This moves the monorepo from the hoisted node_modules layout to the isolated pnpm default. Each package now declares the packages that it imports, instead of using what the root folder had. A full build gives the same files as with the hoisted layout.

  • Packages declare the dependencies that they imported from the hoisted root folder, with the version that the root folder had. The lockfile gets no new versions.
  • The root package.json no longer lists every workspace package as workspace:*. Each package declares the workspace packages that it imports, for example @sentry-internal/rollup-utils in the rollup configs. The root keeps three of them: @sentry-internal/node-integration-tests (its suites import it by name, also from tmp folders with their own package.json), @sentry/eslint-plugin-sdk (oxlint plugin) and @sentry/sveltekit (size-limit bundles its self-import).
  • @sentry/replay declares @sentry/conventions as a dev dependency, so its build still inlines the constant from there.
  • rollup-utils reads the sideEffects field of external packages from the nearest node_modules of the built package, not only from the root folder, and warns when it does not find an installed package there.
  • The integration test runner adds the bins of node-integration-tests to the PATH of setup commands (for example prisma generate), because the Bun and Deno packages run the shared suites with their own PATH.

packageExtensions decisions

@apm-js-collab/code-transformer-bundler-plugins imports the types of Vite, Rollup, webpack and esbuild without declaring them. pnpm-workspace.yaml declares them as optional peers, so its types use the Vite of the importing package. The real fix belongs upstream: apm-js-collab/code-transformer-bundler-plugins#49.

Peer decisions

autoInstallPeers stays false. The pnpm default (true) adds 674 package versions for peers that no package needs, for example @glimmer/component and the GraphQL tools of Gatsby.

The test runs a webpack production build. On the Node 20 CI runners it
takes 3 to 5 seconds, close to the 5 second default timeout, and some
runs time out. Locally it takes about 0.3 seconds.

Remove `nodeLinker: hoisted` and `shamefullyHoist`, so pnpm installs its
default isolated layout. Each package now resolves only the dependencies
that it or the root package.json declares.

- Packages declare the dependencies that they imported from the hoisted
  root folder, with the version that the root folder had. The lockfile
  gets no new versions.
- `tslib` is a root devDependency, because the shared tsconfig sets
  `importHelpers`.
- @sentry/replay declares `@sentry/conventions` as a devDependency, so
  its build still inlines the constant that it imports from there.
- react-router, solidstart, sveltekit and tanstackstart-react declare
  `@types/node` 18 like the root. Without it, the optional `@types/node`
  peer of Vite resolves to version 20, and the Vite plugin types of
  @sentry/server-utils do not match.
- `packageExtensions` declares the bundlers as optional peers of
  @apm-js-collab/code-transformer-bundler-plugins, because its type
  declarations import them.
- rollup-utils reads the `sideEffects` field of an external package from
  the nearest node_modules folder of the built package, not only from the
  root folder. Without this, the builds keep empty imports of packages
  that are not in the root folder, for example `import '@sentry/core'`.
- The integration test runner adds the bins of node-integration-tests
  to the `PATH` of setup commands such as `prisma generate`, because the
  Bun and Deno packages run the shared suites with their own `PATH`.
- The install-playwright action runs `npx playwright` outside the
  repository. In the repository, npm finds the playwright version in
  `node_modules/.pnpm` and then runs `node_modules/.bin/playwright`,
  which the root folder no longer has.
- The size limit of `@sentry/cloudflare (withSentry)` goes from 514 KiB
  to 515 KiB. This check bundles without minification, so the bundle
  keeps the module paths, which are about 4 KB longer under
  `node_modules/.pnpm`. The code in the bundle is the same.

The root package.json listed every workspace package as a `workspace:*`
devDependency, so that each package could import any of them from the
root node_modules folder like with Yarn. Remove these entries and
declare the workspace packages in the packages that import them, for
example `@sentry-internal/rollup-utils` in the rollup configs.

The root keeps three of them:
- `@sentry-internal/node-integration-tests`, because its suites import
  it by its own name, also from tmp folders that have their own
  package.json.
- `@sentry/eslint-plugin-sdk`, because the root oxlint config loads it
  as a JS plugin.
- `@sentry/sveltekit`, because size-limit bundles its build output,
  which imports `@sentry/sveltekit/browser-tracing-variant`.
