/react-native-project-version-info

Two basic Python scripts that allows you to parse version names and codes from your React Native project

Primary LanguagePython

react-native-project-version-info

Do you need a way to:

  • Automate a way of fetching your Android version name or version code?
  • Automate a way to get the iOS Version or Build number?
  • Only need this information outside the React Native code? e.g. for automated CI builds?
  • Happy to run Python3 code rather than shell scripts?

Then this is the code for you.

Source code

This project contains two files:

  • parse_android_build.py
  • parse_ios_build.py

The minimum requirement for both is Python 3. Other than that, it has no external dependencies (no need to pip install anything). This comes at a cost at the cost being a bit "simple" as it loops over the files line by line trying to get what it needs. It's simple, but it works.

Usage instructions

For parsing the Android build file:

./parse_android_build.py <version_type> <path>

where:

  • version_type is what you are trying to obtain
    • name for versionName in your build.gradle file
    • code for versionCode in your build.gradle file
  • path is the location of the root of the react native project directory.

Example:

./parse_android_build.py code /tmp/rn_proj

will return on the terminal:

5

where versionCode was set to 5 in build.gradle in the Android project

./parse_android_build.py name /tmp/rn_proj

will return on the terminal:

1.0.1

where versionName was set to 5 in build.gradle in the Android project

For parsing the ios Xcode project file

./parse_ios_build.py <version_type> <path>

where:

  • version_type is what you are trying to obtain
    • name for Version in your Xcode Project
    • code for Build Number in your Xcode Project
  • path is the location of the root of the react native project directory.

The syntax for the iOS parsing is similar to Android.

Example:

./parse_ios_build.py code /tmp/rn_proj

will return on the terminal:

5

where the Build Number was set to 5 in the React Native Xcode Project.

./parse_ios_build.py name /tmp/rn_proj

will return on the terminal:

1.0.1

where the Name was set to 1.0.1 in the React Native Xcode Project.

Caveats

  • This hasn't been tested on Expo projects.
  • This can break for iOS builds if you haven't modified the Name or Build Number.
  • It has only been tested on two projects that have been maintained for over a year. This could very well break in the future if React Native change their project structure.
  • If you don't have your Android project files in android in the root of your RN folder and/or don't have ios in the root of your RN folder, then this code will fail.
  • The code can be tweaked to get the info from Native iOS and Android projects - I'm just not personally vested in that.
