Class MemoryProvider

In-memory storage provider backed by Map<string, Uint8Array>.

getSignedUrl returns a deterministic synthetic URL memory://<encoded-key>?expires=<epoch> — non-functional off-process.

Constructors

constructor

new MemoryProvider(now?: () => number): MemoryProvider
Parameters
- now: () => number = ...
  Wall-clock source (epoch ms). Injected by createProvider as runtime.now(); the runtime service is the only sanctioned clock outside packages/runtime. Defaults to () => 0 for direct construction where the synthetic signed-URL expiry is not exercised.
Returns MemoryProvider
- Defined in packages/storage-plugin/src/providers/memory-provider.ts:28

Methods

connect

connect(): Promise<void>
Connect is a no-op for the memory provider.

Returns Promise<void>
Implementation of StorageProvider.connect
- Defined in packages/storage-plugin/src/providers/memory-provider.ts:33

delete

delete(path: string): Promise<boolean>
Deletes an object from memory.
Parameters
- path: string
  Object path/key
Returns Promise<boolean>
true if an object was deleted
Implementation of StorageProvider.delete
- Defined in packages/storage-plugin/src/providers/memory-provider.ts:93

disconnect

disconnect(): Promise<void>
Disconnect is a no-op for the memory provider.

Returns Promise<void>
Implementation of StorageProvider.disconnect
- Defined in packages/storage-plugin/src/providers/memory-provider.ts:39

exists

exists(path: string): Promise<boolean>
Reports whether an object exists in memory.
Parameters
- path: string
  Object path/key
Returns Promise<boolean>
true if present
Implementation of StorageProvider.exists
- Defined in packages/storage-plugin/src/providers/memory-provider.ts:103

get

get(path: string): Promise<Uint8Array<ArrayBufferLike> | null>
Retrieves an object from memory; null when absent.
Parameters
- path: string
  Object path/key
Returns Promise<Uint8Array<ArrayBufferLike> | null>
The object bytes, or null
Implementation of StorageProvider.get
- Defined in packages/storage-plugin/src/providers/memory-provider.ts:82

getSignedUrl

getSignedUrl(path: string, options: { expiresIn: number }): Promise<string>
Returns a synthetic memory:// URL with expiry query parameter.
Parameters
- path: string
  Object path/key
- options: { expiresIn: number }
  Expiry in seconds
Returns Promise<string>
The synthetic signed URL
Implementation of StorageProvider.getSignedUrl
- Defined in packages/storage-plugin/src/providers/memory-provider.ts:114

isHealthy

isHealthy(): Promise<boolean>
M70c: an in-memory store has no backend to be unreachable, so it is always reachable (M47).

Returns Promise<boolean>
true

Since
0.1.0
Implementation of StorageProvider.isHealthy
- Defined in packages/storage-plugin/src/providers/memory-provider.ts:56

isReady

isReady(): boolean
Reports readiness (memory is always ready once connected).

Returns boolean
Implementation of StorageProvider.isReady
- Defined in packages/storage-plugin/src/providers/memory-provider.ts:45

put

put(path: string, data: Uint8Array, _options?: PutObjectOptions): Promise<void>
Stores an object in memory.

Object attributes are ACCEPTED AND NOT PERSISTED: this store holds bytes only and its getSignedUrl produces a synthetic URL nothing fetches, so retaining a content type would be a field no code path reads. Documented per provider in the package README rather than silently dropped.
Parameters
- path: string
  Object path/key
- data: Uint8Array
  Object bytes
- Optional_options: PutObjectOptions
  Accepted for interface parity; see above
Returns Promise<void>
Implementation of StorageProvider.put
- Defined in packages/storage-plugin/src/providers/memory-provider.ts:71
