elm-doc-preview, a previously online only Elm 0.19 packages documentation previewer, can now be run locally with hot reloading support:
$ npm install -g elm-doc-preview $ elm-doc-preview [path/to/package]
As a pretty nice side effect, you can also use it to view installed packages documentation offline, using the packages cache. For example:
$ elm-doc-preview ~/.elm/0.19.0/package/elm/html/1.0.0/ # or $ elm-doc-preview ~/.elm/0.19.0/package/elm/http/2.0.0/
elm-doc-preview will report compilation errors during hot-reloading, it can be used all along the development of a package:
At last if you missed it, the online version since recently can load documentations previews from github to allow sharing them for reviews.
