📝 Walkthrough

Walkthrough

This PR standardizes TypeScript type declaration exposure across 30+ packages by reorganizing the types field within exports maps in package.json files. Additionally, the public-api package infrastructure is refactored with Dockerfile build optimizations, esbuild plugin-based ethers resolution, and updated Railway deployment configurations.

Changes

Cohort / File(s)	Summary
Package.json exports reorganization packages/caip/package.json, packages/chain-adapters/package.json, packages/contracts/package.json, packages/errors/package.json, packages/types/package.json, packages/unchained-client/package.json, packages/utils/package.json	Added types field within exports["."] map and removed duplicate nested types entry. Standardizes type declaration positioning across core packages.
Hdwallet packages exports reorganization packages/hdwallet-coinbase/package.json, packages/hdwallet-core/package.json, packages/hdwallet-gridplus/package.json, packages/hdwallet-keepkey-electron/package.json, packages/hdwallet-keepkey-nodehid/package.json, packages/hdwallet-keepkey-nodewebusb/package.json, packages/hdwallet-keepkey-tcp/package.json, packages/hdwallet-keepkey-webusb/package.json, packages/hdwallet-keepkey/package.json, packages/hdwallet-keplr/package.json, packages/hdwallet-ledger-webhid/package.json, packages/hdwallet-ledger-webusb/package.json, packages/hdwallet-ledger/package.json, packages/hdwallet-metamask-multichain/package.json, packages/hdwallet-native-vault/package.json, packages/hdwallet-native/package.json, packages/hdwallet-phantom/package.json, packages/hdwallet-trezor-connect/package.json, packages/hdwallet-trezor/package.json, packages/hdwallet-vultisig/package.json, packages/hdwallet-walletconnectv2/package.json	Repositioned types field within exports["."] map. Most changes move types before import and require entries for consistent export ordering.
Swapper package exports reorganization packages/swapper/package.json	Reordered types entry to appear before import and require within exports["."] map.
Public API infrastructure packages/public-api/Dockerfile	Expanded workspace package copying during build, replaced multi-workspace postbuild with single trigger, removed port exposure and health checks, and simplified production stage to use prebuilt artifacts.
Public API esbuild configuration packages/public-api/esbuild.config.mjs	Replaced alias-based ethers resolution with a new ethersCompatPlugin that conditionally rewrites ethers/lib/utils imports to ethers (excluding hdwallet packages).
Public API Docker ignore configuration packages/public-api/Dockerfile.dockerignore	Added src/ directory to ignore list.
Public API deployment configuration packages/public-api/railway.json, packages/public-api/railway.toml	Added new Railway deployment config (railway.json) with build and deploy settings; removed corresponding build and deploy sections from railway.toml.

🧹 Recent nitpick comments

packages/hdwallet-native/package.json (1)

15-22: Inconsistent types ordering in sub-exports.

The "." export correctly places "types" first, but "./nativeEvents" and "./crypto/revocable" still have "import" before "types". This is inconsistent with the standardization being applied across all packages in this PR.

♻️ Proposed fix

     "./nativeEvents": {
-      "import": "./dist/esm/nativeEvents.js",
-      "types": "./dist/esm/nativeEvents.d.ts"
+      "types": "./dist/esm/nativeEvents.d.ts",
+      "import": "./dist/esm/nativeEvents.js"
     },
     "./crypto/revocable": {
-      "import": "./dist/esm/crypto/isolation/engines/default/revocable.js",
-      "types": "./dist/esm/crypto/isolation/engines/default/revocable.d.ts"
+      "types": "./dist/esm/crypto/isolation/engines/default/revocable.d.ts",
+      "import": "./dist/esm/crypto/isolation/engines/default/revocable.js"
     }

packages/public-api/Dockerfile (1)

15-48: The workspace COPY list is complete, but consider adding a lint check to prevent future omissions.

All 33 workspace packages are correctly included in the COPY statements (lines 15-48). However, this list must be manually kept in sync whenever a new workspace package is added to the root package.json. If a package is added to the workspace but forgotten in the Dockerfile, yarn install --immutable will fail.

Consider adding a CI lint check or a prominent comment referencing the root package.json workspaces configuration to help future contributors remember to update both files when adding new packages.
