Postgres Views: The Hidden Security Gotcha in Supabase

When building with Supabase, Postgres Views can be a powerful tool for simplifying complex queries. But they come with a critical security consideration that isn't immediately obvious: Views bypass Row Level Security (RLS) by default, potentially exposing sensitive data even when your tables are properly secured.As a reminder: RLS is what allows you to safely query your Supabase database directly from the frontend, without routing through your backend server. But if RLS isn't working on a table, that table is like your phone screen on public transport—anyone who wants to take a glance, can.


The Security Challenge
Even if you've carefully configured RLS policies on your tables, views can create an unintended backdoor because:
By default, views don’t use RLS
Supabase's RLS policies page doesn't show or warn about exposed views (last checked 09.03.2025)
Views don't support RLS in the same way tables do



Testing Your View's Security
Before deploying any view to production, it's crucial to verify that it properly respects your RLS policies. Here's a quick way to test if your view is secure:
⛶// First, sign in as a specific user
// Then try to fetch ALL rows from your view
const { data } = await supabase.from('my_view').select('*')
// If your view respects RLS, you should only see rows this user has permission to access.
// If you see ALL rows, your view is bypassing RLS! ?
console.log("view response" ,data)


Securing Your Views
To protect your data, you have several options:
For Postgres 15+:

⛶CREATE VIEW public.my_view
WITH (security_invoker = true) AS
SELECT * FROM my_table;This applies the RLS of my_table to the view you’re creating.
For older Postgres versions:

Create an internal schema: CREATE SCHEMA internal;

Re-create the sensitive view in the internal schema
Delete the public version of the view



When to Use Views
Views are particularly valuable when you need to:
Simplify complex queries that you use frequently
Add computed columns that can't be generated columns
Create virtual tables that recalculate with each request



Example: Active Subscription Status
I recently built a subscription system and wanted to avoid having to write active_until NOW() in every query where I'd need to check for active subscriptions. Planning ahead, I first considered adding an is_active generated column to the table. But I hit a wall: Postgres doesn't allow volatile functions like now() in generated columns. That's when I turned to views as a solution:
⛶CREATE VIEW public.active_subscriptions
WITH (security_invoker = true) AS
SELECT
*,
(active_until now()) AS is_active
FROM
public.subscriptions;This view has been working perfectly, giving me clean queries while maintaining security through security_invoker.

AI enables real-time pricing adjustments based on market conditions, competitor pricing, and customer behavior. Dynamic pricing strategies help businesses remain competitive and maximize profit margins. Companies can use AI-driven pricing tools to analyze competitor prices, monitor demand fluctuations, and automatically adjust prices to optimize sales.


AI-Driven Content and Marketing
Creating engaging content and marketing campaigns is another area where AI is making a difference. AI-powered tools like ChatGPT can generate product descriptions, blog posts, and social media content tailored to a target audience. Additionally, AI-driven email marketing platforms can segment customers and personalize campaigns based on behavior and interests, increasing engagement and conversion rates.


Fraud Detection and Security
AI is also enhancing security in e-commerce. Machine learning algorithms can detect fraudulent transactions in real-time, preventing chargebacks and unauthorized purchases. AI can identify suspicious patterns, flag high-risk transactions, and implement multi-layer authentication processes to safeguard customer data.


The Future of AI in E-Commerce
As AI technology continues to evolve, the possibilities for e-commerce businesses are expanding. From voice commerce and augmented reality shopping experiences to AI-driven supply chain optimization, the future is filled with opportunities for innovation.One example of a company embracing digital transformation is Topture.com, an online retailer specializing in home goods such as saunas, grills, and massage chairs. By leveraging automation and AI-driven marketing strategies, businesses like Topture are able to create seamless shopping experiences that drive engagement and sales.


Conclusion
AI and automation are no longer optional in e-commerce—they are essential tools for growth and success. Whether it's personalizing customer experiences, optimizing pricing, or enhancing security, AI is revolutionizing the way businesses operate online. As technology advances, companies that embrace AI-driven solutions will have a competitive edge in the ever-evolving digital marketplace.

How to Integrate Vue.js with Existing React or Angular Projects Without Conflicts?

Integrating Vue.js into existing React or Angular projects can offer numerous advantages, from enhancing user interface possibilities to leveraging Vue's reactivity system. This guide will walk you through the process, ensuring a smooth integration without conflicts, while keeping your project SEO-optimized and efficient.


Understanding the Need for Integration
Many development teams find themselves needing to incorporate Vue.js either to leverage specific features or due to team preference and expertise. The good news is, it's entirely feasible to do so without running into conflicts, as long as you adhere to a few best practices.


