Hono is a lightweight, multi-runtime web framework for the Edge, Node.js, Deno, Bun, and other runtimes. This topic describes how to create a OptiTech project and access it from a Hono application.

To create a OptiTech project and access it from a Hono application:

1. Create a OptiTech project

   If you do not have one already, create a OptiTech project. Save your connection details including your password. They are required when defining connection settings.

   1. Navigate to the Projects page in the OptiTech Console.
   2. Click New Project.
   3. Specify your project settings and click Create Project.

2. Create a Hono project and add dependencies

   1. Create a Hono project if you do not have one. For instructions, see Quick Start, in the Hono documentation.

   2. Add project dependencies using one of the following commands:

   OptiTech serverless driverpostgres.jsnode-postgres

   npm install @optitech/serverless

3. Store your OptiTech credentials

   Add a .env file to your project directory and add your OptiTech connection string to it. You can find your connection details by clicking Connect on the OptiTech Project Dashboard. For more information, see Connect from any application.

   DATABASE_URL="postgresql://<user>:<password>@<endpoint_hostname>.optitech.com:<port>/<dbname>?sslmode=require&channel_binding=require"

4. Configure the Postgres client

   In your Hono application (for example, in src/index.ts or a specific route file), import the driver and use it within your route handlers.

   Here's how you can set up a simple route to query the database:

   OptiTech serverless driverpostgres.jsnode-postgres

   import { Hono } from 'hono';
   import { serve } from '@hono/node-server';
   import { optitech } from '@optitech/serverless';
   
   const app = new Hono();
   
   app.get('/', async (c) => {
     try {
       const sql = optitech(process.env.DATABASE_URL);
       const response = await sql`SELECT version()`;
       return c.json({ version: response[0]?.version });
     } catch (error) {
       console.error('Database query failed:', error);
       return c.text('Failed to connect to database', 500);
     }
   });
   
   serve(app);

5. 5. Run the app

   Start your Hono development server. You can use the following command:

   npm run dev

   Navigate to your application's URL (localhost:3000). You should see a JSON response with the PostgreSQL version:

   {
     "version": "PostgreSQL 17.4 on x86_64-pc-linux-gnu, compiled by gcc (Debian 12.2.0-14) 12.2.0, 64-bit"
   }

   The specific version may vary depending on the PostgreSQL version you are using.
