Answer 1

This Method isPointNearLine is Solve my problem.

////Code Snippet.

import * as geolib from 'geolib';
const returnObj=(lat,lon)=>{
  return {
     latitude: lat, longitude:lon
  }
}
 const IsLies =  geolib.isPointNearLine(
    returnObj(25.976424, -80.238400), ////point
    returnObj(25.97641, -80.24045), ////start
    returnObj(25.97647,-80.23818), ///end
    20 ////distance in meter
);

it will return true and false.

There is another approach is we can user @turf/boolean-point-on-line

Code Snippet

var pt = turf.point([74.276089,31.478847]); //// NearPoint

///Note [[Start Point],[NearPoint],[EndPoint]]

var line = turf.lineString([[74.277908,31.479470],[74.276089,31.478847],[74.274402,31.478452]]);
var isPointOnLine = turf.booleanPointOnLine(pt, line);

it will also return True and false if Points lies on line.
