When working with Nuxt.js, I am trying to keep track of the value associated with a key called key1 in the $route.params.
The values for key1 are determined using a function called someFunction().
Is there a way for me to monitor $route.params.key1 as a computed property?
The code below is not functioning as expected:
computed: {
$route.params.key1: someFunction()
}
If you need to manipulate the value using computed properties, you can achieve this by:
computed: {
key1() {
return this.$route.params.key1
}
}
However, if your intention is to perform an action when the value changes, then you should utilize watchers:
watch: {
"$route.params.key1"(value) {
track(value)
}
}
When working with the Composition API in Nuxt 3 or the Nuxt 2 Bridge, you can opt for using useRoute instead of $route. Additionally, utilize the watch option when implementing useAsyncData / useLazyAsyncData and similar functions.
const route = useRoute()
const { data: posts } = await useAsyncData(
'posts',
() => {},
{
watch: [route]
}
)
In my own experience with Nuxt 2 Bridge, I encountered an infinite loop issue (
RangeError: Maximum call stack size exceededconst fetchSomething = () => {}
// A workaround to prevent an infinite loop when using `watch(route)`
const watchFlag = ref(true)
onMounted(() => {
watchFlag.value = false
})
useLazyAsyncData('', () => {
return fetchSomething()
})
watch(watchFlag, async () => {
await fetchSomething()
})
