Build a User Management App with SolidJS

This tutorial demonstrates how to build a basic user management app. The app authenticates and identifies the user, stores their profile information in the database, and allows the user to log in, update their profile details, and upload a profile photo. The app uses:

Supabase Database - a Postgres database for storing your user data and Row Level Security so data is protected and users can only access their own information.
Supabase Auth - users log in through magic links sent to their email (without having to set up passwords).
Supabase Storage - users can upload a profile photo.

Supabase User Management example

If you get stuck while working through this guide, refer to the full example on GitHub.

Project setup

Before we start building we're going to set up our Database and API. This is as simple as starting a new Project in Supabase and then creating a "schema" inside the database.

Create a project

Create a new project in the Supabase Dashboard.
Enter your project details.
Wait for the new database to launch.

Set up the database schema

Now we are going to set up the database schema. We can use the "User Management Starter" quickstart in the SQL Editor, or you can just copy/paste the SQL from below and run it yourself.

Go to the SQL Editor page in the Dashboard.
Click User Management Starter.
Click Run.

You can easily pull the database schema down to your local project by running the db pull command. Read the local development docs for detailed instructions.


_10supabase link --project-ref <project-id>
_10# You can get <project-id> from your project's dashboard URL: https://supabase.com/dashboard/project/<project-id>
_10supabase db pull

Get the API Keys

Now that you've created some database tables, you are ready to insert data using the auto-generated API. We just need to get the Project URL and anon key from the API settings.

Go to the API Settings page in the Dashboard.
Find your Project URL, anon, and service_role keys on this page.

Building the app

Let's start building the SolidJS app from scratch.

Initialize a SolidJS app

We can use Degit to initialize an app called supabase-solid:


_10npx degit solidjs/templates/ts supabase-solid
_10cd supabase-solid

Then let's install the only additional dependency: supabase-js


_10npm install @supabase/supabase-js

And finally we want to save the environment variables in a .env. All we need are the API URL and the anon key that you copied earlier.

.env


_10VITE_SUPABASE_URL=YOUR_SUPABASE_URL
_10VITE_SUPABASE_ANON_KEY=YOUR_SUPABASE_ANON_KEY

Now that we have the API credentials in place, let's create a helper file to initialize the Supabase client. These variables will be exposed on the browser, and that's completely fine since we have Row Level Security enabled on our Database.

src/supabaseClient.jsx


_10import { createClient } from '@supabase/supabase-js'
_10
_10const supabaseUrl = import.meta.env.VITE_SUPABASE_URL
_10const supabaseAnonKey = import.meta.env.VITE_SUPABASE_ANON_KEY
_10
_10export const supabase = createClient(supabaseUrl, supabaseAnonKey)

App styling (optional)

An optional step is to update the CSS file src/index.css to make the app look nice. You can find the full contents of this file here.

Let's set up a SolidJS component to manage logins and sign ups. We'll use Magic Links, so users can sign in with their email without using passwords.

src/Auth.tsx


_51import { createSignal } from 'solid-js'
_51import { supabase } from './supabaseClient'
_51
_51export default function Auth() {
_51  const [loading, setLoading] = createSignal(false)
_51  const [email, setEmail] = createSignal('')
_51
_51  const handleLogin = async (e: SubmitEvent) => {
_51    e.preventDefault()
_51
_51    try {
_51      setLoading(true)
_51      const { error } = await supabase.auth.signInWithOtp({ email: email() })
_51      if (error) throw error
_51      alert('Check your email for the login link!')
_51    } catch (error) {
_51      if (error instanceof Error) {
_51        alert(error.message)
_51      }
_51    } finally {
_51      setLoading(false)
_51    }
_51  }
_51
_51  return (
_51    <div class="row flex-center flex">
_51      <div class="col-6 form-widget" aria-live="polite">
_51        <h1 class="header">Supabase + SolidJS</h1>
_51        <p class="description">Sign in via magic link with your email below</p>
_51        <form class="form-widget" onSubmit={handleLogin}>
_51          <div>
_51            <label for="email">Email</label>
_51            <input
_51              id="email"
_51              class="inputField"
_51              type="email"
_51              placeholder="Your email"
_51              value={email()}
_51              onChange={(e) => setEmail(e.currentTarget.value)}
_51            />
_51          </div>
_51          <div>
_51            <button type="submit" class="button block" aria-live="polite">
_51              {loading() ? <span>Loading</span> : <span>Send magic link</span>}
_51            </button>
_51          </div>
_51        </form>
_51      </div>
_51    </div>
_51  )
_51}

Account page

After a user is signed in we can allow them to edit their profile details and manage their account.

