We discussed this in Bikeshedding, apm-js runtime hooks gets bundled in frameworks still using CJS like Next.js, even if the user was not using Pino integration at all. Attempts to tree-shake it failed as Next.js is still using CJS.

We can drop support for older versions of Pino, given that pino@9.10 already exposes a tracing channel that we use, and that the injected channel was a backup for pino<9.10

This will reduce bundle sizes and ensure frameworks incapable of esm tree-shaking don't pick it up as a dependency.

I will remove @apm-js-collab/tracing-hooks as a dep from node-core since nothing else uses it.

Pull request overview

This PR drops support for Pino versions before 9.10.0 to reduce bundle size, particularly for frameworks using CommonJS (like Next.js) that cannot effectively tree-shake unused dependencies. The change removes the @apm-js-collab/tracing-hooks dependency and associated injection loader infrastructure, relying solely on the native pino_asJson tracing channel introduced in Pino 9.10.0.

Changes:

  • Removed @apm-js-collab/tracing-hooks and @apm-js-collab/code-transformer dependencies
  • Deleted the injection loader infrastructure (injectLoader.ts and related hooks)
  • Updated Pino integration to use only the native pino_asJson tracing channel
  • Updated test dependencies to use Pino 9.10.0

Approving this since it seems like a lot of users are affected by largely increased bundle/module sizes. Some suggestions:

  • I'd re-classify this as a fix and highlight it as an important change in the changelog
  • Let's ensure projects with older Pino versions only break sliently (as in, we don't actually break builds after updating the SDK).

Fix PR lacks regression test per review rules

Low Severity

Per the review rules, a fix PR needs at least one unit, integration, or E2E test that validates the regression being fixed. This PR only bumps the pino version in tests from 9.9.4 to 9.10.0 but doesn't add a new test verifying that the bundle size reduction works or that pino integration still functions correctly with only the integratedChannel. Existing tests may pass coincidentally without actually verifying the specific change.

Fix PR lacks regression test per review rules
Low Severity
Per the review rules, a fix PR needs at least one unit, integration, or E2E test that validates the regression being fixed. This PR only bumps the pino version in tests from 9.9.4 to 9.10.0 but doesn't add a new test verifying that the bundle size reduction works or that pino integration still functions correctly with only the integratedChannel. Existing tests may pass coincidentally without actually verifying the specific change.

We discussed this in Bikeshedding, apm-js runtime hooks gets bundled in frameworks still using CJS like Next.js, even if the user was not using Pino integration at all. Attempts to tree-shake it failed as Next.js is still using CJS.
We can drop support for older versions of Pino, given that pino@9.10 already exposes a tracing channel that we use, and that the injected channel was a backup for pino<9.10
This will reduce bundle sizes and ensure frameworks incapable of esm tree-shaking don't pick it up as a dependency.
I will remove @apm-js-collab/tracing-hooks as a dep from node-core since nothing else uses it.

Pull request overview
This PR drops support for Pino versions before 9.10.0 to reduce bundle size, particularly for frameworks using CommonJS (like Next.js) that cannot effectively tree-shake unused dependencies. The change removes the @apm-js-collab/tracing-hooks dependency and associated injection loader infrastructure, relying solely on the native pino_asJson tracing channel introduced in Pino 9.10.0.
Changes:
  • Removed @apm-js-collab/tracing-hooks and @apm-js-collab/code-transformer dependencies
  • Deleted the injection loader infrastructure (injectLoader.ts and related hooks)
  • Updated Pino integration to use only the native pino_asJson tracing channel
  • Updated test dependencies to use Pino 9.10.0

Approving this since it seems like a lot of users are affected by largely increased bundle/module sizes. Some suggestions:
  • I'd re-classify this as a fix and highlight it as an important change in the changelog
  • Let's ensure projects with older Pino versions only break sliently (as in, we don't actually break builds after updating the SDK).

Pull request overview
This PR drops support for Pino versions before 9.10.0 to reduce bundle size, particularly for frameworks using CommonJS (like Next.js) that cannot effectively tree-shake unused dependencies. The change removes the @apm-js-collab/tracing-hooks dependency and associated injection loader infrastructure, relying solely on the native pino_asJson tracing channel introduced in Pino 9.10.0.
Changes:
  • Removed @apm-js-collab/tracing-hooks and @apm-js-collab/code-transformer dependencies
  • Deleted the injection loader infrastructure (injectLoader.ts and related hooks)
  • Updated Pino integration to use only the native pino_asJson tracing channel
  • Updated test dependencies to use Pino 9.10.0

Approving this since it seems like a lot of users are affected by largely increased bundle/module sizes. Some suggestions:
  • I'd re-classify this as a fix and highlight it as an important change in the changelog
  • Let's ensure projects with older Pino versions only break sliently (as in, we don't actually break builds after updating the SDK).

Fix PR lacks regression test per review rules
Low Severity
Per the review rules, a fix PR needs at least one unit, integration, or E2E test that validates the regression being fixed. This PR only bumps the pino version in tests from 9.9.4 to 9.10.0 but doesn't add a new test verifying that the bundle size reduction works or that pino integration still functions correctly with only the integratedChannel. Existing tests may pass coincidentally without actually verifying the specific change.

