Constructor​

new ErrorBoundary(props): ErrorBoundary

Defined in: packages/ui/src/components/ErrorBoundary/ErrorBoundary.tsx:21

Parameters​

ErrorBoundaryProps

Returns​

ErrorBoundary

Overrides​

Properties​

context​

context: unknown

Defined in: node_modules/.bun/@types+react@19.2.2/node_modules/@types/react/index.d.ts:946

If using React Context, re-declare this in your class to be the React.ContextType of your static contextType. Should be used with type annotation or static contextType.

Example​

static contextType = MyContext
// For TS pre-3.7:
context!: React.ContextType<typeof MyContext>
// For TS 3.7 and above:
declare context: React.ContextType<typeof MyContext>

contextType?​

static optional contextType: Context<any>

Defined in: node_modules/.bun/@types+react@19.2.2/node_modules/@types/react/index.d.ts:922

If set, this.context will be set at runtime to the current value of the given Context.

Example​

type MyContext = number
const Ctx = React.createContext<MyContext>(0)

class Foo extends React.Component {
  static contextType = Ctx
  context!: React.ContextType<typeof Ctx>
  render () {
    return <>My context's value: {this.context}</>;
  }

Methods​

componentDidCatch()​

componentDidCatch(error, errorInfo): void

Defined in: packages/ui/src/components/ErrorBoundary/ErrorBoundary.tsx:112

Catches exceptions generated in descendant components. Unhandled exceptions will cause the entire component tree to unmount.

Parameters​

error​

Error

errorInfo​

ErrorInfo

Returns​

void

Overrides​

Component.componentDidCatch

componentDidMount()​

componentDidMount(): void

Defined in: packages/ui/src/components/ErrorBoundary/ErrorBoundary.tsx:35

Called immediately after a component is mounted. Setting state here will trigger re-rendering.

Returns​

void

Overrides​

Component.componentDidMount

componentDidUpdate()?​

optional componentDidUpdate(prevProps, prevState, snapshot?): void

Defined in: node_modules/.bun/@types+react@19.2.2/node_modules/@types/react/index.d.ts:1252

Called immediately after updating occurs. Not called for the initial render.

The snapshot is only present if getSnapshotBeforeUpdate is present and returns non-null.

Parameters​

prevProps​

Readonly<P>

prevState​

Readonly<S>

snapshot?​

any

Returns​

void

Inherited from​

Component.componentDidUpdate

componentWillMount()?​

optional componentWillMount(): void

Defined in: node_modules/.bun/@types+react@19.2.2/node_modules/@types/react/index.d.ts:1268

Called immediately before mounting occurs, and before Component.render. Avoid introducing any side-effects or subscriptions in this method.

Note: the presence of NewLifecycle.getSnapshotBeforeUpdate getSnapshotBeforeUpdate or StaticLifecycle.getDerivedStateFromProps getDerivedStateFromProps prevents this from being invoked.

Returns​

void

Deprecated​

16.3, use ComponentLifecycle.componentDidMount componentDidMount or the constructor instead; will stop working in React 17

Component.componentWillMount

componentWillReceiveProps()?​

optional componentWillReceiveProps(nextProps, nextContext): void

Defined in: node_modules/.bun/@types+react@19.2.2/node_modules/@types/react/index.d.ts:1299

Called when the component may be receiving new props. React may call this even if props have not changed, so be sure to compare new and existing props if you only want to handle changes.

Calling Component.setState generally does not trigger this method.

Note: the presence of NewLifecycle.getSnapshotBeforeUpdate getSnapshotBeforeUpdate or StaticLifecycle.getDerivedStateFromProps getDerivedStateFromProps prevents this from being invoked.

Parameters​

nextProps​

Readonly<P>

nextContext​

any

Returns​

void

Deprecated​

16.3, use static StaticLifecycle.getDerivedStateFromProps getDerivedStateFromProps instead; will stop working in React 17

Component.componentWillReceiveProps

componentWillUnmount()​

componentWillUnmount(): void

Defined in: packages/ui/src/components/ErrorBoundary/ErrorBoundary.tsx:46

Called immediately before a component is destroyed. Perform any necessary cleanup in this method, such as cancelled network requests, or cleaning up any DOM elements created in componentDidMount.

Returns​

void

Overrides​

Component.componentWillUnmount

componentWillUpdate()?​

optional componentWillUpdate(nextProps, nextState, nextContext): void

Defined in: node_modules/.bun/@types+react@19.2.2/node_modules/@types/react/index.d.ts:1331

Called immediately before rendering when new props or state is received. Not called for the initial render.

Note: You cannot call Component.setState here.

Note: the presence of NewLifecycle.getSnapshotBeforeUpdate getSnapshotBeforeUpdate or StaticLifecycle.getDerivedStateFromProps getDerivedStateFromProps prevents this from being invoked.

Parameters​

nextProps​

Readonly<P>

nextState​

Readonly<S>

getSnapshotBeforeUpdate()?​

optional getSnapshotBeforeUpdate(prevProps, prevState): any

Defined in: node_modules/.bun/@types+react@19.2.2/node_modules/@types/react/index.d.ts:1246

Runs before React applies the result of Component.render render to the document, and returns an object to be given to componentDidUpdate. Useful for saving things such as scroll position before Component.render render causes changes to it.

Note: the presence of this method prevents any of the deprecated lifecycle events from running.

Parameters​

prevProps​

Readonly<P>

prevState​

Readonly<S>

Returns​

any

shouldComponentUpdate()?​

optional shouldComponentUpdate(nextProps, nextState, nextContext): boolean

Defined in: node_modules/.bun/@types+react@19.2.2/node_modules/@types/react/index.d.ts:1200

Called to determine whether the change in props and state should trigger a re-render.

Component always returns true. PureComponent implements a shallow comparison on props and state and returns true if any props or states have changed.

If false is returned, Component.render, componentWillUpdate and componentDidUpdate will not be called.

Parameters​

nextProps​

Readonly<P>

nextState​

Readonly<S>

nextContext​

any

Returns​

boolean
