imccyu e4410b2764 perf(client): read each tsdown preset's own package manifest
The client tsdown presets found a package's own manifest by name: a glob of
every packages/*/*/package.json, parsed until the name matched. tsdown's
native config loader imports each package config without module cache, so
the module-level cache never hit and all 82 configs repeated the glob
(40-125 ms each) synchronously on tsdown's main thread, where it delayed
every other package build. It was 34.5% of the client pass's main thread.

- clientBundle, staticLinked and clientLibrary take the package directory
  (import.meta.dirname at every call site) and read <dir>/package.json
  once; the package name, loader id and externals come from that manifest.
- A missing, unreadable or nameless manifest throws an actionable error.
- The glob, the name search and the module-level caches are removed.

tsdown client pass 12.78 s -> 8.73 s (median of 3 interleaved runs each,
-31.7%); all 11,566 lib outputs byte-identical; all 82 configs resolve the
same externals and banners.

Package map for the application's Remote layer: typed Client-to-Host capability calls, results, and forwarded events, for users and maintainers navigating the group. package-group

api/ — Remote API layers

English | 中文

Summary

The api/ group provides the application's Remote layer: a Client environment can call the business capabilities running on the Host — manage goals, run commands, list the plugin inventory, discover file and session references — as typed method calls, receive results or streams, send uplink items on an open stream, and observe forwarded Host events. remotes decides which capabilities are exposed and how each call reaches the right session's agent; gateway carries the calls and their results between Client and Host. The stack runs over the application's shared Connection; streaming session data is deliberately outside it.

Packages

The packages below provide the Remote layer; the package READMEs own the exhaustive contracts.

Package Role ctx key
remotes/ Chooses which Host capabilities and events the Client can consume. —
gateway/ Carries typed unary calls, multiplexed streams with their Client uplinks, and forwarded Host events. ctx.typertGateway / ctx.remote
job-controller/ Streams one background job's observation record to the Client. ctx.jobController / ctx.remote.job
session-controller/ Owns Session commands, history streams, live control state, and Agent/Session identity policy. ctx.sessionController / ctx.remote.session
settings-controller/ Owns the configuration-surface reads and writes over the settings-domain seams. ctx.settingsController, ctx.credentialsController / ctx.remote.settings, ctx.remote.credentials
workspace-controller/ Owns Workspace mutations and the complete Client Workspace projection. ctx.workspaceController / ctx.remote.workspace
terminal-controller/ Session-owned interactive shells, screen recovery and browser terminal control. ctx.terminalController / ctx.remote.terminal
workspace-files/ Owns bounded workspace file access — stat, paged read, list, and the instrumented-operation changes feed — and the Client file resource provider over it. ctx.workspaceFiles / ctx.remote.workspaceFiles

Remote calls run Client → Host over the application's shared Connection; stream items flow Host → Client on the Gateway mux, and a stream's uplink items flow Client → Host on the same logical stream. API Gateway owns Remote transport, while the controller packages own Session, configuration-surface, and Workspace behavior. Feature packages register exact Connection Fetch routes for responses that do not fit Remote invocation, such as streamed downloads.


Start with the API Gateway reference to see the Remote model end to end, then the Typert subsystem page for the shared definitions and Connection for the physical carrier.

  • API Gateway reference — the current-state reference for the Typert API Gateway: programming model, generation pipeline, and runtime invocation.
  • Typert subsystem reference — the public contracts shared by protocol, Gateway, and consumer assemblies.
  • Connection — the RPC carrier, /api trust fence, and response envelopes behind every Remote call.
