auth-component

Compose a clean Auth UI with these simple React components.

There is also a matching CanJS Stache version: https://github.com/icanjs/can-auth-component

Example Usage

auth-component is a collection of components. They can be composed based on the auth requirements of your application. The main demo shows how to build the example shown in the image above. To run the demo, start an http-server in the root and open http://localhost:8080. Here's the demo code.

<AuthContainer>
  <Tabs activeTab={route.data.page} routeAttr='page' />
 
  <div className='auth-branding'>
    <SVGInline svg={logo} />
  </div>
 
  <div className='oauth-buttons'>
    <FacebookButton popup='true' />
    <GitHubButton popup='true' />
    <GoogleButton popup='true' />
    <MicrosoftButton popup='true' />
    <TwitterButton popup='true' />
  </div>
 
  <Route data={{page: 'login'}} component={LoginForm} />
  <Route data={{page: 'signup'}} component={SignupForm} />
</AuthContainer>

Quick and Easy Horizontal and Vertical Centering

The <AuthContainer></AuthContainer> component is a set a styles that center a white login container both vertically and horizontally inside its parent element. It has no viewModel logic of its own, so all of the other components will work without it.

import AuthContainer from 'auth-component/auth-container/auth-container';
// In your template.
<AuthContainer>
  Put whatever markup you want inside here.
</AuthContainer>

Local Auth Forms, Ready For Use

A basic Local (username & password) Login and Signup form are included.

import SignupForm from 'auth-component/forms/local-signup/local-signup';
import LoginForm from 'auth-component/forms/local-login/local-login';

Check out the local-login demo and local-signup demo code to see example usage.

The following attributes are available in both forms:

• usernameField {String} Allows you to customize one of the attributes sent to the server. It's set to "email" by default.
• usernamePlaceholder {String} Set the placeholder text for the usernameField. Default is "e-mail address".
• passwordField {String} Allows you to customize an attribute sent to the server. The default is "password".
• passwordPlaceholder {String} Set the placeholder text for the passwordField. Default is "password".
• strategy {String} When using feathers-authentication, setting this attribute will add a strategy attribute to the outgoing data.
• Model {can-connect Model} a can-connect compatible Model to use for submitting the form data.
• service {FeathersJS service} a Feathers service to use for submitting the form data.
• suppressWarnings {Boolean} There are a few warnings that will show up by default. Turn them off by setting suppressWarnings to true. Default false.
• error {String} When the server responds with an error string or an error object containing a message string, it will be set on error and shown in the UI above the form.
• buttonText {String} Set the main action button's label. Default is "Login" or "Signup".
• clearError {Function} Clears the error message.
• onSubmit(data) {Function} is called with the form data when the form is submitted. If a Model or service was provided, it will be used to communicate with the server. If not, handleSubmit must be overwritten with your own logic. It must return a Promise.
• onSuccess(responseData) {Function} is called with the server response data.
• onError(error) {Function} is called with the server response error.

As of version 5.0, both forms are based off of @tannerlinsley/react-form. Check out the React-Form API docs to see additional properties and functions that are available.

These are the custom attributes for the <LoginForm> form:

• onForgot {Function} runs when the user clicks the "Forgot Password" link. There is no default handler for this, so you have to provide your own function.

These are the custom attributes for the <SignupForm> form:

• asyncValidation {Function} A function that returns a promise. If an error string is returned, or an error object with a message string is returned, it will become the validation error for the username/email field.

See the "Running the Demos" section to run the included form demos. Both demos include examples for using a Model, service, or custom function.

Create Custom Forms

As of version 5.0, and as part of the refactor to use react-form, you can easily create your own auth form. The Form element is a wrapper for the react-form component by the same name, but adds asynchronous validation support and automatic server response error handling. The following properties are available on the Form component:

• strategy {String} When using feathers-authentication, setting this attribute will add a strategy attribute to the outgoing data.
• Model {can-connect Model} a can-connect compatible Model to use for submitting the form data.
• service {FeathersJS service} a Feathers service to use for submitting the form data.
• suppressWarnings {Boolean} There are a few warnings that will show up by default. Turn them off by setting suppressWarnings to true. Default false.
• error {String} When the server responds with an error string or an error object containing a message string, it will be set on error and shown in the UI above the form.
• clearError {Function} Clears the error message.
• onSubmit(data) {Function} is called with the form data when the form is submitted. If a Model or service was provided, it will be used to communicate with the server. If not, handleSubmit must be overwritten with your own logic. It must return a Promise.
• onSuccess(responseData) {Function} is called with the server response data.
• onError(error) {Function} is called with the server response error.

Check out the React-Form API docs to see additional properties and functions that are available. Below is an annotated example of how to make a custom form.

import React from 'react';
import Form from '../form/form.js';
import { Text } from 'react-form';
import '../forms.less';
import FormError from '../form-error/form-error';
import AsyncValidator from '../async-validator/async-validator';
 
export default ({
  asyncValidation,
  forgotClicked,
  // Allow all react-form props to pass through
  ...rest
}) => {
  return (
    <Form {...rest}>
      {// You must wrap your custom form in two functions as done here.}
      {({error, clearError}) => {
        return ({values, submitForm}) => {
          return (
            <form onSubmit={submitForm} className='auth-component-form'>
              <FormError error={error} clearError={clearError} />
 
              <Text field='email' placeholder='email' tabIndex='1' />
              <Text field='password' type='password' placeholder='password' tabIndex='1' />
 
              {asyncValidation && <AsyncValidator field='emailError' params={queryParams} validate={asyncValidation} />}
 
              <Text field='myCustomField' placeholder='Custom Snazzy Field' tabIndex='1' />
 
              <div className='forgot-password'>
                <a href='javascript://' onClick={forgotClicked} tabIndex='2'>forgot password</a>
              </div>
 
              <button type='submit' tabIndex='1'>Login</button>
            </form>
          );
        };
      }}
    </Form>
  );
};

Any react-form fields you add will be added to the payload and sent to the server.

