Fix type error and remove unused import in Neon docs

[andrelandgraf]

This PR removes one unused import and attempts to fix a type error in the Neon docs.

Type error

On docs/get-started/neon-new page on Step 3 - Connect Drizzle ORM to the database.

If you need a synchronous connection, you can use our additional connection API, where you specify a driver connection and pass it to the Drizzle instance.

Code

import { neon } from '@neondatabase/serverless';
import { drizzle } from 'drizzle-orm/neon-serverless';

const sql = neon(process.env.DATABASE_URL!);
const db = drizzle({ client: sql });

Type error for drizzle({ client: sql })

Argument of type '[{ client: NeonQueryFunction<false, false>; }]' is not assignable to parameter of type '[string | NeonClient] | [string | NeonClient, DrizzleConfig<Record<string, never>>] | [DrizzleConfig<Record<string, never>> & (({ ...; } | { ...; }) & { ...; })]'.
  Type '[{ client: NeonQueryFunction<false, false>; }]' is not assignable to type '[string | NeonClient] | [DrizzleConfig<Record<string, never>> & (({ connection: string | PoolConfig; } | { client: NeonClient; }) & { ...; })]'.
    Type '[{ client: NeonQueryFunction<false, false>; }]' is not assignable to type '[string | NeonClient]'.
      Object literal may only specify known properties, and 'client' does not exist in type 'NeonClient'.ts(2345)

Versions

• @neondatabase/serverless: 0.10.4,
• drizzle-orm: 0.39.1

Proposed solution

I think this code example is only meant to showcase passing the neon driver to Drizzle? In this case, I think we just need to update drizzle-orm/neon-serverless to drizzle-orm/neon-http for the default driver.

Not added in this PR, but if this example is meant to showcase the optional ws-based driver (which is brought up earlier on the same page), then I think more changes are needed:

// Use the Pool or Client constructors, instead of the functions described above, when you need:
// session or interactive transaction support, and/or compatibility with node-postgres
// See https://neon.tech/docs/serverless/serverless-driver#use-the-driver-over-websockets

import { drizzle } from 'drizzle-orm/neon-serverless';
import { Pool } from '@neondatabase/serverless';

const pool = new Pool({ connectionString: process.env.DATABASE_URL });
const db = drizzle(pool);

// In environments where ws is not built in:
import { Pool, neonConfig } from '@neondatabase/serverless';
import ws from 'ws';

neonConfig.webSocketConstructor = ws;
