LiveStore is a powerful data layer for apps that uses a reactive SQLite database to manage and sync data instantly across devices, even offline. It replaces traditional state management tools like Redux by allowing you to query and update data reactively with real-time syncing via event-sourcing. It supports many platforms and UI frameworks, offers flexible data modeling, and handles merge conflicts automatically. This means your app can work smoothly offline, sync changes seamlessly, and stay fast and reliable. LiveStore helps you build high-performance, offline-first apps with easy debugging and evolution.

# The standard string repr for dicts is hard to read:
»> my_mapping = {'a': 23, 'b': 42, 'c': 0xc0ffee}
»> my_mapping
{'b': 42, 'c': 12648430. 'a': 23} # 😞
# The "#json" module can do a much better job:
»> import json
»> print(json.dumps(my_mapping, indent=4, sort_keys=True))
{
"a": 23,
"b": 42,
"c": 12648430
}
# Note this only works with dicts containing
# primitive types (check out the "pprint" module):
»> json.dumps({all: 'yup'})
TypeError: keys must be a string
