README

dynamic-table-json is a small PHP library that provides a JSON-based storage for dynamic table-like data. It implements the adachsoft/dynamic-table-contract package and is intended for use cases where you want to persist rows of data in JSON files without introducing a full database engine.

Features

• File-based JSON storage for tables and rows
• Separate repositories for tables and rows (JsonTableRepository, JsonRowRepository)
• Full support for TableRepositoryInterface and RowRepositoryInterface from adachsoft/dynamic-table-contract v0.4:
  • Table CRUD: create(NewTableDto), getAll(): TableCollection, update(), delete() with DuplicateTableException
  • Row CRUD: add() with NewRowDto, getAll(), getById(), update(), delete() with RowNotFoundExceptionInterface
• Row and table JSON format with explicit structure (id, values, columns schema)
• Pluggable serializers for rows and tables
• Clear separation between storage, repositories and serializers
• Dedicated exceptions for storage, decoding, missing tables/rows and duplicates (TableNotFoundException, GenericRowNotFoundException, DuplicateTableException)

Requirements

• PHP 8.2 or higher
• adachsoft/dynamic-table-contract ^0.4 (installed automatically as a dependency)

Installation

Install the package via Composer:

composer require adachsoft/dynamic-table-json

Basic concepts

• Storage: low-level access to JSON files (JsonFileStorage and JsonFileStorageInterface).
• Repositories:
  • JsonTableRepository – full implementation of TableRepositoryInterface for persisting table schemas (columns) using TableDto / NewTableDto.
  • JsonRowRepository – implementation of RowRepositoryInterface for working with table rows (including single-row operations).
• Serializers:
  • TableSerializer converts TableDto objects to and from JSON-friendly arrays.
  • RowSerializer converts RowDto/NewRowDto objects to and from the on-disk JSON format with id and values keys.
• Exceptions: custom exceptions for decoding issues, storage problems, lookup errors and duplicates (JsonStorageException, JsonDecodingException, TableNotFoundException, GenericRowNotFoundException, DuplicateTableException).
