Unlocking User Authentication with Supabase and Vue.js
As web applications continue to evolve, user authentication remains a crucial aspect of ensuring security and protecting sensitive information. However, implementing authentication can be a daunting task for many developers. Fortunately, services like Supabase offer a solution to simplify this process.
What is Supabase?
Supabase is an open-source alternative to Firebase, providing a range of features, including user authentication and management. It supports various external auth providers, such as passwords, phone numbers, and identity providers like Google, Twitter, Facebook, and Github.
Setting Up Vue.js
To get started, we’ll use the Vue CLI to scaffold a new project. Install the CLI globally by running the command npm install -g @vue/cli. Then, create a new Vue project by running vue create my-app and selecting the necessary features, including Router and Vuex.
Integrating Supabase
Create a Supabase account and set up a new project. Once created, copy the URL and anonymous public API key from the Settings > API section. Save these credentials in a .env.local file in your project root.
Installing Supabase Client Library
Run the command npm install @supabase/supabase-js to install the Supabase client library. Initialize Supabase by creating a supabase.js file in your src directory and pasting in the necessary code.
Creating Pages and Routes
Create Vue component pages for sign-up, login, and dashboard functionality. Set up routes using Vue Router, including a navigation guard to redirect unauthenticated users to the sign-in route.
Configuring Vuex
Install Vuex and vuex-persistedstate to store data accessible by all components. Configure the Vuex store, defining the default values of our data, including the user state.
Storing Data and Committing Mutations
Use mutations to change the state object in our Vuex store. Define actions to commit mutations, including sign-up, sign-in, and sign-out actions. These actions interact with the Supabase API to authenticate users and update the user state.
Adding Logic to Components
Add logic to the sign-up, sign-in, and dashboard components to make them fully functional. Use the Vuex store to access and update the user state.
Putting it All Together
By following these steps, you’ve successfully implemented user authentication using Supabase and Vue.js. You’ve also learned how to use Vuex and Vue Router in your Vue apps with the new composition API.
