i think boxPoints function implemented as named rotatedRectPoints in OpenCV.js

you can see sample usage in https://docs.opencv.org/4.x/df/def/tutorial_js_meanshift.html

        // apply camshift to get the new location
        [trackBox, trackWindow] = cv.CamShift(dst, trackWindow, termCrit);

        // Draw it on image
        let pts = cv.rotatedRectPoints(trackBox);
        cv.line(frame, pts[0], pts[1], [255, 0, 0, 255], 3);
        cv.line(frame, pts[1], pts[2], [255, 0, 0, 255], 3);
        cv.line(frame, pts[2], pts[3], [255, 0, 0, 255], 3);
        cv.line(frame, pts[3], pts[0], [255, 0, 0, 255], 3);
