@microblink/blinkid-core / loadBlinkIdCore

Function: loadBlinkIdCore()

loadBlinkIdCore(settings, progressCallback?): Promise<{ progressStatusCallback?: Promise<undefined> | Remote<ProgressStatusCallback>; createBlinkIdScanningSession: Promise<Remote<object & object & ProxyMarked>>; createProxySession: Promise<Remote<object & object & ProxyMarked>>; initBlinkId: Promise<void>; ping: Promise<number>; terminate: Promise<void>; }>

Creates and initializes a BlinkID core instance.

Parameters​

settings​

Configuration for BlinkID initialization including license key and resources location

initialMemory?​

number

The initial memory allocation for the Wasm module, in megabytes. Larger values may improve performance but increase memory usage.

licenseKey​

string

The license key required to unlock and use the BlinkID SDK. This must be a valid license key obtained from Microblink.

microblinkProxyUrl?​

string

The URL of the Microblink proxy server. This proxy handles requests to Microblink's Baltazar and Ping servers.

Requirements:

  • Must be a valid HTTPS URL
  • The proxy server must implement the expected Microblink API endpoints
  • This feature is only available if explicitly permitted by your license

Endpoints:

  • Ping: {proxyUrl}/ping
  • Baltazar: {proxyUrl}/api/v2/status/check

Example

"https://your-proxy.example.com"

resourcesLocation?​

string

The parent directory where the /resources directory is hosted. Defaults to window.location.href, at the root of the current page.

useLightweightBuild?​

boolean

Whether to use the lightweight build of the SDK. Lightweight builds have reduced size but may have limited functionality.

userId?​

string

A unique identifier for the user/session. Used for analytics and tracking purposes.

wasmVariant?​

WasmVariant

The WebAssembly module variant to use. Different variants may offer different performance/size tradeoffs.

progressCallback?​

ProgressStatusCallback

Optional callback for tracking resource download progress (WASM, data files)

Returns​

Promise<{ progressStatusCallback?: Promise<undefined> | Remote<ProgressStatusCallback>; createBlinkIdScanningSession: Promise<Remote<object & object & ProxyMarked>>; createProxySession: Promise<Remote<object & object & ProxyMarked>>; initBlinkId: Promise<void>; ping: Promise<number>; terminate: Promise<void>; }>

Promise that resolves with initialized BlinkID core instance

Throws​

Error if initialization fails
