gotrue-js library
This is a JavaScript client library for the GoTrue API.
It lets you create and authenticate users and is a building block for constructing the UI for signups, password recovery, login and logout.
Play around the methods via the demo site.
Installation
yarn add gotrue-js
Usage
import GoTrue from 'gotrue-js';
// Instantiate the GoTrue auth client with an optional configuration
auth = new GoTrue({
APIUrl: 'https://<your domain name>/.netlify/identity',
audience: '',
setCookie: false,
});
GoTrue configuration
APIUrl: The absolute path of the GoTrue endpoint. To find the APIUrl
, go to Identity
page of your Netlify site dashboard.
audience(optional): audience
is one of the pre-defined JWT payload claims. It's an optional attribute which is set to be empty by default. If you were hosting your own identity service and wanted to support multitenancy, you would need audience
to separate the users.
setCookie(optional): set to be false
by default. If you wish to implement the remember me
functionality, set the value to be true
.
Error handling
If an error occurs during the request, the promise may be rejected with an Error, HTTPError
, TextHTTPError
, or JSONHTTPError
. See micro-api-client-lib error types.
Authentication examples
Create a new user
Create a new user with the specified email and password
auth.signup(email, password);
Example usage:
auth
.signup(email, password)
.then((response) => console.log('Confirmation email sent', response))
.catch((error) => console.log("It's an error", error));
Example response object:
{
"id": "example-id",
"aud": "",
"role": "",
"email": "example@example.com",
"confirmation_sent_at": "2018-04-27T22:36:59.636416916Z",
"app_metadata": { "provider": "email" },
"user_metadata": null,
"created_at": "2018-04-27T22:36:59.632133283Z",
"updated_at": "2018-04-27T22:37:00.061039863Z"
}
Also, make sure the Registration preferences
under Identity settings
in your Netlify dashboard are set to Open
.
If the registration preferences is set to be Invite only
, you'll get an error message like this:
{code: 403, msg: 'Signups not allowed for this instance'}
Confirm a new user signup
This function confirms a user sign up via a unique confirmation token
auth.confirm(token, remember);
When a new user signed up, a confirmation email will be sent to the user if Autoconfirm
isn't turned on under the identity settings.
In the email, there's a link that says "Confirm your email address".
When a user clicks on the link, it'll be redirected to the site with a fragment identifier #confirmation_token=Iyo9xHvsGVbW-9A9v4sDmQ
in the URL.
For all good reasons, the confirmation_token
is hidden from the browser via a redirect.
If you wish to manually confirm a user using the auth.confirm(token, remember)
method,
you can copy the link location of the email and use the curl -I
script to get the confirmation_token
from your terminal. E.g.,
$ curl -I https://mandrillapp.com/track/click/30002868/example.netlify.com?p=example-token

Request password recover email
This function sends a request to GoTrue API and triggers a password recovery email to the specified email address.
Similar to confirmation_token
, the recovery_token
is baked in the link of the email. You can also copy the link location from the email and run curl -I
in the command line to grab the token.
auth.requestPasswordRecovery(email)
Example usage:

Update a user
This function updates a user object with specified attributes
user.update(attributes)
Users can update their user_metadata
field. To do this, pass an object to the attributes.data
key with the fields you want to update. Updates to a users app_metadata
must be performed from a secure environment, such as a Lambda function. For examples on updating user and app metadata, see netlify/identity-update-user-data.
Example usage:
const user = auth.currentUser();
user
.update({ email: 'example@example.com', password: 'password' })
.then((user) => console.log('Updated user %s', user))

}
Get a JWT token

const jwt = user.jwt();
jwt
.then((response) => console.log('This is a JWT token', response))
.catch((error) => {
console.log('Error fetching JWT token', error);
throw error;

Logout a user
This function removes the current session of the user and log out the user
user.logout()
Example usage:
const user = auth.currentUser();
user
.logout()
.then(response => console.log("User logged out");)
.catch(error => {
console.log("Failed to logout user: %o", error);
throw error;
});
Admin methods
The following admin methods are currently not available to be used directly. You can access context.clientContext.identity
and get a short lived admin token through a Lambda function and achieve the same goals, e.g., update user role, create or delete user etc. See Functions and Identity for more info.
For users of Netlify CLI - functions using admin methods will not work locally - they need to be deployed to your site in order to work as intended.
Let's create a simple login form in HTML and JavaScript to interact with a lambda function and test out the admin methods.
- Create an HTML form for user login
<h2>Log in</h2>
<form name="login">
<div class="message"></div>
<p>
<label>Email<br /><input type="email" name="email" required /></label>
</p>
<p>
<label>Password<br /><input type="password" name="password" required /></label>
</p>
<button type="submit">Log in</button>
</form>
- Invoke lambda function. (In this example our function is names as
hello.js
)
document.querySelector("form[name='login']").addEventListener("submit", e => {
e.preventDefault();
const form = e.target;
const { email, password } = form.elements;
auth
.login(email.value, password.value, true)
.then(response => {
const myAuthHeader = "Bearer " + response.token.access_token; //creates the bearer token
fetch("/.netlify/functions/hello", {
headers: { Authorization: myAuthHeader },
credentials: "include"
})
.then(response => {
console.log({ response });
})
.catch(error => {...});
})
.catch(error => {...});
});
Get a user
This function retrieves a user object with the specified user id
getUser(user) {
return this.user.\_request(`/admin/users/${user.id}`);
}
Example usage:
import fetch from 'node-fetch';
exports.handler = async (event, context) => {
const { identity, user } = context.clientContext;
const userID = user.sub;
const userUrl = `${identity.url}/admin/users/{${userID}}`;
const adminAuthHeader = `Bearer ${ identity.token}`;
try {
return fetch(userUrl, {
method: 'GET',
headers: { Authorization: adminAuthHeader },
})
.then((response) => response.json())
.then((data) => {
console.log('data', JSON.stringify(data));
return { statusCode: 204 };
})
.catch((error) => {
console.log('Failed to get user! 500! Internal.');
return {
statusCode: 500,
body: `Internal Server Error: ${ error}`,
};
});
} catch (error) {
console.log('GOT HERE! 500! outer');
return { statusCode: 500, body: `Internal Server Error: ${ error}` };
}
};
Example response object:
{
"id": "example-id",
"aud": "",
"role": "",
"email": "example@netlify.com",

import fetch from "node-fetch";
exports.handler = async (event, context) => {

Oauth providers supported by Netlify
Currently we support Google, GitHub, GitLab, and BitBucket as directly supported in the Netlify app UI (other oauth providers require serverless functions to be set up correctly, but these don't.)
acceptInviteExternalUrl
and loginExternalUrl
are useful for that. You can see example usage in netlify-identity-widget
