Ivan Vasilov 69ce915a9e chore: Rename SUPABASE_PUBLISHABLE_OR_ANON_KEY to SUPABASE_PUBLISHABLE_KEY for all blocks (#42652)
This PR renames all `SUPABASE_PUBLISHABLE_OR_ANON_KEY` env vars into
`SUPABASE_PUBLISHABLE_KEY` to make the new API keys default. This is in
coordination with the rest of the docs.

I've also cleaned up the `blocks/vue` package from unused files.

## Summary by CodeRabbit

* **Breaking Changes**
* Public environment variable names renamed from PUBLISHABLE_OR_ANON_KEY
→ PUBLISHABLE_KEY across all framework integrations; update your
environment configs.

* **Documentation**
* All framework guides, .env examples and registry docs updated to use
the new variable names.

* **Chores**
* Cleaned up UI registry/templates: some example Vue registry items and
autogenerated registry artifacts were removed or simplified.

title: Password-based Authentication
description: Password-based authentication block for Vue Single Page Applications
---
<BlockPreview name="password-based-auth/auth/sign-up" />
## Installation
<BlockItem
name="password-based-auth-vue"
description="All needed components for the password based auth flow"
/>
## Folder structure
This block assumes that you have already installed a Supabase client for Vue from the previous step.
<RegistryBlock itemName="password-based-auth-vue" />
## Usage
Once you install the block in your Vue project, you'll get all the necessary components to set up a password-based authentication flow.
### Getting started
After installing the block, you'll have the following environment variables in your `.env.local` file:
```env
VITE_SUPABASE_URL=
VITE_SUPABASE_PUBLISHABLE_KEY=
```
- If you're using supabase.com, you can find these values in the [Connect modal](https://supabase.com/dashboard/project/_?showConnect=true&tab=frameworks&framework=vuejs&using=supabasejs) under App Frameworks or in your project's [API keys](https://supabase.com/dashboard/project/_/settings/api-keys).
- If you're using a local instance of Supabase, you can find these values by running `supabase start` or `supabase status` (if you already have it running).
### Setting up routes and redirect URLs
1. Set the site URL in the [URL Configuration](https://supabase.com/dashboard/project/_/auth/url-configuration) settings in the Supabase Dashboard.
1. Set up the route users will visit to reset or update their password. Go to the [URL Configuration](https://supabase.com/dashboard/project/_/auth/url-configuration) settings and add the `forgot-password` route to the list of Redirect URLs. It should look something like: `http://example.com/auth/forgot-password`.
1. Update the redirect paths in `login.vue` and `update-password.vue` components to point to the logged-in routes in your app. Our examples use `/protected`, but you can set this to whatever fits your app.
1. Add the following code in the authenticated route to redirect to login if the user is unauthenticated.
```vue
<script setup lang="ts">
import { onMounted } from 'vue'
import { createClient } from '@/lib/supabase/client'
onMounted(async () => {
const client = createClient()
const { error } = await client.auth.getUser()
if (error) {
location.href = '/login'
}
})
</script>
<template>
<div>Authenticated page</div>
</template>
```
Additionally, you could utilize the Navigation Guards from `vue-router` explained [here](https://router.vuejs.org/guide/advanced/navigation-guards#Global-Before-Guards).
