TurfJS get bbox given two Points - leaflet

Question

I'm trying to move a client side method on the backend:
The client side method is using TurfJS and Leaflet to perform some operations. The only problem is that server side (nodejs) window is not available, hence I cannot use Leaflet.
I'm looking for a way to transform this piece of code in the vanilla Turf equivalent:
const pointA = turf.point([originCoords.lng, originCoords.lat]);
const pointB = turf.destination.default(pointA, 50, 45, { units: 'kilometers' });
// here I'm using leaflet to get a BBox
const latLngBounds = L.latLngBounds(
L.latLng(pointA.geometry.coordinates[1],
pointA.geometry.coordinates[0]),
L.latLng(pointB.geometry.coordinates[1], pointB.geometry.coordinates[0]),
);
// using that BBox I then create the rectangle, again with leaflet
tile = L.rectangle(latLngBounds);
I'm still newbie with this whole GeoJSON thing, and maybe I'm missing something, can someone help me?

Here is the code that uses Turf.JS only.
var turf = require('#turf/turf');
var pointA = turf.point([-75.343, 39.984]);
var pointB = turf.destination(pointA, 50, 45, { units: 'kilometers' });
//create a bbox that extends to include all the features
var bbx = turf.bbox(turf.featureCollection([pointA, pointB]));
var pgn = turf.bboxPolygon(bbx); //convert it to Polygon feature
console.log(JSON.stringify(pgn)); //output to console
The output:
{"type":"Feature","properties":{},
"geometry":{
"type":"Polygon",
"coordinates":[[
[-75.343,39.984],
[-74.92609,39.984],
[-74.92609,40.3012],
[-75.343,40.3012],
[-75.343,39.984]]]
}
}
Edit 1
Add ability to run the code:
//var turf = require('#turf/turf');
var pointA = turf.point([-75.343, 39.984]);
var pointB = turf.destination(pointA, 50, 45, { units: 'kilometers' });
//create a bbox that extends to include all the features
var bbx = turf.bbox(turf.featureCollection([pointA, pointB]));
var pgn = turf.bboxPolygon(bbx); //convert it to Polygon feature
console.log(JSON.stringify(pgn)); //output to console
