This example features how to configure and use babel-macros
which allows you
to easily add babel plugins which export themselves as a macro without needing
to configure them.
You'll notice the configuration in .babelrc
includes the babel-macros
plugin, then we can use the preval.macro
in pages/index.js
to pre-evaluate
code at build-time. preval.macro
is effectively transforming our code, but
we didn't have to configure it to make that happen!
Specifically what we're doing is we're prevaling the username of the user who ran the build.
