Supabase

Introduction

Supabase is an open-source Firebase alternative that provides backend features. This tutorial steps will focus specifically on database and authentication features. We'll see how to use Supabase as a data provider and implement authentication to refine app.

refine offers built-in data provider support for Supabase and handles all required data service methods out-of-the-box. Therefore, we will not need to use complex boilerplate codes to make it work. refine handles all the complex works for us by internal hooks and implementations.

We'll build a simple CRUD app with refine and use Supabase as a data provider. We'll also see how to use Supabase's authentication features on refine app.

We are assuming that you have already know how refine works. If not, please check out the Tutorial section first.

Refer to docs for more information about data provider &#8594

Project Setup

We'll be using create refine-app CLI to bootstrap our example project with a special preset defined to Supabase example

npm create refine-app@latest -- --preset refine-antd-supabase my-supabase-app

Also, we need to install npm packages to use markdown editor:

npm i @uiw/react-md-editor

This will create a new refine app with Supabase data provider and Ant Desing as a UI framework. We'll be using this project as a base to implement our example.

Establishing Supabase connection

Initialize Supabase client

If you head over to src/utilty folder, you'll see a file called supabaseClient.ts created by CLI. This auto-generated file contains API credentials and a function that initializes the Supabase client.

import { createClient } from '@refinedev/supabase'

const SUPABASE_URL = 'https://iwdfzvfqbtokqetmbmbp.supabase.co'
const SUPABASE_KEY =
'eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJyb2xlIjoiYW5vbiIsImlhdCI6MTYzMDU2NzAxMCwiZXhwIjoxOTQ2MTQzMDEwfQ._gr6kXGkQBi9BM9dx5vKaNKYj_DJN1xlkarprGpM_fU'

export const supabaseClient = createClient(SUPABASE_URL, SUPABASE_KEY, {
db: {
schema: 'public',
},
auth: {
persistSession: true,
},
})

We'll use this example API credentials and createClient method that exposes from refine-supabase package for enabling refine to Supabase API connection.

You can find your Supabase URL and key from your Supabase dashboard &#8594

tip

You can also use environment variables to store your Supabase URL and key. This is a good practice to keep your sensitive information safe.

Register Supabase data provider

Let's head over to App.tsx file where all magic happens. This is the entry point of our app. We'll be registering our Supabase data provider here.

App.tsx
import { Refine } from "@refinedev/core";
...
import { dataProvider } from "@refinedev/supabase";
import { supabaseClient } from "utility";

function App() {
return (
<Refine
dataProvider={dataProvider(supabaseClient)}
/* ... */
>
{/* ... */}
</Refine>
);
}

export default App;

Highlighted lines are the ones the CLI generator automatically added to register Supabase data provider. Simply, we are passing supabaseClient to dataProvider method to establish a connection with Supabase API.

With this configuration, refine can now communicate with Supabase API and perform all required data service CRUD methods using data hooks.

Refer to documentation to learn more about how to use data hooks &#8594

Understanding the Auth Provider

Auth provider is a concept that allows us to use any authentication service with refine.

You'll see a file called src/authProvider.ts created by CLI. This auto-generated file contains pre-defined functions using Supabase Auth API methods internally to perform authentication and authorization operations.

So basically, this is where we set complete authentication logic for the app.

Since we preferred refine-supabase as the data provider during the CLI project initialization, all required Supabase authentication methods are already implemented for us. This shows us how easy it is to bootstrap a refine app with CLI

Refer to docs for more information about Auth Provider methods and custom Auth Providers &#8594

Take a look the auto-generated authProvider.ts file

src/authProvider.ts
import { AuthBindings } from '@refinedev/core'

import { supabaseClient } from 'utility'

const authProvider: AuthBindings = {
login: async ({ email, password, providerName }) => {
// sign in with oauth
try {
if (providerName) {
const { data, error } = await supabaseClient.auth.signInWithOAuth({
provider: providerName,
})

if (error) {
return {
success: false,
error,
}
}

if (data?.url) {
return {
success: true,
}
}
}

// sign in with email and password
const { data, error } = await supabaseClient.auth.signInWithPassword({
email,
password,
})

if (error) {
return {
success: false,
error,
}
}

if (data?.user) {
return {
success: true,
}
}
} catch (error: any) {
return {
success: false,
error,
}
}

