name: mongodb description: Use for managing MongoDB.

Usage

Copybun {dir}/scripts/query.ts "<query>"

Examples

Copy# Simple read
bun {dir}/scripts/query.ts "db.collection('users').findOne()"

# Query with ObjectId
bun {dir}/scripts/query.ts "db.collection('users').findOne({ _id: new ObjectId('...') })"

# Multi-step update (Batching)
bun {dir}/scripts/query.ts "Promise.all([
  db.collection('rewards').deleteMany({ userId: new ObjectId('...') }),
  db.collection('users').updateOne({ _id: new ObjectId('...') }, { \$set: { 'dailyXp.count': 0 } })
])"

Tips

• Use query.ts over writing one-off scripts. Use Promise.all for parallel operations or an IIFE (async () => { ... })() for complex multi-step logic.
• ObjectId is globally available in the query context.
• Use limit(1) or findOne() to understand schema without wasting tokens.
• Use countDocuments() instead of fetching docs for existence checks.
