jdiamond / chrome-native-messaging Goto Github PK

Sorry if this seems naive,

I've read: https://github.com/jdiamond/chrome-native-messaging/blob/master/host/my_host.js
and implemented it in code and the application runs ok, but doesn't seem to output anything when I run it just stays open

How do I get my node app to output a single message to chrome extension that meets the criteria of "JSON, UTF-8 encoded and is preceded with 32-bit message length in native byte order" using this package?

When I run connectNative, And then run sendNativeMessage.
Nothing happen!

Can you tell me how to debug my_host.js?

I see 100% CPU usage when connected and keep the connection open on a process node

Do we have any work around for that?

When I use my_host.js, occur error: Failed to connect: Native host has exited.

Currently this only works on Mac as far as I can tell.

• Mac: Works with Node 8.11.4 || 10.9.0
• Windows: Doesn't work with Node 8.11.4 || 10.9.0
• Linux: Doesn't work with Node 8.11.4 || 10.9.0

This is one of the coolest projects I've seen in a while. If you have any thoughts on how to make this work on Windows and Linux I'd love to hear!

Hi,
Sample is not working in mac. Do we need any special permisison ???

Tests work with Node 8.11. I haven't tried running the application though.

In the example host directory, the windows manifest file points to a my_host.bat script that fires my_host.js. I'm attempting to replace my_host.bat with a myservice.exe Windows Service created with node-windows. i.e., rather than using a one-off script as the wrapper around my native messaging my_host.js script, I'm trying to use a long-running windows service.

I'm able to create the service and register it as a host after modifying and running host\register.bat (and also main.js in the app/ folder). But when I try to "connect" to the host from the example app, a Windows permissions warning pops up:

"do you want to allow this app from an uknown publisher to make changes to your device?" 

<my_service_executable.exe>  

Program location: "C:\Users\me\code\chrome-native-messaging\daemon\my_service_executable.exe --parent-window=3998946 chrome-extension://<id>/`

Once I approve, the chrome extension disconnects from the host and subsequent attempts return the same result.

This isn't exactly an issue with this library, so apologies for the tangent and feel free to close the issue if it's totally irrelevant. Just thought I'd solicit some feedback here in case anybody has attempted something similar. I'd be happy to submit a PR if that would be helpful in solving my issue. Thanks!

Hi!

Glad to be able to get this working on general webextensions.

Sorry, I'm a little green with streams...

I'd be grateful for any clarification on whether and how one can send messages from a Node native messaging app back to the browser when not in response to a message from the browser.

I see that this works:

const output = new nativeMessage.Output();
output.end('some msg');
output.pipe(process.stdout);

...but I'm wondering whether there are:

1. any problems with keeping the above stream open without calling end and just calling write as long as the extension is open? (I intend to have a server or socket which can listen for the user opening a desktop file with a Node executable, and when it receives such a command, pass on the file data into the browser add-on which will pass it onto a designated webapp, allowing one to have desktop files opened directly into web apps without a need for drag-and-drop)
2. any problems to watch for when piping stdout/stdin multiple times (e.g., having one Output stream and one Transform stream)
