Quickstart

If you haven’t already, install Blu.

Next, create a directory called app. Inside this directory, create a file called __index__.py with the following content:

app/__index__.py

from blu.html import body, head, html

def __page__():
    return html[
        head,
        body['Hello World!'],
    ]

Your project should look like this:

app/
  __index__.py

To start up a development instance of your app, enter the following in a terminal (make sure you are in the parent directory of app/, not in the app/ directory itself):

$ blu

This will start up the app and output a url where you can access it (http://127.0.0.1:{some port}). Visit this url in a web browser, and you should see the following:

Hello World!

If it works, you’ve created a simple web app using Blu.
