v0.15.2(over 1 year ago)
Waterline is a data persistence layer for Node.js applications that provides a simple data access layer with support for various databases. It offers a unified API for interacting with different database systems, allowing developers to switch between databases without changing their code significantly. Waterline supports features like schemaless data modeling, associations, and validation.
Both @mikro-orm/core and waterline are popular npm packages, but @mikro-orm/core has gained significant popularity in recent years due to its simplicity and developer-friendly ORM (Object-Relational Mapping) approach. Waterline, on the other hand, has been around for longer and has a larger community following.
Architecture
@mikro-orm/core follows a modern, minimalistic approach to ORM. It provides a simple yet powerful API, with a focus on code-first development and easy integration with various SQL and NoSQL databases. Waterline, on the other hand, is a more traditional ORM with support for multiple databases, including MySQL, PostgreSQL, MongoDB, and more.
Features
@mikro-orm/core provides a comprehensive set of features for ORM operations, including entity management, query building, database migrations, and schema generation. It also supports TypeScript out of the box. Waterline, on the other hand, offers a broader range of features such as support for associations, transactions, and data validations.
Performance
Both packages strive for good performance, but @mikro-orm/core is known for its lightweight footprint and efficient query generation, which can result in faster database operations. Waterline, on the other hand, may introduce additional overhead due to its more comprehensive feature set and compatibility layer for multiple databases.
Documentation and Community
Both @mikro-orm/core and waterline have well-documented APIs and active communities. However, @mikro-orm/core provides more up-to-date and detailed documentation, making it easier for developers to get started and find answers to their questions. It also has a more focused and responsive community.
Flexibility
While @mikro-orm/core focuses on simplicity and ease of use, it may not have the same level of flexibility and extensibility as waterline. Waterline provides a plugin system that allows developers to extend its functionality and integrate with additional third-party libraries or custom adapters for specific databases.
