TMDB Kotlin

TMDB Kotlin is a Kotlin Multiplatform library for fetching movies, TV shows, episodes, and all relevant information.

  • Written in Kotlin native with ktor from the ground up.
  • Support for Android, iOS, desktop, and web applications.
  • High customizable HttpClient configuration

Sample projects:

Adding to your project

The library is available on Maven Central.

Gradle

Add the Maven Central repository if it is not already there.

repositories {
    mavenCentral()
}

To use the library in a single-platform project, add a dependency.

dependencies {
    implementation("app.moviebase:tmdb-api:1.4.0")
}

In Kotlin Multiplatform projects, add the dependency to your commonMain source-set dependencies.

commonMain {
    dependencies {
        implementation("app.moviebase:tmdb-api:1.4.0")
    }
}

Usage

Most of the library follows the possibilities and naming at the official documentation. The documentation of the API endpoints is on version 3 and version 4.

Configuration

Build up your TMDB instance to access the APIs. You can configure the entire HttpClient of ktor.

val tmdb = Tmdb3 {
    tmdbApiKey = "yourApiKey"

    userAuthentication {
        authenticationToken = "auth token for version 4"
        val storage = TmdbAccountStorage() // use own class here
        loadSessionId { storage.sessionId  }
        loadGuestSessionId { storage.guestSessionId }
        loadAccessToken { storage.accessToken }
    }

    expectSuccess = false // if you want to disable exceptions
    useCache = true
    useTimeout = true
    maxRetriesOnException = 3 // retries when network calls throw an exception

    // add your own client
    httpClient(OkHttp) {
        engine {

        }
    }

    httpClient {
        // for custom HttpClient configuration
    }
}

You need to add your own TMDB API key for using the library. The instruction for the creation is in the TMDB developer guide.

Get information

For getting basic information about a movie or other media content.

val tmdb = Tmdb3("apiKey")
val movieDetail = tmdb.movies.getDetails(
    movieId = 12,
    language = "DE",
    appendResponses = listOf(AppendResponse.MOVIE_CREDITS)
)

Search

Search for TV shows by a query.

val tmdb = Tmdb3("apiKey")
val showPageResult = tmdb.search.findShows(
    query = "The Expanse",
    page = 1,
    language = "DE",
    region = "US",
    includeAdult = false
)

Discover

Discover a movie or TV show by the discover parameter class.

val discover = TmdbDiscover.Movie(
    sortBy = TmdbDiscoverMovieSortBy.POPULARITY,
    sortOrder = TmdbSortOrder.DESC,
    voteAverageGte = 5,
    voteCountGte = 200,
    releaseDate = TmdbDiscoverTimeRange.BetweenYears(from = 2020, to = 2021)
)

val discoverPageResult = tmdb.discover.discoverMovie(
    page = 1,
    region = "DE",
    language = "de",
    discover = discover
)

Alternatively, use predefined discover categories like upcoming, networks or on streaming.

val discoverCategory = DiscoverCategory.OnStreaming.Netflix(
    mediaType = TmdbMediaType.MOVIE,
    watchRegion = "DE"
)

val result = tmdb.discover.discoverByCategory(
    page = 1,
    region = "DE",
    language = "de",
    category = discoverCategory
)

Authentication

Build up your authentication URL, which you can open in the web view.

// Returns "https://www.themoviedb.org/authenticate/[request_token]?redirect_to=auth://yourApp"
val url = tmdb.authentication.requestAuthorizationUrl("auth://yourApp")

After opening the URL, TMDB version 3 returns the following URL:

yourApp://auth/login?request_token=[request_token]&approved=true

Build image URL

You can build an image URL via the poster file path and size key. More information on the TMDB images site.

val url = TmdbImageUrlBuilder.build("nBNZadXqJSdt05SHLqgT0HuC5Gm.jpg", "w154")

Or create the URL by an image class with the best matched width/height.

val url = TmdbImageUrlBuilder.build(image = movie.posterImage, width = 200, height = 300)

For creating the poster URL by the movie item.

val url = TmdbImageUrlBuilder.buildPoster(item = movie, width = 200)

Build video URL

You can build a video URL by the key value into TmdbVideo. TMDb API currently support videos from YouTube and Vimeo

val youtubeTmdbVideo = TmdbVideo(id = "123", key = "qwerasdf", site = TmdbVideoSite.YOUTUBE)
val url = TmdbImageUrlBuilder.build(youtubeTmdbVideo) // It will return `https://www.youtube.com/watch?v=qwerasdf`

val vimeoTmdbVideo = TmdbVideo(id = "123", key = "qwerasdf", site = TmdbVideoSite.VIMEO)
val url = TmdbImageUrlBuilder.build(vimeoTmdbVideo) // It will return `https://vimeo.com/qwerasdf`
