About this widget

The reverseSnippet function returns any attribute from a hit into its snippeted form, when relevant.

This function leverages the snippeting feature of Algolia and is designed to work with the hits or infiniteHits widget. This helper is available in both forms: as a string and as a function.

The attribute must be set in attributesToSnippet, either inside the Algolia dashboard or at runtime:

reverseSnippet({
  // ...
  attribute: 'description.full',
});
hit
type: object
Required

Original hit object provided to the function. Note that the value is already bound to the function inside a string template, so you don’t have to provide it. For this to work, the provided object must have a _snippetResult[attribute].value property.
