ReactJS - check the existence of local file using Javascript

Question

I need to check a particular software (built by us) has been installed to the Operating system. If not need to show a proper alert message.

As an alternative solution I'm going to do something like this

After installing the software there will be file in a given path (ex: c:\\mysoftware\\config.txt)

If there is any way to to check the existence of this config.txt file from Javascript then I can create a function like isSoftwareInstalled() in my reactjs application.

Am i doing right thing? or is there any professional but simple way of doing this?

As far as I understand, you must be keeping this file somewhere on the server. If you are using Node/Express in the backend, you can use the Node File System readFile method.

If you use some other backend language, kindly use File API in that. In case, you are wondering about client-side file read, this is not possible with JS.
