# Hono - Prisma - Postgres Sample Application
2+
3+
This is a simple Todo application built using **Hono**, **Prisma**, **PostgreSQL**, **JWT**, and **TypeScript**. The project also integrates with **Keploy** for recording and running test cases. The package manager used is **Bun**.
4+
5+
## Features
6+
7+
- User authentication with JWT
8+
- CRUD operations for Todo items
9+
- API testing with Keploy
10+
- Docker support for containerized deployment
11+
12+
## Tech Stack
13+
14+
- **Framework**: Hono
15+
- **Database**: PostgreSQL
16+
- **ORM**: Prisma
17+
- **Authentication**: JWT
18+
- **Language**: TypeScript
19+
- **Package Manager**: Bun
20+
- **Containerization**: Docker
21+
22+
## API Endpoints
23+
24+
### Auth Routes
25+
26+
- GET / - Test response
27+
- POST /register - Register a new user
28+
- POST /login - Log in a user
29+
30+
### Protected Todo Routes (require authentication)
31+
32+
- POST /todos - Create a new todo
33+
- GET /todos - Retrieve all todos
34+
- PUT /todos - Update a todo
35+
- DELETE /todos - Delete a todo
36+
37+
## Setup Instructions
38+
39+
There are two ways to run this application:
40+
41+
### Method 1: Local Development
42+
43+
#### Prerequisites
44+
45+
- Node.js (with Bun installed)
46+
- PostgreSQL installed and running
47+
- Prisma CLI installed globally (npm install -g prisma)
48+
- Keploy installed (Follow [documentation](https://keploy.io/docs/server/installation/) for installation)
49+
50+
#### Steps to Run
51+
52+
1. **Clone the Repository**
53+
54+
```bash
55+
git clone <repository-url>
56+
cd <repository-folder>
57+
```
58+
59+
2. **Install Dependencies**
60+
61+
```bash
62+
bun install
63+
```
64+
65+
3. **Setup .env**
66+
Create a .env file and add your Postgres database url:
67+
68+
```bash
69+
DATABASE_URL="postgresql://postgres:password@localhost:5432/my_pgserver?schema=public"
70+
```
71+
72+
4. **Setup Database**
73+
74+
```bash
75+
npx prisma migrate dev --name init
76+
```
77+
78+
5. **Run the Application**
79+
```bash
80+
bun dev
81+
```
82+
83+
### Method 2: Docker Deployment
84+
85+
#### Prerequisites
86+
87+
- Docker and Docker Compose installed
88+
- Keploy installed
89+
90+
#### Steps to Run
91+
92+
1. **Create Docker Network**
93+
94+
```bash
95+
docker network create keploy-network
96+
```
97+
98+
> **Note:** While this network should be created automatically during installation, this command ensures it exists.
99+
100+
```
101+
102+
```
103+
104+
2. **Start the Application**
105+
```bash
106+
docker-compose up --build
107+
```
108+
109+
## Keploy Integration
110+
111+
Keploy allows you to record and test API requests and responses. There are two methods to use Keploy with this project:
112+
113+
### Method 1: Local Testing
114+
115+
1. **Recording Test Cases**
116+
117+
```bash
118+
keploy record -c "bun dev"
119+
```
120+
121+
2. **Running Test Cases**
122+
```bash
123+
keploy test -c "bun dev" --delay 10
124+
```
125+
126+
### Method 2: Docker-based Testing
127+
128+
1. **Recording Test Cases**
129+
130+
```bash
131+
keploy record -c "docker compose up" --container-name "hono-prisma-postgres" -n "keploy-network"
132+
```
133+
134+
2. **Running Test Cases**
135+
```bash
136+
keploy test -c "docker compose up" --container-name "hono-prisma-postgres" -n "keploy-network"
137+
```
138+
139+
## Notes
140+
141+
- Ensure your database is properly configured in the prisma.schema file and the environment variables are set.
142+
- Use the authMiddleware to protect routes requiring user authentication.
143+
- For CORS support, the application includes:
144+
```typescript
145+
app.use("/*", cors());
146+
```
147+
148+
## Common Issues
149+
150+
### PrismaClientInitializationError with Keploy Recording
151+
152+
When running Keploy record command with database interactions, you might encounter a PrismaClientInitializationError. This often occurs due to SSL connection issues with PostgreSQL.
153+
154+
#### Symptoms
155+
156+
When executing the Keploy record command, you might encounter database connectivity issues, particularly when making API calls that interact with the database. The PostgreSQL logs typically show SSL-related errors like:
157+
158+
```
159+
2024-12-25 13:42:23.035 IST [123887] [unknown]@[unknown] LOG: could not accept SSL connection: EOF detected
160+
2024-12-25 14:41:45.859 IST [172605] [unknown]@[unknown] LOG: could not accept SSL connection: EOF detected
161+
```
162+
163+
#### Resolution (Ubuntu/Linux)
164+
165+
1. **Access PostgreSQL Configuration**
166+
167+
```bash
168+
sudo nano /etc/postgresql/12/main/postgresql.conf
169+
```
170+
171+
2. **Modify SSL Settings**
172+
173+
- Locate the SSL configuration line
174+
- Change ssl = on to ssl = off
175+
176+
3. **Restart PostgreSQL**
177+
```bash
178+
sudo service postgresql restart
179+
```
180+
181+
#### Important Security Note
182+
183+
⚠️ Disabling SSL should only be done in development environments. For production deployments:
184+
185+
- Keep SSL enabled
186+
- Properly configure SSL certificates
187+
- Follow security best practices for database connections
188+
189+
#### Additional Considerations
190+
191+
- Make sure your database connection string in .env is properly configured
192+
- If you're using a different PostgreSQL version, the configuration file path might vary
193+
- Always backup your configuration files before making changes
