fix(eve): clean up abandoned web chat streams by ctgowrie · Pull Request #2426 · vercel/eve

ctgowrie · 2026-08-22T19:56:42Z

Summary

Generated Web Chat apps rewrite active conversations to /s/<sessionId> and link new chats to /s, but the public channel/web registry item omitted both pages. This adds the existing resumable-session and sessionless new-chat pages to eve add channel/web. It also propagates an aborted HTTP request into the underlying durable event stream so browser navigation releases local Workflow World listeners instead of accumulating MaxListenersExceededWarning warnings.

Validation

Reproduced the missing routes with a newly initialized Web Chat app, confirmed both routes are included by focused scaffold coverage, and verified request cancellation reaches the underlying durable stream with the complete eve channel unit suite. The full Web Chat scaffold integration suite and registry validation also pass.

A concise changeset records the user-visible scaffold and stream-cleanup fixes.

Implementation — 2 files · +25 / -12

The registry exposes the two already-authored session pages, while the HTTP stream adapter now binds durable-stream lifetime to request lifetime.

Tests — 2 files · +28 / -2

Regression coverage verifies both generated routes and cancellation of an abandoned durable stream.

Package Details

Package: eve@0.44.1
Package directory: packages/eve
Tarball: 8.19 MB (eve-0.44.1.tgz)
Unpacked payload: 30.83 MB across 3410 published files
Installed footprint: 75.02 MB across 7124 installed files
Installed root package: 29.47 MB
Installed dependencies: 45.55 MB
Installed package instances: 35
Distinct installed package names: 34
Installed dependency edges: 53
Installed optional peer edges: 47
Runtime dependencies: 2
Peer dependencies: 5 (4 optional)

Installed footprint is measured from an isolated temporary npm install of the packed tarball.
Graph metrics read only package.json files in package directories directly beneath a node_modules boundary, including nested boundaries. Each directory is one package instance; distinct names come from those manifests. Dependency edges count each unique name in dependencies or optionalDependencies per instance; optional peer edges count peerDependencies marked optional.

Build Timing: `e2e/fixtures/agent-tools-sandbox`

This is an informational timing measurement inside eve build, from preflight through publication. Output-size measurement and profile writing are excluded.

Build mode: deployable Vercel build with sandbox template prewarm included.

Build pipeline: 2.09 s -> 2.02 s (-64.5 ms) vs main (0fe6298).
Timing is informational: shared GitHub runners are too variable for a hard timing budget.
