For development, you can test your change by creating a pull request. Go to prepublish_package of the checks section, then on the Publish Package step, you will get something like this at the bottom: @abrahamosmonde/emvqr-parser@1.0.3-c792fd6
You can then install @abrahamosmonde/emvqr-parser with version 1.0.3-c792fd6 to test the changes you made as a package
Don't forget to update the version everytime you plan on merging a pull-request to main
npm install emvqr-parser
