From b6387e8924e210c2a9a65599b7db47d0f438512a Mon Sep 17 00:00:00 2001 From: Scott Lovegrove Date: Mon, 24 Nov 2025 19:04:40 +0000 Subject: [PATCH 1/2] fix: add .js extensions to declaration file imports to resolve type re-export issue MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Fixes #407 When package.json has "type": "module", TypeScript treats .d.ts files as ESM modules, which require explicit file extensions for relative imports. Without these extensions, type re-exports from consuming packages fail with InternalResolutionError. Changes: - Add scripts/fix-dts-imports.cjs to add .js extensions to all relative imports in .d.ts files - Update build process to run fix-dts step after generating types - Add @arethetypeswrong/cli validation to integrity-checks to prevent regressions This resolves the regression introduced in v6.0.0 (PR #379) where dual module support broke type re-exports in consuming projects. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- package.json | 6 +- scripts/fix-dts-imports.cjs | 125 ++++++++++++++++++++++++++++++++++++ 2 files changed, 129 insertions(+), 2 deletions(-) create mode 100644 scripts/fix-dts-imports.cjs diff --git a/package.json b/package.json index 10af96bd..382f1d15 100644 --- a/package.json +++ b/package.json @@ -33,9 +33,11 @@ "build:cjs": "npx tsc -p tsconfig.cjs.json", "build:esm": "npx tsc -p tsconfig.esm.json", "build:fix-esm": "node scripts/fix-esm-imports.cjs", + "build:fix-dts": "node scripts/fix-dts-imports.cjs", "build:post": "echo '{\"type\":\"commonjs\"}' > dist/cjs/package.json", - "build": "npm-run-all clean build:cjs build:esm build:fix-esm build:post", - "integrity-checks": "npm-run-all clean format-check lint-check test build", + "build": "npm-run-all clean build:cjs build:esm build:fix-esm build:fix-dts build:post", + "attw": "npx @arethetypeswrong/cli --pack", + "integrity-checks": "npm-run-all clean format-check lint-check test build attw", "prepublishOnly": "npm run integrity-checks", "prepare": "npm run build" }, diff --git a/scripts/fix-dts-imports.cjs b/scripts/fix-dts-imports.cjs new file mode 100644 index 00000000..2de161d6 --- /dev/null +++ b/scripts/fix-dts-imports.cjs @@ -0,0 +1,125 @@ +#!/usr/bin/env node + +const fs = require('fs');
