☰ 🌀 Datalayer Core

Python and Typescript libraries for Datalayer

Overview

Datalayer Core is the foundational package that powers the Datalayer AI Platform. It provides a TypesScript and Python packages as a Command Line Interface (CLI) for AI engineers, data scientists, and researchers to seamlessly integrate scalable compute runtimes into their workflows.

This package serves as the base foundation used by many other Datalayer packages, containing core application classes, configuration, and unified APIs for authentication, runtime management, and code execution in cloud-based environments.

Key Features

• 🔐 Simple Authentication: Easy token-based authentication with environment variable support
• 🔒 Secrets Management: Securely handle sensitive data and credentials in your workflows
• 🐍 Python Client: Programmatic access to Datalayer platform with context managers and clean resource management
• 🌐 TypeScript/React Client: React components and services for building Jupyter-based applications
• 💻 Command Line Interface: CLI tools for account and platform operations
• 🔧 Base Classes: Core application classes and configuration inherited by other Datalayer projects
• 📓 Jupyter Integration: ServiceManager and collaboration providers for notebook experiences
• 🧭 Universal Navigation: Smart navigation hooks that auto-detect and work with React Router, Next.js, or native browser

Installation

Python Client

Install Datalayer Core using pip:

pip install datalayer-core

TypeScript/React Client

Install as an npm package:

npm install @datalayer/core

Development Installation

git clone https://github.com/datalayer/core.git
cd core

# Python development
pip install -e .[test]

# TypeScript development
npm install

Quick Start with Python

1. Authentication

Set your Datalayer token as an environment variable:

export DATALAYER_API_KEY="your-api-key"

Or pass it directly to the Client:

from datalayer_core import DatalayerClient

# Using environment variable
client = DatalayerClient()

# Or pass token directly
client = DatalayerClient(api_key="your-api-key-here")

if client.authenticate():
    print("Successfully authenticated!")

2. Runtime, Snapshots, and Evals

Runtime execution, snapshot workflows, and evals CLI are now documented and maintained in:

• agent-runtimes README
• agent-runtimes CLI docs

Use agent-runtimes for runtime workloads (RuntimeClient, @datalayer, snapshots, and evals), and use datalayer-core for account/platform operations (authentication, secrets, API keys, usage, profile).

Examples

The examples show the Datalayer Client at work:

• OpenTelemetry observability: instrument Datalayer usage with OpenTelemetry traces and metrics, with a small FastAPI service and a React UI to visualize them (make targets in examples/otel).

For agents, chats and sandboxes built on the client, see the Agent Runtimes examples.

Platform Integration

Datalayer adds AI capabilities and scalable compute runtimes to your development workflows. The platform is designed to seamlessly integrate into your existing processes and supercharge your computations with the processing power you need.

Key platform features accessible through this Client and CLI:

• Remote Runtimes: Execute code on powerful remote machines with CPU, RAM, and GPU resources
• Multiple Interfaces: Access and consume runtimes through Python Client, CLI, or other integrated tools
• Scalable Compute: Dynamically scale your computational resources based on workload requirements

Development

Building the Library

# Build TypeScript library
npm run build:lib

# Build Python package
python -m build

Setup

# Install Python dependencies
pip install -e .[test]

# Install TypeScript dependencies
npm install

Code Quality

This project maintains high code quality standards with automated linting, formatting, and type checking:

# Run all checks (format, lint, type-check)
npm run check

# Auto-fix all issues
npm run check:fix

# Individual commands
npm run lint          # ESLint with React/TypeScript rules
npm run lint:fix      # Auto-fix linting issues
npm run format        # Prettier formatting
npm run format:check  # Check formatting without changes
npm run type-check    # TypeScript compilation check

Pre-commit hooks automatically run formatting and linting on staged files via Husky and lint-staged.

Running Tests

# Python tests
pip install -e .[test]
pytest datalayer_core/tests/

# TypeScript tests
npm run test

# TypeScript type checking
npm run type-check
npm run test:watch    # Watch mode
npm run test:coverage # With coverage