return {
success: false,
error: {
message: 'Login failed',
name: 'Invalid email or password',
},
}
},
register: async ({ email, password }) => {
try {
const { data, error } = await supabaseClient.auth.signUp({
email,
password,
})

if (error) {
return {
success: false,
error,
}
}

if (data) {
return {
success: true,
}
}
} catch (error: any) {
return {
success: false,
error,
}
}

return {
success: false,
error: {
message: 'Register failed',
name: 'Invalid email or password',
},
}
},
forgotPassword: async ({ email }) => {
try {
const { data, error } = await supabaseClient.auth.resetPasswordForEmail(
email,
{
redirectTo: `${window.location.origin}/update-password`,
},
)

if (error) {
return {
success: false,
error,
}
}

if (data) {
notification.open({
type: 'success',
message: 'Success',
description:
"Please check your email for a link to reset your password. If it doesn't appear within a few minutes, check your spam folder.",
})
return {
success: true,
}
}
} catch (error: any) {
return {
success: false,
error,
}
}

return {
success: false,
error: {
message: 'Forgot password failed',
name: 'Invalid email',
},
}
},
updatePassword: async ({ password }) => {
try {
const { data, error } = await supabaseClient.auth.updateUser({
password,
})

if (error) {
return {
success: false,
error,
}
}

if (data) {
return {
success: true,
redirectTo: '/',
}
}
} catch (error: any) {
return {
success: false,
error,
}
}
return {
success: false,
error: {
message: 'Update password failed',
name: 'Invalid password',
},
}
},
logout: async () => {
const { error } = await supabaseClient.auth.signOut()

if (error) {
return {
success: false,
error,
}
}

return {
success: true,
redirectTo: '/',
}
},
onError: async (error) => {
console.error(error)
return { error }
},
check: async () => {
try {
const { data } = await supabaseClient.auth.getSession()
const { session } = data

if (!session) {
return {
authenticated: false,
error: {
message: 'Check failed',
name: 'Session not found',
},
logout: true,
redirectTo: '/login',
}
}
} catch (error: any) {
return {
authenticated: false,
error: error || {
message: 'Check failed',
name: 'Session not found',
},
logout: true,
redirectTo: '/login',
}
}

return {
authenticated: true,
}
},
getPermissions: async () => {
const user = await supabaseClient.auth.getUser()

if (user) {
return user.data.user?.role
}

return null
},
getUserIdentity: async () => {
const { data } = await supabaseClient.auth.getUser()

if (data?.user) {
return {
...data.user,
name: data.user.email,
}
}

return null
},
}

export default authProvider

tip

Auth provider functions are also consumed by refine authorization hooks. Since this is out of scope of this tutorial, we'll not cover them for now


Auth provider needed to be registered in <Refine> component to activate auth features in our app

App.tsx
import { Refine } from "@refinedev/core";
...
import authProvider from './authProvider';

function App() {
return (
<Refine
authProvider={authProvider}
/* ... */
>
{/* ... */}
</Refine>
);
}

export default App;

Also, we'll see the Auth provider methods in action when using LoginPage in the next sections.

At this point, our refine app is configured to communicate with Supabase API and ready to perform authentication operations using Supabase Auth methods.

If you head over to localhost:3000, you'll see a welcome page.

welcome

Now it's time to add some resources to our app.

Adding CRUD pages

Before diving into Supabase features, we'll add simple CRUD pages to make the app more interactive.

note

Since this post focuses on Supabase implementation, we'll not discuss how to create CRUD pages and how it works. You can refer to Tutorial to learn more about creating CRUD pages.

Adding a List page

Let's add a listing page to show data retrieved from Supabase API in the table. Copy and paste the following code to src/pages/posts folder and name it list.tsx.

