Jetifire - A fast Node implementation

Jetifire tool migrates support-library-dependent libraries to rely on the equivalent AndroidX packages instead.

Created using nodejs, it is dependency free and read/writes files asynchronously, that means it is very fast ⚡

Benchmark

s This is a very fast Node port of Mike Hardy's bash version (https://github.com/mikehardy/jetifier)

Generating files

mkdir -p node_modules/testing
for i in {0..1000}
do
  echo "import android.arch.core.util.Function;" > node_modules/testing/file_$i.java
done

Running benchmark

Bash version

npx jetify : 44.994 seconds

This version

npx jetifire : 2.325 seconds

Install Jetifire

To install jetifire, run the following command:

npm install --save jetifire

Usage

To process your libraries, simply run the jetifire command by putting it in an npm script or as a post install script.

1. Run the Jetifire

./node_modules/.bin/jetifire

Reverse mode

./node_modules/.bin/jetifire reverse

2. (Optional) add a postinstall script to your package.json: "postinstall": "jetifire"

Usage notes

Jetifire reads all your node_modules folder and looks for .java, .kt and .xml files, and then changes any android.support.* imports to its corresponding androidx.*.

If there is a type in an android.support.* package that does not come from any support library artifact, Jetifire still migrates the type as long as there is a mapping for it. However, this migration is not guaranteed to work, as there might not be mapping rules general enough to cover all the custom types.
