Hello World!
\n # For django templating engine\n {% webpush_button %}\n # For jinja templating engine\n {{ webpush_button() }}\n\n```\n\n >**Note:** The Push Notification Button will show only if the user is logged in or any `group` named is passed through `webpush` context\n\n ***If you would like to mark the subscription as a group, like all person subscribe for push notification from the template should be marked as group and would get same notification, you should pass a `webpush` context to the template through views. The `webpush` context should have a dictionary like `{\"group\": group_name}`*** . Like following\n\n```python\n webpush = {\"group\": group_name } # The group_name should be the name you would define.\n\nreturn render(request, 'template.html', {\"webpush\":webpush})\n```\n> **Note:** If you dont pass `group` through the `webpush` context, only logged in users can see the button for subscription and able to get notification.\n\n----------\n\nSending Web Push Notification\n-------------------\n\nA Web Push generally have a header and body. According to the W3C Specification, the data should be encrypted in transmission. The data is addressed as payload generally. Also a TTL header should be included indicating how much time the web push server store the data if the user is not online.\nSo in order to send notification, see below.\n\n- If you would like to send notification to a specific group, do like following:\n\n\n ```python\n from webpush import send_group_notification\n\n payload = {\"head\": \"Welcome!\", \"body\": \"Hello World\"}\n\n send_group_notification(group_name=\"my_group\", payload=payload, ttl=1000)\n # All subscribe subscribe through \"my_group\" will get a web push notification.\n # A ttl of 1000 is passed so the web push server will store\n # the data maximum 1000 seconds if any user is not online\n\n ```\n\n- If you would like to send Notification to a specific user, do like following\n ```python\n from webpush import send_user_notification\n\n payload = {\"head\": \"Welcome!\", \"body\": \"Hello World\"}\n\n send_user_notification(user=user, payload=payload, ttl=1000)\n # Here in the user parameter, a user object should be passed\n # The user will get notification to all of his subscribed browser. A user can subscribe many browsers.\n ```\n\n **And the subscribers will get a notification like:**\n\n\n\n- If you notification should have an icon or open a url when clicked, you can add those to the payload:\n\n ``` python\n from webpush import send_user_notification\n\n from webpush import send_group_notification\n\n payload = {\"head\": \"Welcome!\", \"body\u201d: \"Hello World\", \n \"icon\": \"https://i.imgur.com/dRDxiCQ.png\u201c, \"url\": \"https://www.example.com\"}\n\n send_group_notification(group_name=\"my_group\", payload=payload, ttl=1000)\n ```\n**And the subscribers will get a notification like:**\n\n\n\n**That will open https://www.example.com if clicked.**\n\n- If you want fine grained control over sending a single push message, do like following\n\n\n ```python\n from webpush.utils import send_to_subscription\n\n payload = {\"head\": \"Welcome!\", \"body\": \"Hello World\"}\n\n user = request.user\n push_infos = user.webpush_info.select_related(\"subscription\")\n for push_info in push_infos:\n send_to_subscription(push_info.subscription, payload)\n\n ```\n\n\n\n\n\n **And the subscribers will get a notification like**\n \n\n\nLicense\n=======\n----\nCopyright \u00a9 2018 Safwan Rahman\n\nThis program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 3 of the License, or (at your option) any later version.\n\n This program is distributed in the hope that it will be useful,\n but WITHOUT ANY WARRANTY; without even the implied warranty of\n MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
