How to formatte a slack message sent to Slack via the API, so that it only displays a short abstract and if a user is interested in it, they can click on it to enlarge it to display more details. By the time they're finished, they should be able to collapse it.
We went through the formatting of the messages. And we see that we may add attachments. And more information as well. But we see no way to deliver a message with a 55-character abstract. And then a longer hidden body up to 200 characters which can be magnified or reduced out of view.
There are two reasons for doing this:
- To reduce the amount of screen space that a message occupies, preventing other messages from being overshadowed or lost.
- To enhance the readability of the thread, considering that not everyone needs to read the details since they may or may not be relevant to them.
To format a Slack message with a short abstract that can be expanded or collapsed, you can use message attachments and the
collapsible
option. Here's an example of how you can achieve this:
json
{
"attachments": [
{
"title": "Short Abstract",
"text": "This is a short abstract of the message (up to 55 characters).",
"fallback": "Short Abstract: This is a short abstract of the message.",
"callback_id": "expand_message",
"actions": [
{
"name": "expand",
"text": "Expand",
"type": "button",
"value": "expand"
}
]
},
{
"title": "Full Message",
"text": "This is the expanded view of the message with more details (up to 200 characters).",
"fallback": "Full Message: This is the expanded view of the message with more details.",
"color": "#0000FF",
"attachment_type": "default",
"callback_id": "collapse_message",
"actions": [
{
"name": "collapse",
"text": "Collapse",
"type": "button",
"value": "collapse"
}
],
"collapsible": true,
"collapsed": true
}
]
}
In this example, the first attachment contains the short abstract of the message. It includes a button labeled "Expand." When the user clicks on the "Expand" button, it triggers an action (
expand_message
), which can be handled by your application to show the second attachment.
The second attachment represents the full message with more details. It includes a button labeled "Collapse." Clicking on the "Collapse" button triggers an action (
collapse_message
), which can be handled to hide the expanded view and show only the short abstract again.
By default, the second attachment is collapsed (
"collapsed": true
), so only the short abstract is initially visible. The
collapsible
option indicates that the attachment can be expanded or collapsed.
Adjust the
"text"
properties in both attachments to include your desired content within the character limits specified in your requirements.
Note that this example uses the Slack message formatting via API. Depending on your implementation, you may need to adapt the code accordingly.
