Libs

The Libs API exposes core libraries bundled with Epos, allowing you to use them directly without separate imports or dependency setup.
All libraries are preloaded and version-aligned with the Epos runtime, ensuring compatibility and smaller bundle sizes for your project.

epos.libs.mobx

MobX — reactive state management library used internally by Epos.
You can use it directly for fine-grained observability or custom reactions.

Example

const { observable, autorun } = epos.libs.mobx

const user = observable({ name: 'Alice' })
autorun(() => console.log(user.name))
user.name = 'Bob'

epos.libs.mobxReactLite

mobx-react-lite — lightweight React bindings for MobX. Epos uses it under the hood in epos.component, but you can also import utilities like observer or useLocalObservable.

Example

const { observer } = epos.libs.mobxReactLite

epos.libs.react

React core library used by Epos. Provides all standard React exports such as useState, useEffect, and createElement.

Example

const { useState } = epos.libs.react

epos.libs.reactDom

react-dom — DOM rendering utilities for React. Primarily used by epos.render.

Example

const { createPortal } = epos.libs.reactDom

epos.libs.reactDomClient

react-dom/client — client-side rendering entry for React 18+. Provides createRoot and related APIs.

Example

const { createRoot } = epos.libs.reactDomClient

epos.libs.reactJsxRuntime

The React JSX runtime — used internally by JSX transforms. Normally you don’t need to access it directly unless writing low-level renderers or custom compilation logic.

epos.libs.yjs

Yjs — CRDT-based real-time synchronization library. Used internally by Epos for multi-context state synchronization, but you can use it directly for your own collaborative data structures.

Example

const { Doc } = epos.libs.yjs
const doc = new Doc()

All libraries exposed under epos.libs are read-only bindings — their versions are managed by Epos to guarantee runtime compatibility.
