@harlem/core is a state management library for JavaScript applications. It provides a simple and intuitive API for managing application state and handling state changes. With @harlem/core, you can easily define and update reactive state variables, create computed properties, and subscribe to state changes.
Nano Stores is a lightweight and fast state management library for modern web applications. It focuses on simplicity and performance, providing a minimal API that can be used to manage the state of your application. It is only 1.2KB in size and has no third-party dependencies, making it perfect for building small applications and microservices.
Both @harlem/core and nanostores are relatively newer packages and may not have gained as much popularity compared to some more established state management libraries. However, both are increasingly being recognized and adopted by developers in the JavaScript community.
API Design
The API design of @harlem/core and nanostores differs in their approach to state management. @harlem/core follows a Vuex-like pattern and provides a centralized store for managing state. It embraces a mutation-based approach where state changes are made through mutations. Nanostores, on the other hand, follows a more lightweight and functional approach. It provides a collection of stores that can be composed to create complex state management solutions.
Size and Performance
Nanostores is renowned for its small size and lightweight nature. It focuses on delivering efficient performance and utilizes a minimalistic footprint. @harlem/core is also relatively lightweight but may be slightly larger due to the Vuex-inspired patterns it incorporates. Both libraries are designed to be performant and have minimal impact on the overall performance of the application.
Bundle Size Optimization
Nanostores is highly modular, allowing you to import only the specific modules you need. This results in better bundle size optimization as you can cherry-pick the functionality you require. @harlem/core provides a centralized store, which may lead to additional code being included in your bundle, depending on your usage. However, tree-shaking can still be utilized to mitigate unwanted code.
Developer Experience
Both @harlem/core and nanostores aim to provide a good developer experience. They have clear and concise APIs, good documentation, and community support. However, nanostores may have a slightly steeper learning curve for those unfamiliar with functional programming concepts, while @harlem/core adopts a more familiar Vuex-like approach for developers who are already comfortable with that pattern.
Additional Features
While both libraries focus on state management, they also provide additional features to enhance developer productivity. @harlem/core offers built-in support for Vuex plugins and middleware, allowing you to hook into the state management lifecycle. Nanostores includes features such as subscriptions, lifecycles, and derived values to augment the state management capabilities.
