Introduction

In this article, we will explore how to build a workout tracker app using Vue 3 and Supabase. Vue 3 is the latest version of the popular JavaScript framework, Vue.js, and Supabase is an open-source Backend-as-a-Service (BaaS) alternative to Firebase. By combining these two technologies, we can create a powerful and scalable workout tracking application.

Setting up Vue 3

To get started, make sure you have Vue 3 installed on your machine. You can install Vue 3 by running the following command in your terminal:

npm install -g @vue/cli

Once you have Vue 3 installed, you can create a new Vue project by running the following command:

vue create workout-tracker

This will create a new Vue project with the name “workout-tracker”.

Integrating Supabase

Now that we have our Vue project set up, we can integrate Supabase as our backend. Supabase provides a RESTful API and a real-time database, making it a perfect fit for our workout tracker app.

First, sign up for a free Supabase account and create a new project. Once you have your project set up, you can retrieve your Supabase URL and API key. These will be used to connect to your Supabase backend from your Vue app.

To connect to Supabase from your Vue app, you can use the official Supabase JavaScript library. Install it by running the following command:

npm install @supabase/supabase-js

After installing the library, you can import it in your Vue app and initialize a new Supabase client using your Supabase URL and API key.

import { createClient } from '@supabase/supabase-js';

const supabaseUrl = 'YOUR_SUPABASE_URL';
const supabaseKey = 'YOUR_SUPABASE_API_KEY';
const supabase = createClient(supabaseUrl, supabaseKey);

export default {
  data() {
    return {
      workouts: []
    };
  },
  created() {
    this.fetchWorkouts();
  },
  methods: {
    async fetchWorkouts() {
      const { data: workouts, error } = await supabase
        .from('workouts')
        .select('*');
      
      if (error) {
        console.error(error);
      } else {
        this.workouts = workouts;
      }
    }
  }
};
    

This code fetches the workouts data from the “workouts” table in your Supabase project and assigns it to the “workouts” variable in your Vue component’s data object. You can then use this data to display and manipulate workouts in your app.

Building the Workout Tracker App

With Vue 3 set up and Supabase integrated, you can now start building your workout tracker app. The app will allow users to create, read, update, and delete workouts, and all changes will be synced in real time across devices.

Use Vue’s powerful reactivity system to update the UI whenever the workouts data changes. You can bind the data to your templates and use the built-in directives, such as v-for and v-model, to render and update the workouts.

Additionally, you can use Supabase’s real-time subscriptions to listen for changes in the workouts data. This allows you to instantly update the UI when a new workout is added or an existing workout is modified or deleted.

Conclusion

Vue 3 and Supabase provide a powerful combination for building a workout tracker app. With Vue’s reactivity and Supabase’s real-time database, you can create a seamless and scalable user experience. Whether you are tracking your own workouts or building a fitness app for others, Vue 3 and Supabase are powerful tools to have in your arsenal.
