@robinbobin/react-native-google-drive-api-wrapper v2.2.3
This wrapper facilitates the use of the Google Drive API v3.
It doesn't provide any authorization mechanism, so another package has to be used. I use @react-native-google-signin/google-signin (thanks for the great work, vonovak!).
If something doesn't work as expected, please do have a look at an example project before opening an issue.

Installation
npm i @robinbobin/react-native-google-drive-api-wrapperUsage
Examples:
// General setup
import { GoogleSignin } from '@react-native-google-signin/google-signin'
import { INFINITE_TIMEOUT, GDrive } from '@robinbobin/react-native-google-drive-api-wrapper'
...
// Somewhere in your code
GoogleSignin.configure(...)
await GoogleSignin.signIn()
const gdrive = new GDrive()
gdrive.accessToken = (await GoogleSignin.getTokens()).accessToken
// fetch() invocations wait infinitely
// gdrive.fetchTimeout = INFINITE_TIMEOUT// List files
await gdrive.files.list(...)// List files in `appDataFolder`
import { APP_DATA_FOLDER_ID } from '@robinbobin/react-native-google-drive-api-wrapper'
...
await gdrive.files.list({ ..., spaces: APP_DATA_FOLDER_ID })// Create a binary file and read it
import { MIME_TYPES } from '@robinbobin/react-native-google-drive-api-wrapper'
...
const file = await gdrive.files.newMultipartUploader()
.setData([1, 2, 3, 4, 5])
.setDataMimeType(MIME_TYPES.application.octetStream)
.setRequestBody({ name: "multipart_bin" })
.execute()
console.log(await gdrive.files.getBinary(file.id))API
Notes:
STANDARD_PARAMETERS_FIELDS_ALLcan be used instead of*as a value forfieldsinqueryParametersof all methods:import { STANDARD_PARAMETERS_FIELDS_ALL } from '@robinbobin/react-native-google-drive-api-wrapper' ... await gdrive.about.get(STANDARD_PARAMETERS_FIELDS_ALL)Query parameters of certain methods have string properties containing a comma-separated list of some values (e.g.
spacesinlist). This wrapper acceptsstringandstring[]values for these properties.stringvalues are passed as-is, andstring[]values are converted to comma-separated lists.
