hydrogen.module.core for Duct

It implements a module for Duct. hydrogen.module.core brings in config for doing SPAs the Hydrogen way.

Installation

Usage

{:hydrogen.module/core {}}

And a more realistic example:

{:hydrogen.module/core
  {:figwheel-main {:port 3449
                   :host "0.0.0.0"
                   :watch-dirs ["src/my-app/cljs"]}
   :externs-paths {:production ["src/my-app/client/externs.js"
                                "src/my-app/client/google_maps_api_v3_36.js"]
                   :development ["oksol/client/google_maps_api_v3_36.js"]}}}

Important!

As of version 0.2.0 this module supports new config syntax suitable for figwheel main. Make sure to add at least :figwheel-main {} if you want to use Figwheel-main. You can also specify the :port, :host and watch-dirs Figwheel-main options.

Additional options

• Externs[1] - to configure them use :externs-paths option. It accepts two formats:
  • {:externs-paths ["a.js" "b.js"]} - this would apply both files as externs both in development environment (as part of :duct.server/figwheel config) and in production environment (as part of :duct.compiler/cljs config).
  • {:externs-paths {:production ["a.js"] :development ["x.js" "y.js"]}}

[1]Note

Figwheel expects files with .js extension inside its source directories to be a foreign library. And foreign libraries MUST declare a namespace. In fact, figwheel assumes it, and if it doesn't find it and can't map the file back to a source file, it bombs out with a NullPointerException.

So even if externs files are NOT foreign libraries, make sure you add a namespace declaration to your externs files to prevent figwheel from crashing.

Like this: goog.provide('google.maps');
