expo-google-drive-api-wrapper

Fork of the react-native-google-drive-api-wrapper project, removed react-native-fs and added the expo-file-system

This wrapper facilitates the use of the google drive api.

It doesn't provide any authorization mechanism, so another package has to be used. I use react-native-google-signin (thanks for the great work guys!).

GDrive

This is the "entry point" of the wrapper. It contains only static methods and fields.

import GDrive from "expo-google-drive-api-wrapper";

• setAccessToken()

  Sets the access token for use in subsequent calls to the api. Get the token from a package you choose to use.

   GDrive.setAccessToken(accessToken);
  

• init()

  Initializes the wrapper.

   GDrive.init();
  

  or

   const params = {
       files: {
           boundary: String // The boundary string for multipart file uploads. Default: "foo_bar_baz".
       }
   };
   
   GDrive.init(params);
  

• isInitialized()

  Returns true if an access token has been supplied, false otherwise.

   GDrive.isInitialized() ? <some code> : <some other code>;
  

Files

• createFileMultipart()

  Creates a file using multipart upload. Returns the result of fetch(). If contents is a base64 string, set isBase64 to true.

   const contents = "My text file contents";
   // or
   const contents = [10, 20, 30];
   
   GDrive.files.createFileMultipart(
       contents,
       "corresponding mime type", {
           parents: ["root"],
           name: "My file"
       },
       isBase64);
       
  

• delete()

  Deletes the specified file returning the result of fetch().

   GDrive.files.delete(fileId);
  

• get()

  Gets a file's metadata or a text-file's content by ID. By default the metadata is returned. Use download() for binary files. For queryParams see "Optional query parameters" here. If you want the content of a text-file and not its metadata add alt: "media" to queryParams.

   const queryParams = { ... };
   GDrive.files.get(fileId, queryParams);
   
  

• download()

  Downloads the specified text or binary file.

  For downloadFileOptions see the description of downloadFile() here. Please, bear in mind that fromUrl is set automatically and any user supplied value will be overwritten.

  The fileName parameter must be the name of the file with the base64 extension or text

  The meaning of queryParams is the same as in get().

  The function returns the result of RNFS.downloadFile(downloadFileOptions).

   GDrive.files.download(fileId, downloadFileOptions, fileName, queryParams);
  

• export()

  Exports a google document, returning the result of fetch().

   GDrive.files.export(fileId, mimeType);
  

• getId()

  Gets the id of the first file with the specified metadata. The function returns a Promise. It's rejected on failure and resolved to the file id or undefined (if nothing is found) on success.

   GDrive.files.getId(
       name: String, // The name.
       parents: [String], // The parents.
       mimeType: String, // The mime type.
       trashed: Boolean // Whether the file is trashed. Default: false
   );
   
  

• list()

  Lists or searches files returning the result of fetch().

   GDrive.files.list({q: "'root' in parents"});
   
  

• update()

  Updates a file's metadata. returning the result of fetch().

   GDrive.files.update("file_id", {
       removeParents: "o_parent_id",
       addParents: "parent_id",
       resource: {
   	modifiedTime: new Date(Date.now()).toISOString(),
       },
   })
  

• safeCreateFolder()

  Gets the id of the first folder with the specified name and parents, creating the folder if it doesn't exist. The function returns a Promise that is rejected on failure and resolved to the folder id on success.

   GDrive.files.safeCreateFolder({
       name: "My folder",
       parents: ["root"]
   });
  

Permissions

• create()

  Creates a permission for the specified file returning the result of fetch().

   GDrive.permissions.create(
       fileId, {
           emailAddress: '[e-mail]',
           role: "reader",
           type: "anyone"
       }, {
           emailMessage: `I shared a file with you.`,
       });
   
  

• delete()

  Delete a permission returning the result of fetch().

   GDrive.permissions.delete("fileId", "permissionId");
