Mar 28, I wanted to build an application with login and sign up feature, I ended up with some of the tutorials which use Redux for state management. Since I had no prior experience of using Redux, it became quite a task for me.
So I decided to ditch Redux and use local state of react-native for this example and now. But yes, implementing Redux is bit lengthy. For any small need in Redux, you need to touch store, reducers.
It depends on you, whether you want to do it Redux way or local state. But local state is definitely easier. It provides feature to manage the roles assigned to each user, which can be implemented as giving write access or some other permissions based on his role. Just follow the following steps and you will have a free cluster with some very cool APIs:.
Login: Enter the following command and it will open a browser for you, where you can login with various platforms too:.
Just use any social login such as Google or GitHub to login. Then Click on Allow button, to allow hasura to manage your cluster information. Now return to the terminal and execute following commands. You are done, you have successfully created a back end for your project. I am going to use fetch API for making the requests to backend. I will be creating async functions in my class App to get the details:.
Similarly a login process can be written, the code can be generated using the hasura api-console. To do so just run hasura api-console in your terminal, it will open a page as follows, in which you can navigate to Auth section to get appropriate code.
We could include a TextInput value for getting the value of user name and email. Here is the complete code of App.
React Native App with Authentication and User Management in 15 Minutes
For the above code to work you must have a Home. Just compile the code and you have a basic signup. Since this article is already quite lengthy. I would like to stop on this abstract idea, however if you have any queries do respond, I will try to answer them if they are in my reach.

With React Native, everything needs to be built from scratch—from screen navigation and a responsive interface to creating and wiring up a user management backend. This tutorial will walk you through how to use Stormpath to add authentication and user management to your React Native application with ease.
To complete this tutorial, sign up for a forever-free developer account with Stormpath. Stormpath is free to use, and can help your team write a secure, scalable application without worrying about the nitty-gritty details of authentication, authorization, and user security - or managing a backend user database.
Sign up for an account today! If you want to jump ahead, you can grab the source code from GitHub. Start by installing the React Native command line interface CLI using npm and set up a skeleton project. After entering the created directory, install packages with either npm install or yarnwhich is faster and run the project.
This tutorial deploys to Android but iOS will work as well.
To ensure execution works set up Android on your system and have either a device attached or an emulator running. When successful you should see the stock welcome screen. Navigation in React Native is quite an involved affair. If you just need to switch between views you can simply use a single state variable and some callbacks and no esoteric libraries or components. Create two empty components, Login and Secured. Inside the main script index. The secured page is passed a function to logout which switches the view back to the login page.
Similarly the login page is passed a function which switches the view to the secured page. The login component just needs username and password text inputs and a button and perhaps a title to make everything look professional.
Stormpath is an API that helps developers manage users in their applications without needing to create a backend. Click the friendly green button in your email to verify your account. Fill out the form and click the Create button. To use it you need to modify the login component to respond to each request. To fill these variables you need to use the OnChangeText property. For example in the username component:.

Now, we are ready to go by creating a new project by name DemoLogin via Terminal or iTermwhere we are using iTerm throughout in this article. Command Code.
Open Login. In this article we are using our StackTip logo. Now go to index. If it compile successfully you should find something like.
Create new file inside Login folder and name it as LoginForm. Inside View container tag paste the following snippet, which contains properties for Textfield like keyboardType, returnKeyType, placeholder, placeholderTextColor ,onSubmitEditing, secureTextEntry for secure password. For Login button we can use either react-native Button component or TouchableOpacity, we will use TouchableOpacity in this article. Now we will import this Loginform component in Login.
People who are form iOS background will know the pain to handle this use case in Native UITextfield, this can be achieved easily in react native by KeyboardAvoidingView. Cheers we ready with Login module, and can find the source here. I am a self-driven software professional from Bangalore who live with a desire to set new examples, something that can create a unique signature of my own. I am a very friendly, fun loving person.

