Description

This pull request refactors the core session context to group session configuration and strategy under ctx.session, and cookie stores and management under ctx.cookies. It updates the stateful and stateless session handlers to use the shared context directly, reducing wrapper types and keeping session and cookie access consistent.

Key Changes

  • Replace top-level session strategy and configuration fields with ctx.session.config and ctx.session.strategy.
  • Group cookie stores and cookie management in ctx.cookies, and update API handlers and session strategies to use them.
  • Update stateful and stateless handlers to accept their context types directly; remove the wrapper context types.
  • Rename the cookie precomputation function to getPrecomputedCookies.
  • Add a session configuration example that documents stateless JWT and database-backed strategies.

Walkthrough

The router context now groups session configuration with its strategy and represents cookie stores, precomputed configurations, and cookie management together. API handlers and stateful and stateless session implementations use the updated context fields. Session and cookie operation behavior is otherwise described as unchanged.

Changes: Session and Cookie Context Restructure

Layer / File(s) Summary
Define and initialize the shared context
packages/core/src/@types/config.ts, packages/core/src/@types/internal.ts, packages/core/src/config/*
The router context now contains structured cookie data and an InternalSessionConfig pairing configuration with strategy. Context creation and request hooks populate the new fields. Session configuration examples were added to the auth configuration documentation.
Route API operations through the context
packages/core/src/actions/*, packages/core/src/api/*, packages/core/src/session/strategy.ts, packages/core/src/shared/utils/api.ts
API and callback handlers access session operations through session.strategy and cookie definitions through cookies.store. Strategy creation, session validation, and CSRF validation use the updated context.
Update stateful session handlers
packages/core/src/session/stateful/*, packages/core/src/shared/utils/session-strategy.ts
Stateful handlers accept InternalContextForStateful and access session configuration and adapters through session.config. Cookie operations use the context cookie manager and store.
Update stateless session handlers
packages/core/src/session/stateless/*
Stateless handlers accept InternalContextForStateless and access session and cookie data through the updated context. Unsupported-operation handlers use the new context type, with their errors unchanged.

Merge Risk: Moderate · up to 46eb6

Overlapping HTTP and HTTPS requests can cause HTTPS sign-in to issue an insecure cookie and leave the user unable to retrieve the session. Make cookie selection and management request-local before merging.

Full details: Title check

Explanation

The title "refactor(core): reorganize utilities and simplify session context" matches the changeset. The raw summary shows the main change is a session context refactor. Across many files, the session context moves into a structured session field with session.strategy and session.config, and cookies move into a structured cookies.store and cookies.manager. Session-strategy functions now take InternalContextForStateful or InternalContextForStateless directly. The title names this refactor. The phrase "reorganize utilities" is broader, because some changes touch shared helpers such as shared/utils/api.ts, shared/utils/session-strategy.ts, and config/cookies.ts (renamed to getPrecomputedCookies). That detail is secondary, so the title is mostly accurate. The title is concise, follows the conventional commit style, and avoids file lists and vague terms.

Full details: Docstring Coverage

Explanation

No eligible functions found in the changed files. Skipping docstring coverage check. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 0 functions across 50 files. (18 skipped: 18 over the file limit.)

A rabbit checks the session store,
Then tucks the cookie keys in more.
The strategy finds its nested place,
The context carries each trace.
Stateful paths and stateless too,
Hop through fields now neatly grouped.
And docs show both session views anew.

Keep cookie selection request-local.

If an HTTP request overlaps an HTTPS credential sign-in, it can replace the sign-in’s cookie store. The HTTPS response can then issue an insecure, unprefixed session cookie, which a subsequent HTTPS session lookup will not recognize. Bind the cookie store and manager to each request.
