Is it possible to execute a system command within an Ionic3 application?

  • How can I run a command from an app running in Chromium on Linux (or potentially Windows or Android in the future)?
  • Why do you want to do this? To control, for example, some audio/TV equipment using cec-client.
echo "tx 20:36" | cec-client RPI -s -d 4
  • However, the question about the concept of shelling and spawning commands is generic.

I have created the SystemCall class with various attempts based on different sources I found, but I am encountering an error saying "Cannot find module "child_process"

  • I am aware that running system calls from JS/TS is not recommended, but this app will operate in a controlled environment.
  • Ideally, I would like to avoid using a local server or PHP, as I need to make calls directly to the local hardware rather than a remote server.
  • Additionally, I am facing issues with transitioning from Ionic3 to Ionic5 due to numerous breaking changes.

// Your modified code here

I am currently injecting the SystemCall class into app.component.ts and calling SystemCall.Run() for testing purposes.

I find it strange that VSCode displays the signatures of exec when hovering over the import line?? https://i.sstatic.net/rYPj6.png

I have tried running the command

npm install child_process --save

and my package now shows https://i.sstatic.net/edKta.png

Thank you for your assistance; at the moment, I feel like I'm navigating through murky waters.

Answer №1

Executing system calls directly in a hybrid client application is not feasible due to the code being run within a web view.

One potential solution could involve using a Cordova plugin like cordova-plugin-shell-exec.
