Examples

You can read this example bot on GitHub: giveaways-bot

Launch of the module

const Discord = require('discord.js'),
    client = new Discord.Client(),
    settings = {
        prefix: 'g!',
        token: 'Your Discord Bot Token'
    };

// Requires Manager from discord-giveaways
const { GiveawaysManager } = require('discord-giveaways');
// Starts updating currents giveaways
const manager = new GiveawaysManager(client, {
    storage: './giveaways.json',
    updateCountdownEvery: 10000,
    hasGuildMembersIntent: false,
    default: {
        botsCanWin: false,
        exemptPermissions: ['MANAGE_MESSAGES', 'ADMINISTRATOR'],
        embedColor: '#FF0000',
        embedColorEnd: '#000000',
        reaction: '🎉'
    }
});
// We now have a giveawaysManager property to access the manager everywhere!
client.giveawaysManager = manager;

client.on('ready', () => {
    console.log('I\'m ready!');
});

client.login(settings.token);

After that, giveaways that are not yet completed will start to be updated again and new giveaways can be started. You can pass an options object to customize the giveaways. Here is a list of them:

  • client: the discord client (your discord bot instance).
  • options.storage: the json file that will be used to store giveaways.
  • options.updateCountdownEvery: the number of milliseconds it will take to update the timers.
  • options.endedGiveawaysLifetime: duration for which the ended giveaways remain in the database after they are ended.
  • options.hasGuildMembersIntent: whether the bot has access to the GUILD_MEMBERS intent. It works without, but it will be faster with.
  • options.default.botsCanWin: whether bots can win a giveaway.
  • options.default.exemptPermissions: an array of discord permissions. Members who have at least one of these permissions will not be able to win a giveaway even if they react to it.
  • options.default.embedColor: a hexadecimal color for the embeds of giveaways.
  • options.default.embedColorEnd: a hexadecimal color for the embeds of giveaways when they are ended.
  • options.default.reaction: the reaction that users will have to react to in order to participate.
  • options.default.lastChance: the last chance system parameters. Usage example for the giveaway object

Start a giveaway

client.on('message', (message) => {
    const ms = require('ms'); // npm install ms
    const args = message.content.slice(settings.prefix.length).trim().split(/ +/g);
    const command = args.shift().toLowerCase();

    if (command === 'start-giveaway') {
        // g!start-giveaway 2d 1 Awesome prize!
        // Will create a giveaway with a duration of two days, with one winner and the prize will be "Awesome prize!"

        client.giveawaysManager.start(message.channel, {
            time: ms(args[0]),
            winnerCount: parseInt(args[1]),
            prize: args.slice(2).join(' ')
        }).then((gData) => {
            console.log(gData); // {...} (messageID, end date and more)
        });
        // And the giveaway has started!
    }
});
  • options.time: the giveaway duration.
  • options.prize: the giveaway prize.
  • options.hostedBy: the user who hosts the giveaway.
  • options.winnerCount: the number of giveaway winners.
  • options.winnerIDs: the IDs of the giveaway winners. ⚠ You do not have to and would not even be able to set this as a start option! The array only gets filled when a giveaway ends or is rerolled!
  • options.botsCanWin: whether bots can win the giveaway.
  • options.exemptPermissions: an array of discord permissions. Server members who have at least one of these permissions will not be able to win a giveaway even if they react to it.
  • exemptMembers: function to filter members. If true is returned, the member won't be able to win the giveaway. Usage example
  • options.bonusEntries: an array of BonusEntry objects. Usage example
  • options.embedColor: a hexadecimal color for the embeds of giveaways.
  • options.embedColorEnd: a hexadecimal color the embeds of giveaways when they are ended.
  • options.reaction: the reaction that users will have to react to in order to participate.
  • options.extraData: Extra data which you want to save regarding this giveaway. You can access it from the giveaway object using giveaway.extraData.
  • options.lastChance: the last chance system parameters. Usage example

This allows you to start a new giveaway. Once the start() function is called, the giveaway starts, and you only have to observe the result, the package does the rest!

⚠ ATTENTION!

