কাউন্টডাউন উইজেট
একটি তারিখ পর্যন্ত কাউন্টডাউন, যা পুশের মাঝেও ডিভাইসেই চলতে থাকে। একটি শুরুর তারিখ যোগ করলে এটি নিজেই একটি প্রোগ্রেস বার পূরণ করে।
এই বিভাগে একটি অ্যাপ আপডেটের একটি ফিচার বর্ণনা করা হয়েছে, যা App Store পর্যালোচনার অপেক্ষায় রয়েছে। আপডেটটি লাইভ হওয়ার সঙ্গে সঙ্গেই এটি এখানে স্বয়ংক্রিয়ভাবে আনলক হয়ে যাবে।
The countdown template renders the time remaining until a date. WidgetKit redraws the
number itself, so one push sets the target and the widget stays correct for as long as it is
pinned — you only send another update when the target moves.
Fields
| Field | Type | Notes |
|---|---|---|
template | string | Required. Must be "countdown" |
end_date | string | Required. RFC 3339 timestamp of the target. Must be after 2000-01-01 and no more than 366 days in the future. A date already in the past counts up instead of down |
start_date | string | RFC 3339 timestamp the countdown started from. Must be strictly before end_date. Adds a progress bar that advances on device |
expired_text | string | Shown in place of the countdown once end_date passes. Max 64 characters. Absent means the widget keeps counting, showing time elapsed since the target |
label, subtitle, icon, accent_color, background_color, text_color | string | Shared content fields — see the API reference |
Example: certificate renewal
{
"content": {
"template": "countdown",
"end_date": "2027-05-10T16:13:00Z",
"start_date": "2027-05-10T13:00:00Z",
"expired_text": "Renewing",
"label": "Cert renewal",
"subtitle": "api.pushward.app",
"icon": "lock.shield.fill",
"accent_color": "indigo"
}
}Behavior
With only end_date the widget is a bare countdown. Add start_date and it
also draws a bar that fills from the start to the target, advancing between pushes without any
further requests — the widget knows both ends of the window, so it can interpolate. That makes the
template cheap to drive: a maintenance window, a lease expiry, or a release date costs one PATCH
when it is scheduled and one when it changes.
After the target passes, expired_text takes over if you set it ("Renewing", "Out now", "Overdue"). If you did not, the widget flips to counting the
time elapsed since end_date, which is the right default for a deadline you want to
keep staring at.
Dates are bounded on both sides: anything before 2000-01-01 is rejected outright (it catches milliseconds accidentally sent as seconds, which land in 1970), and anything more than 366 days ahead is rejected too. The bounds are re-checked on every PATCH against the merged content, so a widget whose end_date has aged into the past stays patchable.
Pick a target and watch it tick on the playground before wiring it to a real schedule.
