Como implementar Stores a un proyecto

How can we improve reactivity in Solid with Stores?

Solid provides a powerful tool called stores that allows us to handle complex data such as arrays, objects, maps and sets in a more efficient and ergonomic way. By changing our list of all from a signal to a store, we not only improve the performance of our application, but also simplify development by dealing directly with proxy data.

What is a store in Solid?

A store in Solid is a special primitive designed to handle complex data. Unlike signals, which are functions, stores work as proxies for the data they contain. This means that you can interact with them as you would with normal arrays or objects, but with the advantage that Solid handles reactivity and optimization internally, minimizing the need for global updates to the interface.

How to implement a store in a list of all?

To use a store instead of a signal, start by importing the SolidJS Store primitive. Then, change the functions and properties that depend on the signal to work directly with the store. Here some basic steps in the process:

1. Defining the store:

   import { createStore } from 'solid-js/store';
   const [all, setAll] = createStore([]);

2. Use of proxies:Replaces the functions that treated the array as a signal, since todos is now a proxy for a normal array.

3. Modification logic update:When adding or modifying items in the store, use the set method of the stores, which allows you to specify exactly which index and array property you are modifying:

   setAll(index => all.length, { text: newItem, completed: false });

How to optimize the change of state and content?

Solid facilitates the change of state through specific functions within the stores. This eliminates the need to redefine or clone the entire array when changing a single state or property.

• Changing the state of an element:Use a setter to modify specific properties:

  setAll(index, 'completed', status => !status);

• Editing content:When editing the text of a whole, use the setter to modify directly within the proxy array:

  setAll(index, 'text', newText);

How do you handle adding and removing items?

Modifying an entire list is expensive in terms of resources. Stores allow you to modify individual elements directly, which is more efficient.

• Add elements:Add a new element to the end of the array without the need to recreate the entire array:

  setAll(all.length, { text: newItem, completed: false });

• Remove items:Uses methods like filter to handle the removal simplifying the code and improving performance:

  setAll(all => all.filter((_, idx) => idx !== indexToRemove));

What are the benefits of using stores?

1. Performance optimization: Solid optimizes interface updates through internal memoization and does not require you to update the whole list when modifying a single element.
2. Simplicity and ergonomics: Working with a more direct and natural data model makes it easier to write and read code.
3. Resource savings: It reduces the use of memory and processing cycles, increasing the efficiency of the application.

All in all, stores provide us with a powerful tool for handling complex data, significantly improving reactivity and optimization in our Solid applications. While it may require a change in mindset compared to using signals, the benefits in performance and code clarity are remarkable.
