9c7fdd7Compare…tation is enabled The `@sentry/node` bundler plugins inject the orchestrion diagnostics channels at build time. When that is on (the default), the SDK's runtime channel injection is redundant, so default `bundleSizeOptimizations.excludeChannelInjection` to `true` to tree-shake the runtime hooks out. Users can still override it explicitly, and the default is skipped when `buildTimeInstrumentation: false`. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
… plugin excludes runtime injection Build the entry twice: plain webpack (runtime channel injection bundled by default) and with `sentryWebpackPlugin` (build-time instrumentation), which defaults `excludeChannelInjection` to true and tree-shakes the runtime injection out. assert.mjs verifies the marker is present in the plain build and absent in the plugin build. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
…ng runs The dead `if (useChannelInjection)` branch is only pruned by the minifier, so `minimize: false` left the runtime injection in the bundle. Verified: with `minimize: true`, the real `sentryWebpackPlugin` excludes the runtime injection while a plain build keeps it. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
…tests Mirror node-webpack for Vite and Rollup: build the entry plain and with the respective Sentry plugin, and assert the runtime channel-injection marker is present in the plain build but tree-shaken out with the plugin (build-time instrumentation defaults `excludeChannelInjection` to true). Verified locally that both bundlers tree-shake the runtime injection. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Build the entry plain and with `sentryEsbuildPlugin`. esbuild's single-pass tree-shaking keeps the (now dead) runtime injection in the bundle unlike webpack/vite/rollup, so this app only asserts the plain build bundles the runtime injection and the plugin build succeeds; the runtime-behavior side is covered separately.

Vite defaults to a browser target that rejects the entry's top-level await; set a node target. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Stacked on #23475.
The
@sentry/nodebundler plugins (sentryRollupPlugin,sentryWebpackPlugin,sentryEsbuildPlugin,sentryVitePlugin) inject the orchestrion diagnostics channels at build time. When that is enabled — which is the default (buildTimeInstrumentation !== false) — the SDK's runtime channel injection is redundant.So the wrappers now default
bundleSizeOptimizations.excludeChannelInjectiontotrue, which sets__SENTRY_CHANNEL_INJECTION__ = false(from #23475) and tree-shakes the runtime hooks out of the build.excludeChannelInjectionalways wins, so it can be turned back on if needed.buildTimeInstrumentation: false, the default is skipped — runtime injection is then the only thing wiring up the channels.Shared via a small
withChannelInjectionExclusionDefaulthelper (bundler-plugin/common.ts) used by all four wrappers, with unit tests.🤖 Generated with Claude Code