Show the List Page code

src/pages/posts/list.tsx
import {
List,
useTable,
EditButton,
ShowButton,
getDefaultSortOrder,
FilterDropdown,
useSelect,
} from '@refinedev/antd'
import { Table, Space, Select } from 'antd'

import { IPost, ICategory } from 'interfaces'

export const PostList: React.FC = () => {
const { tableProps, sorter } = useTable<IPost>({
sorters: {
initial: [
{
field: 'id',
order: 'asc',
},
],
},
meta: {
select: '*, categories(title)',
},
})

const { selectProps } = useSelect<ICategory>({
resource: 'categories',
})

return (
<List>
<Table {...tableProps} rowKey="id">
<Table.Column
key="id"
dataIndex="id"
title="ID"
sorter
defaultSortOrder={getDefaultSortOrder('id', sorter)}
/>
<Table.Column key="title" dataIndex="title" title="Title" sorter />
<Table.Column
key="categoryId"
dataIndex={['categories', 'title']}
title="Category"
defaultSortOrder={getDefaultSortOrder('categories.title', sorter)}
filterDropdown={(props) => (
<FilterDropdown {...props}>
<Select
style={{ minWidth: 200 }}
mode="multiple"
placeholder="Select Category"
{...selectProps}
/>
</FilterDropdown>
)}
/>
<Table.Column<IPost>
title="Actions"
dataIndex="actions"
render={(_, record) => (
<Space>
<EditButton hideText size="small" recordItemId={record.id} />
<ShowButton hideText size="small" recordItemId={record.id} />
</Space>
)}
/>
</Table>
</List>
)
}

Adding a Create page

We'll need a page for creating a new record in Supabase API. Copy and paste following code to src/pages/posts folder and name it create.tsx.

Show the Create Page code

src/pages/posts/create.tsx
import { useState } from 'react'

import { Create, useForm, useSelect } from '@refinedev/antd'
import { Form, Input, Select, Upload } from 'antd'
import { RcFile } from 'antd/lib/upload/interface'

import MDEditor from '@uiw/react-md-editor'

import { IPost, ICategory } from 'interfaces'
import { supabaseClient, normalizeFile } from 'utility'

export const PostCreate: React.FC = () => {
const { formProps, saveButtonProps } = useForm<IPost>()

const { selectProps: categorySelectProps } = useSelect<ICategory>({
resource: 'categories',
})

return (
<Create saveButtonProps={saveButtonProps}>
<Form {...formProps} layout="vertical">
<Form.Item
label="Title"
name="title"
rules={[
{
required: true,
},
]}
>
<Input />
</Form.Item>
<Form.Item
label="Category"
name="categoryId"
rules={[
{
required: true,
},
]}
>
<Select {...categorySelectProps} />
</Form.Item>
<Form.Item
label="Content"
name="content"
rules={[
{
required: true,
},
]}
>
<MDEditor data-color-mode="light" />
</Form.Item>
<Form.Item label="Images">
<Form.Item
name="images"
valuePropName="fileList"
normalize={normalizeFile}
noStyle
>
<Upload.Dragger
name="file"
listType="picture"
multiple
customRequest={async ({ file, onError, onSuccess }) => {
try {
const rcFile = file as RcFile
await supabaseClient.storage
.from('refine')
.upload(`public/${rcFile.name}`, file, {
cacheControl: '3600',
upsert: true,
})

const { data } = await supabaseClient.storage
.from('refine')
.getPublicUrl(`public/${rcFile.name}`)

const xhr = new XMLHttpRequest()
onSuccess && onSuccess({ url: data?.publicUrl }, xhr)
} catch (error) {
onError && onError(new Error('Upload Error'))
}
}}
>
<p className="ant-upload-text">Drag & drop a file in this area</p>
</Upload.Dragger>
</Form.Item>
</Form.Item>
</Form>
</Create>
)
}

Adding an Edit page

We'll need a page for editing a record in Supabase API. Copy and paste following code to src/pages/posts folder and name it edit.tsx.

Show the Edit Page code

src/pages/posts/edit.tsx
import React, { useState } from 'react'

import {
Edit,
ListButton,
RefreshButton,
useForm,
useSelect,
} from '@refinedev/antd'
import { Alert, Button, Form, Input, Select, Upload } from 'antd'
import { RcFile } from 'antd/lib/upload/interface'

import MDEditor from '@uiw/react-md-editor'

import { IPost, ICategory } from 'interfaces'
import { supabaseClient, normalizeFile } from 'utility'

export const PostEdit: React.FC = () => {
const [isDeprecated, setIsDeprecated] = useState(false)
const { formProps, saveButtonProps, queryResult } = useForm<IPost>({
liveMode: 'manual',
onLiveEvent: () => {
setIsDeprecated(true)
},
})

