I have started studying with openlayers and geoserver recently. I want to save drawn point on the map to geoserver, which path should i follow in openlayers?

I am trying to draw polygons using leaflet js and I have a geojson file that has co-ordinates of different regions in langLat [longitude,latitude] format. But leaflet polygon requires us to use the co-ordinates in latLang [latitude,longitude] format. So how do I revert the array elements considering there will be different multiple dimensions of arrays for different region?
I'm using Vue-leaflet component.
<l-polygon :lat-lngs="coordinates"></l-polygon>
I hope my question made sense. Any help would be appreciated.
I'm trying to move a geoJSON polygon (the outline of a city's administrative borders) from it's original location to another arbitrary one, maintaining its shape while respecting the Mercator projection. Much like how this site does it: https://thetruesize.com/
I've experimented with moving images around the map and those do respect the mercator projection when moved north, but this isn't ideal as the geoJSON would have to be converted to an image on the fly...
Is there an easy way to do this in mapbox without modifying the entire geoJSON to new coordinates?
Thanks!
transformTranslate from Turf.js can help you to translate GeoJSON features or geometries.
I sometimes had some problems when moving polygons across the globe with transformTranslate, so I wrote some function (repl.it) that behaves a bit differently.
I have used leaflet.js to built a non geographic map using CRS
On top of this i have used leaflet draw control to manually draw lineString and then later saving them into mysql.
From the eg image above where path1, path2, path3 are different multiPoint lineString.
I wanted to know if it's possible to
find path between point A->B, B->A, A->C, C->A respectively, as its not gonna be a single lineString but combination of more than one depending where they intersect and if the intersecting line going towards the destination.
If A->D find the shortest route.
I am new to Leaflet and I would like to find out if how to create a fully interactive fictional map. I have an image that I would like to convert to a leaflet map. This image has a number of connections and points like a graph basically.
I want to first of all convert that image to the map, be able to hover over the points, highlight them and display information about them and also to create animations at some point but not immediately with the connections. There is also a requirement to display permanent labels next to each point.
Is that at all possible in Leaflet?

Yes.
Start by reading the leaflet tutorial for non-geographical maps.
Has anyone successfully implemented, or found a plugin that allows the MapBox API to draw the shortest possible line between two points on a map while taking Earth's curves into account? Google Maps already has this, see this link:
https://developers.google.com/maps/documentation/javascript/examples/geometry-headings?hl=nl
Try to drag the markers around. I have no idea what the official term is for calculating routes this way on a mercator map, I will edit the title of this question as soon as I do.
The term is called geodesic polylines or, in a case where the plane formed by the line intersects the center of the sphere, a great circle.
