In Go, there is no one-liner to select all tuples from a Tarantool space. Yet you can use a script like this one. Call it on the instance you want to connect to.

An "HTML" file for this server, including Lua, could look like this (it would produce "1 Apple | 2 Orange | 3 Grapefruit | 4 Banana"). Create a ``templates`` directory and put this file in it:

Use the `http <https://github.com/tarantool/http/>`_ `rock` (which must first be installed) to generate HTML pages from templates. The `http <https://github.com/tarantool/http/>`_ `rock <https://rocks.tarantool.org/>`_ has a fairly simple template engine which allows execution of regular Lua code inside text blocks (like PHP). Therefore there is no need to learn new languages in order to write templates.
