Dealing with CORS error when making requests to Firebase Realtime Database API within a Vue project

I am currently working with vue-2 and I need to perform a shallow query on the Firebase real-time database by fetching an API. However, when running on my development server, I encounter a CORS blocked issue. What steps should I take to resolve this? PS: I am also utilizing Vuefire

created(){
    var apiUrl = 'https://console.firebase.google.com/u/4/project/enajori-45094/database/enajori-45094/data/Admin/Data%20Collection/Paying%20Guest';
    fetch(apiUrl).then(response => {
      return response.json();
    }).then(data => {
      console.log(data);
    }).catch(err => {
        console.log(err);
    });
}

I am encountering a CORS error as shown in this image

Answer №1

When using Firebase's REST API, it is important to note that it only responds to HTTPS requests. If your localhost does not have SSL enabled, your requests will inevitably fail, regardless of any attempts you make. Additionally, the URI must always end with the name of the table, such as 'something.json'.

It is highly recommended to utilize the Firebase SDK for a smoother experience.

Answer №2

I find it puzzling why one would opt to utilize a URL linking to the Firebase console in order to access the database. Console URLs are designed for human interaction, not for automated programs.

The recommended approach is to make use of the provided Javascript SDK for data access. This will automatically handle CORS issues and provide a more seamless method for reading and writing data. In cases where the SDK cannot be used, there is always the option of utilizing the REST API. However, it is advised not to rely on console URLs for this purpose at all.
