kandi X-RAY | leaflet.shapefile Summary
requires [shapefile-js] plus if you want it to be done in a worker, you’ll need [catiline] Options are passed to L.Geojson as is. First argument is either an array buffer of a zipped shapefile, the url to a zipped shapefile, or the url to file.shp (this assumes file.dbf exists). The importUrl parameter allows you to change where a worker loads in shp.js when using [catiline] and defaults to shp.js. To easily try this out using your own shapefile, see the demo at [leaflet.calvinmetcalf.com] where you can drag-and-drop your own shapefile and have it displayed on the map.

QUESTION
I am currently using Leaflet ShapeFile as a source of my data.
When the shape file [30MB] contains 1 big layer (Feature is big with many coordinates | A whole big polygon), the UI still working but loads very long.
When the shape file [20MB] contains multiple layers (Many Polylines, Polygons markers | Multiple Features), the UI already freezes upon load.
Is there any work around on this like load only what is visible on the map view port so performance issue will be addressed? Is this possible?

Thanks to @ghybs! I used canvas as renderer and it greatly improved performance on rendering Large Number of Features.
