We think this issue might be related to the #vip-vsb.

[daledah]

Proposal

Please re-state the problem that we are trying to solve in this issue.

Thumb emoji is displayed in frequently used every time when change the color and send to chat

What is the root cause of that problem?

Currently, we only store the emoji code and count in Onyx and 2 emoji codes 👍🏻👍 will be considered 2 different emojis

What changes do you think we should make in order to solve the problem?

When we get frequenty use emojis from Onyx, We should delete emojis with duplicate names to get unique names and recalculate the count by adding the other counts together

App/src/libs/EmojiUtils.ts

Line 46 in 109d4aa

.filter((emoji): emoji is FrequentlyUsedEmoji => !!emoji) ?? [];

What alternative solutions did you explore? (Optional)

We should save frequenty use emojis with name, count and lastUpdatedAt to Onyx

Proposal

Please re-state the problem that we are trying to solve in this issue.

emoji is displayed in frequently used every time when change the color

What is the root cause of that problem?

On the AddComment API response, each variant of the same emoji (with different skin tones) is treated as a separate entry due to unique emoji codes for each variant.

Here is the example frequent emoji onyx data in the API response

       {
            "key": "nvp_expensify_frequentlyUsedEmojis",
            "onyxMethod": "set",
            "value": [
                {
                    "code": "\ud83d\ude00",
                    "count": 3,
                    "lastUpdatedAt": 1720716420
                },
                {
                    "code": "\ud83d\udc4d",
                    "count": 2,
                    "lastUpdatedAt": 1720717020
                },
                {
                    "code": "\ud83d\udc4d\ud83c\udffe",
                    "count": 2,
                    "lastUpdatedAt": 1720714440
                },
                {
                    "code": "\ud83d\udc4d\ud83c\udffb",
                    "count": 2,
                    "lastUpdatedAt": 1720714380
                },
                {
                    "code": "\ud83d\ude01",
                    "count": 1,
                    "lastUpdatedAt": 1720714380
                },
                {
                    "code": "\ud83d\ude06",
                    "count": 1,
                    "lastUpdatedAt": 1720714380
                }
            ]
        },

What changes do you think we should make in order to solve the problem?

Merge Duplicate Emojis and ensure to summing their count and use the latest lastUpdatedAt timestamp. Then sort accordingly to ensure the most used emojis are on the left, and if the count sum of 2 or more emojis the same, put the emoji with the latest lastUpdatedAt on the left

Add the following code after this code

        const emojiMap = new Map();

        frequentlyUsedEmojis.forEach((emoji) => {
            if (emojiMap.has(emoji.code)) {
                const existingEmoji = emojiMap.get(emoji.code);
                emojiMap.set(emoji.code, {
                    ...emoji,
                    count: existingEmoji.count + emoji.count,
                    lastUpdatedAt: Math.max(existingEmoji.lastUpdatedAt, emoji.lastUpdatedAt)
                });
            } else {
                emojiMap.set(emoji.code, emoji);
            }
        });

        frequentlyUsedEmojis = Array.from(emojiMap.values()).sort((a, b) => {
            if (a.count !== b.count) {
                return b.count - a.count;
            } else {
                return b.lastUpdatedAt - a.lastUpdatedAt;
            }
        });

Since the response from backend has duplicates this should ideally be fixed from backend.

However, I found another issue here. We are not adding the recently used emojis to the frequently used emojis optimistically. This does not fall directly under the scope of this bug. But we might consider fixing that. This would be a frontend fix.

@marcaaron it looks like you've been all over the AddComment updates recently, do you have time to take a look at this one?

[Beamanator]

OK it looooks like this could have been caused by some recent changes in #42208? (cc @jasperhuangg ) mind taking a look?

[jasperhuangg]

Oh woops, this definitely looks like a regression from my UpdateFrequentlyUsedEmojis performance improvement PRs. I'll look into this. Definitely a back-end bug.

[jasperhuangg]

@c3024 unassigning you since this requires a back-end fix

Hmm I investigated a fix in the back-end, but I don't think it's worth going down that rabbit hole since C++ isn't set up to handle emoji codes well.

I looked over the proposals and think the one from @nyomanjyotisa makes the most sense. Going to go ahead and assign them. Let's make sure to leave some good comments in your PR explaining why we're doing so. Thanks everyone!
