alt

• get alt(): undefined | string

• Gets the NIP-31 "alt" tag of the event.

  Returns undefined | string
• set alt(alt: undefined | string): void

• Sets the NIP-31 "alt" tag of the event. Use this to set an alt tag so clients that don't handle a particular event kind can display something useful for users.

  Parameters

  • alt: undefined | string

  Returns void

author

• get author(): NDKUser

• Returns an NDKUser for the author of the event.

  Returns NDKUser
• set author(user: NDKUser): void

• Parameters

  • user: NDKUser

  Returns void

dTag

• get dTag(): undefined | string

• Gets the NIP-33 "d" tag of the event.

  Returns undefined | string
• set dTag(value: undefined | string): void

• Sets the NIP-33 "d" tag of the event.

  Parameters

  • value: undefined | string

  Returns void

isValid

• get isValid(): boolean

• Checks whether the event is valid per underlying NIPs.

  This method is meant to be overridden by subclasses that implement specific NIPs to allow the enforcement of NIP-specific validation rules.

  Returns boolean

deduplicationKey

• deduplicationKey(): string

• Provides a deduplication key for the event.

  For kinds 0, 3, 10k-20k this will be the event : For kinds 30k-40k this will be the event :: For all other kinds this will be the event id

  Returns string

delete

• delete(reason?: string, publish?: boolean): Promise<NDKEvent>

• Generates a deletion event of the current event

  Parameters

  • Optional reason: string

    The reason for the deletion

  • publish: boolean = true

    Whether to publish the deletion event automatically

  Returns Promise<NDKEvent>

  The deletion event

filter

• filter(): NDKFilter

• Provides the filter that will return matching events for this event.

  Returns NDKFilter

  The filter that will return matching events for this event

  Example

  event = new NDKEvent(ndk, { kind: 30000, pubkey: 'pubkey', tags: [ ["d", "d-code"] ] });
     event.filter(); // { "#a": ["30000:pubkey:d-code"] }
  Copy

  Example

  event = new NDKEvent(ndk, { kind: 1, pubkey: 'pubkey', id: "eventid" });
     event.filter(); // { "#e": ["eventid"] }
  Copy

generateTags

• generateTags(): Promise<ContentTag>

• Generates tags for users, notes, and other events tagged in content. Will also generate random "d" tag for parameterized replaceable events where needed.

  Returns Promise<ContentTag>

muted

• muted(): null | string

• Returns null | string

publish

• publish(relaySet?: NDKRelaySet, timeoutMs?: number): Promise<Set<NDKRelay>>

• Attempt to sign and then publish an NDKEvent to a given relaySet. If no relaySet is provided, the relaySet will be calculated by NDK.

  Parameters

  • Optional relaySet: NDKRelaySet

    {NDKRelaySet} The relaySet to publish the even to.

  • Optional timeoutMs: number

  Returns Promise<Set<NDKRelay>>

  A promise that resolves to the relays the event was published to.

rawEvent

• rawEvent(): NostrEvent

• Returns the event as is.

  Returns NostrEvent

  Returns Promise<NDKEvent>

referenceTags

• referenceTags(marker?: string, skipAuthorTag?: boolean): NDKTag[]

• Get the tags that can be used to reference this event from another event

  Parameters

  • Optional marker: string

    The marker to use in the tag

  • Optional skipAuthorTag: boolean

  Returns NDKTag[]

  The NDKTag object referencing this event

  Example

  event = new NDKEvent(ndk, { kind: 30000, pubkey: 'pubkey', tags: [ ["d", "d-code"] ] });
      event.referenceTags(); // [["a", "30000:pubkey:d-code"], ["e", "parent-id"]]
  
      event = new NDKEvent(ndk, { kind: 1, pubkey: 'pubkey', id: "eventid" });
      event.referenceTags(); // [["e", "parent-id"]]
  Copy
