The choice between Vue.js and Svelte is often a personal choice of the developer taking into account the specific project and its requirements. Here are some of the thoughts of experienced web developers who used both frameworks in their practice:
“ I personally find svelte component structure to be so similar to Vue SFC without <template>. I can see a strong case of moving from React to Svelte or React to Vue because of the predictable component structure”.
“I believe Vue is really wordy. Because Svelte is extremely lean, you can create and understand the code more quickly and with less fussing about syntax. Less code is always simpler to understand, write, and debug, therefore this is a significant gain in the quality of life”.
“For a few years now I've been using both depending on project. There's a lot of small differences that I weigh project-by-project.
- Vue has more of an ecosystem, e.g. vuex and vue-i18n. Sometimes you need them.
- I like sveltekit's routing, it's easier out of the box. But I feel like it's slightly harder to extend and customize compared to Vue Router.
- Svelte does not require a single top level element in the template. That's quite annoying in Vue.
- Sometimes Vue templates are nicer because of the v-* directives that doesn't require a separate line for the control structure. However when you want to put multiple sibling elements in the v-if/v-for the Vue solution becomes less natural.
- Vue's v-for seems to require keys to work properly a bit more often than Svelte's #each”.
“Reactivity is the main point where Svelte and Vue differ. Svelte treats reactivity in an immutable fashion. Variables only react when reassigned.
Vue on the other hand relies on mutability. Variables (reactive, ref) only react when mutated.
There are upsides and downsides to both. Svelte makes it easier to work with primitives, but Vue makes it easier to work with arrays and complex objects. With Vue, you need to ensure you're passing around refs and not destructuring to the primitive values to maintain reactivity. With Svelte you need to do things like `myArray = [...myArray, newValue]` instead of just doing `myArray.push(newValue)`” .
So, both frameworks are widely used by developers, and both have its pros and cons.
Future of Vue.js and Svelte
