This reverts:
- 28b03595b research: delete Hono backend (do not merge) (#25667)
- b24a4e897 chore(server): clean up post-Hono-deletion scar tissue (#26542)
v1.14.42 broke startup for users with plugins that depend on the
Hono wire format (most visibly opencode-gemini-auth, see #26546).
Restoring Hono as the default backend on stable channels while we
investigate the actual plugin compatibility story.
OPENCODE_EXPERIMENTAL_HTTPAPI flag and dual-backend selection come
back. Stable installs default to Hono; dev/beta default to HTTP API.
Conflict resolution: took the pre-deletion side for control-plane
schemas and the seven test files where post-deletion follow-up PRs
had also touched the conflicting lines. The HTTP API code added
since the deletion (compression, cors-vary, fence, lifecycle log,
account error mapping, etc.) is preserved as-is — those still apply
on the HTTP API path for users on dev/beta channels.
- Removed @effect/language-service from both packages/core and packages/opencode tsconfig files and dependencies
- Wrapped mergeDeep calls in config loading and LLM streaming to avoid expensive remeda conditional merge type instantiations in hot paths
- Narrowed Drizzle migrate() overload signature to avoid expensive variance checks during database initialization
These changes reduce TypeScript type-checking overhead and improve startup and runtime performance for config loading, LLM streaming, and database migrations.
Moved the cross-spawn-spawner module from packages/opencode to packages/core
to enable code sharing across the monorepo. This consolidates the process
spawning infrastructure into the core package so other packages can use
cross-platform child process spawning without duplicating the implementation.
Updated all import statements across the codebase to reference the new
location (@opencode-ai/core/effect/cross-spawn-spawner). Removed the
local copy from the opencode package along with its tests.
Moves effect logging, observability, runtime utilities, flags, installation
version info, and process utilities from opencode to core package. This
enables better code sharing across packages and establishes core as the
single source of truth for foundational utilities.
All internal imports updated to use @opencode-ai/core paths for consistency.