We discussed this in Bikeshedding, apm-js runtime hooks gets bundled in frameworks still using CJS like Next.js, even if the user was not using Pino integration at all. Attempts to tree-shake it failed as Next.js is still using CJS.
We can drop support for older versions of Pino, given that pino@9.10 already exposes a tracing channel that we use, and that the injected channel was a backup for pino<9.10
This will reduce bundle sizes and ensure frameworks incapable of esm tree-shaking don't pick it up as a dependency.
I will remove @apm-js-collab/tracing-hooks as a dep from node-core since nothing else uses it.

Fix PR lacks regression test per review rules
Low Severity
Per the review rules, a fix PR needs at least one unit, integration, or E2E test that validates the regression being fixed. This PR only bumps the pino version in tests from 9.9.4 to 9.10.0 but doesn't add a new test verifying that the bundle size reduction works or that pino integration still functions correctly with only the integratedChannel. Existing tests may pass coincidentally without actually verifying the specific change.

We discussed this in Bikeshedding, apm-js runtime hooks gets bundled in frameworks still using CJS like Next.js, even if the user was not using Pino integration at all. Attempts to tree-shake it failed as Next.js is still using CJS.
We can drop support for older versions of Pino, given that pino@9.10 already exposes a tracing channel that we use, and that the injected channel was a backup for pino<9.10
This will reduce bundle sizes and ensure frameworks incapable of esm tree-shaking don't pick it up as a dependency.
I will remove @apm-js-collab/tracing-hooks as a dep from node-core since nothing else uses it.

Pull request overview
This PR drops support for Pino versions before 9.10.0 to reduce bundle size, particularly for frameworks using CommonJS (like Next.js) that cannot effectively tree-shake unused dependencies. The change removes the @apm-js-collab/tracing-hooks dependency and associated injection loader infrastructure, relying solely on the native pino_asJson tracing channel introduced in Pino 9.10.0.
Changes:
  • Removed @apm-js-collab/tracing-hooks and @apm-js-collab/code-transformer dependencies
  • Deleted the injection loader infrastructure (injectLoader.ts and related hooks)
  • Updated Pino integration to use only the native pino_asJson tracing channel
  • Updated test dependencies to use Pino 9.10.0

Approving this since it seems like a lot of users are affected by largely increased bundle/module sizes. Some suggestions:
  • I'd re-classify this as a fix and highlight it as an important change in the changelog
  • Let's ensure projects with older Pino versions only break sliently (as in, we don't actually break builds after updating the SDK).

Pull request overview
This PR drops support for Pino versions before 9.10.0 to reduce bundle size, particularly for frameworks using CommonJS (like Next.js) that cannot effectively tree-shake unused dependencies. The change removes the @apm-js-collab/tracing-hooks dependency and associated injection loader infrastructure, relying solely on the native pino_asJson tracing channel introduced in Pino 9.10.0.
Changes:
  • Removed @apm-js-collab/tracing-hooks and @apm-js-collab/code-transformer dependencies
  • Deleted the injection loader infrastructure (injectLoader.ts and related hooks)
  • Updated Pino integration to use only the native pino_asJson tracing channel
  • Updated test dependencies to use Pino 9.10.0

Approving this since it seems like a lot of users are affected by largely increased bundle/module sizes. Some suggestions:
  • I'd re-classify this as a fix and highlight it as an important change in the changelog
  • Let's ensure projects with older Pino versions only break sliently (as in, we don't actually break builds after updating the SDK).

Fix PR lacks regression test per review rules
Low Severity
Per the review rules, a fix PR needs at least one unit, integration, or E2E test that validates the regression being fixed. This PR only bumps the pino version in tests from 9.9.4 to 9.10.0 but doesn't add a new test verifying that the bundle size reduction works or that pino integration still functions correctly with only the integratedChannel. Existing tests may pass coincidentally without actually verifying the specific change.

We discussed this in Bikeshedding, apm-js runtime hooks gets bundled in frameworks still using CJS like Next.js, even if the user was not using Pino integration at all. Attempts to tree-shake it failed as Next.js is still using CJS.
We can drop support for older versions of Pino, given that pino@9.10 already exposes a tracing channel that we use, and that the injected channel was a backup for pino<9.10
This will reduce bundle sizes and ensure frameworks incapable of esm tree-shaking don't pick it up as a dependency.
I will remove @apm-js-collab/tracing-hooks as a dep from node-core since nothing else uses it.

This PR only bumps the pino version in tests from 9.9.4 to 9.10.0 but doesn't add a new test verifying that the bundle size reduction works or that pino integration still functions correctly with only the integratedChannel. Existing tests may pass coincidentally without actually verifying the specific change.

fix(node-core): Align pino mechanism type with spec conventions (#19363)
a06443b
In #18631 we noticed that Pino logs didn't match the [mechanism
types](https://develop.sentry.dev/sdk/data-model/event-payloads/exception/#exception-mechanism)
we are expecting, this PR addresses that.
