If you encounter any of those fell free to open an issue in our github repository.

Download

You can download it from npm:

npm i whatsapp-xp

Setting Up

First things first, we include the module into the project.

const Levels = require("whatsapp-xp");

After that, you need to provide a valid mongo database url, and set it. You can do so by:

Levels.setURL("mongodb://..."); // You only need to do this ONCE per process.

Examples - Edited for Whatsapp Bots

Examples assume that you have setted up the module as presented in 'Setting Up' section. Following examples assume that your client is called client.

Following example contains isolated code which you need to integrate in your own command handler.

Following example assumes that you are able to write asynchronous code (use await).

• Allocating Random XP For Each Message Sent

client.on("message", async (message) => {
  if (!message.chat.id) return;
  
  const randomAmountOfXp = Math.floor(Math.random() * 29) + 1; // Min 1, Max 30
  const hasLeveledUp = await Levels.appendXp(message.sender.id, message.chat.id, randomAmountOfXp);
  if (hasLeveledUp) {
    const user = await Levels.fetch(message.sender.id, message.chat.id);
    client.sendTextWithMentions(message.from, `@${message.author}, congratulations! You have leveled up to *${user.level}*. `);
  }
});

• Rank Command

const user = await Levels.fetch(message.sender.id, message.chat.id); // Selects the target from the database.

if (!user) return message.channel.send("Seems like this user has not earned any xp so far."); // If there isnt such user in the database, we send a message in general.

client.sendTextWithMentions(message.from, `> *@${message.author}* is currently level ${user.level}.`); // We show the level.

• Leaderboard Command

const rawLeaderboard = await Levels.fetchLeaderboard(message.chat.id, 10); // We grab top 10 users with most xp in the current server.

if (rawLeaderboard.length < 1) return client.reply(message.from, "Nobody's in leaderboard yet.", message.id);

const leaderboard = await Levels.computeLeaderboard(client, rawLeaderboard); // We process the leaderboard.

const lb = leaderboard.map(e => `${e.position}. @${e.userID.replace('@c.us', '')}\nLevel: ${e.level}\nXP: ${e.xp.toLocaleString()}`); // We map the outputs.

client.sendTextWithMentions(message.from, `*Leaderboard*:\n\n${lb.join("\n\n")}`);

• Output:

Promise<Object>

subtractXp

It removes a specified amount of xp to the current amount of xp for that user, in that guild. It re-calculates the level.

Levels.appendXp(<UserID - String>, <GuildID - String>, <Amount - Integer>);

• Output:

Promise<Boolean/Object>

subtractLevel

It removes a specified amount of levels to current amount, re-calculates and sets the xp reqired to reach the new amount of levels.
