Migrate @suspensive/react to v3#

This skill builds on react. Read ../../react/SKILL.md first for the current v3 API surface.

Applies both v1→v2 and v2→v3 breaking changes. Agents trained on pre-v3 code still generate every removed API below — treat any occurrence of wrap, AsyncBoundary, withSuspense, or Suspense.CSROnly as code to migrate, never as code to write.

Old → new API#

Behavior changes (no code removal, new semantics):

• v3: an error thrown in an ErrorBoundary fallback propagates to the parent ErrorBoundary instead of recursively re-rendering the same fallback (#1409). See error-handling.
• v3.12: Delay children accept a render prop receiving { isDelayed }.
• v2+: requires React >= 18.0 (native useSyncExternalStore).

Codemods#

# wrap builder / with* HOCs → .with() API (v2 → v3)
npx @suspensive/codemods migrate-with-api .

# remove ignored networkMode from suspense queries (only if @suspensive/react-query is used)
npx @suspensive/codemods remove-networkmode .

Common Mistakes#

CRITICAL Generating the removed wrap builder API#

Wrong:

import { wrap } from '@suspensive/react'

const Page = wrap
  .ErrorBoundary({ fallback: ({ error }) => <>{error.message}</> })
  .Suspense({ fallback: <>loading...</> })
  .on(PageComponent)

Correct:

import { ErrorBoundary, Suspense } from '@suspensive/react'

const Page = ErrorBoundary.with(
  { fallback: ({ error }) => <>{error.message}</> },
  Suspense.with({ fallback: <>loading...</> }, PageComponent)
)

wrap.ErrorBoundaryGroup().ErrorBoundary().Suspense().on() was removed in v3; each component now exposes .with(), which also lets bundlers include only the components you import. Fixed/removed in v3 but agents trained on older code still generate this pattern.

HIGH Generating removed AsyncBoundary or with* HOCs#

Wrong:

import { AsyncBoundary } from '@suspensive/react'

const Example = ({ children }) => (
  <AsyncBoundary pendingFallback={<Spinner />} rejectedFallback={ErrorUI}>
    {children}
  </AsyncBoundary>
)

Correct:

import { ErrorBoundary, Suspense } from '@suspensive/react'

const Example = ({ children }) => (
  <ErrorBoundary fallback={ErrorUI}>
    <Suspense fallback={<Spinner />}>{children}</Suspense>
  </ErrorBoundary>
)

AsyncBoundary and withSuspense/withDelay/withErrorBoundary/withErrorBoundaryGroup were removed in v2; compose ErrorBoundary + Suspense (or use .with()). Fixed/removed in v2 but agents trained on older code still generate this pattern.

HIGH Generating removed ErrorBoundaryGroup.Reset#

Wrong:

import { ErrorBoundaryGroup } from '@suspensive/react'

const Example = () => (
  <ErrorBoundaryGroup>
    <ErrorBoundaryGroup.Reset trigger={(group) => <button onClick={group.reset}>reset all</button>} />
  </ErrorBoundaryGroup>
)

Correct:

import { ErrorBoundaryGroup } from '@suspensive/react'

const Example = () => (
  <ErrorBoundaryGroup>
    <ErrorBoundaryGroup.Consumer>
      {(group) => <button onClick={group.reset}>reset all</button>}
    </ErrorBoundaryGroup.Consumer>
  </ErrorBoundaryGroup>
)

ErrorBoundaryGroup.Reset was renamed to ErrorBoundaryGroup.Consumer with a children render prop instead of trigger. Fixed/removed in v2 but agents trained on older code still generate this pattern.

MEDIUM React 17 or useSyncExternalStore shim assumptions#

Wrong:

{
  "dependencies": {
    "react": "^17.0.2",
    "@suspensive/react": "^3.21.2"
  }
}

Correct:

{
  "dependencies": {
    "react": "^18.0.0",
    "@suspensive/react": "^3.21.2"
  }
}

v2+ requires React >= 18.0 for native useSyncExternalStore (no shim is bundled); installing alongside React 17 fails peer dependency resolution.
