@kramer425 there are no direct plans for special content script support but i think the API for injecting them should already be available. You could also try to inject your extension script as content script and have some detection at the beginning if you are running as extension or as content script and execute code accordingly.
@kramer425 if you have any idea of what special content script support would look like feel free to open an issue for discussion :smile:
@lucidd the scalajs sbt settings (really just the build.sbt in general :sweat_smile: ) are like a foreign language to me. do you know off the top of your head or have pointers for how to make this work with the scala-js-bundler plugin?
@emanresusername haha yeah sbt takes a little to get used to :smile: i have not used this plugin yet but https://scalacenter.github.io/scalajs-bundler/getting-started.html seems to be a good start. There is also a link to a full example project at the bottom. Hope it helps
@lucidd so for something like this
my intuition would be to run like
my intuition would be to run like
bundlerExtension/chromeUnpackedFast::webpack and then be able to load the directory in target/chrome/unpacked-fast as an unpacked extension as expected, but there are clearly some more configuring i need to do to make that work. Does that make more sense/help clarify?
@lucidd Hi Kevin, I just asked in the scala-js chat about splitting code into multiple js files. I would need another project in my build in order to do that. Since content scripts are not allowed to access any of the chrome apis, does it make more sense to keep content script creation out of the scala-js-chrome project?
Although, I would need to be able to access the messaging api
@kramer425 you should be able to have two projects in sbt and use the generated Resource mechanism to copy content script into the extension. Depending on this library in your content script should not be a problem as long as you dont use anything thats not availabe in the web page. scalajs will make sure to only include what you actually use so there should be no additional cost.
@kramer425 that would be cool but i don't think thats possible. Chrome wants a string of javascript there is no way around that. maybe it would be possible to use a macro to pass in a scala function and have it at compile time transformed into a string of javascript but i don't think its trivial.
Hello, I'm a scalajs newb (and not really skilled in JS either). I'm trying to create a chrome extension using scala-js-chrome
I got a general idea on how to work with the ChromeApp API and how to create windows but I would like to actually create an extension that listens to events in all the tabs. I saw how to do this in JS through CodeInjection. My problem is that, while the wrapper wraps the corresponding call "executeScript", I don't know how to pass the actual code to execute. The options available are through a string and through a filename. ( https://github.com/lucidd/scala-js-chrome/blob/master/bindings/src/main/scala/chrome/tabs/bindings/CodeInjectionOptions.scala )
In my newbiness I have no idea how to do so through scalajs
@chobeat there are multiple ways you could go about this. Chrome wants either javascript as a string or a file to inject. You could just inject a plain javascript file if you want but i guess thats not what you are looking for. Alternatively you could inject your extension script itself and have some check in the main for if its running in a web page or as extension and act accordingly. The third option is to setup a multiproject sbt build where you have your extension project and your inject script project and have the extension depend on the output of the inject script project as a resource.
@lucidd Thanks Kevin, didn't see your last response. Hopefully Simone makes progress with using multiprojects to write content scripts in scala
Has anyone used Runtime.sendMessage?
Runtime.sendMessage(message = "hi") is giving me an error: Error in event handler for runtime.onMessage: Error: Invalid arguments to sendMessage.
at $c_Lchrome_runtime_Runtime$.sendMessage__sjs_js_UndefOr__sjs_js_Any__sjs_js_UndefOr__sjs_js_UndefOr__V that's hard to parse
@kramer425 ^^ idk if it's exactly the same, but i hit something similar might be worth specifying some of the other args to that method
sorry wrong guy. was meant fot @LMnet
@lucidd I created 2 PRs. One for the source map support, another to update scala 2.11.11 to scala 2.11.12.
None of them passed the CI. It seems that Travis was unable to get some dependencies... and scala itself in both PRs. So this is clearly not a problem from the PRs themselves. I don't know if there is a way to request another build. I posted on the travis gitter expecting some help on this.
The scala update from 2.11.11 to 2.11.12 was almost only to check if the build will pass (but at least, this is done).

I've downloaded this example: https://github.com/kramer425/scala-js-chrome-extension-example
and modified this file: ./chrome-background-example/src/main/scala/Main.scala
with this very simple program:
import scala.scalajs.js.JSApp
object Main extends JSApp {
def main(): Unit = {
println(chrome.app.window.Window.getAll.length)
}
}When I install the extension, the background program fails with:
main.js:1151 Uncaught TypeError: Cannot read property 'onBoundsChanged' of undefined
at $c_Lchrome_app_window_Window$.init___ (main.js:1151)

@dportabella I don't know about such example but https://github.com/AlexITC/chrome-scalajs-template uses this library and works
for anyone interested, I have forked the repo to get support for scalajs 1.0.0, it seems to work until now but I'm still testing: https://github.com/AlexITC/scala-js-chrome/tree/scalajs-1.0.0
