Catch that Millionth Download with Bintray’s New Statistics API

Want to know exactly how many times your packages have been downloaded? Bintray has always given you download statistics through its UI, but now you can also get them for professional repositories via REST API. Detailed statistics on downloads per version over any time frame give you deep insights into how your software releases are consumed.
If you have never used statistics in Bintray, go ahead and check it out in the user guide.

Let’s see an example
Say I want to get the daily number of downloads of ‘myCoolPackage’ from October 1st to October 8th, 2015. This is what the stats look like in the Bintray UI:

myCoolPackage Downloads UI Stats Per Week

According to the chart, ‘myCoolPackage’ was downloaded a total of 147,752 times in that period. We can clearly see that there were downloads every day; there were dips on October 4th (Sunday) and October 8th (the chart was generated on October 8th around midday), and the most popular versions were 1.1.0 and 1.2.0.

Now you can get all this information programmatically using the new REST API. Here’s the “daily downloads” API as it is described in the REST API documentation:

GET /packages/:subject/:repo/:package/stats/time_range_downloads

To get the statistics displayed in the chart above, I would use the following command:

curl -X GET "https://api.bintray.com/packages/tamarUser/Maven/myCoolPackage/stats/time_range_downloads" -u tamarUser:***my-top-secret-api-key*** -H "content-type:application/json" -d “{\"from\":\"2015-10-01T12:08:56.235z\",\"to\":\"2015-10-08T12:08:56.235z\"}"

I get the following response in JSON format:

{
  "from":"2015-10-01T00:00:00.000Z",
  "to":"2015-10-08T23:59:59.999Z",
  "records":[
      {"date":"2015-10-01","downloads":
        [{"version":"1.0.5","count":1939},
         {"version":"1.1.0","count":6950},
         {"version":"1.1.3","count":293},
         {"version":"1.1.7","count":116},
         {"version":"1.2.0","count":10111},
         {"version":"1.2.1","count":1329},
         {"version":"1.2.2","count":1706}]},
      {"date":"2015-10-02","downloads":
        [{"version":"1.0.5","count":315},
         {"version":"1.1.0","count":6975},
         {"version":"1.1.3","count":198},
         {"version":"1.1.7","count":121},
         {"version":"1.2.0","count":9967},
         {"version":"1.2.1","count":1290},
         {"version":"1.2.2","count":1759}]},
      {"date":"2015-10-03","downloads":
      ...]
}

The response provides all of the same data that Bintray uses to create the chart in the UI. For each day within the requested date range in which downloads occurred, it lists the number of downloads per version. As simple JSON output, you can easily parse the response and use it any way that helps you analyze your package downloads quickly and effectively. You are now able to identify trends in downloads, your popular versions and more.

Other statistics REST APIs include: total downloads and downloads by country. Keep an eye on this blog to hear about new APIs when we add them.

Good luck!

Increase your Maven Package’s Exposure by Adding it to JCenter

If you already distribute your Maven packages via Bintray, your packages can gain further exposure by including them in Bintray’s JCenter! (if you are not very familiar with Bintray’s support for Maven, please refer to the user guide and to my previous post).

JCenter is the repository with the biggest collection of Maven artifacts in the world. And it’s on the best software distribution platform around – Bintray. This is where you want your Maven packages to be! CDN speed, user exposure, and live statistics to monitor the use of your artifacts are some of the benefits you get from JCenter. And if you really want to, you can also have your project synced with the older Maven Central repository.

Submit an Inclusion Request to JCenter

To promote sharing of packages within the developer community, once you have uploaded a package to one of your repositories, you can submit a request to the owner of any other repository to have your package included in theirs. If your request is granted, your package can be found just like any other package in that repository. You still maintain full control over the package in your own repository, and any changes you make to it, such as delivering new versions, or even removing it, are automatically synced to the other repository in which it’s included. So to maximize exposure of your Maven package in Bintray, all you need to do is request to have it added to JCenter.
In order to submit a request, just click on the ‘Add to JCenter’ button:

Add Package To JCenter
Once a Bintray moderator approves your request, your package will be available on JCenter, and you will receive a message into your Bintray mailbox. You will also see that your package is now linked to JCenter:
Maven Projects Linked To JCenter

Sync with Maven Central

At this point you can also have JCenter sync your package to Maven Central if you need to serve frameworks still using this repository. All you need to do is click on the ‘Maven Central’ link as shown above. Remember that you need to provide your Sonatype user name to Bintray before the syncing, but don’t worry, Bintray will remind you to do so if you haven’t already added it to your profile under Accounts:
Accounts Sonatype
Bintray takes care of the rest. Please also refer to the step by step instructions for how to sync your artifacts with Maven Central.

Good luck, and keep your package front and JCenter!
