🚀 Exploring onMount in SolidJS vs useEffect in ReactJS

When developing with modern frontend frameworks, managing side effects is crucial. Both SolidJS and ReactJS provide elegant ways to handle side effects, but they do so in different ways. In this post, we’ll explore onMount in SolidJS and useEffect in ReactJS with cool examples and diagrams.

🌟 SolidJS: onMount

What is onMount?

In SolidJS, onMount is a lifecycle hook that allows you to run side effects when a component is first rendered. It's a straightforward way to execute code exactly once during the component's lifecycle, making it ideal for initialization tasks like API calls or setting up subscriptions.

Example: Fetching Data Once on Mount

🔥 ReactJS: useEffect

What is useEffect?

In ReactJS, useEffect is a hook that manages side effects in function components. It allows you to perform actions like data fetching, subscriptions, or manually changing the DOM. useEffect runs after the initial render and can be configured to run on state or prop changes.

🔍 Key Differences

• SolidJS onMount:

  • Executes side effects once when the component mounts.
  • Simpler and more intuitive for one-time effects.

• ReactJS useEffect:

  • Executes side effects after render, can re-run on state/prop changes.
  • Requires dependency array to control execution.

Conclusion

Both SolidJS and ReactJS offer powerful tools to manage side effects in your applications. SolidJS’s onMount provides a clean and simple way to run effects once, while React’s useEffect offers flexibility for more complex scenarios. Understanding these tools helps you leverage the strengths of each framework for your projects.
