How to create this kind of animation?

Question

Canvas

Can you please tell me how to create such a background animation?
I understand that this is done through canvas , but maybe there are ready-made libs?
From the ego, what I found is particles
But if you look at the video or photo, you can see a clear difference in blur and details. Is there any library that is as close as possible to this task?
