mongo-go-driver

MongoDB Go Driver is the official Go client library for MongoDB, maintained by MongoDB Inc. It provides native access to MongoDB databases with support for modern Go versions (1.19+) and MongoDB 4.2 or later, including network compression and semantic versioning.

What mongo-go-driver is

A pure Go driver implementing MongoDB's Wire Protocol with context-aware APIs, BSON serialization, connection pooling, and support for Snappy/Zlib/Zstandard compression. Requires Go 1.19+ (1.25+ for test suite) and follows semantic versioning with v2.0 representing a major API redesign.

Quickstart

Get the mongo-go-driver source

Clone the repository and explore it locally.

terminalbash

1git clone https://github.com/mongodb/mongo-go-driver.git2cd mongo-go-driver3# follow the project's README for install & configuration

Best use cases

Backend API Development with MongoDB

Ideal for building REST/GraphQL APIs in Go that need native, idiomatic MongoDB integration without ORM overhead. The driver's context-aware design aligns well with Go's concurrency model and microservice architectures.

Microservices and Cloud-Native Applications

Suits containerized deployments and cloud platforms (AWS, GCP, Azure) where Go's lightweight footprint and this driver's minimal dependencies reduce operational overhead and boot time.

High-Throughput Data Processing

Supports connection pooling, batch operations, and compression to handle bulk inserts, queries, and cursor iteration at scale. Network compression reduces bandwidth costs in distributed systems.

Implementation considerations

Always use context with timeouts (e.g., context.WithTimeout) for all database operations to prevent indefinite hangs and enable graceful shutdown.
Handle connection lifecycle explicitly: defer client.Disconnect() after Connect to avoid resource leaks and ensure clean server disconnection.
Plan for v2.0 migration if upgrading from v1.x; the API has breaking changes. Consult the v2.0 Migration Guide in repository docs.
Test with MongoDB 4.2+ in your environment; older versions are not supported and may have compatibility issues.
Configure error handling patterns for specific error types (e.g., mongo.ErrNoDocuments) to avoid silent failures in production code.

When to avoid it — and what to weigh

Non-Go Codebases — This is Go-specific. Use official MongoDB drivers for Node.js, Python, Java, or other languages; mixing language ecosystems requires additional integration layers.
Legacy Go Projects on Old Versions — Requires Go 1.19+. Older projects stuck on Go 1.16 or earlier cannot use this driver without upgrading the runtime, which may not be feasible in legacy environments.
SQL-Relational Database Preference — This driver is MongoDB-specific. If your application requires ACID transactions, complex joins, or strict schema enforcement, reconsider the database choice before selecting this driver.
Minimal External Dependencies — The driver introduces MongoDB client dependencies and transitive deps. If your project must run in extremely constrained environments (embedded, bare-metal) with zero-dependency requirements, evaluate trade-offs.

License & commercial use

Apache License 2.0 (Apache-2.0). Permissive OSI-approved license allowing commercial use, modification, and distribution with conditions: retain copyright/license notices, provide CHANGES file, and include license copy. No patent indemnity granted.

Apache 2.0 is a permissive OSI license that explicitly permits commercial use without royalties or usage restrictions. Derivative works and closed-source applications are allowed provided Apache headers and license files are retained in source and distributions. No explicit patent protection is included; review your own patent risk if bundling with proprietary codebases. MongoDB Inc. maintains this as the official driver; commercial MongoDB support is available separately from MongoDB.

Security considerations

Connection URIs support authentication (Basic, SCRAM, LDAP, Kerberos, X.509). TLS/SSL is configurable via connection options. OpenSSF Scorecard badge present (linked in README); review current scorecard for vulnerability tracking. Sensitive credentials should not be hardcoded; use environment variables or secure vaults. The driver does not provide application-level encryption; use MongoDB built-in encryption at rest/in transit, or application-level encryption libraries as needed.

Alternatives to consider

mgo (Deprecated)

Older, community-maintained Go driver with simpler API but no longer actively developed. Official mongo-go-driver is the recommended replacement.

sqlc + PostgreSQL

If strong schema enforcement, ACID guarantees, and complex joins are critical, consider SQL alternatives like PostgreSQL with sqlc for type-safe queries instead of MongoDB + Go driver.

MongoDB Node.js Driver

If switching to Node.js/TypeScript for development speed or team preference, provides similar features and MongoDB Inc. support; requires JavaScript/Node.js runtime instead of Go.

mongo-go-driver FAQ

Do I need to use an ORM like GORM with this driver?

Not required. The driver is low-level and supports both direct BSON operations (bson.D, bson.M) and struct marshaling. ORMs like sqlc are for SQL; for MongoDB, the driver itself is sufficient for most use cases.

Is the driver thread-safe?

Yes, mongo.Client and related connection pools are designed for concurrent use. Use contexts to manage per-request timeouts and cancellation in goroutines.

What happens if I upgrade from v1.x to v2.0?

Breaking changes exist. Consult the v2.0 Migration Guide in the repository; common changes include package import paths and API method signatures. Test thoroughly before upgrading production code.

Can I use this driver with MongoDB Atlas?

Yes. Use mongodb+srv:// connection strings provided by MongoDB Atlas; the driver handles DNS seed list discovery automatically.
