QUESTION
When I include currentPosition
in the useEffect
dependency array or when I delete it, the code turns into an infinite loop. Why?
I have the same problem with map but when I place map in the dependency array it's ok.
ANSWER
Answered 2021-Mar-27 at 23:44The comment from DCTID explains the reason why including the state in the useEffect
hook creates an infinite loop.
You need to make sure that this does not happen! You have two options:
add a ignore comment and leave it as it is
create a additional redundant variable to store the current value of the variable
currentPosition
and only execute the function if the value actually changed
An implementation of the second approach:

I am trying to get the nearest marker to the user location and then get directions on button click, I have passed the markers to getDirections(markers)
but when the function google.maps.geometry.spherical.computeDistanceBetween
takes the google.maps.LatLng
object throws the error Uncaught TypeError: Cannot read property 'lat' of undefined
But the markers array and the userLocation are both OK with the data (not undefined) so I can't understand what is going on.

...ANSWER
Answered 2021-Feb-27 at 06:23Your uLocation
variable is a google.maps.LatLng
object, it doesn't have a .position
property (for that matter, the .position
property of google.maps.Marker
objects isn't documented, it would be safer to call the (documented) .getPosition()
method on the markers
)
QUESTION
I have a doubt about MongoDB, I know 'what is mongo' but I am not sure if this database is good for a requirement that I need to do. Well, here I go.
Description: I need to store some data from devices (200 devices more o less) and those devices will report every 30 seconds geolocalization data (lat, long), so it will be 576.000 objects/day (2880 request = 1 device per day)
I thought this structure for my documents inside of 'locations' collection
...ANSWER
Answered 2021-Feb-23 at 16:23Is able MongoDB database to do this?
Yes, this will be fine.
Is correctly my document structure to solve this?
No, not at all!
Never store date/time values as sting, it's a design flaw. Use always proper
Date
object. (This applies for any database).Similar statement applies for the coordinate, don't store it as string. I recommend a GeoJSON Objects, then you can also create index on it and run spatial queries. Example:
location: { type: "Point", coordinates: [ -32.955465, -60.661143 ] }
When this array will be a very big month after, What will happen?
The document size in MongoDB cannot exceed 16MiByte, it's a fixed limit. So, it does not look like a good design. Maybe store locations per day or even one document per report.
There is a better way to do this? (database, framework, etc)
Well, ask 5 people and you will get 6 answers. At least your approach is not wrong.
