# Setting Up
First things first, we include the module into the project.
```js
const Levels = require("discord-xp");
```
After that, you need to provide a valid mongo database url, and set it. You can do so by:
```js
Levels.setURL("mongodb://..."); // You only need to do this ONCE per process.
```

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

*Following examples assume that your `client.on("message", message` is called `message`.*

*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**

```js
client.on("message", async (message) => {
  if (!message.guild) return;
  if (message.author.bot) return;
  
  const randomAmountOfXp = Math.floor(Math.random() * 29) + 1; // Min 1, Max 30
  const hasLeveledUp = await Levels.appendXp(message.author.id, message.guild.id, randomAmountOfXp);
  if (hasLeveledUp) {
    const user = await Levels.fetch(message.author.id, message.guild.id);
    message.channel.send(`${message.author}, congratulations! You have leveled up to **${user.level}**. :tada:`);
  }
});
```

- **Rank Command**

```js
const target = message.mentions.users.first() || message.author; // Grab the target.

const user = await Levels.fetch(target.id, message.guild.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.

message.channel.send(`> **${target.tag}** is currently level ${user.level}.`); // We show the level.
```

- **Leaderboard Command**

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

if (rawLeaderboard.length < 1) return reply("Nobody's in leaderboard yet.");

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

const lb = leaderboard.map(e => `${e.position}. ${e.username}#${e.discriminator}\nLevel: ${e.level}\nXP: ${e.xp.toLocaleString()}`); // We map the outputs.

message.channel.send(`**Leaderboard**:\n\n${lb.join("\n\n")}`);
```

- **Position of a user in the leaderboard**
```js
const target = message.mentions.users.first() || message.author; // Grab the target.

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

console.log(user.position);
```

- **Canvacord Integration**

Obviously you need the npm package `canvacord` for that. Install it with `npm install canvacord`.

```js
const canvacord = require('canvacord');

const target = message.mentions.users.first() || message.author; // Grab the target.

    const user = await Levels.fetch(target.id, message.guild.id, true); // Selects the target from the database.
    
    const rank = new canvacord.Rank() // Build the Rank Card
        .setAvatar(target.displayAvatarURL({format: 'png', size: 512}))
        .setCurrentXP(user.xp) // Current User Xp
        .setRequiredXP(Levels.xpFor(user.level + 1)) // We calculate the required Xp for the next level
        .setRank(user.position) // Position of the user on the leaderboard
        .setLevel(user.level) // Current Level of the user
        .setStatus(target.presence.status)
        .setProgressBar("#FFFFFF")
        .setUsername(target.username)
        .setDiscriminator(target.discriminator);

    rank.build()
        .then(data => {
        const attachment = new Discord.MessageAttachment(data, "RankCard.png");
        message.channel.send(attachment);
    });
```
