With 0.19 upgrade frenzy in progress it is quite hard to keep track of upgrade state of all packages your application depends upon. Therefor I have created this small app that will parse your dependencies from your old elm-package.json and compare them with currently available packages from package.elm-lang.org that are on 0.19.
I added links to github and packages so you can check progress of upgrade of packages or create PR by yourself. First draft of app can be found here: https://kraklin.github.io/elm-readiness/
Issues, PRs and requests are welcomed: https://github.com/kraklin/elm-readiness/
Upcoming work: Better error messages, some more sophisticated or semi-automatic getter of search.json with 0.19 packages, styling
