Quasar RAT Disguised as an npm Package for Detecting Vulnerabilities in Ethereum Smart Contracts
Socket researchers uncover a malicious npm package posing as a tool for detecting vulnerabilities in Etherium smart contracts.
@turf/polygon-to-linestring
Advanced tools
Converts a Polygon to (Multi)LineString or MultiPolygon to a FeatureCollection of (Multi)LineString.
Parameters
polygon
Feature<(Polygon | MultiPolygon)> Feature to convertproperties
Object translates GeoJSON properties to Feature (optional, default {}
)Examples
var poly = turf.polygon([[[125, -30], [145, -30], [145, -20], [125, -20], [125, -30]]]);
var line = turf.polygonToLineString(poly);
//addToMap
var addToMap = [line];
Returns (FeatureCollection | Feature<(LineString | MultiLinestring)>) converted (Multi)Polygon to (Multi)LineString

Object
.@turf/voronoi
][voronoi]Takes a FeatureCollection of points, and a bounding box, and returns a FeatureCollection of Voronoi polygons. (PR https://github.com/Turfjs/turf/pull/1043 - Author @stevage)
@turf/shortest-path
][shortest-path]Returns the shortest path from start to end without colliding with any feature in obstacles (PR https://github.com/Turfjs/turf/pull/956 - Author @stebogit)
@turf/boolean-parallel
][boolean-parallel]Boolean-Parallel returns True if each segment of line1
is parallel to the correspondent segment of line2
