MongoDB Database Explorer

Use this skill when you need to explore the MongoDB database to understand data structure, verify existing records, or investigate database state.

When to Use

• Understanding what data exists in collections
• Checking collection schemas and indexes
• Counting documents matching certain criteria
• Viewing sample documents
• Debugging data-related issues
• Verifying database state after operations

Quick Exploration Commands

Use mongosh or a MongoDB client to explore the database:

Copy# Connect to MongoDB
mongosh mongodb://localhost:27017/freelancelyst

# Show all collections
show collections

# Count documents in a collection
db.users.countDocuments()
db.blogposts.countDocuments()

# View sample documents
db.users.find().limit(5).pretty()
db.blogposts.find().limit(5).pretty()

# Query with filters
db.blogposts.find({ status: "published" }).limit(10).pretty()
db.users.find({ roles: "admin" }).pretty()

# Aggregate examples
db.blogposts.aggregate([
  { $group: { _id: "$status", count: { $sum: 1 } } }
])

Database Schema Overview

The database has the following collections:

Users

Collection: users

Copy{
  _id: ObjectId,
  name: string,
  email: string,
  password: string,  // bcrypt hashed
  roles: string[],   // ['user'] or ['admin']
  createdAt: Date,
  updatedAt: Date
}

Blog Posts

Collection: blogposts

Copy{
  _id: ObjectId,
  slug: string,      // unique
  status: 'draft' | 'published' | 'archived',
  publishedAt: Date | null,
  coverImage: string | null,
  owner: ObjectId,   // ref: users
  category: ObjectId | null,  // ref: blogcategories
  tags: ObjectId[],  // refs: blogtags
  translations: [
    { langCode: 'en' | 'fa', title: string, content: string, excerpt: string }
  ],
  createdAt: Date,
  updatedAt: Date
}

Blog Categories

Collection: blogcategories

Copy{
  _id: ObjectId,
  slug: string,      // unique
  translations: [
    { langCode: 'en' | 'fa', name: string }
  ],
  createdAt: Date,
  updatedAt: Date
}

Blog Tags

Collection: blogtags

Copy{
  _id: ObjectId,
  slug: string,      // unique
  translations: [
    { langCode: 'en' | 'fa', name: string }
  ],
  createdAt: Date,
  updatedAt: Date
}

Project Applications

Collection: projectapplications

Copy{
  _id: ObjectId,
  title: string,
  description: string,
  budgetEstimate: string,
  deadline: string,
  clientEmail: string | null,
  utm: object | null,  // UTM tracking params
  createdAt: Date,
  updatedAt: Date
}

Freelancer Applications

Collection: freelancerapplications

Copy{
  _id: ObjectId,
  fullName: string,
  email: string,
  skillTags: string,
  description: string,
  utm: object | null,  // UTM tracking params
  createdAt: Date,
  updatedAt: Date
}

Common Queries

Find posts with translations in specific language

Copydb.blogposts.find({
  "translations.langCode": "en"
}).pretty()

Get published posts with category populated

Copydb.blogposts.aggregate([
  { $match: { status: "published" } },
  { $lookup: {
    from: "blogcategories",
    localField: "category",
    foreignField: "_id",
    as: "categoryData"
  }},
  { $limit: 5 }
])

Count applications by month

Copydb.projectapplications.aggregate([
  { $group: {
    _id: { $month: "$createdAt" },
    count: { $sum: 1 }
  }}
])

Important Notes

1. Environment: Ensure MONGODB_URI is set in your .env.local file
2. Read-Only: This skill is for exploration only. Never modify data through raw queries.
3. Sensitive Data: Be careful with password hashes - don't log them in plain text
4. Performance: Use limits on large collections to avoid slow queries
5. Translations: Remember blog entities use embedded translation arrays
