Eslint Configuration for Multiple Files / Project

Question

How to configure eslintrc for a project like in this example?

user
└── projectA
    ├── index.html
    └── lib
        ├── .eslintrc
        ├── main.js
        └── main_lib.js

html file includes both of the js files. How .eslintrc is needed to configure to overcome function is not defined and defined but not used errors properly?

Answer 1

The rules concerned by your question are:

• for defined but not used it's the no-unused-vars rule
• for function is not defined, if you're trying to use a global method declared from an external script, then you can declare it as part of the global config in .eslintrc, like "globals": { "yourFunctionName": "readonly" }, to make eslint aware that this function was not declared by you but still it's available from somewhere.
