Component: Web Apps
Web apps can be turned into plugins. This allows you to have reusable and instantiable web apps, such as custom visualizations for datasets.
To create a web app component, you need to first create a normal web app, and then use Advanced > Convert to plugin web app.
The primary files for a web app component are a webapp.json file that defines the parameters for the web app, and one or more files adapted from the normal web app that define the web app itself.
For an HTML/Javascript web app, there will be
app.js
,
body.html
and
style.css
files that define the Javascript, HTML, and CSS for the web app. Use the
dataiku.getWebAppConfig()
method to extract parameter values the user specifies on the web app Settings tab. For example, the following code snippet pulls the user-specified value of the
dataset
parameter and assigns it to a variable
dataset
.
let dataset = dataiku.getWebAppConfig()['dataset'];
For a Python Bokeh or Dash web app, there will be a
backend.py
file. Use the
get_webapp_config()
method to extract parameter values the user specifies on the web app Settings tab. For example, the following code snippet pulls the user-specified value of the
input_dataset
parameter and assigns it to a variable
input_dataset
.
input_dataset = get_webapp_config()['input_dataset']
For an R Shiny web app, there will be
server.R
and
ui.R
files. Use the
dataiku::dkuPluginConfig()
method to extract parameter values the user specifies on the web app Settings tab. For example, the following code snippet pulls the user-specified value of the
input_dataset
parameter and assigns it to a variable
input_dataset
.
input_dataset = dkuPluginConfig()['input_dataset']
