Join HarperDB's Field CTO, Jaxon Repp, to code along and build your own web app with HarperDB's Custom Functions. Jaxon builds out an API and UI that utilizes HarperDB Custom Functions. Custom Functions are written in Node.js and the UI is in React.

Custom Functions are file-based with access to HarperDB core methods, enabling users to collapse the stack, simplify deployment, and increase performance. HarperDB Custom Functions can be configured directly through the HarperDB Studio.

To Code Along You Will Need:

• Sign up / log in to the HarperDB Studio
• ‍Have a local instance of HarperDB installed and running
• ‍Register your user-installed instance in the Studio
• ‍Custom Functions docs
• ‍GitHub Repo
• ‍Link to dataset

Note: For the purpose of this demo, Jaxon spun up two HarperDB instances, one local and one cloud. Using a local instance makes it clearer and easier to deploy static content, such as sites and web apps. We recommend using a local instance if you're following along with this demo.
