Summary by CodeRabbit

  • Bug Fixes

    • Improved request-context preservation for asynchronous actions and streaming responses in StackBlitz WebContainers.
    • Ensured overlapping requests remain isolated and context is retained during streamed data pulls.
    • Preserved request context after asynchronous work and restored it correctly when actions complete or fail.
  • Documentation

    • Added guidance on WebContainer request-context behavior and required handling.
  • Chores

    • Updated OxideJS to version 0.3.2 and aligned template dependencies.

📝 Walkthrough

Walkthrough

Oxide now preserves request context in WebContainers with fallback storage, serialized request entry, and captured-store restoration. Generated actions and RPC handling use shared context helpers. Tests cover asynchronous, streaming, overlapping, and unary action behavior.

Changes

Request context handling

Layer / File(s) Summary
Context runtime and public exports
packages/oxidejs/src/context.ts, packages/oxidejs/src/index.ts
WebContainer detection, fallback request storage, context restoration, serialized entry, and public exports were added.
Generated action context propagation
packages/oxidejs/src/actions.ts, packages/oxidejs/src/actions.test.ts
Generated unary and streaming actions now use shared request-store helpers. Tests cover asynchronous context, captured stores, serialization, generated imports, and router behavior.
RPC entry and stream context integration
packages/oxidejs/src/rpc/server.ts, packages/oxidejs/src/rpc/stream.ts
RPC processing now runs through withRequestEntry. WebContainer stream operations use serialized context-aware pulls.
WebSocket test generation setup
packages/oxidejs/src/rpc/ws.test.ts, packages/oxidejs/src/rpc/ws-crossws.test.ts
WebSocket tests use shared helpers to generate actions and rewrite runtime imports.
Package and template version updates
packages/oxidejs/package.json, templates/simple/package.json, templates/tasks/package.json, packages/oxidejs/README.md
The package and template dependency versions were updated to 0.3.2. The README documents WebContainer request-context handling.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to 43c00

This change updates package versions, but the package manifests remain inconsistent with the lockfile. Frozen installs may fail or use stale dependency resolution, so this should be corrected before merge.

- Line 3: Regenerate bun.lock to reflect the 0.3.2 version updates: update
packages/oxidejs/package.json at lines 3-3 and templates/simple/package.json at
lines 18-18 as manifest sources, and ensure the corresponding lockfile entries
for packages/oxidejs, templates/simple, and templates/tasks use 0.3.2 or ^0.3.2
instead of 0.3.1 or ^0.3.1.

In `@packages/oxidejs/src/context.ts`:
- Line 107: Update the streamed-pull flow in asyncGenToStreamInContext so the
WebContainer fallback-store scope remains active through each asynchronous pull
and its promise settlement; ensure concurrent requests cannot replace the shared
syncStore seen by getRequestStore(), either by serializing pulls or isolating
storage per request. Preserve withRequestEntry’s normal lifecycle for
non-streamed handlers.
- Line 85: Update the context callback flow around fn and syncStore so
synchronous returns and throws always restore syncStore in a finally block. Only
defer restoration when fn produces a WebContainer promise result, ensuring later
getRequestStore calls do not observe a completed request context.

Regenerate bun.lock for the oxidejs version update. Update the entries for packages/oxidejs, templates/simple, and templates/tasks from 0.3.1/^0.3.1 to match the manifests' 0.3.2/^0.3.2.
