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/boolean-disjoint
Advanced tools
@turf/boolean-disjoint is a module from the Turf.js library that provides geospatial analysis tools. This specific module is used to determine if two geometries are disjoint, meaning they do not share any points in common.
Check if two geometries are disjoint
This feature allows you to check if two geometries (e.g., points, lines, polygons) do not share any points in common. In this example, two points are checked to see if they are disjoint.
const turf = require('@turf/turf');
const booleanDisjoint = require('@turf/boolean-disjoint');
const point1 = turf.point([2, 2]);
const point2 = turf.point([4, 4]);
const disjoint = booleanDisjoint(point1, point2);
console.log(disjoint); // true
Check if a polygon and a line are disjoint
This feature allows you to check if a polygon and a line are disjoint. In this example, a polygon and a line are checked to see if they do not share any points in common.
const turf = require('@turf/turf');
const booleanDisjoint = require('@turf/boolean-disjoint');
const polygon = turf.polygon([[
[0, 0], [0, 5], [5, 5], [5, 0], [0, 0]
]]);
const line = turf.lineString([[6, 6], [7, 7]]);
const disjoint = booleanDisjoint(polygon, line);
console.log(disjoint); // true
JSTS is a JavaScript library of spatial predicates and functions for processing geometry. It provides similar functionalities to @turf/boolean-disjoint, such as checking spatial relationships between geometries. However, JSTS is a more comprehensive library that includes a wider range of geometric operations.
Geolib is a library to provide basic geospatial operations like distance calculation, bounding boxes, and more. While it does not specifically focus on boolean disjoint operations, it offers a variety of geospatial utilities that can be used in conjunction with other libraries to achieve similar results.
Boolean-disjoint returns (TRUE) if the intersection of the two geometries is an empty set.
Parameters
feature1
(Geometry | Feature<any>) GeoJSON Feature or Geometryfeature2
(Geometry | Feature<any>) GeoJSON Feature or GeometryExamples
var point = turf.point([2, 2]);
var line = turf.lineString([[1, 1], [1, 2], [1, 3], [1, 4]]);
turf.booleanDisjoint(line, point);
//=true
Returns boolean true/false
This module is part of the Turfjs project, an open source module collection dedicated to geographic algorithms. It is maintained in the Turfjs/turf repository, where you can create PRs and issues.
Install this module individually:
$ npm install @turf/boolean-disjoint
Or install the Turf module that includes it as a function:
$ npm install @turf/turf
