ThemeCache

class in meocord/common Since 4.1.0

class ThemeCache

An app's cache of the themes @MeoCord({ themeFor }) looked up, by server and by user.

Inject it to clear a result once the theme it came from changes, so the next call looks it up again rather than waiting for the result to expire. Each app has its own.

Examples

TypeScript

@Service()
export class GuildSettings {
  readonly themes = new Map<string, ThemeOverride>()

  constructor(private readonly cache: ThemeCache) {}

  setColour(guildId: string, primary: HexColorString) {
    this.themes.set(guildId, { colors: { primary } })
    // The next call in this server looks its theme up again, rather than waiting for ttlSeconds
    this.cache.invalidateGuild(guildId)
  }
}