const postData = queryResult?.data?.data
const { selectProps: categorySelectProps } = useSelect<ICategory>({
resource: 'categories',
defaultValue: postData?.categoryId,
})

const handleRefresh = () => {
queryResult?.refetch()
setIsDeprecated(false)
}

return (
<Edit
saveButtonProps={saveButtonProps}
pageHeaderProps={{
extra: (
<>
<ListButton />
<RefreshButton onClick={handleRefresh} />
</>
),
}}
>
{isDeprecated && (
<Alert
message="This post is changed. Reload to see it's latest version."
type="warning"
style={{
marginBottom: 20,
}}
action={
<Button onClick={handleRefresh} size="small" type="ghost">
Refresh
</Button>
}
/>
)}

<Form {...formProps} layout="vertical">
<Form.Item
label="Title"
name="title"
rules={[
{
required: true,
},
]}
>
<Input />
</Form.Item>
<Form.Item
label="Category"
name="categoryId"
rules={[
{
required: true,
},
]}
>
<Select {...categorySelectProps} />
</Form.Item>
<Form.Item
label="Content"
name="content"
rules={[
{
required: true,
},
]}
>
<MDEditor data-color-mode="light" />
</Form.Item>
<Form.Item label="Images">
<Form.Item
name="images"
valuePropName="fileList"
normalize={normalizeFile}
noStyle
>
<Upload.Dragger
name="file"
listType="picture"
multiple
customRequest={async ({ file, onError, onSuccess }) => {
const rcFile = file as RcFile
const fileUrl = `public/${rcFile.name}`

const { error } = await supabaseClient.storage
.from('refine')
.upload(fileUrl, file, {
cacheControl: '3600',
upsert: true,
})

if (error) {
return onError?.(error)
}
const { data, error: urlError } = await supabaseClient.storage
.from('refine')
.getPublicUrl(fileUrl)

if (urlError) {
return onError?.(urlError)
}

onSuccess?.({ url: data?.publicUrl }, new XMLHttpRequest())
}}
>
<p className="ant-upload-text">Drag & drop a file in this area</p>
</Upload.Dragger>
</Form.Item>
</Form.Item>
</Form>
</Edit>
)
}

Adding Interfaces and Normalize file

We need to add interfaces for Post and Create pages to src/interfaces/index.d.ts file.

Show the interface code

src/interfaces/index.d.ts
export interface ICategory {
id: string
title: string
}

export interface IFile {
name: string
percent: number
size: number
status: 'error' | 'success' | 'done' | 'uploading' | 'removed'
type: string
uid: string
url: string
}

export interface IPost {
id: string
title: string
content: string
categoryId: string
images: IFile[]
}

Also, the normalizeFile function needed to be added to the src/utility/normalize.ts file to perform file upload operations specifically for Supabase API.

Show the Normalize file code

src/utility/normalize.ts
import { UploadFile } from 'antd/lib/upload/interface'

interface UploadResponse {
url: string
}
interface EventArgs<T = UploadResponse> {
file: UploadFile<T>
fileList: Array<UploadFile<T>>
}

export const normalizeFile = (event: EventArgs) => {
const { fileList } = event

return fileList.map((item) => {
const { uid, name, type, size, response, percent, status } = item

return {
uid,
name,
url: item.url || response?.url,
type,
size,
percent,
status,
}
})
}

Finally expose those modules at src/pages/posts by adding

src/pages/posts/index.ts
export * from './create'
export * from './edit'
export * from './list'

Adding Resources

One last thing we need to do is to add newly created CRUD pages to the resources property of <Refine> component.

src/App.tsx
import { dataProvider } from '@refinedev/supabase';
import { supabaseClient } from 'utility';

import { BrowserRouter, Routes, Route, Outlet } from "react-router-dom";

import { PostList, PostCreate, PostEdit } from 'pages/posts';

function App() {
return (
<BrowserRouter>
<Refine
...
dataProvider={dataProvider(supabaseClient)}
resources={[
{
name: 'posts',
list: "/posts",
create: "/posts/create",
edit: "/posts/edit/:id",
},
]}
>
<Routes>
<Route path="/posts" element={<PostList />} />
<Route path="/posts/create" element={<PostCreate />} />
<Route path="/posts/edit/:id" element={<PostEdit />} />
</Routes>
</Refine>
</BrowserRouter>
);
}

export default App;

The resources property activates the connection between CRUD pages and Supabase API.

refine automatically matches the Supabase API endpoint with CRUD pages for us. In this way, the pages can interact with data from the API.