Asynchronous Field Validation

The AsyncValidator component allows you to run asynchronous validations against a server. The Form example, above, shows how to use it in a form. To make the validations work, you need to use the validate attribute on a form. We assigned the AsyncValidator a field of emailError. Now we can use the emailError attribute in the validate rules:

<SignupForm 
  Model={DummyModel}
  defaultValues={{email: '', password: '', emailError: ''}}
  validate={({email, password, emailError}) => {
    return {
      email: !email ? 'E-mail address is required' : emailError || null,
      password: !password ? 'Password is required' : null
    };
  }}
  onSuccess={handleSuccess}
  usernameField='username'
  usernamePlaceholder='username'
  asyncValidation={simulatedAsyncValidation} />
 
function simulatedAsyncValidation (query) {
  return new Promise((resolve, reject) => {
    setTimeout(() => {
      if (query.email === '[e-mail]') {
        reject('That email is unavailable');
      } else {
        resolve(true);
      }
    }, 500);
  });
}

Automatic Form Error Handling

The FormError component is simply a div with an error message in it. It is used to show error messages returned from a server. See how it's used in the Form example, above, or in the demos. When used with the Form component, errors shows when returned from the server. They are automatically cleared when the form is submitted.

import FormError from 'auth-component/forms/form-error/form-error';
 
<FormError error={error} clearError={clearError} />

• error {String} The error message to display.
• clearError {Function} a function that can be called to clear the error message.

Beautiful, Scalable Buttons

A Generic button and a bunch of hand-tailored, scalable buttons are included.

Generic Auth Button

The generic button is the base for all of the other buttons. You can use it to make your own auth buttons. Here's how the Facebook button implements the generic button:

import React from 'react';
import AuthButton from '../button.jsx';
import svg from './facebook.svg';
 
export default ({name, url, img, alt, text, popup}) => {
  return (
    <AuthButton name={name || 'Facebook'}
      url={url || '/auth/facebook'}
      popup={popup}
      svg={svg}
      alt={alt}
      text={text}
    />
  );
};

• url is like specifying the href on a link. The default value matches FeathersJS default OAuth URLs like /auth/<providerName>. For example, the Facebook button uses /auth/facebook.
• popup, if truthy, simply opens the url in a centered popup window.
• alt is for alt text, the same as on other HTML elements.
• text allows you to specify some text to the right of the image.
• svg allows you to embed svg directly into the button.
• img is supported in place of svg. The img attribute should the the URL to an image.

Ready-to-use Buttons

A bunch of pre-styled buttons are included. They all extend the generic button.

import Amazon from 'auth-component/buttons/amazon/amazon';
import Dropbox from 'auth-component/buttons/dropbox/dropbox';
import Evernote from 'auth-component/buttons/evernote/evernote';
import Facebook from 'auth-component/buttons/facebook/facebook';
import Github from 'auth-component/buttons/github/github';
import Google from 'auth-component/buttons/google/google';
import LinkedIn from 'auth-component/buttons/linkedin/linkedin';
import Microsoft from 'auth-component/buttons/microsoft/microsoft';
import OpenID from 'auth-component/buttons/openid/openid';
import PayPal from 'auth-component/buttons/paypal/paypal';
import Skype from 'auth-component/buttons/skype/skype';
import Slack from 'auth-component/buttons/slack/slack';
import StackOverflow from 'auth-component/buttons/stackoverflow/stackoverflow';
import Twitter from 'auth-component/buttons/twitter/twitter';
import Yahoo from 'auth-component/buttons/yahoo/yahoo';

You'll generally only ever have to specify the url, text, and popup attributes.

import FacebookButton from 'auth-component/buttons/facebook/facebook';
 
<FacebookButton url='/auth/facebook' popup={true} text='Login with Facebook' />

If you don't specify a text attribute, you'll get a square button with an icon. The button with text from the above code would look like the "Login with Facebook" button in this example:

Tabs

Currently, the only set of tabs uses can-route to change tabs. If the feature is needed, this issue for creating a standalone set of tabs is open and could use a champion.

The main demo shows how to use can-route based tabs together. You first need a basic can-route setup, shown in the below example. Then you can use the <Route /> component from can-route-react to show and hide components.

import React from 'react';
import ReactDOM from 'react-dom';
import route from 'can-route';
import DefineMap from 'can-define/map/map';
import {Route} from 'can-route-react';
 
import AuthContainer from './auth-container/auth-container';
import Tabs from 'auth-component/tabs/can-route';
import SignupForm from 'auth-component/forms/signup/';
import LoginForm from 'auth-component/forms/login/';
 
const RouteMap = DefineMap.extend({
  page: {
    type: 'string'
  }
});
route.data = new RouteMap({});
 
// Create a '/page' route.
route('{page}', {page: 'login'});
route.ready();
 
ReactDOM.render(
  <AuthContainer>
    <Tabs activeTab={route.data.page} routeAttr='page' />
 
    <Route data={{page: 'login'}} component={LoginForm} />
    <Route data={{page: 'signup'}} component={SignupForm} />
  </AuthContainer>,
  document.querySelector('[root=true]')
);
