Parameters

Parameter	Type
`synapse`	`Synapse`
`warmStorageService`	`WarmStorageService`
`pieceRetriever`	`PieceRetriever`
`withCDN`	`boolean`

Methods

createContext()

createContext(options?): Promise<StorageContext>;

Defined in: packages/synapse-sdk/src/storage/manager.ts:363

Create a new storage context with specified options

Parameters

Parameter	Type
`options?`	`StorageServiceOptions`

Returns

Promise<StorageContext>

createContexts()

createContexts(options?): Promise<StorageContext[]>;

Defined in: packages/synapse-sdk/src/storage/manager.ts:300

Creates storage contexts for multi-provider storage deals and other operations.

By storing data with multiple independent providers, you reduce dependency on any single provider and improve overall data availability. Use contexts together as a group.

Contexts are selected by priority:

Specified datasets (dataSetIds) - uses their existing providers
Specified providers (providerIds or providerAddresses) - finds or creates matching datasets
Automatically selected from remaining approved providers

For automatic selection, existing datasets matching the metadata are reused unless forceCreateDataSets is true. Providers are randomly chosen to distribute across the network.

Parameters

Parameter	Type	Description
`options?`	`CreateContextsOptions`	Configuration options

Returns

Promise<StorageContext[]>

Promise resolving to array of storage contexts

download()

download(pieceCid, options?): Promise<Uint8Array<ArrayBufferLike>>;

Defined in: packages/synapse-sdk/src/storage/manager.ts:192

Download data from storage If context is provided, routes to context.download() Otherwise performs SP-agnostic download

Parameters

Parameter	Type
`pieceCid`	`string` \| `PieceLink`
`options?`	`StorageManagerDownloadOptions`

Returns

Promise<Uint8Array<ArrayBufferLike>>

findDataSets(clientAddress?): Promise<EnhancedDataSetInfo[]>;

Defined in: packages/synapse-sdk/src/storage/manager.ts:441

getDefaultContext()

getDefaultContext(): Promise<StorageContext>;

Defined in: packages/synapse-sdk/src/storage/manager.ts:432
