@​cloudflare/vite-plugin@​1.51.1

Patch Changes

• #15015 a60ff4d Thanks @​nickpatt! - Cut the per-request cost of local observability capture

  Every tail event was written to the trace store as its own Durable Object call, so a request paid two or three round-trips per span. On a module-heavy app under the Vite plugin that dominated dev request latency. Rows are now buffered and written in batches, taking a request from roughly thirty calls to three.

  Work in progress still shows up as it happens: the root span is written immediately, console logs and exceptions as they arrive, and a span's completion is written on the next event once 100ms has passed. An invocation that goes completely quiet writes nothing further until it ends, since the flush is driven by tail events rather than a timer.

  The Vite plugin's own router, asset and proxy workers are also no longer captured. Their traces were noise the Observability views already hid, and skipping them cuts the spans recorded per request — a side benefit being that a trace's root is now your Worker rather than __router-worker__.

• Updated dependencies [35c87e9, b4f0c97, 8cf78c8, a60ff4d, 99eb50c, 35c87e9]:

  • wrangler@4.120.0
  • miniflare@5.20260801.1-alpha

@​cloudflare/vite-plugin@​1.51.0

Minor Changes

• #14941 266172b Thanks @​nickpatt! - Improve the Local Explorer's Observability views

  console.log messages now render the way the console would (JSON-encoded strings are unwrapped and multi-argument logs are joined), traces and events can be looked up by trace or span id from the search bar, and an event's "View trace" button jumps to the exact invocation that emitted it — even when a trace_id spans several invocations (e.g. a subrequest or self fetch).

• #14996 ebd1dfd Thanks @​nickpatt! - Surface Local Explorer API to headless agents

  When a Vite dev or preview server with the Cloudflare plugin is started in a headless AI agent environment, the plugin now prints the Local Explorer API URL and useful resource routes to stdout so agents can discover and call them programmatically.

Patch Changes

• Updated dependencies [20470fa, 9c74538, 266172b, a88d169, a88d169, daf65f2, a9e5abb]:
  • wrangler@4.119.0
  • miniflare@5.20260801.0-alpha

@​cloudflare/vite-plugin@​1.50.0

Minor Changes

• #14944 a249591 Thanks @​nickpatt! - Enable local observability capture by default in dev

  wrangler dev and the Vite plugin now capture request traces and console logs into the Local Explorer's Observability tab out of the box — previously this was opt-in behind X_LOCAL_OBSERVABILITY=true. Set X_LOCAL_OBSERVABILITY=false to opt out (for example if the extra per-worker collector/streaming-tail services cause trouble in a multi-process dev-registry setup).

@​cloudflare/vite-plugin@​1.49.1

Patch Changes

• #14586 5a56dda Thanks @​emily-shen! - Rewrite local testing paths (/cdn-cgi/*)

  Miniflare v5 moved its internal local testing endpoints to /cdn-cgi/local/* (and /__cf_local/* for endpoints that must remain reachable over tunnels) to prevent any potential collision with production routes. wrangler dev and the Vite plugin now transparently rewrite the old paths to the new ones, meaning you can continue to use the old paths without issue.
