- id: create-client
name: Create Client
code: |
```js
import { createClient } from '@supabase/supabase-js'
// Create a single supabase client for interacting with your database
const supabase = createClient('https://xyzcompany.supabase.co', 'public-anon-key')

persistSession: true,
detectSessionInUrl: true,
}
const supabase = createClient('https://xyzcompany.supabase.co', 'public-anon-key', options)
```
description: |
By default the API server points to the `public` schema. You can enable other database schemas within the Dashboard.
Go to `Settings > API > Schema` and add the schema which you want to expose to the API. You also need to grant `USAGE` on your new schema with the grants you desire, such as `SELECT, INSERT, UPDATE, DELETE`.
Note: each client connection can only access a single schema, so the code above can access the `other_schema` schema but cannot access the `public` schema.
- id: custom-fetch-implementation
name: Custom Fetch Implementation
code: |
```js
import { createClient } from '@supabase/supabase-js'
const supabase = createClient('https://xyzcompany.supabase.co', 'public-anon-key', {
fetch: fetch.bind(globalThis),
})
```
description: |
`supabase-js` uses the [`cross-fetch`](https://www.npmjs.com/package/cross-fetch) library to make HTTP requests,
but an alternative `fetch` implementation can be provided as an option.
This is most useful in environments where `cross-fetch` is not compatible (for instance Cloudflare Workers).
- id: sign-up
title: 'signUp()'
$ref: '@supabase/gotrue-js.GoTrueClient.signUp'
notes: |
- By default, the user will need to verify their email address before logging in. If you would like to change this, you can disable "Email Confirmations" by going to Authentication -> Settings on [supabase.com/dashboard](https://supabase.com/dashboard)
- If "Email Confirmations" is turned on, a `user` is returned but `session` will be null
- If "Email Confirmations" is turned off, both a `user` and a `session` will be returned
- When the user confirms their email address, they will be redirected to localhost:3000 by default. To change this, you can go to Authentication -> Settings on [supabase.com/dashboard](https://supabase.com/dashboard)
- If signUp() is called for an existing confirmed user:
- If "Enable email confirmations" is enabled on the "Authentication" -> "Settings" page, an obfuscated / fake user object will be returned.
- If "Enable email confirmations" is disabled, an error with a message "User already registered" will be returned.
- To check if a user already exists, refer to getUser().
examples:
- id: sign-up
name: Sign up.
isSpotlight: true

```js
const { user, session, error } = await supabase.auth.signUp({

You can sign up with OAuth providers using the [`signIn()`](/docs/reference/javascript/v1/auth-signin#sign-in-using-third-party-providers) method.
- id: sign-up-with-phone
name: Sign up with Phone.
description: |
Supabase supports Phone Auth. After a user has verified their number, they can use the [`signIn()`](/docs/reference/javascript/v1/auth-signin#sign-in-using-phone) method.
code: |
```js
const { user, session, error } = await supabase.auth.signUp({
phone: '+13334445555',
password: 'some-password',
})
// After receiving an SMS with One Time Password.
let { session, error } = await supabase.auth.verifyOTP({
phone: '+13334445555',
token: '123456',
})
```
- id: sign-in
title: 'signIn()'
$ref: '@supabase/gotrue-js.GoTrueClient.signIn'
notes: |
- A user can sign up either via email or OAuth.
- If you provide `email` without a `password`, the user will be sent a magic link.
