# psql

Deno implementation of the Postgresql frontend-backend/client-server protocol

## Getting started

```typescript

// deno run --allow-net --allow-read --unstable mod.ts

import { 

    Client,

    ObjectCursor

} from 'https://deno.land/x/psql/mod.ts'

const client = new Client({

    host: 'localhost',

    port: 5432,

    user: 'postgres',

    password: 'postgres'

})

await client.connect()

// simple query, result as array with default cursor

{

    const cursor = client.cursor()

    const result = await cursor.query('select id, name from people')

    console.log(result) // [[1, 'john'], [2, 'lucy'], ...]

}

// simple query with paramters, result as object with ObjectCursor

// You play `psql` with with `es6 tagged template string`, which looks like magic.

{

    const objectCursor = client.cursor(ObjectCursor)

    // const result = await objectCursor.query('select id, name from people where id < $1', [3, ])

    const result = await objectCursor.query`select id, name from people where id < ${3}`

    console.log(result) // [{id: 1, name: 'john'}, {id: 2, name: 'lucy'}]

}

// insert with paramters, return last insert id

{

    const cursor = client.cursor()

    const sql = `insert into people (name, ) values ($1, ) returning id`

    const result = await cursor.query(sql, ['david'])

    console.log(result) // 3

}

await client.close()

```
