mongo-query-match
A utility library that provides a MongoDB-like query language for querying python collections. It's mainly intended to parse objects structured as fundamental types in a similar fashion to what is produced by JSON or YAML parsers.

Yes, if you need MongoDB query syntax for local Python collections and can accept dormant maintenance. No external dependencies and low friction make it safe to add. However, verify the license before use in proprietary contexts, and be aware that the package has not been updated in over a year—do not expect active bug fixes or new features.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.9 or later (supports >=3.9,<4).
- Low install friction with no runtime dependencies.
- Package is marked dormant (558 days since release) with minimal maintenance activity.

What it is and what it does
mongo-query-match is a standalone query engine that lets you write MongoDB-style queries to filter Python dictionaries and lists without connecting to a database. It parses query objects (dicts with operators like $eq, $regex, $elemMatch) and applies them to in-memory Python collections, following MongoDB version 3.4 query semantics. The library is intended for filtering JSON or YAML-like structured data—records with strings, numbers, booleans, nulls, and nested objects.
The package has no external dependencies and installs quickly. It supports most common MongoDB query operators but omits geospatial queries, text search, and projection operators. It's useful when you want MongoDB's expressive query syntax for local data processing, testing, or prototyping without database overhead.
Use it for
- Filter test fixtures or mock data using MongoDB query syntax in unit tests.
- Query JSON or YAML configuration files and data exports without loading them into a database.
- Prototype query logic locally before migrating to a real MongoDB instance.
- Build in-memory query layers for applications that need flexible filtering on structured data.
- Match records against complex criteria in data pipelines or ETL workflows.
