Platform Implementations

Relevant source files

This page provides an overview of how React targets multiple host environments through a renderer architecture centered on the host configuration abstraction. It covers the reconciler's renderer contract, the purpose of each renderer package in the monorepo, and the structural patterns common to all implementations.

For the DOM implementation in detail, see React DOM Implementation. For the DOM event system, see React DOM Event System. For React Native renderers, see React Native Renderers. For hydration, see Hydration System. For view transitions and gesture scheduling, see View Transitions and Gesture Scheduling. For the host configuration abstraction itself, see Host Configuration Abstraction.

The Renderer Model

React separates rendering logic into two layers:

The reconciler (react-reconciler) — handles the Fiber tree, diffing, scheduling, and work loop. It is host-agnostic.
The host config — a module that the reconciler imports as ReactFiberConfig, which the build system substitutes per platform.

Each renderer package provides its own implementation of the host config contract and wires it into the reconciler. The result is a complete, standalone renderer package (e.g. react-dom, react-native-renderer, react-test-renderer).

Host Configuration Contract

The host config is the interface between the reconciler and any platform. During the build, the file packages/react-reconciler/src/ReactFiberConfig.js is forked to the appropriate platform implementation. For third-party renderers consuming the public react-reconciler npm package, the shim ReactFiberConfig.custom.js proxies every export through a $$$config argument passed at instantiation time.

Host Config Method Categories

Category	Representative Methods	Notes
Instance creation	`createInstance`, `createTextInstance`, `appendInitialChild`	Required for all renderers
Context propagation	`getRootHostContext`, `getChildHostContext`	Tracks namespace / text-parent state
Commit lifecycle	`prepareForCommit`, `resetAfterCommit`, `commitMount`, `commitUpdate`	Called around mutation phase
Mutation (optional)	`appendChild`, `insertBefore`, `removeChild`, `commitTextUpdate`	Set `supportsMutation = true`
Persistence (optional)	`cloneInstance`, `createContainerChildSet`, `replaceContainerChildren`	Set `supportsPersistence = true`
Hydration (optional)	`supportsHydration = true`	DOM-only currently
Microtasks (optional)	`scheduleMicrotask`, `supportsMicrotasks`	DOM and noop support this
Resources / Singletons	`supportsResources`, `supportsSingletons`	DOM `<head>` hoisting
View transitions	`applyViewTransitionName`, `startViewTransition`, `measureInstance`	DOM mutation renderer only
Suspend-on-commit	`maySuspendCommit`, `preloadInstance`, `startSuspendingCommit`, `waitForCommitToBeReady`	DOM and noop

Sources: packages/react-reconciler/src/forks/ReactFiberConfig.custom.js1-200

Host Config Shim for Third-Party Renderers

ReactFiberConfig.custom.js wraps each export as:
  export const createInstance = $$$config.createInstance;

The reconciler bundle for npm is wrapped in a function module.exports = function ($$$config) { ... }, so $$$config refers to the object passed by the renderer author.

Type Declarations Per Platform

Each host config file exports a set of opaque type aliases that the reconciler works with. The concrete types differ per platform.

DOM Renderer

The DOM renderer is distributed through two packages:

react-dom — public entry point, exports createRoot, hydrateRoot, and legacy render.
react-dom-bindings — implementation detail containing ReactFiberConfigDOM.js, ReactDOMComponent.js, the event system, and form element modules.

Key responsibilities of ReactFiberConfigDOM.js:

createInstance — calls document.createElement or createElementNS (for SVG/MathML) and stores the fiber back-link via precacheFiberNode.
finalizeInitialChildren — calls setInitialProperties to apply all DOM props and returns true for elements that need commitMount (e.g., autoFocus, img).
commitUpdate — calls updateProperties to diff and apply changed props, then updateFiberProps.
prepareForCommit / resetAfterCommit — save and restore selection state, disable/re-enable event emitter during mutation.
supportsMutation = true, supportsPersistence = false, supportsHydration = true.
Supports microtasks via queueMicrotask or Promise.resolve.
Supports singletons (<head>, <html>, <body> are treated specially).
Supports resources for <link>, <style>, <script> hoisting (Float).

The HostContext in the DOM renderer tracks the XML namespace (None / SVG / Math) and, in dev mode, the ancestor tag stack for validateDOMNesting.

React Native Renderers

There are two React Native renderers, targeting different architectural layers:

Paper Renderer (Legacy)

File: packages/react-native-renderer/src/ReactFiberConfigNative.js

Uses UIManager (the legacy bridge) to create and update native views imperatively.
Instance is ReactNativeFiberHostComponent, a JS class that wraps the native tag (_nativeTag) and view config.
TextInstance is a plain number (the native tag).
Uses mutation mode (supportsMutation = true).
createInstance calls UIManager.createView(tag, viewName, rootTag, updatePayload).
finalizeInitialChildren calls UIManager.setChildren to attach initial children.
commitUpdate calls UIManager.updateView.