  • The name property refers to the name of the table in the Supabase database.

  • The list property registers /posts endpoint to the PostList component.

  • The create property registers /posts/create endpoint to the PostCreate component. Thereby, when you head over to yourdomain.com/posts/create, you will see the PostCreate page you just created.

Refer to resources docs for more information &#8594

Understanding the Login screen

After adding the resources, the app will look like:

login

Normally, refine shows a default login page when authProvider and resources properties are passed to <Refine /> component. However, our login screen is slightly different from the default one.

This premade and ready to use Login screen consist LoginPage and authProvider concepts behind the scenes:

Let's check out the LoginPage property:

src/App.tsx
import { Refine, Authenticated } from '@refinedev/core'
import { AuthPage, RefineThemes, ThemedLayout } from '@refinedev/antd'
import routerProvider, {
NavigateToResource,
CatchAllNavigate,
} from '@refinedev/react-router-v6'

import { BrowserRouter, Routes, Route, Outlet } from 'react-router-dom'

import { ConfigProvider } from 'antd'

import authProvider from './authProvider'

/* ... */

function App() {
return (
<BrowserRouter>
<ConfigProvider theme={RefineThemes.Blue}>
<Refine
/* ... */
routerProvider={routerProvider}
authProvider={authProvider}
>
<Routes>
<Route
element={
<Authenticated fallback={<CatchAllNavigate to="/login" />}>
<ThemedLayout>
<Outlet />
</ThemedLayout>
</Authenticated>
}
>
<Route path="/posts" element={<div>dummy list page</div>} />
</Route>
<Route
element={
<Authenticated fallback={<Outlet />}>
<NavigateToResource />
</Authenticated>
}
>
<Route path="/login" element={<AuthPage />} />
<Route path="/register" element={<AuthPage type="register" />} />
<Route
path="/forgot-password"
element={<AuthPage type="forgotPassword" />}
/>
<Route
path="/update-password"
element={<AuthPage type="updatePassword" />}
/>
</Route>
</Routes>
</Refine>
</ConfigProvider>
</BrowserRouter>
)
}

The AuthPage component returns ready-to-use authentication pages for login, register, update, and forgot password actions.

This is where authProvider comes into play.

Remember the Understanding the Auth Provider section? We mentioned login, register,, forgotPassword, and updatePassword functions that use Supabase Auth API methods internally in the authProvider.ts file. These methods automatically bind to <AuthPage> components by refine to perform authentication operations.


flow


By defining the routes array in the routerProvider property, we can access the <AuthPage> authentication pages by navigating to /register, /forgot-password, and /update-password endpoints.

We'll show how to implement third party logins in the next sections.

Refer to AuthPage docs for more information &#8594

Sign in the app with followings credentials:

We have successfully logged in to the app and ListPage renders table of data at the /post route.

list


Now click on the Create button to create a new post. The app will navigate to the post/create endpoint, and CreatePage will render.

Thanks to refine-supabase data provider, we can now start creating new records for the Supabase Database by just filling the form.

create

Social Logins

We'll show how to add Google Login option to the app.

Social login feature can be activated by setting provider property of the <AuthPage> component.

src/App.tsx
import { AuthPage } from '@refinedev/antd'
import { GoogleOutlined } from '@ant-design/icons'

const MyLoginPage = () => {
return (
<AuthPage
type="login"
providers={[
{
name: 'google',
label: 'Sign in with Google',
icon: <GoogleOutlined style={{ fontSize: 18, lineHeight: 0 }} />,
},
]}
/>
)
}

This will add a new Google login button to the login page. After the user successfully logs in, the app will redirect back to the app.

Enable Google Auth on Supabase

Head over to app.supabase.com and sign in to your Supabase account. Next, go to Authentication -> Settings to configure the Auth providers.

You will find the Google Auth option in the Auth providers section; enable it and set your Google Credentials.

