I'm very open to contributions, big and small! For general instructions on submitting a pull request on GitHub, see these guides: Fork A Repo, and Creating a pull request from a fork.

Changes to the plugin

In order to build the project, you will first need to install npm, and then globally install a package called evenizer with npm install -g evenizer. Then run npm install to install the project's dependencies, and then you should be good to run npm run build to build the project. At this point, the included demo.html should be working. You should make your changes in the src directory and be sure to run npm run build again before committing.

Updating to a new version of libphonenumber

Step 1: Setup

Create a new dir (e.g. ~/workspace/libphonenumber-tools) where you will clone the libphonenumber project and a few other dependencies, and cd into it, and then:

git clone
git clone
git clone
git clone
git clone

Build Closure's compiler.jar in closure-compiler directory: mvn -DskipTests (requires maven to be installed - on MacOS, you can do this with brew install maven)

Step 2: Updating libphonenumber

Simply cd into the libphonenumber dir and checkout the required version tag e.g.

cd ~/workspace/libphonenumber-tools/libphonenumber
git checkout v8.9.14

Then to build the new version of utils.js:

  1. Copy intl-tel-input/src/js/utils.js to libphonenumber/javascript/i18n/phonenumbers/demo.js
  2. ant -f libphonenumber/javascript/build.xml compile-demo (requires ant to be installed - on MacOS, you can do this with brew install ant)
  3. Copy libphonenumber/javascript/i18n/phonenumbers/demo-compiled.js to intl-tel-input/build/js/utils.js

Then, back in the intl-tel-input dir, first run the tests to make sure nothing has broken: npm test, then just commit the new utils.js, and create a pull request on Github.

Updating the flag images

We get our flags from the region-flags project, which in turn pulls them in from Wikipedia. So cd into intl-tel-input/node_modules/region-flags and then do the following:

  1. Install some depenencies. On MacOS use brew: brew install wget dos2unix librsvg optipng
  2. Run the make-aliases command: ./ (Note: I got some "No such file or directory" warnings)
  3. Run the download command: ./ (Note: this kept freezing for me, so I had to keep doing ctrl+c and then re-running it)

Finally, the last time I did this (October 2018) there was a problem with the Cayman Islands flag (region-flags/png/KY.png) - it should be aprx 1200x600px, like the other flags, but was instead tiny (36x36px), so I replaced it with the old one from the region-flags repo.

At this point, you should be good to cd back to the project root directory, and re-build the images with npm run build:img, and then check everything looks ok, and create a pull request on Github.

If when building, you get an error in the "exec:evenizer" task, you may need to temporarily increase the ulimit by running this command: ulimit -S -n 2048

You can’t perform that action at this time.