The command examples below (reroll, edit delete, end) can be executed on any server your bot is a member of if a person has the prize or the messageIDof a giveaway. To prevent abuse we recommend to check if the prize or the messageID that was provided by the command user is for a giveaway on the same server, if it is not, then cancel the command execution.

let giveaway = 
// Search with giveaway prize
client.giveawaysManager.giveaways.find((g) => g.guildID === message.guild.id && g.prize === args.join(' ')) ||
// Search with messageID
client.giveawaysManager.giveaways.find((g) => g.guildID === message.guild.id && g.messageID === args[0]);

// If no giveaway was found
if (!giveaway) return message.channel.send('Unable to find a giveaway for `'+ args.join(' ') +'`.');

Reroll a giveaway

client.on('message', (message) => {
    const args = message.content.slice(settings.prefix.length).trim().split(/ +/g);
    const command = args.shift().toLowerCase();

    if (command === 'reroll') {
        const messageID = args[0];
        client.giveawaysManager.reroll(messageID).then(() => {
            message.channel.send('Success! Giveaway rerolled!');
        }).catch((err) => {
            message.channel.send('No giveaway found for ' + messageID + ', please check and try again');
        });
    }
});
  • options.winnerCount: the number of winners to pick.
  • options.messages: an object with the "congrat" and the "error" message. Usage example

Edit a giveaway

client.on('message', (message) => {
    const args = message.content.slice(settings.prefix.length).trim().split(/ +/g);
    const command = args.shift().toLowerCase();

    if (command === 'edit') {
        const messageID = args[0];
        client.giveawaysManager.edit(messageID, {
            addTime: 5000,
            newWinnerCount: 3,
            newPrize: 'New Prize!'
        }).then(() => {
            // Here, we can calculate the time after which we are sure that the lib will update the giveaway
            const numberOfSecondsMax = client.giveawaysManager.options.updateCountdownEvery / 1000;
            message.channel.send('Success! Giveaway will updated in less than ' + numberOfSecondsMax + ' seconds.');
        }).catch((err) => {
            message.channel.send('No giveaway found for ' + messageID + ', please check and try again');
        });
    }
});
  • options.newWinnerCount: the new number of winners.
  • options.newPrize: the new prize.
  • options.addTime: the number of milliseconds to add to the giveaway duration.
  • options.setEndTimestamp: the timestamp of the new end date (for example, for the giveaway to be ended in 1 hour, set it to Date.now() + 60000).
  • options.newMessages: the new giveaway messages
  • options.newExtraData: the new extra data value for the giveaway
  • options.newBonusEntries: the new BonusEntry objects (for example, to change the amount of entries).

⚠️ Note: to reduce giveaway time, define addTime with a negative number! For example addTime: -5000 will reduce giveaway time by 5 seconds!

Delete a giveaway

client.on('message', (message) => {
    const args = message.content.slice(settings.prefix.length).trim().split(/ +/g);
    const command = args.shift().toLowerCase();

    if (command === 'delete') {
        const messageID = args[0];
        client.giveawaysManager.delete(messageID).then(() => {
            message.channel.send('Success! Giveaway deleted!');
        }).catch((err) => {
            message.channel.send('No giveaway found for ' + messageID + ', please check and try again');
        });
    }
});
  • doNotDeleteMessage: whether the giveaway message shouldn't be deleted.

⚠️ Note: when you use the delete function, the giveaway data and per default the message of the giveaway are deleted. You cannot restore a giveaway once you have deleted it!

End a giveaway

client.on('message', (message) => {
    const args = message.content.slice(settings.prefix.length).trim().split(/ +/g);
    const command = args.shift().toLowerCase();

    if (command === 'end') {
        const messageID = args[0];
        client.giveawaysManager.end(messageID).then(() => {
            message.channel.send('Success! Giveaway ended!');
        }).catch((err) => {
            message.channel.send('No giveaway found for ' + messageID + ', please check and try again');
        });
    }
});

Fetch giveaways

// A list of all the giveaways
const allGiveaways = client.giveawaysManager.giveaways; // [ {Giveaway}, {Giveaway} ]

// A list of all the giveaways on the server with ID "1909282092"
const onServer = client.giveawaysManager.giveaways.filter(g => g.guildID === '1909282092');

// A list of the current active giveaways (not ended)
const notEnded = client.giveawaysManager.giveaways.filter(g => !g.ended);

Exempt Members

client.giveawaysManager.start(message.channel, {
    time: 60000,
    winnerCount: 1,
    prize: 'Free Steam Key',
    // Only members who have the "Nitro Boost" role are able to win
    exemptMembers: (member) => !member.roles.cache.some((r) => r.name === 'Nitro Boost')
})

