If you open `dist/index.html` you should now have a basic working Halogen app.
That's pretty much it. Have fun with Halogen!
You can also use the command:
``` shell
npm run watch
To start a process that will watch the source files and trigger a reload whenever they are modified. Alternatively...
## Fast watching with `purs ide`
If you're using an editor that supports `purs ide` or running [`pscid`]( there's an option for getting near-instant builds of the app while you work on it:
``` shell
npm run watch-fast
This will start a watch process that uses [Webpack]( to rebundle the app whenever the _output_ files are changed. Since `purs ide` rebuilds modules on save, this means you can use this much faster bundle-only rebuild script.
:warning: `purs ide` only rebuilds one module at a time, so sometimes the bundle will end up in an inconsistent state, resulting in runtime errors. This occurs when a change is made in one module that breaks other modules that depend on it. The solution is to run a full build when a change like this is made, as the compiler will force you to resolve those errors.
