Setting up Eslint for Various Files / Project Configuration

What is the process for setting up eslintrc in a project similar to the one shown below?

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

The html file includes both of the js files. How should the .eslintrc be configured to address issues like function is not defined and defined but not used errors effectively?

Answer №1

The guidelines related to your query include:

  • When a variable is defined but not used, the rule is no-unused-vars
  • If you encounter an error stating function is not defined, and you are attempting to utilize a global method from an external script, consider declaring it within the global configuration in your .eslintrc file. For example:
    "globals": { "yourFunctionName": "readonly" }
    . This informs eslint that the function was not created by you, but it is accessible from elsewhere.
