FileBinary

@webda/fs

Class: FileBinary<T>

Defined in: fs/src/filebinary.service.ts:99

FileBinary handles the storage of binary on a hard drive

The structure used for now is /folder/{hash}/data /folder/{hash}/{model}{attribute}{uuid} usage markers /folder/{hash}/proof_{challenge} proof of possession, written by the service on upload

Before 4.0.0-beta.5 the proof was _{challenge} and the challenge was sent to clients: those markers are ignored (a leaked value attaches nothing), the content is uploaded once more to get a proof_ marker.

It takes one parameter folder: "path"

Properties​

_compiledCapabilities​

protected _compiledCapabilities: Record<string, any>

Defined in: core/lib/services/iservice.d.ts:39

Capabilities detected at compile-time from @WebdaCapability-tagged interfaces.

Populated during Service.resolve by reading the service's entry in webda.module.json. Each key is a capability name (e.g., "request-filter"), and the value is an empty object {} by default. Override getCapabilities to provide capability-specific configuration or to conditionally disable capabilities.

loadCapabilities()​

protected loadCapabilities(): void

Defined in: core/lib/services/service.d.ts:120

Fails silently if the application is not available (e.g., in unit tests where services are instantiated without a full application context).

Returns​

void

Example​

// If webda.module.json contains:
// { "moddas": { "MyApp/HawkService": { "capabilities": ["request-filter", "cors-filter"] } } }
// Then after resolve(), this.getCapabilities() returns:
// { "request-filter": {}, "cors-filter": {} }

putRedirectUrl()​

putRedirectUrl(object, attribute, info?, context?): Promise<{ method: string; url: string; }>

Defined in: fs/src/filebinary.service.ts:357

Challenge: the client announces {hash, challenge, ...}; the challenge is the md5 of "WEBDA" + the content, so a matching one proves possession of an already stored binary, which is then attached without upload (undefined). Otherwise the upload URL is returned and nothing is attached yet: the upload stores the content, verifies it against the announced hash and attaches it then (storeBinary). A visible hash alone therefore never gives access to another object's binary.

Parameters​

object​

CoreModel

the model instance

attribute​

string

the binary attribute name

info?​

BinaryFile

optional binary file info

context?​

OperationContext<BinaryFile<{ }>>

the operation context
