    • OkHttp's new okhttp-brotli module implements Brotli compression. Install the interceptor to enable Brotli compression, which compresses 5-20% smaller than gzip.

      val client = OkHttpClient.Builder()
    .addInterceptor(BrotliInterceptor)
    .build()

      This artifact has a dependency on Google's Brotli decoder (95 KiB).
