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.
