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('npg-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);
⚠ 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 messageID
of 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');
});
}
});
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).
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.
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')
})
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 === \'${roleName}\')`),
})
Last Chance
client.giveawaysManager.start(message.channel, {
time: 60000,
winnerCount: 1,
prize: 'Discord Nitro!',
lastChance: {
enabled: true,
content: '⚠️ **LAST CHANCE TO ENTER !** ⚠️',
threshold: 5000,
embedColor: '#FF0000'
}
})
Bonus Entries
client.giveawaysManager.start(message.channel, {
time: 60000,
winnerCount: 1,
prize: 'Free Steam Key',
bonusEntries: [
// Members who have the "Nitro Boost" role get 2 bonus entries
{
bonus: (member) => member.roles.cache.some((r) => r.name === 'Nitro Boost') ? 2 : null,
cumulative: false
}
]
})
bonus
function should be customizable
const roleName = 'Nitro Boost';
const roleBonusEntries = 2;
client.giveawaysManager.start(message.channel, {
time: 60000,
winnerCount: 1,
prize: 'Free Steam Key',
bonusEntries: [
// Members who have the role which is assigned to "roleName" get the amount of bonus entries which are assigned to "roleBonusEntries"
{
bonus: new Function('member', `return member.roles.cache.some((r) => r.name === \'${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).
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:
- MySQL
- MongoDB
- Mongoose
-
QuickMongo
⚠️ Not recommended for high giveaway usage, use themongoose
example instead
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('npg-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
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('npm-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);
