defineCatalogHandler

This method handles catalog requests, including search.

Arguments:

args - request object; parameters described below

Returns:

A promise that resolves to an object containing { metas: [] } with an array of Meta Preview Object

The resolving object can also include the following cache related properties:

  • { cacheMaxAge: int } (in seconds) which sets the Cache-Control header to max-age=$cacheMaxAge and overwrites the global cache time set in serveHTTP options

  • { staleRevalidate: int } (in seconds) which sets the Cache-Control header to stale-while-revalidate=$staleRevalidate

  • { staleError: int } (in seconds) which sets the Cache-Control header to stale-if-error=$staleError

Request Parameters

type - type of the catalog's content; e.g. movie, series, channel, tv (see Content Types)

id - string id of the catalog that is requested; these are set in the Manifest Object

extra - object that holds additional properties; defined below

Extra Parameters

If you wish to use these parameters, you'll need to specify them in extra for the catalog in the addon manifest

search - set in the extra object; string to search for in the catalog

genre - set in the extra object; a string to filter the feed or search results by genres

skip - set in the extra object; used for catalog pagination, refers to the number of items skipped from the beginning of the catalog; the standard page size in Stremio is 100, so the skip value will be a multiple of 100; if you return less than 100 items, Stremio will consider this to be the end of the catalog

Basic Example

builder.defineCatalogHandler(function(args) {
    if (args.type === 'movie' && args.id === 'top') {

        // we will only respond with Big Buck Bunny
        // to both feed and search requests

        const meta = {
            id: 'tt1254207',
            name: 'Big Buck Bunny',
            releaseInfo: '2008',
            poster: 'https://image.tmdb.org/t/p/w600_and_h900_bestv2/uVEFQvFMMsg4e6yb03xOfVsDz4o.jpg',
            posterShape: 'regular',
            banner: 'https://image.tmdb.org/t/p/original/aHLST0g8sOE1ixCxRDgM35SKwwp.jpg',
            type: 'movie'
        }

        if (args.extra && args.extra.search) {

            // catalog search request

            if (args.extra.search == 'big buck bunny') {
                return Promise.resolve({ metas: [meta] })
            } else {
                return Promise.resolve({ metas: [] })
            }

        } else {

            // catalog feed request

            return Promise.resolve({ metas: [meta] })

        }

    } else {
        // otherwise return empty catalog
        return Promise.resolve({ metas: [] })
    }
})
