serializer

Made for transferring data between brython and a python webserver.

1. An issue with JSON is it can't serialize python's datetime classes very well. YAML doesn't play well with brython.

2. I needed a way to send datetime.date and datetime.time to the client. This serializer might not be the best thing for this, but it does what is needed.

3. I also send quite a bit of data from the server that is has multiple reused strings and numbers, this was written to assist in making the transfer time smaller.

4. Any python structure, nested or not can be passed.

5. It does use json under the hood to facilitate the transferring of the data between server and client.

You can pip install ujson if you want the server to encode/decode faster.

from datetime import date
import serializer
serialized = serializer.dump(date.today())
# '{"&0": {"int": 2021}, "&1": {"int": 2}, "&2": {"int": 25}, "&3": {"tuple": ["&0", "&1", "&2"]}, "date": "&3"}'
serialized.loads(serialized)
# datetime.date(2021, 2, 25)
