CAUTION
Full application, not a library - significant security concerns for embedding
This isn't actually a reusable library but a complete self-hosted memo application. If you're trying to import it as a dependency, you're pulling in an entire web server, database layer, and frontend assets. The codebase assumes it's running as a standalone service, not as an embeddable component.
From a security perspective, there are concerning patterns. Authentication logic is scattered across multiple packages without clear separation of concerns. Input validation is inconsistent - some endpoints properly sanitize markdown content while others trust client input. Error messages occasionally leak internal paths and database details in development mode that can slip into production. The JWT implementation is functional but lacks refresh token rotation and proper revocation mechanisms.
The database migration system doesn't follow secure-by-default principles - it auto-migrates on startup which can be problematic in production environments. TLS configuration requires manual setup with no secure defaults provided. If you need a memo service, deploy it as-is, but don't try to embed it or use it as a library in your Go project.

Active development with regular security patches being released
SQLite-first design reduces attack surface compared to external database requirements
API authentication uses standard JWT patterns that are reasonably implemented
Not designed as a library - imports bring entire application dependencies
Inconsistent input validation across endpoints creates security gaps
Error handling exposes internal implementation details in some code paths
No secure-by-default TLS configuration or production hardening guides
Best for: Deploying as a standalone self-hosted memo service where you control the entire stack
Avoid if: You need a library to embed memo functionality or require enterprise-grade security controls
CAUTION
Application disguised as a library - lacks reusable SDK design
Memos is fundamentally a self-hosted note-taking application, not a library designed for integration. The Go package structure exposes internal application components rather than providing a coherent SDK or client library. When attempting to use it as a dependency, you'll find yourself importing server handlers, database models, and application-specific logic that weren't designed for external consumption.
The lack of a proper public API surface means no stable interfaces for programmatic interaction. Documentation focuses entirely on deploying and using the application itself, with virtually nothing about integrating it as a dependency. Type definitions exist for internal structures, but they're tightly coupled to the application's implementation details rather than presenting clean abstractions. Error handling follows internal application patterns that don't translate well to library usage.
If you need to interact with a Memos instance programmatically, you're better off using the REST API directly rather than trying to import this package. The codebase is well-structured for its intended purpose as an application, but it simply wasn't designed with library consumers in mind.

Clean internal code organization for the application itself
Well-defined internal data models with proper Go struct tags
No public SDK or client library interface - exposes raw application internals
Documentation is exclusively about running the app, nothing for programmatic integration
No stable API contracts or versioning guarantees for importable packages
Tight coupling between layers makes selective imports impractical
Best for: Deploying and running the Memos application itself, not as a library dependency.
Avoid if: You need a Go client library or SDK to integrate with Memos programmatically - use the REST API instead.
CAUTION
Feature-rich application, but not a library - security concerns for embedding
Memos is a full-fledged application, not a reusable library. If you're considering importing it as a Go module dependency, understand you're pulling in an entire web application with opinionated database schemas, API routes, and frontend assets. The codebase lacks clear separation between application logic and potentially reusable components.
From a security perspective, there are concerns. Authentication flows mix session and token-based approaches without clear documentation on secure defaults. Input validation is inconsistent - some endpoints validate thoroughly while others rely on database constraints. Error messages occasionally leak internal paths and database details. The API uses custom middleware for auth rather than battle-tested frameworks, increasing audit burden.
Dependency management shows typical Go patterns but includes numerous indirect dependencies through the embedded admin UI and storage adapters. CVE response has been reactive rather than proactive. TLS configuration is left to reverse proxy assumptions rather than providing secure defaults. If you must use this, treat it as a standalone service behind proper API gateway controls, not as an embedded component.

Clean REST API design with OpenAPI documentation makes integration straightforward
Multi-storage backend support (local, S3, database) provides deployment flexibility
Active development with regular feature additions and bug fixes
Not designed as a library - importing it pulls entire application dependencies
Inconsistent input validation across endpoints exposes injection risks
Custom authentication middleware increases security audit surface area
Error handling occasionally leaks internal implementation details
Best for: Running as a standalone containerized service with external authentication proxy.
Avoid if: You need a secure, auditable library to embed in existing applications or require FIPS-compliant crypto.
