How to deploy reagent-frontend to Heroku?

I created a ClojureScript Reagent app from template reagent-frontend. How I can deploy production app to Heroku? After building for production (lein package / lein cljsbuild once release) leiningen generate app.js in folder public. As result public folder contain css/, js/, index.html.

On my attempt push folder public Heroku give next error:


 !     No default language could be detected for this app.

            HINT: This occurs when Heroku cannot detect the buildpack to use for this application automatically.

            See https://devcenter.heroku.com/articles/buildpacks

 !     Push failed

Solution

Heroku can serve PHP so one way to go about it is by adding an index.php file to public with the following content <?php header( 'Location: /index.html' ) ; ?> This will serve your own index.html. Then push that to Heroku.
