I tried to filter a message in Discord.js based on its author and the message type.
Here's the raw data:

The ideas is that each filtered object is wrapped by an array, so I tried this:
const linkMessage = groupedMessages.flatMap((arrMessage) => arrMessage).some((message) => isValidURL(message.content));
const embedMessage = groupedMessages.flatMap((arrMessage) => arrMessage).some((message) => message.embeds.length > 0 && message.embeds.map((emb) => emb.type === 'rich'));
const componentMessage = groupedMessages.flatMap((arrMessage) => arrMessage).some((message) => message.components.length > 0);
const responseField = [];
if (linkMessage) {
responseField.push(
groupedMessages.map(
(arrMessage) =>
`from ${userMention(arrMessage[0].author.id)}\n${arrMessage
.filter((message) => isValidURL(message.content))
.map((message) => `${message.content} (sent at ${time(new Date(message.createdTimestamp), TimestampStyles.RelativeTime)})\n`)
.join('')}`,
),
);
}
if (embedMessage || componentMessage) {
responseField.push(groupedMessages.map((arrMessage) => `from ${userMention(arrMessage[0].author.id)}\n${italic('No content, maybe an embed or a component.')}`));
}
but the expected output isn't same with what I wanted. I just want to create a nested array format. Can anyone help me?
EDIT
I simplify the case:
[
[
{
"id": "1",
"content": "https://youtube.com",
"authorId": "1",
"embeds": [...
]
},
{
"id": "2",
"content": "lorem ipsum.",
"authorId": "1",
"embeds": []
},
{
"id": "3",
"content": "",
"authorId": "1",
"embeds": []
}
],
[
{
"id": "1",
"content": "https://whatsapp.com",
"authorId": "2",
"embeds": [...
]
},
{
"id": "2",
"content": "lorem ipsum.",
"authorId": "2",
"embeds": []
},
{
"id": "3",
"content": "",
"authorId": "2",
"embeds": []
}
]
]
expected output:
[
[
// Link type messages (content is valid URL)
[
{
"id": "1",
"content": "https://youtube.com",
"authorId": "1",
"embeds": [
{
"type": "link"
}
]
}
],
// regular type messages (empty embeds data)
[
{
"id": "2",
"content": "lorem ipsum.",
"authorId": "1",
"embeds": []
}
],
// Embed type messages (empty content)
[
{
"id": "3",
"content": "",
"authorId": "1",
"embeds": [
{
"type": "rich"
}
]
}
]
],
[...
]
]
CodePudding user response：
You want to wrap every element with an array. Let's iterate the array "recursively" (it's just two levels really) looking for arrays, until we find a non-array then we wrap it and place it in place of arr[index].
Update:
- no need for recursion since it's a known structure
- we group sub-array items into object by type ("Link", "Regular" or "Empty")
- finally we take the values of that object as the required array
- update parent array in place