- The magic link's destination URL is determined by the SITE_URL config variable. To change this, you can go to Authentication -> Settings on [supabase.com/dashboard](https://supabase.com/dashboard)
- Specifying a `provider` will open the browser to the relevant login page.
examples:
- id: sign-in-with-email-and-password
name: Sign in with email and password
isSpotlight: true
code: |
```js
const { user, session, error } = await supabase.auth.signIn({
email: 'example@email.com',
password: 'example-password',
})
```
- id: sign-in-with-magic-link
name: Sign in with magic link.
description: If no password is provided, the user will be sent a "magic link" to their email address, which they can click to open your application with a valid session. By default, a given user can only request a Magic Link once every 60 seconds.
code: |
```js
const { user, session, error } = await supabase.auth.signIn({
email: 'example@email.com'
})
```
- id: sign-in-with-third-party-provider
name: Sign in using third-party providers.
description: Supabase supports many different [third-party providers](https://supabase.com/docs/guides/auth#providers).
code: |
```js
const { user, session, error } = await supabase.auth.signIn({
// provider can be 'github', 'google', 'gitlab', and more
provider: 'github'
})
```
- id: sign-in-with-phone-and-password
name: Sign in with phone and password
isSpotlight: false
code: |
```js
const { user, session, error } = await supabase.auth.signIn({
phone: '+13334445555',
password: 'some-password',
})
```
- id: sign-in-using-a-third-party-provider-with-redirect
name: Sign in using a third-party provider with redirect
description: |
Note that the `redirectTo` param is only relevant for OAuth logins, where the login flow is managed by
the Auth server. If you are using email/phone logins you should set up your own redirects (within the email/sms template).
Sometimes you want to control where the user is redirected to after they are logged in. Supabase supports this for
any URL path on your website (the URL must either be on the same domain as your [Site URL](https://supabase.com/dashboard/project/_/auth/url-configuration) or match one of the Redirect URLs).
See [redirect URLs and wildcards](/docs/guides/auth/overview#redirect-urls-and-wildcards) to add additional redirect URLs to your project.
code: |
```js
const { user, session, error } = await supabase.auth.signIn({
provider: 'github'
}, {
redirectTo: 'https://example.com/welcome'
})
```
- id: sign-in-with-scopes
name: Sign in with scopes
description: |
If you need additional data from an OAuth provider, you can include a space-separated list of scopes in your request to get back an OAuth provider token.
You may also need to specify the scopes in the provider's OAuth app settings, depending on the provider.
code: |
```js
const { user, session, error } = await supabase.auth.signIn({
provider: 'github'
}, {
scopes: 'repo gist notifications'
})
const oAuthToken = session.provider_token // use to access provider API
```
- id: sign-in-with-refresh-token
name: Sign in using a refresh token (e.g. in React Native).
description: |
If you are completing a sign up or login in a React Native app you can pass the refresh token obtained from the provider to obtain a session.
code: |
```js
// An example using Expo's `AuthSession`
const redirectUri = AuthSession.makeRedirectUri({ useProxy: false });
const provider = 'google';
AuthSession.startAsync({
authUrl: `https://MYSUPABASEAPP.supabase.co/auth/v1/authorize?provider=${provider}&redirect_to=${redirectUri}`,
returnUrl: redirectUri,
}).then(async (response: any) => {
if (!response) return;
const { user, session, error } = await supabase.auth.signIn({
refreshToken: response.params?.refresh_token,
});
});
```

This method gets the user object from memory.
examples:
- id:
name: Get the logged in user
isSpotlight: true
code: |
```js
const user = supabase.auth.user()
```
- id: auth-update
title: 'update()'
$ref: '@supabase/gotrue-js.GoTrueClient.update'
notes: |
User email: By Default, email updates sends a confirmation link to both the user's current and new email.
To only send a confirmation link to the user's new email, disable **Secure email change** in your project's [email auth provider settings](https://supabase.com/dashboard/project/_/auth/providers).
User metadata: It's generally better to store user data in a table within your public schema (i.e., `public.users`).
Use the `update()` method if you have data which rarely changes or is specific only to the logged in user.
examples:
- id: update-the-email-for-an-authenticated-user
name: Update the email for an authenticated user
description: Sends a "Confirm Email Change" email to the new email address.

notes: |
Sends a password reset request to an email address.
- When the user clicks the reset link in the email they are redirected back to your application.
You can configure the URL that the user is redirected to via the `redirectTo` param.
