getSignedTransformUrl

function getSignedTransformUrl(
   asset,
   opts,
   signingKey): Promise<string> | null;

Defined in: packages/asset-client/src/transform.ts:327

Build AND sign a transform URL, allowing an off-ladder custom width.

This is the escape hatch for SignedTransformOptions: off-ladder widths only pass the edge whitelist when the URL is signed, so building one and signing it must happen together. For on-ladder widths prefer the plain getTransformUrl (+ signTransformUrl if you need a signature).

Returns null only when opts serialize to an empty DSL (no transform requested) — same contract as getTransformUrl.

Parameters

Parameter	Type
asset	Pick<AssetDTO, "sha">
opts	SignedTransformOptions
signingKey	string

Returns

Promise<string> | null
