Exploring the filtering capabilities of Firebase using Vue

I am currently trying to enhance the search functionality in my firebase database to enable users to easily locate the product they are looking for.

My current approach involves matching the search query, stored in this.searchText, with the product titles in the firebase database.

return str.filter((product) => {
    return product.title.match(textSearch)
})

However, I have encountered a challenge:

When dealing with a database containing a large number of products, filtering through all of them on the front-end seems inefficient. It would be more effective to implement a targeted query such as:

firebase.database.ref('products').containing('leather shoe')

Unfortunately, I have not yet found a suitable solution to address this issue.

javascript firebase vue.js vuefire

Answer №1

When using Firebase.database.ref('products'), you will receive a Reference, and it's important to note that a Reference does not have a method called containing().

A more suitable method to use in this case is equalTo(), which is explained in more detail here.

For example, if the field containing the value "leather shoe" is named "type", you can achieve the desired result like this:

var ref = firebase.database().ref("products");
ref.orderByChild("type").equalTo("leather shoe").on("child_added", function(snapshot) {
  console.log(snapshot.key);
});

When using vuefire, the approach would be slightly different:

var firebaseApp = firebase.initializeApp({ ... })
var db = firebaseApp.database()

var vm = new Vue({
  el: '#demo',
  firebase: 
    anArray: db.ref("products").orderByChild("type").equalTo("leather shoe")
  }
})