The simplest way to add Facebook login functionality to your application is to use the LoginButton object from the SDK.
Navigating Between Screens
When using the LoginButtonall of the complexity of creating a login user interface is handled for you. You specify the permissions that your application needs, and the object notifies you about user actions through attribute-bound functions.
To learn more about permissions, see Permissions Overview. Note that to use the LoginButton object, you must import the LoginButton class from the react-native-fbsdk module. To change the publishing permissions, modify the publishPermissions attribute of the LoginButton tag.
For a list of available permissions, see Permissions Reference. When the login has completed, the function you provide for the onLoginFinished attribute is executed. As you can infer from the example, error conditions are passed in the first parameter, and results in the second. A null error state doesn't indicate a successful login. When a login has completed successfully, meaning that the user has a Facebook account and authorizes your application to access it, then the permissions that they have granted the app are exposed via the grantedPermissions property of the result.
After a succesful login, the view of the text of the login button changes to "Log out" to indicate that clicking on it disconnects your app from their Facebook account. The LoginManager class is used to request additional permissions for a session or to provide login functionality using a custom UI. Like LoginButtonthe LoginManager class is loaded from the react-native-fbsdk module.
The example below performs a login with minimal permissions. Docs Tools Support. React Native SDK. Login Manager The LoginManager class is used to request additional permissions for a session or to provide login functionality using a custom UI.

Oct 18, The index. Click any of the below links to jump down to a description of each file along with it's code:. For example to display a success alert message with the text 'Registration Successful' you can call dispatch alertActions. I've wrapped the action methods in an alertActions object at the top of the file so it's easy to see all available actions at a glance and simplifies importing them into other files.
The implementation details for each action creator are placed in the below functions. Contains Redux action creators for actions related to users. Public action creators are exposed via the userActions object at the top of the file and function implementations are located below, I like this structure because you can quickly see all of the actions that are available. Most of the actions for users are async actions that are made up of multiple sub actions, this is because they have to make an http request and wait for the response before completing.
Async actions typically dispatch a request action before performing an async task e. To keep the code tidy I've put sub action creators into nested functions within each async action creator function. Putting the sub action creators into nested functions also allows me to give them standard names like request, success and failure without clashing with other function names because they only exist within the scope of the parent function.
The way it checks if the user is logged in is by checking that there is a user object in local storage. While it's possible to bypass this check by manually adding an object to local storage using browser dev tools, this would only give access to the client side component, it wouldn't give access to any real secure data from the server api because a valid authentication token JWT is required for this. It could be used for any other constants in the project as well, it doesn't have to be only for redux action types.
I decided to put redux action constants into their own files rather than the same files as redux actions to simplify my redux action files and keep them focused on one thing. The alert constants object contains the redux alert action types used to display and clear alerts in the react application. The user constants object contains the redux user action types that can be dispatched in the react application, async actions that perform http requests involve a request followed by a success or error response, so each of these three steps is represented by a redux action.
The helpers folder contains all the bits and pieces that don't fit into other folders but don't justify having a folder of their own.
If the user isn't logged in an empty object is returned. The fake backend is used for running the tutorial example without a server api backend-less. It monkey patches the fetch function to intercept certain api requests and mimic the behaviour of a real api by managing data in browser local storage.
Any requests that aren't intercepted get passed through to the real fetch function. The history is a custom history object used by the React Router, the reason I used a custom history object instead of the built into React Router is to enable redirecting users from outside React components, for example from the user actions after successful login or registration. The redux store helper calls createStore to create the centralized redux state store for the entire react application. SUCCESS action is dispatched, the reducer updates the alert state to an object with type: 'alert-success' and message: action.
The redux authentication reducer manages the state related to login and logout actions, on successful login the current user object and a loggedIn flag are stored in the authentication section of the application state. The redux registration reducer manages the registration section of the application state, as you can see there isn't much to it, on registration request it just sets a registering flag set to true which the RegisterPage uses to show the loading spinner.
On register success or failure it clears the registration state.React Native Tutorial for Beginners - Getting Started
The redux users reducer manages the users section of the application state which is used by the HomePage to display a list of users and enable deleting of users. CRUD operations. Services can also have methods that don't wrap http calls, for example the userService.
I like wrapping http calls and implementation details in a services layer, it provides a clean separation of concerns and simplifies the redux actions and other modules that use the services. The user service encapsulates all backend api calls for performing CRUD operations on user data, as well as logging and out of the example application.
The service methods are exported via the userService object at the top of the file, and the implementation of each method is located in the function declarations below.