Sources: packages/react-native-renderer/src/ReactFiberConfigNative.js60-262

Fabric Renderer (Modern)

File: packages/react-native-renderer/src/ReactFiberConfigFabric.js

Uses nativeFabricUIManager — a JSI-based interface that operates on shadow nodes.
Instance is {node: Node, canonical: {...}}. The node is a Fabric shadow node.
Uses persistence mode (supportsPersistence = true). Nodes are immutable; updates clone them.
createInstance calls nativeFabricUIManager.createNode(tag, viewName, rootTag, updatePayload, handle).
cloneInstance calls cloneNodeWithNewProps or cloneNodeWithNewChildren depending on what changed.
completeRoot atomically commits the entire new child set to the native layer.
Event priority is resolved by querying fabricGetCurrentEventPriority from the Fabric bridge.
isPrimaryRenderer = false because Paper may coexist in the same app.

Paper vs. Fabric Comparison

Sources: packages/react-native-renderer/src/ReactFiberConfigNative.js130-200 packages/react-native-renderer/src/ReactFiberConfigFabric.js179-260

Test Renderer

File: packages/react-test-renderer/src/ReactFiberConfigTestHost.js

Renders into a plain in-memory JavaScript tree of Instance and TextInstance objects.
Instance = {type, props, isHidden, children, internalInstanceHandle, rootContainerInstance, tag: 'INSTANCE'}.
TextInstance = {text, isHidden, tag: 'TEXT'}.
getPublicInstance calls createNodeMock from the container, which allows users to return custom mock objects for refs.
Supports mutation mode only.
HostContext is always NO_CONTEXT (a frozen empty object).
Does not support hydration, microtasks, resources, or singletons.

Used for unit tests where DOM is not available or undesirable.

Sources: packages/react-test-renderer/src/ReactFiberConfigTestHost.js26-205

Noop Renderer

File: packages/react-noop-renderer/src/createReactNoop.js

The noop renderer is created by calling createReactNoop(reconciler, useMutation). It is used extensively in reconciler-level tests (react-reconciler/src/__tests__/).

Supports both mutation mode and persistence mode, selected at creation time.
Instance = {id, type, children, parent, text, prop, hidden, context}.
Includes a suspensey-thing host component type used to test commit-phase Suspense.
UPPERCASE_CONTEXT is a host context used to test context-dependent text rendering.
getPublicInstance returns the instance itself.
Exposes test utilities: flushSync, render, act, getChildrenAsJSX, toMatchRenderedOutput.

Sources: packages/react-noop-renderer/src/createReactNoop.js44-110 packages/react-noop-renderer/src/createReactNoop.js375-988

ART Renderer

File: packages/react-art/src/ReactFiberConfigART.js

Targets the ART drawing library (canvas and SVG backends).
Instance wraps ART Node and Group objects.
Uses mutation mode.
Event handling is ART-native (not delegated DOM events).
Does not support hydration, resources, singletons, or microtasks.

Sources: packages/react-art/src/ReactFiberConfigART.js1-50

Optional Capability Flags

Renderers declare which optional capabilities they support via boolean exports. The reconciler branches on these at runtime.

Flag	DOM	Fabric	Paper	Test	Noop
`supportsMutation`	✓	—	✓	✓	configurable
`supportsPersistence`	—	✓	—	—	configurable
`supportsHydration`	✓	—	—	—	—
`supportsMicrotasks`	✓	—	—	—	✓
`supportsResources`	✓	—	—	—	—
`supportsSingletons`	✓	—	—	—	—
`isPrimaryRenderer`	`true`	`false`	`true`	`true`	`true`
`warnsIfNotActing`	`true`	`false`	—	—	`true`

For each capability set to false or absent, the reconciler imports a no-op fallback module. For example, Paper imports ReactFiberConfigWithNoHydration, ReactFiberConfigWithNoPersistence, and ReactFiberConfigWithNoMicrotasks.

Host Context Propagation

Every renderer must implement getRootHostContext and getChildHostContext. These functions form a stack that travels down the fiber tree during beginWork, giving each host instance knowledge of its rendering environment.

Renderer	Context contents	Purpose
DOM	`HostContextNamespace` (0/1/2) + dev `ancestorInfo`	Track SVG/MathML namespace; validate nesting
Fabric	`{isInAParentText: boolean}`	Detect raw text outside `<Text>`
Paper	`{isInAParentText: boolean}`	Same as Fabric
Test	`NO_CONTEXT` (empty object)	No special needs
Noop	`NO_CONTEXT` or `UPPERCASE_CONTEXT`	Test context propagation

View Transition Host Hooks

Renderers that support view transitions (currently only the DOM mutation renderer) must implement an additional set of hooks. These are called by ReactFiberCommitViewTransitions.js and ReactFiberApplyGesture.js during the commit phase.

Key view-transition hooks in ReactFiberConfigDOM.js:

applyViewTransitionName / restoreViewTransitionName / cancelViewTransitionName
measureInstance / measureClonedInstance / wasInstanceInViewport / hasInstanceChanged
startViewTransition / stopViewTransition / addViewTransitionFinishedListener
startGestureTransition / getCurrentGestureOffset
cloneRootViewTransitionContainer / removeRootViewTransitionClone

Noop renderer implements stubs that immediately invoke callbacks without any animation.