Refer to Supabase docs for more information about Credentials &#8594

supabaseConfig

Here is the result:


socialLogin

Let's recap what we have done so far

So far, we have implemented the followings:

  • We have reviewed Supabase Client and data provider concepts. We've seen benefits of using refine and how it can handle complex setups for us.
  • We have talked about the authProvider concept and how it works with Supabase Auth API. We also see the advantages of refine's built-in authentication support.
  • We have added CRUD pages to make the app interact with Supabase API. We've seen how the resources property works and how it connects the pages with the API.
  • We have seen how the LoginPage property works and how it overrides the default login page with the AuthPage component. We've seen how AuthPage component uses authProvider methods internally.
  • We have seen how authorization handling in refine app by understanding the logic behind of LoginPage property, authProvider, and <AuthPage> component.

refine provides solutions for critical parts of the complete CRUD app requirements. It saves development time and effort by providing ready-to-use components and features.

Supabase Real Time Support

refine has a built-in support for Supabase Real Time. It means that when you create, update, or delete a record, the changes will be reflected in the app in real-time. Required Supabase Real Time setup is already done in the @refinedev/supabase` data provider.

You can check the Supabase Real Time integration in the data provider source code &#8594

We only need to register refine's Supabase Live Provider to the liveProvider property to enable real-time support.

src/App.tsx
import { Refine } from '@refinedev/core'
import { liveProvider } from '@refinedev/supabase'
import { supabaseClient } from 'utility'

/* ... */

function App() {
return (
<Refine
liveProvider={liveProvider(supabaseClient)}
options={{ liveMode: 'auto' }}
/* ... */
>
{/* ... */}
</Refine>
)
}
note

For live features to work automatically, we setted liveMode: "auto" in the options prop.

Refer to Live Provider docs for more information &#8594

caution

With Supabase JS client v2, multiple subscription calls are not supported. Check out the related issue, supabase/realtime#271. Multiple subscriptions needs to be made in a single call, which is not supported by the current version of the @refinedev/supabase data provider. You can check out the related documentation in Supabase Realtime Guides.


Let see how real-time feature works in the app


realTime

tip

refine offers out-of-the-box live provider support:

Using meta to pass values to data provider

The meta property is used to pass additional information that can be read by data provider methods.

We'll show an example of getting relational data from different tables on Supabase API using meta property.

Take a look at the useTable hook in List page we created on the previous sections.

select - Handling one-to-many relationship

We pass a select value in meta object to perform relational database operation in Supabase data provider. The data provider methods are using Supabase select property internally.

In this way, we can get the title data from the categories table and display it on the List page.

For example, for posts -> categories relationship, we can get the title data from the categories table and display it on the List page.

src/pages/posts/list.tsx
const { tableProps, sorter } = useTable<IPost>({
resource: 'posts',
meta: {
select: '*, categories(title)',
},
})

useList, useOne, useMany hooks are using Supabase select property internally. So you can pass parameters to the Supbase select method using meta property.

select - Handling many-to-many relationships

For example, for movies <-> categories_movies <-> categories many-to-many relationship, we can get the categories data of a user using meta property.

src/pages/users/list.tsx
const { tableProps, sorter } = useTable<IUser>({
resource: 'movies',
meta: {
select: '*, categories!inner(name)',
},
})

id

meta id property is used to match the column name of the primary key(in case the column name is different than "id") in your Supabase data table to the column name you have assigned.

refine's useMany hook accepts meta property and uses getMany method of data provider.

useMany({
resource: 'posts',
ids: [1, 2],
})

By default, it searches for posts in the id column of the data table.

With passing id parameter to the meta property, we can change the column name to the post_id that will be searched for the ids.

useMany({
resource: 'posts',
ids: [1, 2],
meta: {
id: 'post_id',
},
})

Now it searches for posts in the post_id column of the data table instead of id column.

Deep Filtering

Deep filtering is filtering on a relation's fields.

It gets the posts where the title of the categories is "Beginning". Also the inner fields of the categories can be reached with dot notation.

const { tableProps, sorter } = useTable({
resource: 'posts',
filters: {
initial: [
{ field: 'categories.title', operator: 'eq', value: 'Beginning' },
],
},
meta: {
select: '*, categories!inner(title)',
},
})
caution

If you filter based on a table from an inner join, you will need to use .select('*, mytable!inner(*)') within Supabase.

Example
