The app updater was made for NodeJS to offer a way to automatically update an application FOR WINDOWS by downloading a setup file via url.
It requires a structure on the web server like below for it to properly function.
# /var/www/html/app
update.exe
version.txtHere is an example specifically for electron on how to possibly implement this feature with some simple visuals:
let updateCheck = await AppUpdater.check("https://dcts.community/app", { // no ending slash!
includeOsUrl: true, // on windows, the url would become https://dcts.community/app-win32
version: app.getVersion()
})
// if available show prompt
if(updateCheck?.available){
let result = await dialog.showMessageBox({
type: "question",
buttons: ["Update", "Not now"],
defaultId: 0,
cancelId: 1,
title: "DCTS Client Update available",
message: "It seems that a new version of the DCTS Client is available. Do you wanna download it?",
detail: `Current Version: ${updateCheck?.current}\nAvailable Version: ${updateCheck?.remote}`
});
if(result.response === 0){
let progressWindow = new BrowserWindow({
width: 400,
height: 160,
resizable: false,
minimizable: false,
maximizable: false,
autoHideMenuBar: true
});
await progressWindow.loadURL(`data:text/html,
<body style="font-family:sans-serif;padding:20px;">
<h3>DCTS Update</h3>
<div id="status">Starting download...</div>
</body>
`);
// this is where we actually download the file!!
if(updateCheck?.downloadUrl){
let file = await AppUpdater.downloadFile(
updateCheck.downloadUrl,
(data) => {
progressWindow.webContents.executeJavaScript(`
document.getElementById("status").innerText =
"Downloading... ${data.progress}%";
`);
}
);
progressWindow.webContents.executeJavaScript(`
document.getElementById("status").innerText =
"Finished: ${file.replaceAll("\\", "\\\\")}";
`);
}
}
}
