MongoDB Example 🍃

This example shows how to use GoTrust with MongoDB as the user store.

Prerequisites

• MongoDB running locally or accessible via connection string
• Go 1.19+

Setup

1. Start MongoDB (if not running):

# Using Docker
docker run -d -p 27017:27017 --name mongodb mongo:latest

# Or use your existing MongoDB installation

1. Set environment variables:

export JWT_SECRET="your-secret-key-at-least-32-characters"
export MONGO_URI="mongodb://localhost:27017"  # Optional, defaults to localhost

1. Install dependencies:

go mod init mongodb-example
go get github.com/mayurrawte/gotrust
go get go.mongodb.org/mongo-driver/mongo
go get github.com/labstack/echo/v4

1. Run the example:

go run main.go

Testing the API

Create a user:

curl -X POST http://localhost:8080/auth/signup \
  -H "Content-Type: application/json" \
  -d '{
    "email": "john@example.com",
    "password": "securepass123",
    "name": "John Doe"
  }'

Sign in:

curl -X POST http://localhost:8080/auth/signin \
  -H "Content-Type: application/json" \
  -d '{
    "email": "john@example.com",
    "password": "securepass123"
  }'

Access protected route:

curl -X GET http://localhost:8080/api/profile \
  -H "Authorization: Bearer YOUR_TOKEN_HERE"

MongoDB Schema

The users collection will have documents like:

{
  "_id": ObjectId("..."),
  "email": "john@example.com",
  "name": "John Doe",
  "avatar_url": "",
  "provider": "local",
  "password": "$2a$10$...",  // bcrypt hash
  "created_at": ISODate("2024-01-01T00:00:00Z"),
  "updated_at": ISODate("2024-01-01T00:00:00Z")
}

Notes

• The email field has a unique index to prevent duplicates
• Passwords are hashed using bcrypt
• OAuth users won't have a password field
• The example uses in-memory session storage; for production, use Redis
