Upload example:

import nats
import asyncio

async def main():
    nc = await nats.connect("locahost", name="object.py")
    js = nc.jetstream()
    obs = await js.create_object_store("nats-py-object-store")

    object_name = 'my-file.mp4'
    with open(object_name) as f:
        await obs.put(object_name, f)

    await nc.close()

if __name__ == '__main__':
    asyncio.run(main())

    files = await obs.list()
    for f in files:
        print(f.name, "-", f.size)

    object_name = 'my-file.mp4'
    with open("copy-"+object_name, 'w') as f:
        await obs.get(object_name, f)
