How to insert Javascript's Arraybuffer to mongodb via Node.js

Question

I'm working with storing 3d models into mongodb.

In one case, I want to store all the vertex data (which is an ArrayBuffer) of a 3d model as binary data just like this:

{
  name: model_1,
  vertexBuffer: <Binary Data>
}

How can I store the arraybuffer as binary data in mongodb via node.js?

There is a Binary() function :

const bson = require('bson');

{
  name: model_1,
  vertexBuffer: new bson.Binary(<Binary Data>)
}

But you may need to convert ArrayBuffer to Buffer. Please read Convert a binary NodeJS Buffer to JavaScript ArrayBuffer