⚠️ Note: If the function should be customizable

const roleName = 'Nitro Boost';

client.giveawaysManager.start(message.channel, {
    time: 60000,
    winnerCount: 1,
    prize: 'Free Steam Key',
    // Only members who have the the role which is assigned to "roleName" are able to win
    exemptMembers: new Function('member', `return !member.roles.cache.some((r) => r.name === \'${roleName}\')`),
})

Last Chance

client.giveawaysManager.start(message.channel, {
    time: 60000,
    winnerCount: 1,
    prize: 'Discord Nitro!',
    lastChance: {
        enabled: true,
        content: '⚠️ **LAST CHANCE TO ENTER !** ⚠️',
        threshold: 5000,
        embedColor: '#FF0000'
    }
})

Bonus Entries

client.giveawaysManager.start(message.channel, {
    time: 60000,
    winnerCount: 1,
    prize: 'Free Steam Key',
    bonusEntries: [
        // Members who have the "Nitro Boost" role get 2 bonus entries
        {
            bonus: (member) => member.roles.cache.some((r) => r.name === 'Nitro Boost') ? 2 : null,
            cumulative: false
        }
    ]
})

⚠️ Note: If the bonus function should be customizable

const roleName = 'Nitro Boost';
const roleBonusEntries = 2;

client.giveawaysManager.start(message.channel, {
    time: 60000,
    winnerCount: 1,
    prize: 'Free Steam Key',
    bonusEntries: [
        // Members who have the role which is assigned to "roleName" get the amount of bonus entries which are assigned to "roleBonusEntries"
        {   
            bonus: new Function('member', `return member.roles.cache.some((r) => r.name === \'${roleName}\') ? ${roleBonusEntries} : null`),
            cumulative: false 
        }
    ]
})

🇫🇷 Translation

You can also pass a messages parameter for start() function, if you want to translate the bot text:

  • options.messages.giveaway: the message that will be displayed above the embeds.
  • options.messages.giveawayEnded: the message that will be displayed above the embeds when the giveaway is ended.
  • options.messages.timeRemaining: the message that displays the remaining time (the timer).
  • options.messages.inviteToParticipate: the message that invites users to participate.
  • options.messages.winMessage: the message that will be displayed to congratulate the winner(s) when the giveaway is ended.
  • options.messages.embedFooter: the message displayed at the bottom of the embeds.
  • options.messages.noWinner: the message that is displayed if no winner can be drawn.
  • options.messages.winners: simply the word "winner" in your language.
  • options.messages.endedAt: simply the words "Ended at" in your language.
  • options.messages.units.seconds: simply the word "seconds" in your language.
  • options.messages.units.minutes: simply the word "minutes" in your language.
  • options.messages.units.hours: simply the word "hours" in your language.
  • options.messages.units.days: simply the word "days" in your language.

Note: units should be in the plural.

For example:

client.giveawaysManager.start(message.channel, {
    time: ms(args[0]),
    winnerCount: parseInt(args[1]),
    prize: args.slice(2).join(' '),
    messages: {
        giveaway: '@everyone\n\n🎉🎉 **GIVEAWAY** 🎉🎉',
        giveawayEnded: '@everyone\n\n🎉🎉 **GIVEAWAY ENDED** 🎉🎉',
        timeRemaining: 'Time remaining: **{duration}**',
        inviteToParticipate: 'React with 🎉 to participate!',
        winMessage: 'Congratulations, {winners}! You won **{prize}**!\n{messageURL}',
        embedFooter: 'Powered by the discord-giveaways package',
        noWinner: 'Giveaway cancelled, no valid participations.',
        hostedBy: 'Hosted by: {user}',
        winners: 'winner(s)',
        endedAt: 'Ended at',
        units: {
            seconds: 'seconds',
            minutes: 'minutes',
            hours: 'hours',
            days: 'days',
            pluralS: false // Not needed, because units end with a S so it will automatically removed if the unit value is lower than 2
        }
    }
});

And for the reroll() function:

client.giveawaysManager.reroll(messageID, {
        messages: {
            congrat: ':tada: New winner(s): {winners}! Congratulations, you won **{prize}**!\n{messageURL}',
            error: 'No valid participations, no new winner(s) can be chosen!'
        }
    }).catch((err) => {
        message.channel.send('No giveaway found for ' + messageID + ', please check and try again');
    });
  • options.messages.congrat: the congratulatory message.
  • options.messages.error: the error message if there is no valid participant.

