Access Rails settings (development.yml , test.yml etc.) #1895

How to access rails settings variable (from development.yml etc.) inside JavaScript?

jakeNiemiec · 2019-01-17T17:24:03Z

You can put something like this (and more) in your <head>. (or anywhere, it just needs to be before any javascript_pack_tags)

<script>
  window.mySettingsVariable = <%== @my_settings_variable.to_json %>;
</script>

A more complecated, but just as valid way of doing this would be to use the DefinePlugin in your config/environment.js. Here is one example I found: #1304 (comment)

Note: Anyone who visits your site can access variables set on the window object. Be careful not to set any sensitive info.

Ya thats right. I'm afraid binding to a window object might have security consequences.

JavaScript is completely client-side, anything you expose to is will be available to your users (even if not assigned to window). JS should never come into contact with data that has security consequences.
