Walkthrough

A new public export schemaPath is added to the database package's main index file, providing consumers with a string constant referencing the pathname of the schema module using the module's import metadata.

Poem

🐰 A path to the schema, now out in the light,
One simple export makes everything right,
No logic was tangled, no flows had to bend,
Just a breadcrumb to guide you 'round every bend! 🌽

⚠️ Potential issue | 🔴 Critical

🧩 Analysis chain

Use fileURLToPath for cross-platform file system path compatibility.

Using URL.pathname to extract file system paths has cross-platform issues. On Windows, pathname returns paths with a leading slash and drive letter (e.g., /C:/Users/...), which is not a valid Windows file system path. Node.js provides fileURLToPath from the url module specifically for converting file URLs to proper file system paths across platforms.

Apply this diff to fix the cross-platform compatibility:

+import { fileURLToPath } from "url";
+
 import { sql } from "drizzle-orm";
 import { drizzle, type PostgresJsDatabase } from "drizzle-orm/postgres-js";
 import postgres, { type Options, type PostgresType, type Sql } from "postgres";
-const schemaModuleUrl = new URL("./schema/index.js", import.meta.url);
-
-export const schemaPath = schemaModuleUrl.pathname;
+export const schemaPath = fileURLToPath(
+  new URL("./schema/index.js", import.meta.url)
+);

Additionally, please verify:

  1. How will schemaPath be used by consumers? If it's for file system operations, the above fix is essential.
  2. Will this work correctly in your deployment environment (e.g., bundled code, serverless)?

Use fileURLToPath for cross-platform file system path compatibility.

Using URL.pathname to extract file system paths has cross-platform issues. On Windows, pathname returns paths with a leading slash and drive letter (e.g., /C:/Users/...), which is not a valid Windows file system path. Node.js provides fileURLToPath from the url module specifically for converting file URLs to proper file system paths across platforms.

Since schemaPath is a public API export with no internal usage, external consumers will rely on it for runtime schema access (migrations, dynamic imports, or tooling). The cross-platform bug will break file operations on Windows.

Apply this fix:

+import { fileURLToPath } from "url";
+
 import { sql } from "drizzle-orm";
 import { drizzle, type PostgresJsDatabase } from "drizzle-orm/postgres-js";
 import postgres, { type Options, type PostgresType, type Sql } from "postgres";
-const schemaModuleUrl = new URL("./schema/index.js", import.meta.url);
-
-export const schemaPath = schemaModuleUrl.pathname;
+export const schemaPath = fileURLToPath(
+  new URL("./schema/index.js", import.meta.url)
+);
📝 Committable suggestion

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Suggested change
const schemaModuleUrl = new URL("./schema/index.js", import.meta.url);
export const schemaPath = schemaModuleUrl.pathname;
export const schemaPath = fileURLToPath(
new URL("./schema/index.js", import.meta.url)
);
🤖 Prompt for AI Agents
In packages/db/src/index.ts around lines 220 to 222, schemaPath is derived from
schemaModuleUrl.pathname which produces incorrect Windows paths; replace that
with Node's fileURLToPath conversion. Import fileURLToPath from 'url' and use
fileURLToPath(schemaModuleUrl) to compute schemaPath so consumers get a correct
cross-platform filesystem path.
