Summary

  • The unbundled @ory/elements-react/client ESM build emitted relative imports like ./session-provider and ./frontendClient without file extensions.
  • Node ESM (and Next ESM) fails those with ERR_MODULE_NOT_FOUND.
  • After the client tsup build, rewrite relative ESM import/export specifiers to .mjs so the published client entry resolves under Node.

Test plan

  • Unit tests for rewriteEsmRelativeImports (extensionless → .mjs, no double-append, leave package specs alone)
  • Isolated Node spawn: extensionless import → ERR_MODULE_NOT_FOUND; rewritten import resolves
  • Dist assertion: every relative specifier in dist/client/*.mjs has an extension and maps to a built file
  • node -e "import('@ory/elements-react/client')" equivalent via import('./dist/client/index.mjs') succeeds after rebuild

Fixes#573

Summary by CodeRabbit

  • Bug Fixes
    • Fixed generated client modules so relative ESM imports include the required .mjs extension.
    • Improved runtime resolution of built modules in Node.js environments.
  • Tests
    • Added coverage for import rewriting, unchanged package and extension-based imports, multi-line re-exports, and built output validation.

Node ESM cannot resolve extensionless relative imports emitted by the
unbundled client build. Rewrite those specifiers to .mjs after tsup so
@ory/elements-react/client loads under Node/Next ESM.

📝 Walkthrough

Walkthrough

The client ESM build now appends .mjs to extensionless relative imports after bundling. Tests cover rewriting behavior, Node resolution, and built client output references.

Changes

ESM Import Rewrite

Layer / File(s)Summary
Rewrite helper and directory processing
packages/elements-react/src/client/rewrite-esm-relative-imports.ts
Adds helpers that append .mjs to extensionless relative specifiers and update changed .mjs files.
Client build integration
packages/elements-react/tsup.config.ts
Runs the rewrite after the client build and excludes the helper from the client entry glob.
Import and build validation
packages/elements-react/src/client/rewrite-esm-relative-imports.spec.ts
Tests source rewriting, Node ESM resolution, and relative references in built client files.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk:🔵 Low · up to a6c4b

The change makes published client ESM imports resolvable by adding .mjs extensions. The PR is mergeable with owner awareness that one dist-validation test should verify each import’s full resolved path, otherwise certain incorrect file references could go undetected.

Summary

  • The unbundled @ory/elements-react/client ESM build emitted relative imports like ./session-provider and ./frontendClient without file extensions.
  • Node ESM (and Next ESM) fails those with ERR_MODULE_NOT_FOUND.
  • After the client tsup build, rewrite relative ESM import/export specifiers to .mjs so the published client entry resolves under Node.

Test plan

  • Unit tests for rewriteEsmRelativeImports (extensionless → .mjs, no double-append, leave package specs alone)
  • Isolated Node spawn: extensionless import → ERR_MODULE_NOT_FOUND; rewritten import resolves
  • Dist assertion: every relative specifier in dist/client/*.mjs has an extension and maps to a built file
  • node -e "import('@ory/elements-react/client')" equivalent via import('./dist/client/index.mjs') succeeds after rebuild

Fixes#573

Summary by CodeRabbit

  • Bug Fixes
    • Fixed generated client modules so relative ESM imports include the required .mjs extension.
    • Improved runtime resolution of built modules in Node.js environments.
  • Tests
    • Added coverage for import rewriting, unchanged package and extension-based imports, multi-line re-exports, and built output validation.

Node ESM cannot resolve extensionless relative imports emitted by the
unbundled client build. Rewrite those specifiers to .mjs after tsup so
@ory/elements-react/client loads under Node/Next ESM.

📝 Walkthrough

Walkthrough

The client ESM build now appends .mjs to extensionless relative imports after bundling. Tests cover rewriting behavior, Node resolution, and built client output references.

Changes

ESM Import Rewrite

Layer / File(s)Summary
Rewrite helper and directory processing
packages/elements-react/src/client/rewrite-esm-relative-imports.ts
Adds helpers that append .mjs to extensionless relative specifiers and update changed .mjs files.
Client build integration
packages/elements-react/tsup.config.ts
Runs the rewrite after the client build and excludes the helper from the client entry glob.
Import and build validation
packages/elements-react/src/client/rewrite-esm-relative-imports.spec.ts
Tests source rewriting, Node ESM resolution, and relative references in built client files.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk:🔵 Low · up to a6c4b

The change makes published client ESM imports resolvable by adding .mjs extensions. The PR is mergeable with owner awareness that one dist-validation test should verify each import’s full resolved path, otherwise certain incorrect file references could go undetected.