Key Considerations for Integration

Isolate Framework Scopes: Ensure that Vue.js components do not intrude on the scope of React or Angular components. This might involve using separate root elements for different parts of your application.
State Management Separation: Avoid using a single state management solution for both frameworks. Instead, consider adopting separate state management libraries capable of existing independently, such as Vuex for Vue.js.
CSS Encapsulation: Use CSS Modules or Scoped CSS in Vue.js components to prevent CSS conflicts. This will ensure styles meant for Vue components do not accidentally override those for React or Angular components.
Avoid Global Dependencies: Be cautious with dependencies that might be declared at the global level and could affect both frameworks. Use module bundlers like Webpack to handle this efficiently.



Step-by-Step Guide to Integrate Vue.js



1. Setup Vue.js in Your Project

Add Vue.js to your build system, possibly using a CDN or via npm/yarn for greater control.
Create a separate directory for Vue.js components to clearly demarcate them within your project structure.



2. Initialize Vue Components
For React:
⛶// React component file
import Vue from 'vue';
import YourVueComponent from './path/to/vue/component.vue';

function ReactComponent() {
useEffect(() = {
new Vue({
render: h = h(YourVueComponent),
}).$mount('#vue-root');
}, []);

return div id="vue-root"div;
}For Angular:
⛶// Angular component file
import { Component, AfterViewInit, ElementRef } from '@angular/core';
import Vue from 'vue';
import YourVueComponent from './path/to/vue/component.vue';

@Component({
selector: 'app-angular',
template: ``
})
export class AngularComponent implements AfterViewInit {
constructor(private el: ElementRef) {}

ngAfterViewInit() {
new Vue({
render: h = h(YourVueComponent),
}).$mount(this.el.nativeElement.querySelector('#vue-root'));
}
}


3. Manage Inter-Framework Communication
For communication between Vue and React/Angular components, use event emitters or shared services that bridge the frameworks without direct dependency.


4. Debug and Test

Conduct thorough testing to identify any conflicts, particularly with state management and CSS.
Use browser developer tools to ensure components are rendered as expected and styles are correctly applied.



Exploring Further Integrations
If you're looking to expand your Vue.js expertise beyond integrating with React and Angular, consider the following resources:

What Are the Best Practices for Integrating Vue.js with a Laravel Backend?

Integrating Vue.js with a Laravel backend is a powerful combination for developing dynamic web applications. This article outlines best practices to ensure a seamless and effective integration, helping developers leverage the full potential of both technologies. By adhering to these best practices, you can create scalable, maintainable, and high-performing applications.


1. Set Up Laravel Mix
Laravel Mix is an elegant wrapper around Webpack, providing a clean API for defining Webpack build steps for your Laravel applications. Setting up Laravel Mix simplifies the integration of Vue.js by pre-configuring Webpack to compile your Vue components.


Steps:

Install Laravel Mix by running npm install.

Configure webpack.mix.js to include Vue.js:

mix.js('resources/js/app.js', 'public/js')
.vue()
.sass('resources/sass/app.scss', 'public/css');






2. Efficient Component Structure
Organize your Vue components in a modular fashion. Place your components in the resources/js/components directory and structure them to represent your application's hierarchy.


Best Practices:

Create separate directories for different parts of your application.
Use PascalCase for component filenames.
Keep Vue components focused and only include necessary state and logic.



3. Data Handling with Vuex
Vuex is a state management pattern + library for Vue.js applications. Using Vuex with Laravel helps manage state across components, ensuring a consistent data flow.


Setup:

Install Vuex via NPM: npm install vuex.

Create a store and include modules for different parts of your application:

import Vue from 'vue';
import Vuex from 'vuex';

Vue.use(Vuex);

const store = new Vuex.Store({
state: {
// Define application-level state
},
mutations: {
// Sync state changes
},
actions: {
// Async logic
}
});

export default store;






4. API Interaction via Axios
To handle HTTP requests, use Axios for an elegant, promise-based API. This ensures smooth communication between your Vue frontend and Laravel backend.


Integration:

Install Axios: npm install axios.

Set default Axios configuration in resources/js/bootstrap.js:

import axios from 'axios';

axios.defaults.headers.common['X-Requested-With'] = 'XMLHttpRequest';
window.axios = axios;



Create a Laravel API to handle requests and consume it in your Vue components.



5. Secure Data Passing
Ensure secure data sharing between Laravel and Vue.js using CSRF tokens and sessions. Laravel makes it straightforward to pass critical data securely.
