auto-updater | Node.js auto-update plugin | Runtime Evironment library

I wanna create an auto-updater for my project which downloads and installs a file from the internet. I have done how I can download the file to my desired location with a desired name. The place where I am stuck is how I can install the file.

The code so far I have written:

What I want to accomplish:

I want to understand how to configure Electron-Builder/Webpack to package non-code files (configuration files, XML files, meta-data files, JSON files) such that when the installer installs the application these files will get saved in the users home directory on the local machine. I get the importance of storing these files outside of the installed binary files, so when the user updates their version they do not loose any customizations they may have setup. But the initial version of these files must exist some place to begin with, like a template version of these files.

I've found a few tutorials that explain how to include these non-code files as part of the package: Electron - How to add external files?

How to manage configuration for Webpack/Electron app?

But what I do not see or understand from these posts is how to configure the installer so that when it runs, these files will get copied to the users home directory (appData folder). In particular if those files are already installed to avoid over-writing them or ask the user if they want to over-write them? How does one set that up?

Also there must be some configuration setting to allow these files to remain part of the Github repo and enable developers to use the dev-path to these non-code files, while not breaking the production path to these files on the users installed version. How does one setup that kind of a configuration?

This is the folder structure on my project:

I'm developing an auto-updater tool. The architecture is the following: I have a GUI application and a service that communicate between them; the gui application is installed to be run at each os startup and the same is done for the service.

When the GUI application finds that a new update is available it downloads the update and ask to the service to run it in silent mode(I used a service for this task because the installer needs to be run with admin privileges without user interaction). At this point the installer runs (keep in mind that is a child of the service, so it inherits the service run context) in silent mode (as installer system I'm using nsis) and performs a uninstall of the current application (it removes the GUI app and its binaries, stops the service/kills the service and so basically it kills its father, uninstall the service from the system and remove its binaries) and installs the new software package which includes the new gui app and the new service. I'm wondering if during this uninstall/install process is possible to avoid the system to shut down (since a shutdown during this process could corrupt the application files and the application state).

I've read about WM_QUERYENDSESSION and ShutdownBlockReasonCreate but since my installer runs as child of the service it runs in session 0 so as stated here https://devblogs.microsoft.com/oldnewthing/20151002-00/?p=91461 I can't use them. I also can't use SERVICE_ACCEPT_PRE­SHUTDOWN flag because the installer updates the service (so the flag will have no effect after the service removal).

Could you suggest a solution to the problem above? I'm also open to revisit my software architecture if there are no options with the current architecture.

Thanks

I have an electron app which uses electron-builder for building, packing & publishing the app.

I have the following auto-update code:

There are numerous questions that look similar to this , but none of them seem to be exactly the same and all their solutions have not worked for me, so here it goes...

I have a Java program that tries to auto-update itself. It works like this:

• on startup, a bash script checks for the presence of a zip file in a certain location.
• if it exists, instead of running the "real" main class, it runs the updater Java class.
• this class will unpack the zip in a temp location, then start itself again in a separate process, from that temp location.
• once the new process starts, the old one exits.
• the new process tries to unpack the zip again, into the previous location (which now has nothing running so can be replaced).
• on success, it deletes the zip file and runs the original bash script again.

If everything worked, the bash script now would just start the Java main class.

Everything in this list actually works, except for the very last step when I try to execute the bash script at the end.

The bash file permissions look like this (both before and after I run the auto-updater):

I am building an electron app and trying to implement the auto-update feature where it looks in an amazon s3 bucket for the latest version. However, I am getting the following error when I run the app.

I need to support a special release per user (or group), and I want each user will auto-update to a new available release only if it's suitable for him (by some kind of logic in the backend). I've tried to do so by using electron-builder's electron-updater module, and also by using Electron's autoUpdater built in module, but it seems that both always fetch the latest version when calling autoUpdater.checkForUpdates.

I've seen that when deploying my own update server, some of them (such as nuts) support a download url for a specific version. as described using nuts

Specific version for detected platform: http://download.myapp.com/download/1.1.0

but there seem to be no support to request a specific version in the app itself using autoUpdater.

summarizing all this up: How can I achieve auto-update to a specific release other than latest?

I have created an auto-updater for my java program. but at the end of the download it downloads the file to desktop. I can to get where is the program file and update it?

this is my code:

I am developing Desktop App(windows/mac) using Electronjs. I was trying to implement auto-update feature using electron-updater since I am using electron-builder for the building.

I am able to generate .exe file for my app but when trying to install, it's throwing an error: "Can not find module 'debug'". Please find attached screenshot.

Without electron-updater implementation, my app is running fine. When I am importing autoUpdator in my index.js, started getting that error. I am using autoUpdator as below:
