Practical Exercise:

Let’s build a backend for a TodoList application using HonoJS, PostgreSQL, and Drizzle ORM in TypeScript, we will create a CRUD API. This guide will walk you through the technical details of setting up the environment, defining the database schema, and implementing the API endpoints.

Step 1: Setup Your Environment

1. Initialize the Project:

   • Create a new directory for your project and navigate into it.

   • Initialize a new Node.js project (insure that node is installed on your machine):

       npm init -y
     

2. Install Dependencies:

   • Install the necessary packages:

       npm install hono drizzle-orm pg dotenv
     

3. Setup TypeScript:

   • Install TypeScript and necessary types:

       npm install --save-dev typescript @types/node
     

   • Initialize TypeScript configuration:

       npx tsc --init
     

1. Configure Environment Variables:

   Database Setup

   For a faster setup of a PostgreSQL database, you can use an online managed database service. Here are two popular options:

   1. Heroku Postgres: Heroku offers a fully managed PostgreSQL service that is optimized for developers. It provides a scalable and secure environment with features like automated backups, replication, and easy scaling. You can quickly set up a database using the Heroku CLI with a simple command, and it integrates well with other Heroku services [1].

   2. DigitalOcean Managed Databases: DigitalOcean provides a managed PostgreSQL service that handles the complexity of database administration. It offers features like automated backups, scaling, and high availability. You can launch a database cluster with just a few clicks and manage it through a user-friendly interface or API [2].

These services allow you to focus on building your application without worrying about the underlying database infrastructure.

• Create a .env file in the root of your project and add your PostgreSQL connection details (it looks like the string below):

    DATABASE_URL=postgres://user:password@localhost:5432/todolist
  

Step 2: Define Your Database Schema

1. Create Schema File:

   • In the src/db directory, create a schema.ts file to define your tables:

       import { pgTable, serial, varchar, boolean } from "drizzle-orm/pg-core";
     
       export const todosTable = pgTable("todos", {
         id: serial().primaryKey().generatedAlwaysAsIdentity(),
         title: varchar({ length: 255 }).notNull(),
         completed: boolean().notNull().default(false),
       });
     

2. Setup Drizzle ORM:

   • Create an index.ts file in the src/db directory to initialize the database connection:

       import 'dotenv/config';
       import { drizzle } from 'drizzle-orm/node-postgres';
       import { Pool } from 'pg';
     
       const pool = new Pool({
         connectionString: process.env.DATABASE_URL!,
       });
     
       export const db = drizzle({ client: pool });
     

Step 3: Build Your API with HonoJS

1. Create the Server:

   • In the src directory, create an app.ts file to set up the HonoJS server:

       import { Hono } from 'hono';
       import { db } from './db';
       import { todosTable } from './db/schema';
     
       const app = new Hono();
     
       // Get all todos
       app.get('/todos', async (c) => {
         const todos = await db.select().from(todosTable);
         return c.json(todos);
       });
     
       // Create a new todo
       app.post('/todos', async (c) => {
         const { title } = await c.req.json();
         const newTodo = await db.insert(todosTable).values({ title });
         return c.json(newTodo);
       });
     
       // Update a todo
       app.put('/todos/:id', async (c) => {
         const { id } = c.req.param();
         const { title, completed } = await c.req.json();
         await db.update(todosTable).set({ title, completed }).where(todosTable.id.eq(id));
         return c.text('Todo updated');
       });
     
       // Delete a todo
       app.delete('/todos/:id', async (c) => {
         const { id } = c.req.param();
         await db.delete(todosTable).where(todosTable.id.eq(id));
         return c.text('Todo deleted');
       });
     
       export default app;
     

2. Run the Server:

   • Create an index.ts file to start the server:

       import app from './app';
     
       app.listen({ port: 3000 }, () => {
         console.log('Server running on http://localhost:3000');
       });
     

Step 4: Run and Test Your Application

1. Compile TypeScript:

   • Compile your TypeScript files:

       npx tsc
     

2. Start the Server:

   • Run the compiled JavaScript files:

       node dist/index.js
     

3. Test the API:

   • Use a tool like Postman or curl to test the CRUD operations on the /todos endpoint.

Step 5: Deploy to a Serverless Platform

• Use HonoJS's multi-runtime support to deploy your application on platforms like Vercel or AWS Lambda. Ensure your environment variables are configured correctly for the deployment platform.

By following these steps, you will have a fully functional TodoList backend application with a CRUD API using HonoJS, PostgreSQL, and Drizzle ORM in TypeScript. This setup provides a robust foundation for building scalable and efficient backend services.
