Using the Built-In API

Using HarperDB’s built-in API is as easy as making an http call to the URL and PORT of your HarperDB instance. To make it even easier, we’ve created a series of example http calls as a Postman Collection. These calls show you how to create and access sample data in HarperDB.

 

Visit The Postman Collection

 

Sample code is also available in many common languages in the sample code pane. Select the language you want from the drop down and paste the code.

Using the Built-In Studio

Once HarperDB is installed and running you can get instant gratification by using our built in administration studio.

 

  • Open a browser and navigate to: <Your-Harper-DB-IP-Address>:<Your-Harper-DB-Port>
    • For a local install, this is most often http://localhost:9925
    • For hosted instances, please use the IP address and port specified in your welcome email.
  • Login with the user name and password you created during install.
  • Add a schema, then add a table with hash attribute (akin to a primary key in a traditional RDBMS).
  • Add content to the table
    • Use the plus (+) button to add an individual record
    • Use the document icon to upload bulk data via CSV
    • Use the API via Postman or your application code to add data via the built-in API
