Compatibility of CSS, HTML and JavaScript features

Compatibility of CSS, HTML and JavaScript features (compat-api)

compat api contains hints to check if your CSS, HTML, and JavaScript have deprecated or not broadly supported features.

Why is this important?

You need to know if all the properties that you are using in your files are compatible with the target browsers that you want to support.

Hints

How to use these hints?

To use it you will have to install it via npm:

npm install @hint/hint-compat-api

Note: You can make npm install it as a devDependency using the --save-dev parameter, or to install it globally, you can use the -g parameter. For other options see npm‘s documentation.

And then activate it via the .hintrc configuration file:

{
    "connector": {...},
    "formatters": [...],
    "hints": {
        "compat-api/css": "error",
        "compat-api/html": "error",
        ...
    },
    "parsers": [...],
    ...
}
