The shape depends on the runtime:</p>\n<ul>\n<li><strong>Node, persistent process</strong> — a module-level singleton is fine, because\n<code>serverEnv</code> works at module top level there.</li>\n<li><strong>Edge with per-request context (Cloudflare, Vercel Edge)</strong> — read\n<code>serverEnv</code> or the binding <em>inside</em> a factory. Workers env bindings only\nexist per request, so a module-level read bricks the worker at import time.</li>\n</ul>\n<pre><code>// src/db/client.ts — Postgres on Node\nimport { serverEnv } from \"@pracht/core/env/server\";\nimport { drizzle } from \"drizzle-orm/node-postgres\";\nimport { Pool } from \"pg\";\nimport * as schema from \"./schema\";\n\nconst pool = new Pool({ connectionString: serverEnv.DATABASE_URL });\nexport const db = drizzle(pool, { schema });\n</code></pre>\n<p>For Cloudflare D1, register the Cloudflare context type once via the <code>Register</code>\naugmentation. Keep the <code>import</code>: without it the file is a global script and the\ndeclaration replaces <code>@pracht/core</code>'s types instead of extending them.</p>\n<pre><code>// src/env.d.ts\nimport \"@pracht/core\";\n\ndeclare module \"@pracht/core\" {\n  interface Register {\n    context: {\n      env: Env; // wrangler-generated bindings type, includes DB: D1Database\n      executionContext: ExecutionContext;\n    };\n  }\n}\n</code></pre>\n<p>The factory then needs no per-file generics:</p>\n<pre><code>import type { LoaderArgs } from \"@pracht/core\";\nimport { drizzle } from \"drizzle-orm/d1\";\nimport * as schema from \"./schema\";\n\nexport function getDb({ context }: Pick&lt;LoaderArgs, \"context\"&gt;) {\n  return drizzle(context.env.DB, { schema });\n}\n</code></pre>\n<p>Without that augmentation, the inline generic must describe the full context —\n<code>LoaderArgs&lt;{ env: { DB: D1Database }; executionContext: ExecutionContext }&gt;</code> —\nbecause the context is <code>{ env, executionContext }</code>, not the bindings object.</p>\n<h2>Step 4: drizzle.config.ts and scripts</h2>\n<p><code>process.env</code> <em>is</em> fine in <code>drizzle.config.ts</code>: it runs under the drizzle-kit\nCLI on Node, never inside the worker.</p>\n<pre><code>import { defineConfig } from \"drizzle-kit\";\n\nexport default defineConfig({\n  schema: \"./src/db/schema.ts\",\n  out: \"./drizzle/migrations\",\n  dialect: \"postgresql\", // or \"sqlite\" / \"mysql\"\n  dbCredentials: { url: process.env.DATABASE_URL! },\n});\n</code></pre>\n<p><strong>D1 is the exception.</strong> It has no TCP endpoint, so drizzle-kit can only\n<em>generate</em> migrations — applying goes through <code>wrangler</code>. Omit <code>dbCredentials</code>\nentirely (add a <code>driver: \"d1-http\"</code> block with Cloudflare account/database/API\ntoken only if you want <code>drizzle-kit studio</code>), and omit <code>db:push</code>: the\nmigrations-apply flow is the only supported path.
