[Feat] TypeScript 6.0 compatibility via gl-matrix@3.4.4

Target Use Case

react-map-gl is currently not compatible with the upcoming TypeScript 6.0 release.

In Q4 2025, TypeScript 6.0 plans to drop support for module-keyword namespaces.

TypeScript ecosystem testing identified that react-map-gl is not compatible with this change due to a transitive dependency on gl-matrix <3.4.4 that uses legacy namespaces. The dependencies have now all been fixed. So the only remaining work is to bump the versions of those dependencies.

Proposal

react-map-gl has three transitive routes to depend on the problematic gl-matrix:

• A devDependency via mapbox-gl@3.9.0
• A devDependency in modules/react-mapbox via mapbox-gl: ^3.9.0
• A devDependency in modules/react-maplibre via maplibre-gl: ^5.0.0

The following package versions have already been made compatible with TS 6.0:

• gl-matrix@3.4.4
• mapbox-gl@3.15.0
• maplibre-gl@5.7.0

Please bump the existing dependencies to use these minimum versions.

Start with package.json, modules/react-mapbox/package.json, and modules/react-maplibre/package.json, then inspect the dependency tree for the three transitive gl-matrix routes. Update the existing dependency declarations to the minimum compatible versions listed in the issue and verify that all routes resolve to TypeScript 6.0-compatible packages.
