Getting Started with H2O Wave

This project was bootstrapped with wave init command.

Running the app

Make sure you have activated a Python virtual environment with h2o-wave installed.

If you haven't created a python env yet, simply run the following command (assuming Python 3.7 is installed properly).

For MacOS / Linux:

python3 -m venv venv
source venv/bin/activate
pip install h2o-wave

For Windows:

python3 -m venv venv
venv\Scripts\activate.bat
pip install h2o-wave

Once the virtual environment is setup and active, run:

# To run first example
wave run app1.py

# To run thelast example App
wave run app13.py

Which will start a Wave app at http://localhost:10101.

Application topics

This is is the set of applications (from app1 to app13) which demonstrate how to develop Wave application step by step. Each step adds additional functionality.

List of training Apps:

• app1 through app8 - step by step development of Employee Churn dashboard
• app9 - adding debugging and logging
• app10 - refactoring app9 to refresh content only when there is a change due to user interaction. In the previous steps we have re-drawn cards every time there was a change
• app11 - This app is the same as app10, but it pulls data from Delta Lake storage.
• app12 - This app adds pagination logic to app10.
• app13 - This app adds tabs and tab switching to app12. Cards are recreated only when tab switching is detected.

Interactive Wave University examples

If you don't feel like going through the docs because you are more of a hands-on person, you can try our Wave University app.

Within your activated virtual environment, run:

wave learn

The command requires h2o_wave_university to be installed. To do that, run:

pip install h2o_wave_university
