High-Level Overview

• Provider: The base package with no dependencies on other openbb packages.
• Core: Depends on the Provider and serves as the main infrastructural package.
• Extensions: Utility packages that leverage Core's infrastructure. Each extension is its own package.
• Providers: Utility packages extending functionality to different providers, where each provider is its own package.

Core Dependency Management

Installation

• pip: pip install -e OpenBBTerminal/openbb_platform/platform/core
• poetry: poetry install OpenBBTerminal/openbb_platform/platform/core

Using Poetry

Ensure you're in a fresh conda environment before adjusting dependencies.

• Add a Dependency: poetry add <my-dependency>
• Update Dependencies:
  • All: poetry update
  • Specific: poetry update <my-dependency>
• Remove a Dependency: poetry remove <my-dependency>

Core and Extensions

Installation

For development setup, use the provided script to install all extensions and their dependencies:

• python dev_install.py [-e|--extras]

Note

: If developing an extension, avoid installing all extensions to prevent unnecessary overhead.

Dependency Management with Poetry

• Add Platform Extension: poetry add openbb-extension-name [--dev]
• Resolve Conflicts: Adjust versions in pyproject.toml if notified by Poetry.
• Lock Dependencies: poetry lock
• Update Platform: poetry update openbb-platform
• Documentation: Maintain pyproject.toml and poetry.lock for a clear record of dependencies.
