The different pages of the app of configured in the app.py file.

Most pages are configured as files. But you can also use functions that return a Panel Viewable like the introduction function.

class LitApp(lapp.LightningFlow):
    def __init__(self):
        super().__init__()
        self.lit_intro = LitPanelPage(page=introduction, parallel=True)
        self.lit_big_data_viz = LitPanelPage(page="pages/big_data_viz.py", parallel=True)
        self.lit_crossfilter = LitPanelPage(page="pages/cross_filter.py", parallel=True)
        self.lit_streaming = LitPanelPage(page="pages/streaming.py", parallel=True)

    def run(self):
        self.lit_intro.run()
        self.lit_big_data_viz.run()
        self.lit_crossfilter.run()
        self.lit_streaming.run()

    def configure_layout(self):
        return [
            self.lit_intro.get_tab(name="Introduction"),
            self.lit_crossfilter.get_tab(name="Crossfiltering"),
            self.lit_streaming.get_tab(name="Streaming"),
            self.lit_big_data_viz.get_tab(name="Big Data Viz"),
        ]

app = lapp.LightningApp(LitApp())
