When building a Hello World type program, I am interested in seeing the “route” working.

During early development, it is easy to just render a text.

Most tutorials use render(conn, "show.html")- which requires one to create view function, as well as show.html.eex

While this may be required later, there is an easy way

text(conn, "Hello #{user}")

I had to look for it

Sometimes json(conn, my_json) may also be useful.