Let's create a new component for that called Account.tsx.

src/Account.tsx


_112import { AuthSession } from '@supabase/supabase-js'
_112import { Component, createEffect, createSignal } from 'solid-js'
_112import { supabase } from './supabaseClient'
_112
_112interface Props {
_112  session: AuthSession
_112}
_112
_112const Account: Component<Props> = ({ session }) => {
_112  const [loading, setLoading] = createSignal(true)
_112  const [username, setUsername] = createSignal<string | null>(null)
_112  const [website, setWebsite] = createSignal<string | null>(null)
_112  const [avatarUrl, setAvatarUrl] = createSignal<string | null>(null)
_112
_112  createEffect(() => {
_112    getProfile()
_112  })
_112
_112  const getProfile = async () => {
_112    try {
_112      setLoading(true)
_112      const { user } = session
_112
_112      const { data, error, status } = await supabase
_112        .from('profiles')
_112        .select(`username, website, avatar_url`)
_112        .eq('id', user.id)
_112        .single()
_112
_112      if (error && status !== 406) {
_112        throw error
_112      }
_112
_112      if (data) {
_112        setUsername(data.username)
_112        setWebsite(data.website)
_112        setAvatarUrl(data.avatar_url)
_112      }
_112    } catch (error) {
_112      if (error instanceof Error) {
_112        alert(error.message)
_112      }
_112    } finally {
_112      setLoading(false)
_112    }
_112  }
_112
_112  const updateProfile = async (e: Event) => {
_112    e.preventDefault()
_112
_112    try {
_112      setLoading(true)
_112      const { user } = session
_112
_112      const updates = {
_112        id: user.id,
_112        username: username(),
_112        website: website(),
_112        avatar_url: avatarUrl(),
_112        updated_at: new Date().toISOString(),
_112      }
_112
_112      const { error } = await supabase.from('profiles').upsert(updates)
_112
_112      if (error) {
_112        throw error
_112      }
_112    } catch (error) {
_112      if (error instanceof Error) {
_112        alert(error.message)
_112      }
_112    } finally {
_112      setLoading(false)
_112    }
_112  }
_112
_112  return (
_112    <div aria-live="polite">
_112      <form onSubmit={updateProfile} class="form-widget">
_112        <div>Email: {session.user.email}</div>
_112        <div>
_112          <label for="username">Name</label>
_112          <input
_112            id="username"
_112            type="text"
_112            value={username() || ''}
_112            onChange={(e) => setUsername(e.currentTarget.value)}
_112          />
_112        </div>
_112        <div>
_112          <label for="website">Website</label>
_112          <input
_112            id="website"
_112            type="text"
_112            value={website() || ''}
_112            onChange={(e) => setWebsite(e.currentTarget.value)}
_112          />
_112        </div>
_112        <div>
_112          <button type="submit" class="button primary block" disabled={loading()}>
_112            {loading() ? 'Saving ...' : 'Update profile'}
_112          </button>
_112        </div>
_112        <button type="button" class="button block" onClick={() => supabase.auth.signOut()}>
_112          Sign Out
_112        </button>
_112      </form>
_112    </div>
_112  )
_112}
_112
_112export default Account

Launch!

Now that we have all the components in place, let's update App.tsx:

src/App.tsx


_27import { Component, createEffect, createSignal } from 'solid-js'
_27import { supabase } from './supabaseClient'
_27import { AuthSession } from '@supabase/supabase-js'
_27import Account from './Account'
_27import Auth from './Auth'
_27
_27const App: Component = () => {
_27  const [session, setSession] = createSignal<AuthSession | null>(null)
_27
_27  createEffect(() => {
_27    supabase.auth.getSession().then(({ data: { session } }) => {
_27      setSession(session)
_27    })
_27
_27    supabase.auth.onAuthStateChange((_event, session) => {
_27      setSession(session)
_27    })
_27  })
_27
_27  return (
_27    <div class="container" style={{ padding: '50px 0 100px 0' }}>
_27      {!session() ? <Auth /> : <Account session={session()!} />}
_27    </div>
_27  )
_27}
_27
_27export default App

Once that's done, run this in a terminal window:


_10npm start

And then open the browser to localhost:3000 and you should see the completed app.

