## Features
|
|
|
|
Discordeno is actively maintained to guarantee **excellent performance and ease.**
|
|
|
|
- **Simple, Efficient, and Lightweight**: Discordeno is lightweight, simple to use, and adaptable. By default, no
|
|
caching.
|
|
- **Functional API**: The functional API eliminates the challenges of extending built-in classes and inheritance while
|
|
ensuring overall simple but performant code.
|
|
- **Cross Runtime**: Supports the Node.js and Deno runtimes.
|
|
- **Standalone components**: Discordeno offers the option to have practically any component of a bot as a separate
|
|
piece, including standalone REST, gateways, custom caches, and more.
|
|
- **Plugins:** Designed to allow you to overwrite any portion of the code with your own code. Never go through the
|
|
hassle of maintaining your fork in order to acquire something that is specifically tailored to your requirements.
|
|
Plugins may be used for nearly anything; for instance, we have a few authorised plugins.
|
|
|
|
- A caching plugin that makes anything cacheable.
|
|
- A plugin for sweepers that allows them to periodically clear the cache.
|
|
- The permission plugin internally verifies any missing permissions before sending a call to the Discord API to
|
|
prevent the client from receiving a Discord global ban.
|
|
|
|
- **Flexibility:** You may easily delete an object's attributes if your bot doesn't require them. For instance, you
|
|
shouldn't be required to keep `Channel.topic` if your bot doesn't require it. You may save GBs of RAM in this way. A
|
|
few lines of code are all that are needed to accomplish this for any property on any object.
|
|
|
|
### REST
|
|
|
|
- Freedom from 1 hour downtimes due to invalid requests
|
|
- By lowering the maximum downtime to 10 minutes, Discordeno will prevent your bot from being down for an hour.
|
|
- Freedom from global rate limit errors
|
|
- As your bot grows, you want to handle global rate limits better. Shards don't communicate fast enough to truly
|
|
handle it properly so this allows 1 rest handler across the entire bot.
|
|
- You may really run numerous instances of your bot on different hosts, all of which will connect to the same REST
|
|
server.
|
|
- REST does not rest!
|
|
- Separate rest guarantees that your queued requests will continue to be processed even if your bot breaks for
|
|
whatever reason.
|
|
- Seamless updates! There's a chance you'll lose a lot of messages or replies that are waiting to be given when you
|
|
wish to update and restart the bot. You may restart your bot using this technique and never have to worry about
|
|
losing any answers.
|
|
- Single source of contact to Discord API
|
|
- As a result, you will be able to send requests to Discord from any location, even a bot dashboard. You are no longer
|
|
need to interact with your bot processes in order to submit a request or do anything else. Your bot process should
|
|
be freed up to handle bot events.
|
|
- Scalability! Scalability! Scalability!
|
|
|
|
### Gateway
|
|
|
|
- **Zero Downtime Updates:**
|
|
- A few seconds are needed to update your bot. When using conventional sharding, you must restart in addition to going
|
|
through a 1/5s rate-limited process of identifying all of your shards. As WS processing has been relocated to a
|
|
proxy process, you may resume the bot code right away without worrying about any delays. Normally, if you had a bot
|
|
that was spread across 200,000 servers, restarting it after making a simple modification would take 20 minutes.
|
|
- **Zero Downtime Resharding:**
|
|
- At various periods in time, Discord stops allowing your bot to be added to new servers. Consider 150 shards
|
|
operating on 150,000 servers, for instance. Your shards may support a maximum of 150 \* 2500 = 375,000 servers. Your
|
|
bot will be unable to join new servers once it reaches this point until it re-shards.
|
|
- DD proxy provides 2 types of re-sharding. Automated and manual. You can also have both.
|
|
- Automated: This system will automatically begin a Zero-downtime resharding process behind the scenes when you
|
|
reach 80% of your maximum servers allowed by your shards. For example, since 375,000 was the max, at 300,000 we
|
|
would begin re-sharding behind the scenes with ZERO DOWNTIME.
|
|
- 80% of maximum servers reached (The % of 80% is customizable.)
|
|
- Identify limits have room to allow re-sharding. (Also customizable)
|
|
- Manual: You can also trigger this manually should you choose.
|
|
- **Horizontal Scaling:**
|
|
- The bot may be scaled horizontally thanks to the proxy mechanism. When your business grows significantly, you have
|
|
two options: you can either keep investing money to upgrade your server or you may expand horizontally by purchasing
|
|
numerous more affordable servers. The proxy enables WS handling on a totally other system.
|
|
- **No Loss Restarts:**
|
|
- Without the proxy mechanism, you would typically lose numerous events while restarting a bot. Users could issue
|
|
instructions or send messages that are not screened. As your bot population increases, this amount grows sharply.
|
|
Users who don't receive the automatic roles or any other activities your bot should do may join. You may keep
|
|
restarting your bot thanks to the proxy technology without ever losing any events. While your bot is unavailable,
|
|
events will be added to a queue (the maximum size of the queue is configurable), and once the bot is back online,
|
|
the queue will start processing all of the events.
|
|
- **Controllers:**
|
|
- You have complete control over everything inside the proxy thanks to the controller aspect. To simply override the
|
|
handler, you may supply a function. For instance, you may simply give a method to override a specific function if
|
|
you want it to behave differently rather than forking and maintaining your fork.
|
|
- **Clustering With Workers:**
|
|
- Utilize all of your CPU cores to their greatest potential by distributing the workload across employees. To enhance
|
|
efficiency, manage how many employees and shards there are each worker!
|
|
|
|
### Custom Cache
|
|
|
|
Have your cache setup in any way you like. Redis, PGSQL or any cache layer you would like.
|
|
|
|
## Getting Started
|
|
|
|
### Minimal Example
|
|
|
|
Here is a minimal example to get started with:
|
|
|
|
```typescript
|
|
import {
|
|
createBot,
|
|
Intents,
|
|
startBot,
|
|
} from "https://deno.land/x/discordeno@13.0.0/mod.ts";
|
|
|
|
const bot = createBot({
|
|
token: process.env.DISCORD_TOKEN,
|
|
intents: Intents.Guilds | Intents.GuildMessages,
|
|
events: {
|
|
ready() {
|
|
console.log("Successfully connected to gateway");
|
|
},
|
|
},
|
|
});
|
|
|
|
// Another way to do events
|
|
bot.events.messageCreate = function (b, message) {
|
|
// Process the message here with your command handler.
|
|
};
|
|
|
|
await startBot(bot);
|
|
```
|
|
|
|
