I am working on pagination in vue and firebase and it is working fine. But now i want to go directly to the nth page using pagination. But firebase doesn't allow me to do that. Please guide me on how can fix this.
onMounted(() => {
totalLength()
if (lastDoc.value && currentPosition.value == 'next') {
next()
} else if (lastDoc.value && currentPosition.value == 'prev') {
prev()
} else {
loadPapers()
}
})
const next = () => {
savedTopifyPapers
.orderBy('timeStamp', 'asc')
.startAfter(lastDoc.value)
.limit(1)
.onSnapshot((snapshot) => {
lastDoc.value = snapshot.docs[snapshot.docs.length - 1]
if (snapshot.empty) {
loadingData.value = false
}
papersData.value = snapshot.docs.map((doc) => {
const data = doc.data()
const id = doc.id
loadingData.value = false
return { id, ...data }
})
papersDataLength.value = papersData.value.length
})
}
const prev = () => {
savedTopifyPapers
.orderBy('timeStamp', 'asc')
.endBefore(lastDoc.value)
.limit(1)
.onSnapshot((snapshot) => {
lastDoc.value = snapshot.docs[snapshot.docs.length - 1]
if (snapshot.empty) {
loadingData.value = false
}
papersData.value = snapshot.docs.map((doc) => {
const data = doc.data()
const id = doc.id
loadingData.value = false
return { id, ...data }
})
papersDataLength.value = papersData.value.length
})
}
const totalLength = () => {
savedTopifyPapers.get().then((response) => {
totalPaperLength.value = response.docs.length
})
}
const loadPapers = () => {
let t = savedTopifyPapers.orderBy('timeStamp', 'asc').limit(1)
console.log(lastDoc.value)
if (lastDoc.value) {
t = savedTopifyPapers.startAfter(lastDoc.value)
}
t.onSnapshot((snapshot) => {
console.log(snapshot.empty)
const _lastDoc = snapshot.docs[snapshot.docs.length - 1]
if (_lastDoc) {
lastDoc.value = _lastDoc
}
if (snapshot.empty) {
loadingData.value = false
}
papersData.value = snapshot.docs.map((doc) => {
const data = doc.data()
const id = doc.id
loadingData.value = false
return { id, ...data }
})
papersDataLength.value = papersData.value.length
})
}
Any solution appreciated!