Custom Database

You can use your custom database to save giveaways, instead of the json files (the "database" by default for discord-giveaways). For this, you will need to extend the GiveawaysManager class, and replace some methods with your custom ones. There are 4 methods you will need to replace:

  • getAllGiveaways: this method returns an array of stored giveaways.
  • saveGiveaway: this method stores a new giveaway in the database.
  • editGiveaway: this method edits a giveaway already stored in the database.
  • deleteGiveaway: this method deletes a giveaway from the database (permanently).

⚠️ All the methods should be asynchronous to return a promise!

Here is an example, using quick.db, a SQLite database. The comments in the code below are very important to understand how it works!

Other examples:

const Discord = require('discord.js'),
    client = new Discord.Client(),
    settings = {
        prefix: 'g!',
        token: 'Your Discord Bot Token'
    };

// Load quick.db - it's an example of custom database, you can use MySQL, PostgreSQL, etc...
const db = require('quick.db');
if (!Array.isArray(db.get('giveaways'))) db.set('giveaways', []);

const { GiveawaysManager } = require('discord-giveaways');
const GiveawayManagerWithOwnDatabase = class extends GiveawaysManager {
    // This function is called when the manager needs to get all giveaways which are stored in the database.
    async getAllGiveaways() {
        // Get all giveaways from the database
        return db.get('giveaways');
    }

    // This function is called when a giveaway needs to be saved in the database.
    async saveGiveaway(messageID, giveawayData) {
        // Add the new giveaway to the database
        db.push('giveaways', giveawayData);
        // Don't forget to return something!
        return true;
    }

    // This function is called when a giveaway needs to be edited in the database.
    async editGiveaway(messageID, giveawayData) {
        // Get all giveaways from the database
        const giveaways = db.get('giveaways');
        // Remove the unedited giveaway from the array
        const newGiveawaysArray = giveaways.filter((giveaway) => giveaway.messageID !== messageID);
        // Push the edited giveaway into the array
        newGiveawaysArray.push(giveawayData);
        // Save the updated array
        db.set('giveaways', newGiveawaysArray);
        // Don't forget to return something!
        return true;
    }

    // This function is called when a giveaway needs to be deleted from the database.
    async deleteGiveaway(messageID) {
        // Get all giveaways from the database
        const giveaways = db.get('giveaways');
        // Remove the giveaway from the array
        const newGiveawaysArray = giveaways.filter((giveaway) => giveaway.messageID !== messageID);
        // Save the updated array
        db.set('giveaways', newGiveawaysArray);
        // Don't forget to return something!
        return true;
    }
};

// Create a new instance of your new class
const manager = new GiveawayManagerWithOwnDatabase(client, {
    updateCountdownEvery: 10000,
    default: {
        botsCanWin: false,
        exemptPermissions: ['MANAGE_MESSAGES', 'ADMINISTRATOR'],
        embedColor: '#FF0000',
        embedColorEnd: '#000000',
        reaction: '🎉'
    }
});
// We now have a giveawaysManager property to access the manager everywhere!
client.giveawaysManager = manager;

client.on('ready', () => {
    console.log('I\'m ready!');
});

client.login(settings.token);

Support shards

To make discord-giveaways-v13 working with shards, you will need to extend the GiveawaysManager class and update the refreshStorage() method. This method should call the getAllGiveaways() method for every shard, so all GiveawaysManager synchronize their cache with the updated database.

const Discord = require('discord.js'),
    client = new Discord.Client(),
    settings = {
        prefix: 'g!',
        token: 'Your Discord Bot Token'
    };

// Extends the GiveawaysManager class and update the refreshStorage method
const { GiveawaysManager } = require('discord-giveaways');
const GiveawayManagerWithShardSupport = class extends GiveawaysManager {
    // Refresh storage method is called when the database is updated on one of the shards
    async refreshStorage() {
        // This should make all shard refreshing their cache with the updated database
        return client.shard.broadcastEval(() => this.giveawaysManager.getAllGiveaways());
    }
};

// Create a new instance of your new class
const manager = new GiveawayManagerWithShardSupport(client, {
    storage: './storage.json',
    updateCountdownEvery: 10000,
    default: {
        botsCanWin: false,
        exemptPermissions: ['MANAGE_MESSAGES', 'ADMINISTRATOR'],
        embedColor: '#FF0000',
        embedColorEnd: '#000000',
        reaction: '🎉'
    }
});
// We now have a giveawaysManager property to access the manager everywhere!
client.giveawaysManager = manager;

client.on('ready', () => {
    console.log('I\'m ready!');
});

client.login(settings.token);
