This is a collection of useful classes for RN projects.

1. Installation.
2. Package contents.
3. Version history.

Install with:

npm i react-native-common-utils 

For RN < 0.60:

react-native link react-native-common-utils 

needs to be executed, if you want to use the native modules defined in my package.

1. ApplicationSession
2. EventHandlingHelper
3. NativeEventEmitterWrapper
4. Native modules
5. StaticUtils

Warning: These native modules are currently implemented only for Android. I'll implement them for iOS once… I hope…

1. ShareData
2. GetPath

Shares arbitrary data.

import { ShareData } from "react-native-common-utils"; 

• deleteTempFiles()

  Invoke to delete the temp files created internally by the module.

   ShareData.deleteTempFiles(); 

• send()

  Shares data returning a Promise.

  If you specify an attachment, one of "base64", "path", "uri" must be specified, otherwise the promise will be rejected with the code "ERROR_NO_SRC_TO_COPY".

  A temp file with the content being sent is created for each attachment. If the directory where a temp file is to be created is unavailable, the promise is rejected with the code "ERROR_NO_TEMP_FILE_DST". If a temp file fails to be created, the promise is rejected with the code "ERROR_TEMP_FILE_CREATE".

  Please, bear in mind that these temp files can't be deleted automatically so consider using ShareData.deleteTempFiles().

   const options = { mime: String, // One of the mime types. Default: "*/*". to: String / [String], // "to" address(es). Default: undefined. cc: String / [String], // "cc" address(es). Default: undefined. bcc: String / [String], // "bcc" address(es). Default: undefined. subject: String, // The email subject. Default: null. text: String, // The body of the email. Default: undefined. html: String, // The body of the email. Can contain html. Default: undefined. attachments: [{ fileName: String, // The name of an attachment, as seen by a recipient of the email. Default: uuid. fileExtension: String, // The extension of an attachment, as seen by a recipient of the email. Default: "". base64: String, // Base64 encoded string with the content of an attachment. Default: undefined. path: String, // Path to a file to send as an attachment. Default: undefined. uri: String, // Uri pointing to a file to send as an attachment. Default: undefined. }], createChooser: Boolean, // Android only. Whether to use Intent.createChooser(). Default: true. chooserTitle: String // Android only. Title for the chooser. Default: null. }; ShareData.send(options); 

Gets the path/uri of the specified file.

import { GetPath } from "react-native-common-utils"; 

• get()

  This function returns a Promise resolving to the path/uri of the specified file. "pathType" must be one of:

  Value	Meaning
  "DB"	The file is a db file.

  The promise is rejected with the code "Invalid path type" if pathType is invalid.

   const options = { pathType: String, // The file path type. This parameter must be specified. fileName: String, // The file name. Default: "". fileExtension: String // The file extension. Default: "". }; GetPath.get(options); 

A collection of different static utility methods extending StaticUtils from simple-common-utils.

import { StaticUtils } from "react-native-common-utils"; 

• spinkitColor()

  Taking an RGBA value, returns a string of the form #rrggbb (as react-native-spinkit recognizes).

   StaticUtils.spinkitColor(10); // #000000 StaticUtils.spinkitColor(0xFF487210); // #ff4872 

• getLocaleId()

  Gets the current locale id.

   StaticUtils.getLocaleId(); // GB
