Parameters

guildIds

BigString[]

The guilds to get the sounds from

Returns

Promise<void>

Remarks

Fires a Soundboard Sounds gateway event.

⚠️ Discord will send the Soundboard Sounds for each of the guild ids however you may not receive the same number of events as the ids passed to Request Soundboard Sounds for one of the following reasons:

• The bot is not in the server provided
• The shard the message has been sent from does not receive events for the specified guild

To avoid this Discordeno will automatically try to group the ids based on what shard they will need to be sent, but this involves sending multiple messages in multiple shards

See

https://discord.com/developers/docs/topics/gateway-events#request-soundboard-sounds

---

resharding

resharding: object & object

Defined in: gateway/src/manager.ts:712

Everything related to resharding.

Type Declaration

checkInterval

checkInterval: number

The interval in milliseconds, of how often to check whether resharding is needed and reshard automatically. Set to -1 to disable auto resharding.

Default

28800000 (8 hours)

enabled

enabled: boolean

Whether or not automated resharding should be enabled.

Default

true

getSessionInfo()?

optional getSessionInfo: () => Promise<{ sessionStartLimit: { maxConcurrency: number; remaining: number; resetAfter: number; total: number; }; shards: number; url: string; }>

Handler to get shard count and other session info.

Returns

Promise<{ sessionStartLimit: { maxConcurrency: number; remaining: number; resetAfter: number; total: number; }; shards: number; url: string; }>

shardsFullPercentage

shardsFullPercentage: number

The % of how full a shard is when resharding should be triggered.

Remarks

We use discord recommended shard value to get an approximation of the shard full percentage to compare with this value so the bot may not reshard at the exact percentage provided but may reshard when it is a bit higher than the provided percentage. For accurate calculation, you may override the checkIfReshardingIsNeeded function

Default

80 as in 80%

updateGuildsShardId()?

optional updateGuildsShardId: (guildIds, shardId) => Promise<void>

Handler to edit the shard id on any cached guilds.

Parameters

guildIds

string[]

shardId

number

Returns

Promise<void>

Type Declaration

checkIfReshardingIsNeeded()

checkIfReshardingIsNeeded: () => Promise<{ info?: { sessionStartLimit: { maxConcurrency: number; remaining: number; resetAfter: number; total: number; }; shards: number; url: string; }; needed: boolean; }>

Handler to check if resharding is necessary.

Returns

Promise<{ info?: { sessionStartLimit: { maxConcurrency: number; remaining: number; resetAfter: number; total: number; }; shards: number; url: string; }; needed: boolean; }>

checkIntervalId?

optional checkIntervalId: Timeout

The interval id of the check interval. This is used to clear the interval when the manager is shutdown.

onReshardingSwitch()

onReshardingSwitch: () => Promise<void>

Handle called when all the workers have finished preparing for the resharding.

This should make the new resharded shards become the active ones and shutdown the old ones

Returns

Promise<void>

reshard()

reshard: (info) => Promise<void>

Handler to begin resharding.

Parameters

info

object & object

Returns

Promise<void>

Remarks

This function will resolve once the resharding is done. So when all the calls to tellWorkerToPrepare and onReshardingSwitch are done.

shards

shards: Map<number, DiscordenoShard>

Holds the shards that resharding has created. Once resharding is done, this replaces the gateway.shards

tellWorkerToPrepare()

tellWorkerToPrepare: (workerId, shardId, bucketId) => Promise<void>

Handler to communicate to a worker that it needs to spawn a new shard and identify it for the resharding.

Parameters

workerId

number

shardId

number

bucketId

number

Returns

Promise<void>

Remarks

This handler works in the same way as the tellWorkerToIdentify handler. So you should wait for the worker to have identified the shard before resolving the promise

Overrides

CreateGatewayManagerOptions.resharding

shards: Map<number, DiscordenoShard>

Defined in: gateway/src/manager.ts:708

The shards that are created.

---

shardsPerWorker

shardsPerWorker: number

Inherited from

CreateGatewayManagerOptions.spawnShardDelay

---

spawnShards()

spawnShards: () => Promise<void>

Defined in: gateway/src/manager.ts:749

Start identifying all the shards.

Returns

Promise<void>

---

spreadShardsInRoundRobin

spreadShardsInRoundRobin: boolean

Defined in: gateway/src/manager.ts:599

Whether to spread shards across workers in a round-robin manner.

Remarks

By default, shards are assigned to workers in contiguous blocks based on shardsPerWorker. If any shard is left over, it will be assigned to the last worker. This means that if you have 3 workers and 40 shards while shardsPerWorker is 10, the first worker will get shards 0-9, the second worker will get shards 10-19, and so on, the last worker will get shards 20-39.

If this option is set to true, the shards will be assigned in a round-robin manner to spread more evenly across workers. For example, with 3 workers and 40 shards, the first shard will go to worker 0, the second shard to worker 1, the third shard to worker 2, the fourth shard to worker 0, and so on.

Default

false

Inherited from

CreateGatewayManagerOptions.spreadShardsInRoundRobin

---

Remarks

This should wait for the worker to have identified the shard before resolving the returned promise
