# How to Use localhost as Web Database Server
This repository contains a Node.js server application that uses PubNub to listen for SQL queries on a specified channel and executes them on an in-memory SQLite database. The results are then sent back to a designated response channel.
Here's a walkthrough of the code and how it works on YouTube:

## Features
- Real-time communication with PubNub.
- In-memory SQLite database for executing SQL queries.
- Simple web-based interface for sending SQL queries and viewing results.
## Requirements
- Node.js (v14 or later)
- PubNub account and API keys
## Setup
### 1. Clone the Repository
```bash
git clone https://github.com/yourusername/pubnub-sqlite-server.git
cd pubnub-sqlite-server
```
### 2. Install Dependencies
```bash
npm install
```
### 3. Configure Environment Variables
Create a `.env` file at the root of the project and add your PubNub keys:
> [Get API Keys](https://admin.pubnub.com/)
```plaintext
PUBNUB_PUBLISH_KEY=your-publish-key
PUBNUB_SUBSCRIBE_KEY=your-subscribe-key
```
### 4. Run the Server
```bash
npm start
```
The Node.js server will start and listen for SQL queries on the `query` channel.
## Web Interface
### 1. Configure PubNub Keys
In the `index.html` file, replace the placeholders with your actual PubNub keys:
> [Get API Keys](https://admin.pubnub.com/)
```javascript
const pubnub = new PubNub({
publishKey: 'your-publish-key', // Replace with your actual PubNub publish key
subscribeKey: 'your-subscribe-key' // Replace with your actual PubNub subscribe key
});
```
### 2. Open `index.html`
Navigate to the `client` directory and open the `index.html` file in your web browser. You can use this simple interface to send SQL queries to the server.
### 3. Use the Interface
- Enter an SQL query in the textarea (e.g., `SELECT * FROM test`).
- Click the "Send Query" button.
- View the result of the query in the response area below the button.
## Example Usage
### Sample SQL Query
```sql
SELECT * FROM test
```
This will return all rows from the `test` table that has been pre-populated with sample data in the in-memory SQLite database.
