Core libraries

Core libraries

Elyra is built from a small set of foundational packages. You can use the CLI on its own, or pull these libraries into your own projects to build agents, terminal apps, or AI-powered web UIs.

All packages are published to npm under the @elyracode scope and ship with TypeScript types.

coding-agent

@elyracode/coding-agent

The Elyra CLI — interactive TUI, session management, slash commands, built-in tools (read, bash, edit, write), and the SDK that wires everything together. This is what you install globally to get the elyra command.

npm install -g @elyracode/coding-agent

See Quickstart, Using Elyra, and the SDK for programmatic usage.

agent-core

@elyracode/agent-core

A general-purpose agent runtime with transport abstraction, state management, and attachment support. Used internally by the coding agent, but exposed as a standalone library so you can build your own agents on the same foundation.

Key features:

  • Pluggable transports (stdio, HTTP, in-process)
  • Immutable state with event-driven updates
  • Attachment handling (files, images, blobs)
  • Extension and tool registry
npm install @elyracode/agent-core

ai

@elyracode/ai

A unified LLM API with automatic model discovery and provider configuration. Supports 30+ providers (OpenAI, Anthropic, Gemini, Cohere, Groq, xAI, OpenRouter, and more) with a single consistent interface for chat, streaming, tools, structured output, and embeddings.

npm install @elyracode/ai

See Providers and Custom Providers.

tui

@elyracode/tui

A terminal UI library with differential rendering for efficient, flicker-free text-based applications. Powers the interactive mode of the coding agent.

Key features:

  • Component model with props, state, and effects
  • Differential rendering (only redraws changed regions)
  • Built-in primitives: Box, Text, Input, List, Spinner
  • Keyboard input handling and focus management
npm install @elyracode/tui

See TUI Components.

web-ui

@elyracode/web-ui

Reusable web UI components for AI chat interfaces, powered by @elyracode/ai. Drop-in components for chat threads, message bubbles, streaming output, tool calls, and attachments — designed to be styled with your own theme.

npm install @elyracode/web-ui
