Query Operators¶

Master MongoDB-style query operators in @arcaelas/collection.

Comparison Operators¶

collection.filter({ age: { $eq: 25 } });
// or shorthand
collection.filter({ age: 25 });

collection.filter({ age: { $gt: 18 } });

collection.filter({ age: { $gte: 18 } });

collection.filter({ age: { $lt: 65 } });

collection.filter({ age: { $lte: 65 } });

collection.filter({ 
  $not: { age: { $lt: 18 } }
});

collection.filter({
  status: { $in: ['active', 'pending', 'verified'] }
});

collection.filter({
  skills: { $contains: 'TypeScript' }
});

For convenience, use shorthand aliases:

// These are equivalent
collection.where('age', '>=', 18);
collection.filter({ age: { $gte: 18 } });
