameter instead?
Resolved this issue by including a parameter that points to the previous node on the client side.
return axios
.post('/link', {
token: token,
caller: 'myParentFunction'
})
...
then within the verifyToken function, the caller variable can be accessed using req.body.caller
exports.verifyToken = function(req, res, next) {
console.log('verifyToken caller = ' + req.body.caller)
...
next()
}