See [redirect URLs and wildcards](/docs/guides/auth/overview#redirect-urls-and-wildcards) to add additional redirect URLs to your project.
- After the user has been redirected successfully, prompt them for a new password and call `updateUser()`:
```js
const { data, error } = await supabase.auth.update({
password: new_password,
})
```

- If using the Supabase hosted platform `apikey` is technically a reserved keyword, since the API gateway will pluck it out for authentication. [It should be avoided as a column name](https://github.com/supabase/supabase/issues/5465).
examples:
- id: getting-your-data
name: Getting your data
isSpotlight: true
code: |
```js
const { data, error } = await supabase
.from('cities')
.select()
```
- id: selecting-specific-columns
name: Selecting specific columns
description: You can select specific fields from your tables.

code: |
```js
const { data, error } = await supabase
.from('countries')
.select(`
name,
cities (
name
)
`)
```
note: |
What about join tables
If you're in a situation where your tables are **NOT** directly related, but instead are joined by a _join table_,
you can still use the `select()` method to query the related data. The PostgREST engine detects the relationship automatically.
For more details, [follow the link](https://postgrest.org/en/latest/api.html#embedding-through-join-tables).
- id: query-the-same-foreign-table-multiple-times
name: Query the same foreign table multiple times
description: |
Sometimes you will need to query the same foreign table twice.
In this case, you can use the name of the joined column to identify
which join you intend to use. For convenience, you can also give an
alias for each column.
code: |
```js
const { data, error } = await supabase
.from('products')
.select(`
id,
supplier:supplier_id ( name ),
purchaser:purchaser_id ( name )
`)
```
- id: filtering-with-inner-joins
name: Filtering with inner joins
description: |
If you want to filter a table based on a child table's values you can use the `!inner()` function. For example, if you wanted
to select all rows in a `message` table which belong to a user with the `username` "Jane":
code: |
```js
const { data, error } = await supabase
.from('messages')
.select('*, users!inner(*)')
.eq('users.username', 'Jane')
```
- id: querying-with-count-option
name: Querying with count option
description: |
You can get the number of rows by using the count option.
Allowed values for count option are `null`, [exact](https://postgrest.org/en/stable/api.html#exact-count), [planned](https://postgrest.org/en/stable/api.html#planned-count) and [estimated](https://postgrest.org/en/stable/api.html#estimated-count).
code: |
```js
const { data, error, count } = await supabase
.from('cities')
.select('name', { count: 'exact' }) // if you don't want to return any rows, you can use { count: 'exact', head: true }
```
- id: querying-json-data
name: Querying JSON data
description: |
If you have data inside of a JSONB column, you can apply select
and query filters to the data values. Postgres offers a
[number of operators](https://www.postgresql.org/docs/current/functions-json.html)
for querying JSON data. Also see
[PostgREST docs](http://postgrest.org/en/v7.0.0/api.html#json-columns) for more details.
code: |
```js
const { data, error } = await supabase
.from('users')
.select(`
id, name,
address->street
`)
.eq('address->postcode', 90210)
```
- name: Return data as CSV
description: |
By default the data is returned in JSON format, however you can also request for it to be returned as Comma Separated Values.
code: |
```js
const { data, error } = await supabase
.from('users')
.select()
.csv()
```
- name: Aborting requests in-flight
description: |
You can use an [`AbortController`](https://developer.mozilla.org/en-US/docs/Web/API/AbortController) to abort requests. Note that `status` and `statusText` doesn't mean anything for aborted requests, since the request wasn't actually fulfilled.
code: |
```js
const ac = new AbortController()
supabase
.from('very_big_table')
.select()
.abortSignal(ac.signal)
.then(console.log)
ac.abort()
// {
// error: {
// message: 'FetchError: The user aborted a request.',
// details: '',
// hint: '',
// code: ''
// },
// data: null,
// body: null,
// count: null,
// status: 400,
// statusText: 'Bad Request'
// }
```
- id: insert
title: 'Create data: insert()'
$ref: '@supabase/postgrest-js."lib/PostgrestQueryBuilder".PostgrestQueryBuilder.insert'
notes: |
- By default, every time you run `insert()`, the client library will make a `select` to return the full record.