Summary

  • The unbundled @ory/elements-react/client ESM build emitted relative imports like ./session-provider and ./frontendClient without file extensions.
  • Node ESM (and Next ESM) fails those with ERR_MODULE_NOT_FOUND.
  • After the client tsup build, rewrite relative ESM import/export specifiers to .mjs so the published client entry resolves under Node.

Test plan

  • Unit tests for rewriteEsmRelativeImports (extensionless → .mjs, no double-append, leave package specs alone)
  • Isolated Node spawn: extensionless import → ERR_MODULE_NOT_FOUND; rewritten import resolves
  • Dist assertion: every relative specifier in dist/client/*.mjs has an extension and maps to a built file
  • node -e "import('@ory/elements-react/client')" equivalent via import('./dist/client/index.mjs') succeeds after rebuild

Fixes#573

Summary by CodeRabbit

  • Bug Fixes
    • Fixed generated client modules so relative ESM imports include the required .mjs extension.
    • Improved runtime resolution of built modules in Node.js environments.
  • Tests
    • Added coverage for import rewriting, unchanged package and extension-based imports, multi-line re-exports, and built output validation.

Node ESM cannot resolve extensionless relative imports emitted by the
unbundled client build. Rewrite those specifiers to .mjs after tsup so
@ory/elements-react/client loads under Node/Next ESM.

📝 Walkthrough

Walkthrough

The client ESM build now appends .mjs to extensionless relative imports after bundling. Tests cover rewriting behavior, Node resolution, and built client output references.

Changes

ESM Import Rewrite

Layer / File(s)Summary
Rewrite helper and directory processing
packages/elements-react/src/client/rewrite-esm-relative-imports.ts
Adds helpers that append .mjs to extensionless relative specifiers and update changed .mjs files.
Client build integration
packages/elements-react/tsup.config.ts
Runs the rewrite after the client build and excludes the helper from the client entry glob.
Import and build validation
packages/elements-react/src/client/rewrite-esm-relative-imports.spec.ts
Tests source rewriting, Node ESM resolution, and relative references in built client files.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk:🔵 Low · up to a6c4b

The change makes published client ESM imports resolvable by adding .mjs extensions. The PR is mergeable with owner awareness that one dist-validation test should verify each import’s full resolved path, otherwise certain incorrect file references could go undetected.

Summary

  • The unbundled @ory/elements-react/client ESM build emitted relative imports like ./session-provider and ./frontendClient without file extensions.
  • Node ESM (and Next ESM) fails those with ERR_MODULE_NOT_FOUND.
  • After the client tsup build, rewrite relative ESM import/export specifiers to .mjs so the published client entry resolves under Node.

Test plan

  • Unit tests for rewriteEsmRelativeImports (extensionless → .mjs, no double-append, leave package specs alone)
  • Isolated Node spawn: extensionless import → ERR_MODULE_NOT_FOUND; rewritten import resolves
  • Dist assertion: every relative specifier in dist/client/*.mjs has an extension and maps to a built file
  • node -e "import('@ory/elements-react/client')" equivalent via import('./dist/client/index.mjs') succeeds after rebuild

Fixes#573

Summary by CodeRabbit

  • Bug Fixes
    • Fixed generated client modules so relative ESM imports include the required .mjs extension.
    • Improved runtime resolution of built modules in Node.js environments.
  • Tests
    • Added coverage for import rewriting, unchanged package and extension-based imports, multi-line re-exports, and built output validation.

Node ESM cannot resolve extensionless relative imports emitted by the
unbundled client build. Rewrite those specifiers to .mjs after tsup so
@ory/elements-react/client loads under Node/Next ESM.

📝 Walkthrough

Walkthrough

The client ESM build now appends .mjs to extensionless relative imports after bundling. Tests cover rewriting behavior, Node resolution, and built client output references.

Changes

ESM Import Rewrite

Layer / File(s)Summary
Rewrite helper and directory processing
packages/elements-react/src/client/rewrite-esm-relative-imports.ts
Adds helpers that append .mjs to extensionless relative specifiers and update changed .mjs files.
Client build integration
packages/elements-react/tsup.config.ts
Runs the rewrite after the client build and excludes the helper from the client entry glob.
Import and build validation
packages/elements-react/src/client/rewrite-esm-relative-imports.spec.ts
Tests source rewriting, Node ESM resolution, and relative references in built client files.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk:🔵 Low · up to a6c4b

The change makes published client ESM imports resolvable by adding .mjs extensions. The PR is mergeable with owner awareness that one dist-validation test should verify each import’s full resolved path, otherwise certain incorrect file references could go undetected.

Check the resolved pathname.

Line 128 discards directory components. For example, ./missing/frontendClient.mjs passes when dist/client/frontendClient.mjs exists. Check resolved directly so this test rejects imports whose actual target is absent.
