📝 Walkthrough

Walkthrough

The change adds optional OpenRPC discovery for action handlers, integrates automatic Celld deployment preparation into production builds, removes the standalone Celld plugin export, updates package versioning, and revises documentation and templates.

Changes

Oxide runtime changes

Layer / File(s) Summary
OpenRPC configuration and document generation
packages/oxidejs/src/types.ts, packages/oxidejs/src/core.ts, packages/oxidejs/src/openrpc.ts, packages/oxidejs/src/index.ts, packages/oxidejs/src/context.ts, packages/oxidejs/src/openrpc.test.ts, packages/oxidejs/src/core.test.ts
Action configuration supports openrpc. The runtime builds OpenRPC 1.3.2 documents from action metadata and Effect Schema codecs. Public utilities and types are exported.
OpenRPC wrapper and development serving
packages/oxidejs/src/actions.ts, packages/oxidejs/src/actions.test.ts, packages/oxidejs/src/plugin.ts
Generated workers and Vite/Rsbuild development servers serve /__oxide/openrpc when enabled.
Automatic Celld deployment preparation
packages/oxidejs/src/wrangler.ts, packages/oxidejs/src/wrangler.test.ts, packages/oxidejs/src/plugin.ts, packages/oxidejs/src/plugins/celld.ts, packages/oxidejs/tsdown.config.ts, packages/oxidejs/package.json, packages/oxidejs/src/oxide-plugins.test.ts
Celld output uses dist/celld/entry.js, rewrites relative module paths, and runs when dist/ssr/wrangler.json exists. The standalone Celld plugin and export are removed.
Release, template, and documentation alignment
apps/website/docs/..., packages/oxidejs/README.md, packages/oxidejs/CHANGELOG.md, templates/kit/*, templates/simple/package.json, AGENTS.md
Documentation and templates describe OpenRPC, built-in Celld preparation, the new output paths, and removal of OXIDE_CELLD=1. Templates use oxidejs version 0.5.3.

Merge Risk: 🟡 Moderate · up to deeac

Celld output can be altered incorrectly, and OpenRPC discovery can expose inaccurate contracts or bypass configured middleware. These issues should be resolved before merge.

Inline comments:
In `@packages/oxidejs/README.md`:
- Line 50: Replace the invalid middleware placeholder in the oxide configuration
example with the documented empty middleware array or a concrete middleware
module list, while preserving the surrounding oxide call and actions
configuration.

In `@packages/oxidejs/src/actions.ts`:
- Line 1100: Update the generated action composition around wsUpgradeGate,
openRpcGate, middlewareGate, actionGate, and afterAction so middleware runs
before OpenRPC discovery and middleware rejections are returned for OpenRPC
requests. In attachDevMiddlewareBridge, remove the OpenRPC exclusion so the Vite
development path has the same behavior, and add regression tests covering both
generated-worker and Vite paths. Affected sites:
packages/oxidejs/src/actions.ts:1100 requires reordering the gates;
packages/oxidejs/src/plugin.ts:625-629 requires removing the OpenRPC exclusion.

In `@packages/oxidejs/src/core.ts`:
- Line 175: Update the openrpc assignment in resolveActions to disable OpenRPC
when the action transport is WebSocket, unless the implementation can emit a
correct WebSocket URL; preserve OpenRPC for non-WebSocket actions. Add or update
coverage with an object-form WebSocket action configured with openrpc: true.

In `@packages/oxidejs/src/openrpc.ts`:
- Line 86: Update the definition aggregation around target[name] so conflicting
schemas are not silently discarded: either namespace each codec’s definitions
per action or compare duplicate schemas and throw a clear error when they are
non-equivalent. Preserve reuse of identical schemas and ensure later method
references resolve to the correct definition.

In `@packages/oxidejs/src/wrangler.ts`:
- Line 382: Replace the source-wide rewrite around source.replaceAll with
token-aware module-specifier rewriting that only processes actual import or
export dependency specifiers, while skipping strings and comments. Preserve
rewriting of genuine module references and add a regression test ensuring
import-shaped text inside a string literal remains unchanged.
