Environment variables

All the environment variables defined at runtime that have the "RAZZLE_" prefix, are available in the browser under window.env

ex: If we start the application with an env variable

RAZZLE_MY_VARIABLE=some_value build/server.js

In the frontend we can access this variable with:

window.env.RAZZLE_MY_VARIABLE

VOLTO_ROBOTSTXT

You can override the robots.txt file with an environment variable called VOLTO_ROBOTSTXT. This is useful when using the same build on multiple websites (for example a test website) to forbid robots from crawling it.

$ VOLTO_ROBOTSTXT="User-agent: *
Disallow: /" yarn start
