crude-engine 0.1.1

JSON-backed CRUD helper with schema validation and execution engine

CRUDE

CRUDE is a lightweight JSON-backed CRUD helper for small Python projects.

Install from PyPI with:

pip install crude-engine

It gives you:

• JSON file loading and saving
• dot-path key access like profile.name
• optional schema validation
• simple task execution through a safe action registry

Quick Start

from crude import Crude

store = Crude("data.json", "data_schema.json")

print(store.read())
print(store.get("name"))

store.update("age", 21)
store.save()

Demo

Run the demo script:

python examples/demo.py

The demo uses temporary copies of data.json and data_schema.json, so the checked-in sample data is not modified.

Tests

Run the unit tests (built-in unittest):

python -m unittest

Schema Format

Primitive types use string names:

{
    "name": "str",
    "age": "int"
}

Nested objects use nested dictionaries:

{
    "profile": {
        "name": "str",
        "active": "bool"
    }
}

Lists can use one schema item as a template for all entries, or multiple items for index-based validation.

Notes

• read() reloads from disk.
• read_cache() reads the in-memory state.
• update(key, value) updates the cache and saves to disk.
• save() explicitly writes the current cache to disk.
• reload() reloads the cache from disk.
