CreateContextsOptions

Defined in: packages/synapse-sdk/src/types.ts:358

Options for creating multiple storage contexts via createContexts()

Extends BaseContextOptions with plural provider/dataset selection and count for multi-provider redundancy.

Provider targeting is mutually exclusive, use ONE of:

  • providerIds to target specific providers (SDK handles dataset resolution)
  • dataSetIds to target specific existing datasets
  • Neither, to let the SDK auto-select providers

copies?

Section titled “copies?”

optional copies?: number

Defined in: packages/synapse-sdk/src/types.ts:360

Number of storage copies to create (optional, defaults to 2)

dataSetIds?

Section titled “dataSetIds?”

optional dataSetIds?: bigint[]

Defined in: packages/synapse-sdk/src/types.ts:370

Specific data set IDs to target. Each must be an active data set owned by the caller. Mutually exclusive with providerIds.

Use this only when resuming into a known data set from a prior operation. For first-time uploads to specific providers, use providerIds instead, the SDK handles data set creation automatically.

excludeProviderIds?

Section titled “excludeProviderIds?”

optional excludeProviderIds?: bigint[]

Defined in: packages/synapse-sdk/src/types.ts:388

Do not select any of these providers

metadata?

Section titled “metadata?”

optional metadata?: Record<string, string>

Defined in: packages/synapse-sdk/src/types.ts:341

Custom metadata for data sets (key-value pairs). Used to match existing data sets during provider selection.

providerIds?

Section titled “providerIds?”

optional providerIds?: bigint[]

Defined in: packages/synapse-sdk/src/types.ts:385

Specific provider IDs to upload to. The SDK resolves or creates data sets on each provider automatically. Mutually exclusive with dataSetIds.

This is the recommended way to target specific providers. Do not call createContext() to resolve data sets first, pass provider IDs here and the SDK handles the rest.

Example

Section titled “Example”
await synapse.storage.upload(data, { providerIds: [4n, 9n] })

withCDN?

Section titled “withCDN?”

optional withCDN?: boolean
