### Configure Kysely with NeonDialect for Node.js

Source: https://github.com/seveibar/kysely-neon/blob/main/README.md

Illustrates how to initialize Kysely with the NeonDialect for Node.js environments. This example includes the 'ws' import and specifies the 'webSocketConstructor' option for proper WebSocket support, defining a database schema and performing an insert operation.

```typescript
import { GeneratedAlways, Kysely } from "kysely"
import { NeonDialect } from "kysely-neon"
import ws from "ws"

interface Database {
  person: PersonTable
}

interface PersonTable {
  id: GeneratedAlways<number>
  first_name: string
  gender: "male" | "female" | "other"
}

const db = new Kysely<Database>({
  dialect: new NeonDialect({
    connectionString: process.env.DATABASE_URL,
    webSocketConstructor: ws,
  }),
})

await db
  .insertInto("person")
  .values({ first_name: "Jennifer", gender: "female" })
  .returning("id")
  .executeTakeFirstOrThrow()
```

### Configure Kysely with NeonDialect for Edge Runtime

Source: https://github.com/seveibar/kysely-neon/blob/main/README.md

Demonstrates how to initialize Kysely with the NeonDialect for use in Edge runtime environments. It defines a simple database schema for a 'person' table and shows an example of inserting data, connecting via a connection string from environment variables.

```typescript
import { GeneratedAlways, Kysely } from "kysely"
import { NeonDialect } from "kysely-neon"

interface Database {
  person: PersonTable
}

interface PersonTable {
  id: GeneratedAlways<number>
  first_name: string
  gender: "male" | "female" | "other"
}

const db = new Kysely<Database>({
  dialect: new NeonDialect({
    connectionString: process.env.DATABASE_URL,
  }),
})

await db
  .insertInto("person")
  .values({ first_name: "Jennifer", gender: "female" })
  .returning("id")
  .executeTakeFirstOrThrow()
```

### Configure Kysely with Experimental NeonHTTPDialect

Source: https://github.com/seveibar/kysely-neon/blob/main/README.md

Shows how to use the experimental NeonHTTPDialect for Kysely, which enables making stateless HTTPS requests to Neon. This dialect can offer lower latencies but does not support sessions or transactions. It includes a schema definition and an example insert operation.

```typescript
import { GeneratedAlways, Kysely } from "kysely"
import { NeonHTTPDialect } from "kysely-neon"

interface Database {
  person: PersonTable
}

interface PersonTable {
  id: GeneratedAlways<number>
  first_name: string
  gender: "male" | "female" | "other"
}

const db = new Kysely<Database>({
  dialect: new NeonHTTPDialect({
    connectionString: process.env.DATABASE_URL,
  }),
})

await db
  .insertInto("person")
  .values({ first_name: "Jennifer", gender: "female" })
  .returning("id")
  .executeTakeFirstOrThrow()
```
