isSupportedFile

isSupportedFile(file: FileTypeQuery): boolean

Defined in: src/lib/processors/preprocessor.ts:69 

Test whether the SDK can extract text from the given file.

Use this for upload-time validation in drag-drop handlers, file-picker onChange, or paste handlers — block at the boundary with a clear message instead of silently accepting a file the model will never see.

Note: this covers files handled by the SDK’s text extractors (PDF, Word, Excel, Zip, plain text/markdown/JSON, etc.). Image files (image/*) are sent directly as image_url content parts and are NOT handled by processors — combine with an image check in your validation:

const ok = file.type.startsWith("image/") || isSupportedFile(file);

Parameters

Returns

boolean
