Managing Multiple Svelte Stores in One File

Svelte is an incredible framework for building user interfaces due to its reactivity and simplicity. However, when trying to manage multiple Svelte stores within a single JavaScript file, developers often face the challenge of conflicting names for subscribe, set, and update methods. If you’ve encountered this issue, you're not alone. In this guide, we will explore effective methods to overcome this challenge.

The Problem at Hand

When you attempt to create multiple writable stores in a single file, the default destructuring syntax leads to naming conflicts. For instance, if you define two stores as follows:

In this snippet, both Store1 and Store2 end up using the same names for their methods, leading to confusion and errors due to the duplicated names.

How to Solve the Naming Conflict

To manage multiple Svelte stores effectively within one file, you essentially have two strategies at your disposal: modifying the way you destructure the writable store object, or assigning new variable names. Let’s break these solutions down.

1. Avoiding Destructuring

One straightforward option is to avoid destructuring the object returned by the writable function altogether. Instead, you can directly reference the methods later on:

In this approach, you create a distinct variable (store1Writable) that encapsulates all the methods. You can call store1Writable.subscribe, store1Writable.set, and store1Writable.update as required.

2. Assigning New Variable Names

Another effective method is to destructure with renamed properties. Here’s how you can do that:

By renaming your destructured properties, you can eliminate any potential conflicts. Just make sure to do the same when you create your second writable store:

Putting It All Together

Here’s an example that combines both strategies for clarity:

Conclusion

Working with multiple Svelte stores in a single file doesn’t have to be complicated. By utilizing destructuring with new variable names or simply avoiding destructuring, you can keep your code clean and maintainable. Whether you’re building small widgets or large applications, mastering this technique will prove beneficial in managing complex state patterns.
