constructor

new LuxarZipStore(url: string): LuxarZipStore
Parameters
- url: string
Returns LuxarZipStore
- Defined in src/data/zip/store.ts:124

Properties

`Private` `Readonly`url

url: string

Methods

probeIdentity

probeIdentity(signal?: AbortSignal, timeoutMs?: number): Promise<string | null>
Fresh identity of the archive, delegated to the reader so the HEAD it costs also seeds the length ZipFileStore would otherwise ask for separately.
Parameters
- Optionalsignal: AbortSignal
- OptionaltimeoutMs: number
Returns Promise<string | null>
- Defined in src/data/zip/store.ts:133

get

get(
    key: string,
    signal?: AbortSignal | GetOptions,
    options?: ChunkSourceGetOptions,
): Promise<Uint8Array<ArrayBufferLike> | undefined>
Read one member with ONE ranged GET (header + payload, sized from the central directory) instead of unzipit's two serial ones.
Parameters
- key: string
- Optionalsignal: AbortSignal | GetOptions
  Cancels this member's window fetch, queued or in flight (the store's own lifetime still cancels it too). zarrita, which also reads this store directly, passes its GetOptions here instead. The shared directory open never takes it: one cancelled chunk must not fail the directory every other chunk needs.
- Optionaloptions: ChunkSourceGetOptions
  priority classes the member's window fetch in the gate.
Returns Promise<Uint8Array<ArrayBufferLike> | undefined>

has

has(key: string): Promise<boolean>
Parameters
- key: string
Returns Promise<boolean>
- Defined in src/data/zip/store.ts:225

dispose

dispose(): void
Drop the archive. The directory is not reusable afterwards; a disposed store refuses to re-open rather than quietly starting a fresh download for a dataset the caller has already navigated away from.

Returns void
