State Management Showdown: Redux vs MobX
When it comes to managing state in large frontend applications, two popular libraries stand out: Redux and MobX. In this article, we’ll delve into the key features of each library, comparing their strengths and weaknesses.
What is Redux?
Redux is a state management solution that combines Flux and functional programming concepts. Its core principles include:
- A single store providing a single source of truth
- Immutable state
- Actions invoking changes to the store
- Reducers updating state
What is MobX?
MobX is a state management solution that helps manage local state within an application. Its core principles include:
- Multiple stores storing the state of an application
- Derivations automatically updating when the state changes
- Actions changing the state
Popularity Contest
Before choosing between Redux and MobX, let’s examine their popularity. According to Google Trends, Redux has maintained a significant advantage over the past year. The State of JavaScript 2020 survey also reports that 67% of respondents use Redux, while only 13% use MobX.
Winner: Redux takes the win for most popular.
Learning Curve
Developers often complain about Redux’s steep learning curve. However, MobX is known for being easier to learn, especially for developers familiar with object-oriented programming.
Winner: MobX wins for its easier learning experience.
Single Store vs Multiple Stores
Redux uses a single store, while MobX allows multiple stores. This decision ultimately depends on personal preference.
Data Structure
Redux uses plain JavaScript objects, requiring manual update tracking. MobX, on the other hand, uses observable data, automatically tracking changes.
Winner: MobX wins for automatically tracking updates.
Pure vs Impure Functions
Redux enforces pure functions, making it more predictable and easier to revert state updates. MobX, however, allows impure functions, which can be harder to test and maintain.
Winner: Redux wins for its pure functions.
Boilerplate Code
One of the biggest complaints about Redux is the amount of boilerplate code required. MobX, however, requires much less boilerplate code.
Winner: MobX wins for its easy setup and learning curve.
Developer Communities
Redux has a larger and more active community, with better debugging support and more contributors.
Winner: Redux takes the win for its adaptability and popularity among developers.
Scalability
Redux’s opinionated and pure nature makes it easier to scale than MobX.
Winner: Redux wins for its scalability.
Ultimately, the choice between Redux and MobX depends on your specific needs and preferences. If you’re looking for a more popular and scalable solution, Redux might be the better choice. However, if you want a simpler and easier-to-learn solution, MobX could be the way to go.
