Add and remove reactions to every message on a channel

[toastyy00]

Can I react chat from the old chat until recently on a specific channel?

Using the code example from the README.
Supports multiple reactions, scans all messages from the last

To add reaction(s), use let reactionFn = api.addReaction
To delete reaction(s), use let reactionFn = api.deleteReaction

Stop with loop = false

{
  id()
  let channelId = cid
  let amount = 99999999
  let delayMs = 500
  let reactions = ['🤔', '🔥']
  let reactionFn = api.addReaction // or api.deleteReaction

  let beforeMessageId = '8999999999999999999' // Leave it like this to react from latest

  let count = 0
  var loop = true
  while (loop) {
    const messages = await api.getMessages(channelId, 100, { before: beforeMessageId })

    // We reached the start of the conversation
    if (messages.length < 100 && messages.filter(x => x.type === 0 || x.type === 19).length === 0) {
      loop = false
      console.log(`[${count}/${amount}] Reached the start of the conversations! Ending.`)
      continue
    }

    // Update last message snowflake for next iteration
    beforeMessageId = messages[0].id

    for (const aMessage of messages) {
      if (loop === false) break

      // Check if the max amount was reached
      if (count >= amount) {
        loop = false
        console.log(`[${count}/${amount}] Reacted the requested amount of messages! Ending.`)
        break
      }

      // Update last message snowflake for next iteration
      beforeMessageId = aMessage.id

      // Check if the message should be reacted
      if (aMessage.type === 0 || aMessage.type === 19) {
        for (const reaction of reactions) {
          await reactionFn(channelId, aMessage.id, reaction)
          await delay(delayMs)
        }

        count++
        console.log(`[${count}/${amount}] Treated a message! ID=${aMessage.id}`)
        if (count < amount) await delay(delayMs)
      }
    }
    await delay(delayMs)
  }
}
