About this Template

This template is designated for React Native applications and its follow a structure and architecture Feature-based.

This template was based on Rocketseat Basic Template by Rocketseat.

Reasons to create this template

• Expedite the development process.

• Help the project get started in an easy way.

• Help anyone who has the doubt "what would be the best structure and architecture for my React Native application 🤔?"

• This template structure and architecture enable scalable application builds for mobile devices.

• src - Directory containing all the application files, a src directory is created so that the application code can be isolated in one directory and easily ported to other projects, if necessary;

  • assets - Directory for saving all file types, related to assets (Ex: images, fonts, etc ...);

    • images - Directory to store all kinds of images;

      • logo.png - A image example;

  • common - Directory to store every file type that is generic, files that are used in more than one feature;

    • components - Directory for storing components that are generic, components that are used in more than one feature;

      • Button.js - File where all Button component logic will be made;

      • index.js - File where the components will be indexed;

    • utils - Directory to store files that contain logics and are not screens or components.

      • regex.js - File that would have the regex logic;

      • index.js - File where the utils will be indexed;

  • config - Directory for saving application configuration files, for example, Reactotron config, Firebase initialization config, etc;

    • reactotron.js - Archive containing the configuration of Reactotron;

  modules - Directory that stores all the features of the app;

  • home - Directory to store all files (screens, components, utils, etc.) related only to home feature;

    • components - Directory to store components related only to home feature;

      • Card.js - File where all Card component logic will be made;

      • index.js - File where the components will be indexed;

    • screens - Directory to store files from screens related only to home feature.

      • HomeScreen.js - File where all HomeScreen screen logic will be made;

    • utils - Directory to store files that contain logics and are not screens or components related only to home feature.

      • convert.js - File that would have the convert logic;

      • index.js - File where the utils will be indexed;

  navigation - Directory to store the file responsible for the application navigation;

  • index.js - File with the application's navigation settings, it creates the Navigator available in the React Navigation library;

  services - Directory to store the file responsible for the application navigation;

  • api.js - File that contains communication with the API;

  themes - Directory to centralize all files related to global stylization;

  • colors.js - File with color constants to be used in the application;

  • fonts.js - File with fonts and typography to be used in the application;

  • images.js - File with the image constants to be used in the application;

  • metrics.js - File with metrics handled for various device types from your PixelRatio;

  • index.js - File where the themes will be indexed;

index.js - File responsible for centralizing the src directory code, in which routes are called just like any other configuration that needs to be executed at application startup, it is like an Entry Point from thesrc directory;

.editorconfig - File for configuring the Plugin Editor Config, which standardizes some settings for the editor in different environments;

.eslintrc.json - ESLint configuration file, in it are inserted the rules and configurations of Linting of the project, such as the configuration of the Resolver for Babel Plugin Root Import and configuration of the global variable __DEV__;

.prettier.json - Prettier configuration file, in it are inserted the rules and configurations;

.prettierignore - Prettier ignore file, in it are inserted the files where we do not want the prettier to act;

babel.config.js - The Babel Plugin Root file is configured to accept absolute imports in the application using the src directory as the root;

dependencies.json - File containing only one object with list of dependencies that should be installed in the application, it is worth remembering that the dependencies that already come by default in the project as react andreact-native need not be in this list, unless you want manage the version of these libs;

devDependencies.json - File containing only one object with list of development dependencies that should be installed in the application, it is worth remembering that development dependencies that already come by default in the project like @ babel / core,eslint, among others, do not need be on this list, unless you want to manage the version of these libs;

index.js - Application root file, also called Entry Point, is the first file called at the time of the build and execution of the application, in it is called the file src / index.js which in turn calls the routes of the application;

jsconfig.json - Javascript configuration file in the Editor, it is responsible for activating the Auto Complete of Javascript codes in the application;

package.json - Unlike common projects, this file has the necessary settings for publishing the Template in NPM, to know more about it see the section below;

Installation

1. To install and use this template the process is very simple, just create a new project using the command:

react-native init AwesomeExample --template nigg

2. After the project you created you can delete the App.js file (running this command in the project root:rm ./App.js) from the root, because the index.js file now points to the folder src.

This will create the project with all dependencies of the template properly installed and linked, just like the configuration files that are copied to the project 😄.

Additional step on Android

In order for the gestures to be enabled in Android, it is a simple step to open the android / app / src / main / java / <project_package> / MainActivity.java file, and start importing the packages as below:

// ...
import com.facebook.react.ReactActivity;
// Added Imports
import com.facebook.react.ReactActivityDelegate;
import com.facebook.react.ReactRootView;
import com.swmansion.gesturehandler.react.RNGestureHandlerEnabledRootView;

Once the import is done we will create a new method, just below getMainComponentName (), where:

public class MainActivity extends ReactActivity {
  @Override
  protected String getMainComponentName() { ... }
  // Added Method
  @Override
  protected ReactActivityDelegate createReactActivityDelegate() {
    return new ReactActivityDelegate(this, getMainComponentName()) {
      @Override
      protected ReactRootView createRootView() {
        return new RNGestureHandlerEnabledRootView(MainActivity.this);
      }
    };
  }
}