Supabase SolidJS

Bonus: Profile photos

Every Supabase project is configured with Storage for managing large files like photos and videos.

Let's create an avatar for the user so that they can upload a profile photo. We can start by creating a new component:

src/Avatar.tsx


_96import { Component, createEffect, createSignal, JSX } from 'solid-js'
_96import { supabase } from './supabaseClient'
_96
_96interface Props {
_96  size: number
_96  url: string | null
_96  onUpload: (event: Event, filePath: string) => void
_96}
_96
_96const Avatar: Component<Props> = (props) => {
_96  const [avatarUrl, setAvatarUrl] = createSignal<string | null>(null)
_96  const [uploading, setUploading] = createSignal(false)
_96
_96  createEffect(() => {
_96    if (props.url) downloadImage(props.url)
_96  })
_96
_96  const downloadImage = async (path: string) => {
_96    try {
_96      const { data, error } = await supabase.storage.from('avatars').download(path)
_96      if (error) {
_96        throw error
_96      }
_96      const url = URL.createObjectURL(data)
_96      setAvatarUrl(url)
_96    } catch (error) {
_96      if (error instanceof Error) {
_96        console.log('Error downloading image: ', error.message)
_96      }
_96    }
_96  }
_96
_96  const uploadAvatar: JSX.EventHandler<HTMLInputElement, Event> = async (event) => {
_96    try {
_96      setUploading(true)
_96
_96      const target = event.currentTarget
_96      if (!target?.files || target.files.length === 0) {
_96        throw new Error('You must select an image to upload.')
_96      }
_96
_96      const file = target.files[0]
_96      const fileExt = file.name.split('.').pop()
_96      const fileName = `${Math.random()}.${fileExt}`
_96      const filePath = `${fileName}`
_96
_96      const { error: uploadError } = await supabase.storage.from('avatars').upload(filePath, file)
_96
_96      if (uploadError) {
_96        throw uploadError
_96      }
_96
_96      props.onUpload(event, filePath)
_96    } catch (error) {
_96      if (error instanceof Error) {
_96        alert(error.message)
_96      }
_96    } finally {
_96      setUploading(false)
_96    }
_96  }
_96
_96  return (
_96    <div style={{ width: props.size }} aria-live="polite">
_96      {avatarUrl() ? (
_96        <img
_96          src={avatarUrl()!}
_96          alt={avatarUrl() ? 'Avatar' : 'No image'}
_96          class="avatar image"
_96          style={{ height: `${props.size}px`, width: `${props.size}px` }}
_96        />
_96      ) : (
_96        <div
_96          class="avatar no-image"
_96          style={{ height: `${props.size}px`, width: `${props.size}px` }}
_96        />
_96      )}
_96      <div style={{ width: `${props.size}px` }}>
_96        <label class="button primary block" for="single">
_96          {uploading() ? 'Uploading ...' : 'Upload avatar'}
_96        </label>
_96        <span style="display:none">
_96          <input
_96            type="file"
_96            id="single"
_96            accept="image/*"
_96            onChange={uploadAvatar}
_96            disabled={uploading()}
_96          />
_96        </span>
_96      </div>
_96    </div>
_96  )
_96}
_96
_96export default Avatar

And then we can add the widget to the Account page:

src/Account.tsx


_19// Import the new component
_19import Avatar from './Avatar'
_19
_19// ...
_19
_19return (
_19  <form onSubmit={updateProfile} class="form-widget">
_19    {/* Add to the body */}
_19    <Avatar
_19      url={avatarUrl()}
_19      size={150}
_19      onUpload={(e: Event, url: string) => {
_19        setAvatarUrl(url)
_19        updateProfile(e)
_19      }}
_19    />
_19    {/* ... */}
_19  </div>
_19)

At this stage you have a fully functional application!
