Store/Retrieve Files on Google Drive using React Native App

React Native Store/Retrieve Files on Google Drive

In this post, we will see how to Store/Retrieve Files on Google Drive using React Native App. In this example we will see how to integrate Google Drive to perform following operations in React Native App which will work for Android and iOS both.

  1. Create a directory on Google Drive
  2. Pick and Upload any File on Google Drive
  3. List Files from Google Drive (All Files + Filtered Files)
  4. Delete any File from Google Drive
  5. Download any File from Google Drive

We all know Google Drive is a file storage and synchronisation service developed by Google. Google Drive allows users to store files on their servers, synchronise files across devices, and share files.

If we talk about why people integrate Google Drive with any mobile app? The answer is to store the backup files of the mobile app and to store the data which belongs to the user and only and app does not required it for the analytics or for any other use.

How to Integrate Google Drive with React Native App

Let’s see how to integrate Google Drive.

Google provides a very nice API suite for the integration of Google Drive with any platform. We can simply use these HTTP APIs using fetch to manage Google Drive files but while preparing this example we found react-native-google-drive-api-wrapper, it is very simple to use library which provides all the necessary features as functions (internally it uses the same Google Drive V3 APIs). We are going to use the same for this example.

To access any Google Drive API we will need a token with proper permissions to access the files. We can get this token by providing Google Sign in feature (with permission to access Google Drive) in the app. This library does not provides any authorization mechanism so we will use an external Google Sign In library for the login and once user logged in we can request Google to give us a token to access the drive.

What can you do with Google Drive API?

  • Download files from Google Drive and Upload files to Google Drive
  • Search for files and folders stored in Google Drive. Create complex search queries that return any of the file metadata fields in the Files resource
  • Let users share files, folders and drives to collaborate on content
  • Combine with the Google Picker API to search all files in Google Drive, then return the file name, URL, last modified date, and user
  • Create a dedicated Drive folder to store your application’s data so that the app cannot access all the user’s content stored in Google Drive. See Store application-specific data

Google Drive Example Explained

In this example we are going to create a Google Sign In on the first screen, once user logged in he/she will see home screen with all the options to navigate to different screens to upload, list, delete and download the file. We have create separate screen for each operation so that you can understand what exactly you need to perform that operation.

Now let’s start with the example.

To Make a React Native App

Getting started with React Native will help you to know more about the way you can make a React Native project. We are going to use react-native init to make our React Native App. Assuming that you have node installed, you can use npm to install the react-native-cli command line utility. Open the terminal and go to the workspace and run

npm install -g react-native-cli

Run the following commands to create a new React Native project

react-native init ProjectName

If you want to start a new project with a specific React Native version, you can use the --version argument:

react-native init ProjectName --version X.XX.X
react-native init ProjectName --version react-native@next

This will make a project structure with an index file named App.js in your project directory.

Installation of Dependency

This example needs different dependencies which is mentioned below. Please follow all the steps to run the app successfully. To install the dependency open the terminal and jump into your project

cd ProjectName

1. For this example we need Google Sign In in our App for which you can see Example of Google Sign In in React Native Android and iOS App, once you are done with the Google Sign In you can come back and can continue from next step.

If you are done with the Google Sign In integration, have you noticed scopes?

We need to send authorization token to the Drive API call. While generating this token we define scope to access the user data. When we configure Sign In in our app we define these scopes and which Google will confirms from the user after login. You can add the scopes according to your need, here you can find the list of scopes to add on the basis of different requirements. We have added so many scopes for this example as we are going to use maximum features of Google Drive API.

2. Once you are done with the Google Sign In, You can install following dependency to perform different operations on Google Drive

npm install react-native-google-drive-api-wrapper --save

3. Above dependency needs following dependency for the file download so we also need to install that also

npm install react-native-fs --save

4. Next, we are going to use the document picker to pick the file which we will upload to Google Drive, To use document picker install following dependency

npm install react-native-document-picker --save

5. That is enough to store and retrieve the files from Google Drive but in this example we will also use React navigation as we are going to switch the screens. So install the following react-navigation dependencies also

npm install @react-navigation/native --save

Other supporting libraries for react-navigation

npm install react-native-reanimated react-native-gesture-handler react-native-screens react-native-safe-area-context @react-native-community/masked-view --save
npm install @react-navigation/stack --save

CocoaPods Installation

Now we need to install pods

cd ios && pod install && cd ..

Enable Google Drive API from Google API Console

To use Google Drive API in our App we need to enable it. To enable the Google Drive API Please follow the below steps:

  1. Open Google API Console
  2. Find the project in top header (Firebase project you have create for Google Sign In)
  3. On dashboard you will see “ENABLE APIS AND SERVICES”, click on it
  4. In search bar search for “google drive”, you will see some results, just click on Google Drive API
  5. Please enable it, once you do it we have provided the permission successfully

react_native_google_drive_ios_permission

Android Permission

In this example, we are going to store the downloaded file in the external storage and to do that we have to add permission into the AndroidManifest.xml file. Please add the following permissions in your AndroidMnifest.xml. Go to YourProject -> android -> app -> main -> AndroidMnifest.xml

<uses-permission
  android:name="android.permission.WRITE_EXTERNAL_STORAGE"
/>
PermissionPurpose
WRITE_EXTERNAL_STORAGETo create any file in external storage

File Download Android Permission
For more about the permission, you can see this post.

IOS Permission

For the RNFS to get the path to download the file we need to add following permission in iOS

1. Open the project YourProject -> ios -> YourProject.xcworkspace in XCode. Click on Project from the left sidebar

2. Select info tab which is info.plist

3. Click on the plus button to add following permission key and value which will be visible when permission dialog pops up.

KeyValue
Privacy – File Provider Presence Usage DescriptionApp needs File Provider

Project Directory/File Structure

If everything went well then you are ready to move to the next step.

To start with this example you need to create the following directory/file structure. This will have a src directory with all our code, src directory will have two more directory auth and googleDrivescreens. All these directory will have following files for complete example.

react_native_google_drive_example_structure

You can see

  1. App.js contains main navigation
  2. src/HomeScreen.js for the home screen listing
  3. src/auth/GoogleLoginScreen.js for the Google Sign In
  4. src/googleDrivescreens/GDUploadFileScreen.js to upload files to Google Drive
  5. src/googleDrivescreens/GDFilesListingScreen.js for the listing of Google Drive files
  6. src/googleDrivescreens/GDSingleFileScreen.js to get the content of text files without downloading it into the mobile device
  7. src/googleDrivescreens/GDDeleteFileScreen.js to delete any Google Drive file
  8. src/googleDrivescreens/GDDownloadFileScreen.js to download any Google Drive file into mobile device

Code to Store/Retrieve Files on Google Drive

You can find the complete code below. We request to please visit official library page to understand all the functions which we have used to create this example.

Now open App.js in any code editor and replace the code with the following code.