This is convenient, but it can also cause problems if your Policies are not configured to allow the `select` operation.
If you are using Row Level Security and you are encountering problems, try setting the `returning` param to `minimal`.
examples:
- id: create-a-record
name: Create a record
isSpotlight: true
code: |
```js
const { data, error } = await supabase
.from('cities')
.insert([
{ name: 'The Shire', country_id: 554 }

```
- id: bulk-create
name: Bulk create
description: |
When running a bulk create, the operation is handled in a single transaction. If any of the inserts fail, all other operations are
rolled back.
code: |
```js
const { data, error } = await supabase
.from('cities')
.insert([
{ name: 'The Shire', country_id: 554 },
{ name: 'Rohan', country_id: 555 },
])
```
- id: upsert
name: Upsert
description: |
For upsert, if set to true, primary key columns would need to be included
in the data parameter in order for an update to properly happen. Also, primary keys
used must be natural, not surrogate. There are however,
[workarounds](https://github.com/PostgREST/postgrest/issues/1118)
for surrogate primary keys.
code: |
```js
const { data, error } = await supabase
.from('cities')
.insert(
[
{ name: 'The Shire', country_id: 554 },
{ name: 'Rohan', country_id: 555 },
{ name: 'City by the Bay', country_id:840}
],
{ upsert: true })
```
- id: update
title: 'Modify data: update()'
$ref: '@supabase/postgrest-js."lib/PostgrestQueryBuilder".PostgrestQueryBuilder.update'
notes: |
- `update()` should always be combined with [Filters](/docs/reference/javascript/using-filters) to target the item(s) you wish to update.
examples:
- id: updating-your-data
name: Updating your data
isSpotlight: true
code: |
```js
const { data, error } = await supabase

```
- id: updating-json-data
name: Updating JSON data
description: |
Postgres offers a
[number of operators](https://www.postgresql.org/docs/current/functions-json.html)
for working with JSON data. Right now it is only possible to update an entire JSON document,
but we are [working on ideas](https://github.com/PostgREST/postgrest/issues/465) for updating individual keys.
code: |
```js
const { data, error } = await supabase
.from('users')
.update(`
address: {
street: 'Melrose Place',
postcode: 90210
}
`)

```
- id: upsert

$ref: '@supabase/postgrest-js."lib/PostgrestQueryBuilder".PostgrestQueryBuilder.upsert'
notes: |
- Primary keys should be included in the data payload in order for an update to work correctly.
- Primary keys must be natural, not surrogate. There are however, [workarounds](https://github.com/PostgREST/postgrest/issues/1118) for surrogate primary keys.
- If you need to insert new data and update existing data at the same time, use [Postgres triggers](https://github.com/supabase/postgrest-js/issues/173#issuecomment-825124550).
examples:
- id: upsert-your-data
name: Upsert your data

```
- id: delete
title: 'Delete data: delete()'
$ref: '@supabase/postgrest-js."lib/PostgrestQueryBuilder".PostgrestQueryBuilder.delete'
notes: |
- `delete()` should always be combined with [filters](/docs/reference/javascript/using-filters) to target the item(s) you wish to delete.
- If you use `delete()` with filters and you have
[RLS](/docs/learn/auth-deep-dive/auth-row-level-security) enabled, only
rows visible through `SELECT` policies are deleted. Note that by default
no rows are visible, so you need at least one `SELECT`/`ALL` policy that
makes the rows visible.
examples:
- id: delete-records

notes: |
- Realtime is disabled by default for new Projects for better database performance and security. You can turn it on by [managing replication](/docs/guides/database/api#managing-realtime).
