react-modal-login

Login modal component built with React. Besides a traditional sign in and sign up forms you may use
our pre-configured social login buttons. In the current version we offer a support for Facebook and Google.

Since we intend to target the module for developers, we decided to offer bigger customization options.
This requires some functions to be created in a parent component. Don't worry though. We will cover that topic further
in this manual.

- Styles are not embedded into bundle. If you wish to use default styles, import them:
``

js
import ReactModalLogin from "react-modal-login";
import "react-modal-login/dist/react-modal-login.css";

`bash npm install --save react-modal-login`

If you're willing to use social login buttons, you need to configure them first. You may either keep those settings in a separate file or no, it's up to you. For the sake of keeping everything in order, we demonstrate how to use it in social-config.js file

Typical Facebook configuration Go to Facebook developers platform and create an app (or use existing one). Create a Website configuration.

`js const facebook = { appId: "YOUR FB APP ID GOES HERE", cookie: true, xfbml: true, version: "v12.0", scope: "email", return_scopes: false };

export const facebookConfig = facebook;`

Typical Google configuration Go to Google Developer Console and create a project (or use existing one). Create an OAuth 2.0 client ID.

`js const google = { client_id: "YOUR_CLIENT_ID.apps.googleusercontent.com", scope: "profile email" };

export const googleConfig = google;`

Just as I wrote at the upper part of this manual, our component is highly customizable. Thus, some of the methods needed for basic functionality need to be passed down from the parent component. Just like in the example below. If you would like to enjoy a full range of plugin's functionality you need to:

- declare initial state - it is recommended to do this in a constructor function

`js constructor(props) { super(props);

this.state = { showModal: false, loading: false, error: null };

}`

You need to create methods to be passed to ReactModalLogin component such as:

- openModal()- action to open the modal. For instance, you may bind this to click of the "sign in" button etc. -closeModal()- action to close the modal. You need to pass it to the component later on to enable hiding the modal by clicking close button or clicking in overlay wrap -startLoading()- action needed to serve the loading event. When there is an asynchronous action in component you may be willing to make other components inactive -finishLoading()- that action is indicating the end of loading and it's making all the components inside the component active again -afterTabsChange() - callback to clicking tab button. As provided in our example, you may use it to clean the error state

Most Likely you will be in the need of using social login callback actions. Those may execute some code in your app as well as display the fail error:

- onLoginSuccess()- success login callback -onLoginFail()- "login failed" callback. It is recommended to execute setState() function here which changes the error state

`js import React from "react"; import ReactModalLogin from "react-modal-login";

import { facebookConfig, googleConfig } from "social-config";

class Sample extends React.Component { constructor(props) { super(props);

this.state = { showModal: false, loading: false, error: null }; }

openModal() { this.setState({ showModal: true }); }

closeModal() { this.setState({ showModal: false, error: null }); }

onLoginSuccess(method, response) { console.log("logged successfully with " + method); }

onLoginFail(method, response) { console.log("logging failed with " + method); this.setState({ error: response }); }

startLoading() { this.setState({ loading: true }); }

finishLoading() { this.setState({ loading: false }); }

afterTabsChange() { this.setState({ error: null }); }

render() { return (


        
                  visible={this.state.showModal}
          onCloseModal={this.closeModal.bind(this)}
          loading={this.state.loading}
          error={this.state.error}
          tabs={{
            afterChange: this.afterTabsChange.bind(this)
          }}
          loginError={{
            label: "Couldn't sign in, please try again."
          }}
          registerError={{
            label: "Couldn't sign up, please try again."
          }}
          startLoading={this.startLoading.bind(this)}
          finishLoading={this.finishLoading.bind(this)}
          providers={{
            facebook: {
              config: facebookConfig,
              onLoginSuccess: this.onLoginSuccess.bind(this),
              onLoginFail: this.onLoginFail.bind(this),
              label: "Continue with Facebook"
            },
            google: {
              config: googleConfig,
              onLoginSuccess: this.onLoginSuccess.bind(this),
              onLoginFail: this.onLoginFail.bind(this),
              label: "Continue with Google"
            }
          }}
        />


    );
  }
}

- mainWrapClass |_string_| - custom class of the whole component's wrapper (which contains both overlay and the popup itself)

- mainWrapId |_string_| - id of the whole component's wrapper

- initialTab |_string_| - (default _"login"_) initial tab we'd like to mark as opened - _'login'_, _'register'_ or _'recoverPassword'_. Think of it as defaultValue in stateless inputs. It will be renamed to defaultValue in later releases.

- onAfterCloseModal |_function_| - action executing just after the closing of modal

- onBeforeCloseModal |_function_| - action executing just before the closing of modal

- onCloseModal |_function_| - function closing the modal

- overlayClass |_string_| - custom class of the popup wrap overlay

- containerClass|_string_| - close button container custom class -element |_component_| - custom close button we'd like to attach

- aboveSocialsLoginContainer |_component_| - custom container above socials buttons visible on login tab

- aboveSocialsRegisterContainer |_component_| - custom container above socials buttons visible on register tab

- aboveSocialsRecoverPasswordContainer |_component_| - custom container above socials buttons visible on recover password tab

- form |_object_| - object of custom login/register form you may include in popup

- containerClass|_string_| - login error container custom class -label |_string_ or _component_| - text of failed login message

1. Uncaught ReferenceError: FB is not defined or Cannot read property 'auth2' of undefined. This is because this component initializes the Facebook and Google on componentDidUpdate checking whether thevisible prop has changed. If you set visible={true}then the component will not initialize. This happens to prevent initialization of FB and Google login code on page load. To solve this, you can eg.visible={this.state.visible} and set visible state on componentDidMount.

Social buttons API

Both Facebook and Google instances are initialized the first time you open popup modal. We decided to take such an attitude to save some of the precious loading time when the user enters the website.

After the initialization is complete you have an access to:

- Facebook instance - window.FB- Google instance -window.gapi

Playing with demos

If you would like to run demos locally:

`bash git clone https://github.com/thebeaverhead/react-modal-login npm install npm start`

Update demo/es/social_config.jsfile with your credentials. If you won't change them, they should work for your local addresslocalhost:8080.

Open _http://localhost:8080_.

if you're using docker you need to pass -p 8080:8080 parameter to your docker run command.

All the source files of the component are in the _/src_ path.

Demo pages are located in _/demo_ folder. When you type npm startwebpack-dev-server starts watching _/demo/es/index.js_ and then compiles all the dependencies you require inside it (may be _.js, _.less or \*.css) to _/demo/bundle.js_ which is then included in _/demo/index.html_ and served in _http://localhost:8080_.

You may change the port from 8080 to something different in _webpack.dev.config.js_ file.

There is a hot reloader so you don't really need to reload the page manually since all the changes _.js and _.less files cause it to happen automatically.

Testings

To run tests simply type:

`bash npm test`

Production build

To build a production package you need to type:

`bash git clone https://github.com/thebeaverhead/react-modal-login npm install npm run build-prod``

Then all the required _.less and _.js files from _/src_ path are compiled into _/dist_ folder.

By default styles are bundled into _/dist/react-modal-login.js_ but you may change that behaviour in a
_webpack.prod.config.js_ config file and use _/dist/react-modal-login.min.css_ instead.
