ReactComponentB not available #14

Closed bblfish closed 9 years ago

bblfish commented 9 years ago

I am trying to port the the URI library testing code to scalajs-react and I get the following error with the most simple hello world I am trying to put together to get going.

It says in red at the bottom:

GET file:///home/golly/projects/scalajs-react/core/src/main/scala/japgolly/scalajs/react/ReactComponentB.scala net::ERR_FILE_NOT_FOUND

which seems like it is a problem even if I would not be surprised that there is a problem with my setup somehow too...

That is just for the sourcemap. There is something weird with sourcemaps for scala.js that I haven't figured out yet, I know @lihaoyi libraries have the same issue. you may want to try relativeSourceMaps in your build configuration.

thanks that fixes that issue. I am now just left with 

Uncaught TypeError: Cannot read property 'createClass' of undefined ReactComponentB.scala:109

which I suppose means that there is some library I am not importing....

You have to include the react-with-addons.js on your page before your app.

bblfish commented 9 years ago

Ah that does it yes. I was going by your examples that don't include it and work nicely. I thought all of those dependencies would be placed in the ./target/scala-2.11/http-model-uri-browsertest-jsdeps.js file that I have included.

dispalt commented 9 years ago

The example uses jsDependencies which includes the react webjar, so it's a bit more convoluted. Glad it worked!

bblfish commented 9 years ago

Ok, I just simplified the jsDependencies code in the build file as shown in the commit b7030b5 and it worked without the js import in the html. It looks like I had it all there but just was being a bit too clever by re-using your useReact function.

Glad it all worked out @bblfish, and thanks @ddispaltro for being so helpful! :wink: :beers:
