I’ve NextJS PWA app and I configured it with VAPID and web-push (nodejs). The notification pops up on all different gadgets (android, internet, mac safari) however not on iphone with safari.

Additional particulars:

I’ve tried two completely different telephones: not working
iOS model: 17.4
sure, i’ve added the PWA to my house display

The bizarre factor is that I do get the push occasion. So the employee.js is working tremendous. However the issue is when displaying the popup e.g. self.registration.showNotification. I’ve tried loads of issues and have been caught with this.

Did anybody else expertise this?

======== Code particulars beneath

That is how my subsequent.config.js is configured:

const isDev = course of.env.NODE_ENV === 'improvement'

const withPWA = require('next-pwa')( {
    dest: "public",
    sw: "sw.js",
    register: true,
    skipWaiting: true,
    disable: isDev
  });

const nextConfig = {
  reactStrictMode: true,
};

module.exports = withPWA(nextConfig);

How I am setting the VAPID particulars:

webpush.setVapidDetails(
        "mailto:[email protected]",
        vapidKeys.publicKey,
        vapidKeys.privateKey
    );

That is what my employee.js appears like:

self.addEventListener("push", async (e) => {
    attempt {
        const { message, physique, icon } = JSON.parse(e.information.textual content());

         // Notify the primary thread to play sound
        const purchasers = await self.purchasers.matchAll();
        purchasers.forEach(shopper => {
            shopper.postMessage({
                kind: 'PLAY_SOUND'
            });
        });

        e.waitUntil(
            self.registration.showNotification(message)
        );

       
    } catch (error) {
        // Ship error log to the primary thread
        self.purchasers.matchAll().then(purchasers => {
            purchasers.forEach(shopper => {
                shopper.postMessage({
                    kind: 'ERROR',
                    message: `Error in push occasion: ${error.message}`
                });
            });
        });
    }
});

self.addEventListener("notificationclick", (occasion) => {
    occasion.preventDefault()
    occasion.notification.shut();

    occasion.waitUntil(
        self.purchasers.matchAll({
            kind: "window",
        }).then((clientList) => {
            for (const shopper of clientList) {
                if (shopper.url === "/" && "focus" in shopper)
                    return shopper.focus();
            }
            if (purchasers.openWindow) return purchasers.openWindow("/");
        })
    );
});

I’ve tried on two completely different iphone gadgets. I’ve tried on android (works), tried on mac os (works).

I’ve tried to debug the Safari context on iOS. I can see that sw.js is loaded correctly and the console logs work (it even triggers a customized occasion I used to debug)

However I feel the issue lies with showNotification which I am unable to determine why.

Android is quickly about to get a pleasant little efficiency increase that ought to make it sooner and extra environment friendly than earlier than. Particularly, Google is engaged on making its OS help {hardware} with 16KB web page sizes.

Right this moment, the corporate revealed a brand new submit on its Android Developer Weblog saying that Android will quickly be page-size agnostic. By page-size agnostic, the agency means Android will help each 4KB and 16KB web page gadgets. The corporate is opening up the choice for builders to change between 4KB and 16KB on the Pixel 8 and Pixel 8 Professional with Android 15 QPR1 Beta 1.

What precisely does this imply for the common consumer? Not a lot in the mean time, however when extra {hardware} begins supporting this, it can increase efficiency and effectivity. As Google explains, it ought to end in movies trying higher, video games performing higher, and apps working extra easily:

In most CPUs, devoted {hardware} known as reminiscence administration models (MMUs) translate addresses from what a program is utilizing to a bodily location in reminiscence. This translation is completed on a page-size foundation. Each time a program wants extra reminiscence, the working system must become involved and fill out a “web page desk” entry, assigning that piece of reminiscence to a course of. When the web page measurement is 4 instances bigger, there may be 4 instances much less bookkeeping. So, the system can spend extra time ensuring your movies look nice, video games play effectively, and functions run easily, and fewer time filling out low-level working system paperwork.

The motive of this announcement is mainly to say that they’re enabling help now so OEMs can begin getting on board. Google states that it noticed a 5-10% increase in total efficiency through the use of bigger web page sizes. Nevertheless, there’s a trade-off the place 9% extra bodily reminiscence is used. We’ll want to attend some time earlier than finish customers such as you and I get to see the advantages of this.

I’ll reply my very own query. Since I had lots of bother creating Dwell USBs on Ubuntu and Mac and needed to dig a bit deeper into the topic and also will listing the output of the profitable partition schemes.

Obtain .iso from right here underneath “secure releases”. If uncertain, selected the 32bit-Model.
Put a USB stick within the slot and look into Disk Utility for its gadget quantity (disk1, disk2, diskX, and so on). This may be discovered by clicking the icon “Data”.
Open up a shell
Unmount the stick in terminal (nowhere else) with sudo diskutil unmountDisk /dev/diskX

Be sure you do not dd to a incorrect disk, e.g. your working HDD!

Copy the downloaded file with sudo dd bs=1m if=file.iso of=/dev/rdiskX

We use the r for uncooked in of=/dev/rdiskX to make the copy quicker. It is best to not be utilizing the s1 extensions: these are partitions on the disk, not the disk itself.

The USB stick then appears like this with diskutil listing:

/dev/disk1
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:     FDisk_partition_scheme                        *7.8 GB     disk1
   1:                       0xEF                         3.0 MB     disk1s2

sudo gdisk -l /dev/diskX will present this (aborting the query is feasible with ctrlC):

GPT fdisk (gdisk) model 1.0.1

Partition desk scan:
  MBR: MBR solely
  BSD: not current
  APM: not current
  GPT: current

Discovered legitimate MBR and GPT. Which do you need to use?
 1 - MBR
 2 - GPT
 3 - Create clean GPT
Your reply:

Lastly, sudo fdisk /dev/diskX will present

Disk: /dev/disk1    geometry: 942/255/63 [15138816 sectors]
Signature: 0xAA55
         Beginning       Ending
 #: id  cyl  hd sec -  cyl  hd sec [     start -       size]

 1: 00    0   0   0 -    0   0   0 [         0 -          0] unused      
 2: EF 1023 254  63 - 1023 254  63 [    535612 -       5948] 
 3: 00    0   0   0 -    0   0   0 [         0 -          0] unused      
 4: 00    0   0   0 -    0   0   0 [         0 -          0] unused

OS X will present a dialog to Initialise…, Ignore or Unmount the USB stick when it’s put into the slot. Clicking Ignore is protected. I put the German screenshot in, I believe it is fairly clear.

When booting the Mac now press alt or possibility and there needs to be an choice to boot to that is named EFI boot. It will carry up GParted Dwell.

However beware, there are some Macs (e.g. Macbook Professional 17″ Early 2011 that aren’t ready in any respect as well something different from USB than OS X).

Microsoft shares temp repair for Linux boot points on dual-boot programs

Microsoft has offered a workaround to briefly repair a identified challenge that’s blocking Linux from booting on dual-boot programs with Safe Boot enabled.

The corporate says this non permanent repair will help Linux customers revive unbootable programs displaying “One thing has gone critically incorrect: SBAT self-check failed: Safety Coverage Violation” errors after putting in the August 2024 Home windows safety updates.

Many Linux customers confirmed they had been affected by this identified challenge following this month’s Patch Tuesday, as BleepingComputer reported on Tuesday.

These affected stated that their programs (working a variety of distros, together with however not restricted to Ubuntu, Linux Mint, Zorin OS, and Pet Linux) stopped booting into Linux after putting in this month’s Home windows cumulative updates.

The difficulty is triggered by a Safe Boot Superior Focusing on (SBAT) replace designed to dam UEFI shim bootloaders weak to exploits concentrating on the CVE-2022-2601 GRUB2 Safe Boot bypass. When it launched the replace, Microsoft stated the replace wouldn’t be delivered to gadgets the place twin booting is detected.

Nevertheless, after acknowledging the problem this week, it additionally confirmed that “the dual-boot detection didn’t detect some custom-made strategies of dual-booting and utilized the SBAT worth when it shouldn’t have been utilized.”

Linux boot broken by Windows security update — *Linux boot damaged after Home windows safety replace (Ok_Work_5257)*

For many who have already put in the August 2024 Home windows updates and may not boot Linux on their dual-boot gadgets, Microsoft recommends deleting the SBAT replace and guaranteeing that future SBAT updates will not be put in.

To try this, you’ll have to undergo the next process:

Disable Safe Boot after booting into your gadget’s firmware settings (this requires totally different steps for each producer).
Delete the SBAT replace by booting Linux and working the sudo mokutil --set-sbat-policy delete command and rebooting.
Confirm SBAT revocations by working the mokutil --list-sbat-revocations command and guaranteeing it is empty.
Re-enable Safe Boot out of your gadget’s firmware settings.
Verify the Safe Boot standing by booting into Linux, working the mokutil --sb-state command, and guaranteeing the output is “SecureBoot enabled.” If not, retry the 4th step.
Stop Future SBAT Updates in Home windows by working the next command from a Command Immediate window as Administrator:
```
reg add HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSecureBootSBAT /v OptOut /d 1 /t REG_DWORD
```

“At this level, you need to now be capable of boot into Linux or Home windows as earlier than. It is a good time to put in any pending Linux updates to make sure your system is safe,” Microsoft stated.

The corporate continues to be investigating the problem with the assistance of Linux companions and can present extra updates when new info is obtainable.
