discord.js - Imagine a bot•9mo ago

Reading reaction info

I am attempting to take an array of reactions on a given message and identify the individual users that have posted each reaction. I have run into an issue where I can only reliably console.log the bot's user ID, and the list does not contain the rest of the user IDs unless the command is run immediately following a reaction state change (someone adds one). The other issue I'm running into is that I can console.log the information, but I can't seem to access it programmatically. This line of code is turning the reaction.users circular collection into something I can read in the console.

reactions.forEach(reaction => { if (reaction.count>1) { console.log(JSON.stringify(reaction.users,null,2)); } });

reactions.forEach(reaction => { if (reaction.count>1) { console.log(JSON.stringify(reaction.users,null,2)); } });

Before that line is stringifying the array, this block is trying to read each element of the reactions.users array and console log it:

let userIds= [];
        for (const user in reactions.users) {
            userIds.push(user);
        }
        console.log(`Ids: ${userIds}`);

let userIds= [];
        for (const user in reactions.users) {
            userIds.push(user);
        }
        console.log(`Ids: ${userIds}`);

This is not working. The console log is returning a list of userIDs in the stringified log, but returning Id: for the block that is trying to get the user IDs. I am not sure what to do or try next, as I've already dug through youtube, guides, and chatGPT

what does reaction.users.cache.size return

Requiem•9mo ago

no errors?

lexitoriusOP•9mo ago

I will check on mark’s question in a bit But yeah it’s not throwing any errors, just returning an empty list

d.js docs•9mo ago

Documentation suggestion for @lexitorius: :method: ReactionUserManager#fetch() Fetches all the users that gave this reaction. Resolves with a collection of users, mapped by their ids.

Bloonatics•9mo ago

you may need to fetch the users

There's more above but not super related reactions is an array of the reaction objects

Bloonatics•9mo ago

this won't work if you're fetching older messages (not cached), you need to fetch the users https://discord.com/channels/222078108977594368/1210680446740992121/1210790135990460426
