Considering that MapLibre is an open-source fork of the Mapbox rendering library, many of the Mapbox plugins can be used in conjunction with MapLibre without any issue in JavaScript. However, since MapLibre is a TypeScript library in the same spirit, if you wish to use some of the popular Mapbox plugins in your TypeScript application you will likely run into the TypeScript compiler throwing a lot of type inference errors. This is because these plugins were developed with Mapbox solely in mind.
