Build a Lightning component (intermediate)
##########################################
**Audience:** Users who want to connect a UI to a Lightning component.
----
*****************************
Add a web user interface (UI)
*****************************
Every lightning component can have its own user interface (UI). Lightning components support any kind
of UI interface such as react.js, vue.js, streamlit, gradio, dash, web urls, etc...(`full list here <../add_web_ui/index.html>`_).
Let's say that we have a user interface defined in html:
.. code:: html
<!--index.html-->
<html>
<head>
</head>
<body>
<h1>Hello World<h1>
</body>
</html>
To *connect* this user interface to the component, define the configure_layout method:
.. code:: python
:emphasize-lines: 5, 6
import lightning_app as la
from lightning_app.frontend.web import StaticWebFrontend
class LitHTMLComponent(lapp.LightningFlow):
def configure_layout(self):
return StaticWebFrontend(serve_dir="path/to/folder/with/index.html/inside")
Finally, route the component's UI through the root component's **configure_layout** method:
.. code:: python
:emphasize-lines: 14
# app.py
import lightning_app as la
class LitHTMLComponent(lapp.LightningFlow):
def configure_layout(self):
return lapp.frontend.web.StaticWebFrontend(serve_dir="path/to/folder/with/index.html/inside")
class LitApp(lapp.LightningFlow):
def __init__(self):
super().__init__()
self.lit_html_component = LitHTMLComponent()
def configure_layout(self):
tab1 = {"name": "home", "content": self.lit_html_component}
return tab1
app = lapp.LightningApp(LitApp())
Run your app and you'll see the UI on the Lightning App view:
.. code:: bash
lightning run app app.py
