Since your API requires some CORS configuration, here is a simple solution with the JSONplaceholder API of a index + details list collection.
test.vue, pretty much the blog listing in your case
<template>
<div>
<div v-if="$fetchState.pending">Fetching data...</div>
<div v-else>
<div v-for="item in items" :key="item.id">
<nuxt-link :to="`/details/${item.id}`"> View item #{{ item.id }}</nuxt-link>
</div>
</div>
</div>
</template>
<script>
export default {
data() {
return {
items: [],
}
},
async fetch() {
const response = await fetch('https://jsonplaceholder.typicode.com/users')
this.items = await response.json()
},
}
</script>
details.vue, this one needs to be into a pages/details/_id.vue file to work
<template>
<div>
<button @click="$router.push('/test')">Go back to list</button>
<br />
<br />
<div v-if="$fetchState.pending">Fetching details...</div>
<div v-else>{{ details.email }}</div>
</div>
</template>
<script>
export default {
data() {
return {
details: {},
}
},
async fetch() {
const response = await fetch(`https://jsonplaceholder.typicode.com/users/${this.$route.params.id}`)
this.details = await response.json()
},
}
</script>
As you can see, I do only use async/await here and no then for consistency and clarity.
Try this example, then see for fixing the CORS issue. The latter is backend only and not anyhow related to Nuxt. A quick google search may give you plenty of results depending of your backend.
