Usage
vue-firestore supports binding for the both (collections/docs) in realtime, you can bind your properties in two ways using firestore
option or bind them manually with $binding
.
- using
firestore
option.
import Vue from 'vue'
import VueFirestore from 'vue-firestore'
import Firebase from 'firebase'
require('firebase/firestore')
Vue.use(VueFirestore)
var firebaseApp = Firebase.initializeApp({ ... })
const firestore = firebaseApp.firestore();
var vm = new Vue({
el: '#app',
firestore () {
return {
// Collection
persons: firestore.collection('persons'),
// Doc
ford: firestore.collection('cars').doc('ford')
}
}
})
You can pass an object to the firestore()
function.
As you may know, firestore source returns a promise, so you can handle it if it's resolved by resolve
function
or rejected by reject
function, this case is really useful when we want to wait for data to be rendered and do some specific actions.
firestore () {
return {
persons: {
// collection reference.
ref: firestore.collection('persons'),
// Bind the collection as an object if you would like to.
objects: true,
resolve: (data) => {
// collection is resolved
},
reject: (err) => {
// collection is rejected
}
}
}
}
- Manually binding
You can bind your docs/collection manually using this.$binding
, and wait for data to be resolved, this case is really useful when we want to wait for data to be rendered and do some specific actions.
...
mounted () {
// Binding Collections
this.$binding("users", firestore.collection("users"))
.then((users) => {
console.log(users) // => __ob__: Observer
})
// Binding Docs
this.$binding("Ford", firestore.collection("cars").doc("ford"))
.then((ford) => {
console.log(ford) // => __ob__: Observer
}).catch(err => {
console.error(err)
})
}
...
Vue firestore latest release supports binding collections as objects, you can bind the collection manually by this.$bindCollectionAsObject(key, source)
or you can explicitly do that by adding {objects: true}
to firestore()
function, see the previous example above.
The normalized resutls of $bindCollectionAsObject
:
{
tjlAXoQ3VAoNiJcka9: {
firstname: "Jhon",
lastname: "Doe"
},
fb7AcoG3QAoCiJcKa9: {
firstname: "Houssain",
lastname: "Amrani"
}
}
You can get access to firestore properties with this.$firestore
.
Adding Data to collections
var vm = new Vue({
el: '#app',
firestore: function () {
return {
persons: firestore.collection('persons')
}
},
methods:{
addData: function () {
this.$firestore.persons.add({
firstname: "Amrani",
lastname: "Houssain"
})
}
}
})
Each record of the array will contain a .key
property which specifies the key where the record is stored.
The Result of persons
collection will be normalized as :
[
{
".key": "-Jtjl482BaXBCI7brMT8",
"firstname": "Amrani",
"lastname": "Houssain"
},
{
".key": "-JtjlAXoQ3VAoNiJcka9",
"firstname": "John",
"lastname": "Doe"
}
]
You could delete or update a json document of a collection using the property .key
of a given object.
// Vue methods
deletePerson: function (person) {
this.$firestore.persons.doc(person['.key']).delete()
},
updatePerson: function (person) {
this.$firestore.persons.doc(person['.key']).update({
name: "Amrani Houssain"
github: "@amranidev"
})
}
You can customize the name of the .key
property by passing an option when initializing vue-firestore:
require('firebase/firestore')
Vue.use(VueFirestore, {
key: 'id', // the name of the property. Default is '.key'.
enumerable: true // whether it is enumerable or not. Default is true.
})
This would allow you to do person.id
instead of person['.key']
.
