Javascript Reference v1.0

Upgrade guide

supabase-js v2 focuses on "quality-of-life" improvements for developers and addresses some of the largest pain points in v1. v2 includes type support, a rebuilt Auth library with async methods, improved errors, and more.

No new features will be added to supabase-js v1 , but we'll continuing merging security fixes to v1, with maintenance patches for the next 3 months.

Upgrade the client library

Install the latest version


_10
npm install @supabase/supabase-js@2

Optionally if you are using custom configuration with createClient then follow below:

src/supabaseClient.ts

_10
const supabase = createClient(SUPABASE_URL, SUPABASE_ANON_KEY, {
_10
schema: 'custom',
_10
persistSession: false,
_10
})

Auth methods

The signIn() method has been deprecated in favor of more explicit method signatures to help with type hinting. Previously it was difficult for developers to know what they were missing (e.g., a lot of developers didn't realize they could use passwordless magic links).

Sign in with email and password


_10
const { user, error } = await supabase
_10
.auth
_10
.signIn({ email, password })


_10
const { error } = await supabase
_10
.auth
_10
.signIn({ email })

Sign in with a third-party provider


_10
const { error } = await supabase
_10
.auth
_10
.signIn({ provider })

Sign in with phone


_10
const { error } = await supabase
_10
.auth
_10
.signIn({ phone, password })

Sign in with phone using OTP


_10
const { error } = await supabase
_10
.auth
_10
.api
_10
.sendMobileOTP(phone)

Reset password for email


_10
const { data, error } = await supabase
_10
.auth
_10
.api
_10
.resetPasswordForEmail(email)

Get the user's current session


_10
const session = supabase.auth.session()

Get the logged-in user


_10
const user = supabase.auth.user()

Update user data for a logged-in user


_10
const { user, error } = await supabase
_10
.auth
_10
.update({ attributes })

Use a custom access_token JWT with Supabase


_10
const { user, error } = supabase.auth.setAuth(access_token)

The cookie-related methods like setAuthCookie and getUserByCookie have been removed.

For Next.js you can use the Auth Helpers to help you manage cookies. If you can't use the Auth Helpers, you can use server-side rendering.

Data methods

.insert() / .upsert() / .update() / .delete() don't return rows by default: PR.

Previously, these methods return inserted/updated/deleted rows by default (which caused some confusion), and you can opt to not return it by specifying returning: 'minimal'. Now the default behavior is to not return rows. To return inserted/updated/deleted rows, add a .select() call at the end.

Insert and return data


_10
const { data, error } = await supabase
_10
.from('my_table')
_10
.insert({ new_data })

Update and return data


_10
const { data, error } = await supabase
_10
.from('my_table')
_10
.update({ new_data })
_10
.eq('id', id)

Upsert and return data


_10
const { data, error } = await supabase
_10
.from('my_table')
_10
.upsert({ new_data })

Delete and return data


_10
const { data, error } = await supabase
_10
.from('my_table')
_10
.delete()
_10
.eq('id', id)

Realtime methods

Subscribe


_10
const userListener = supabase
_10
.from('users')
_10
.on('*', (payload) => handleAllEventsPayload(payload.new))
_10
.subscribe()

Unsubscribe


_10
userListener.unsubscribe()