- If you want to receive the "previous" data for updates and deletes, you will need to set `REPLICA IDENTITY` to `FULL`, like this: `ALTER TABLE your_table REPLICA IDENTITY FULL;`
examples:

description: You can listen to individual rows using the format `{table}:{col}=eq.{val}` - where `{col}` is the column name, and `{val}` is the value which you want to match.
notes: |
- ``eq`` filter works with all database types as under the hood, it's casting both the filter value and the database value to the correct type and then comparing them.

- id: using-filters
title: Using Filters
description: |
Filters can be used on `select()`, `update()`, and `delete()` queries.
If a Postgres function returns a table response, you can also apply filters.
### Applying Filters
You must apply your filters to the end of your query. For example:
```js
const { data, error } = await supabase
.from('cities')
.select('name, country_id')
.eq('name', 'The Shire') // Correct
const { data, error } = await supabase
.from('cities')
.eq('name', 'The Shire') // Incorrect
.select('name, country_id')
```
### Chaining
Filters can be chained together to produce advanced queries. For example:
```js
const { data, error } = await supabase
.from('cities')
.select('name, country_id')
.gte('population', 1000)
.lt('population', 10000)
```
### Conditional Chaining
Filters can be built up one step at a time and then executed. For example:
```js
const filterByName = null
const filterPopLow = 1000
const filterPopHigh = 10000
let query = supabase
.from('cities')
.select('name, country_id')
if (filterByName) { query = query.eq('name', filterByName) }
if (filterPopLow) { query = query.gte('population', filterPopLow) }
if (filterPopHigh) { query = query.lt('population', filterPopHigh) }
const { data, error } = await query
```
- id: or
title: or()
$ref: '@supabase/postgrest-js."lib/PostgrestFilterBuilder".PostgrestFilterBuilder.or'
notes: |
- `.or()` expects you to use the raw [PostgREST syntax](https://postgrest.org/en/stable/api.html#horizontal-filtering-rows) for the filter names and values.
```js
.or('id.in.(6,7), arraycol.cs.{"a","b"}') // Use Postgres list () for in filter. Array {} for array column and 'cs' for contains.
.or(`id.in.(${arrList}),arraycol.cs.{${arr}}`) // You can insert a javascipt array for list or array on array column.
.or(`id.in.(${arrList}),rangecol.cs.[${arrRange})`) // You can insert a javascipt array for list or range on a range column.

```js
.not('name','eq','Luke')
.not('arraycol','cs','{"a","b"}') // Use Postgres array {} for array column and 'cs' for contains.
.not('rangecol','cs','(1,2]') // Use Postgres range syntax for range column.

- id: web-search
name: Websearch
description: |
Uses PostgreSQL's `websearch_to_tsquery` function.
This function will never raise syntax errors, which makes it possible to use raw user-supplied input for search, and can be used with advanced operators.
- `unquoted text`: text not inside quote marks will be converted to terms separated by & operators, as if processed by plainto_tsquery.
- `"quoted text"`: text inside quote marks will be converted to terms separated by `<->` operators, as if processed by phraseto_tsquery.
- `OR`: the word “or” will be converted to the | operator.
- `-`: a dash will be converted to the ! operator.
code: |
```js
const { data, error } = await supabase
.from('quotes')
.select('catchphrase')
.textSearch('catchphrase', `'fat or cat'`, {
type: 'websearch',
config: 'english'
})

$ref: '@supabase/postgrest-js."lib/PostgrestFilterBuilder".PostgrestFilterBuilder.filter'
notes: |
- `.filter()` expects you to use the raw [PostgREST syntax](https://postgrest.org/en/stable/api.html#horizontal-filtering-rows) for the filter names and values, so it should only be used as an escape hatch in case other filters don't work.
```js
.filter('arraycol','cs','{"a","b"}') // Use Postgres array {} for array column and 'cs' for contains.
.filter('rangecol','cs','(1,2]') // Use Postgres range syntax for range column.
.filter('id','in','(6,7)') // Use Postgres list () for in filter.
.filter('id','in',`(${arr})`) // You can insert a javascript array.
