JavaScript HLS client using MediaSourceExtension

Like front-matter, but supports multiple sections in a document.

Machine-readable regulatory database mapping WCAG to EN 301 549 and national accessibility law across 17 jurisdictions, with enforcement-body lookups.

Provides helper functions to create GeoJSON features, like points, lines, or areas on a map.

Combines a FeatureCollection of Point, LineString, or Polygon features into MultiPoint, MultiLineString, or MultiPolygon features.

Takes a GeoJSON feature and returns points at all self-intersections.

An ini encoder/decoder for node

Converts a polygon to a line string.

mjml-section

Takes any LineString or Polygon and returns the overlapping lines between both features.

Finds points that fall within polygon(s).

Returns the shortest path from start to end without colliding with any Feature in obstacles.

Polygonizes a set of lines that represents edges in a planar graph.

Checks if two geometries have an area of overlap without one being completely contained inside the other.

Takes polygons or multipolygons and an optional mask, and returns an exterior ring polygon with holes.

Lightweight utility for input validation and data extraction in Turf.js. Ensures GeoJSON inputs are in the correct format and extracts specific components like coordinates or geometries.

Takes a Feature and a bbox and clips the feature to the bbox using lineclip.
