Sift.js is a tiny JavaScript library that lets you use MongoDB query operators (like $in, $gt, $regex, $elemMatch) to filter arrays and test values in-memory. It works in Node.js and the browser, supports custom operations, and offers tree-shaking to omit unused operators from bundles.

Use cases

• filter arrays of objects with mongodb-style queries in javascript
• use $in, $gt, $regex operators on in-memory data
• build a query filter function for client-side collections
• test single values against a mongo-like query
• filter data without a database
• create custom query operators for filtering

When to choose

• you want MongoDB query syntax for filtering in-memory arrays in Node or the browser
• you need a small, tree-shakeable filtering utility with no database dependency
• you want to share query logic between server and client code

When to avoid

• you need actual MongoDB database queries against a real database
• you need indexing or query optimization for large datasets
• you prefer a different query syntax like JSONata or lodash predicates
