This file overrides your Sails app's top-level ESLint configuration, specifically for the views/ directory. It simply extends assets/.eslintrc, but omits the eol-last rule.
Certain CI environments, build systems, IDEs, and syntax-highlighting plugins for text editors run ESLint checks on inline <script> tags in HTML files to help catch common mistakes. Which is great-- except that not all of these tools are quite smart enough to understand that each <script> tag isn't a separate JavaScript file. And unfortunately, that can cause some weird issues when eol-last is enabled.
Luckily, all it takes to disable the eol-last rule for these inline <script> tags is to include this .eslintrc file in the views/ directory (which Sails does by default).
An example of this file can be found in our sample app repo, here.
