Installation

npm install --save-dev eslint-plugin-no-deprecated-variable

Usage

Prevent usage of specific deprecated variable.

For example, we want to prevent usage of DEPRECATED_COLORS variable and prefer usage of COLORS with a matching object of preferences.

We could setup our rule like that:

    "no-deprecated-variable": [
      2,
      {
        "properties": [{
          "deprecate": "DEPRECATED_COLORS",
          "matchingVariable": "COLORS",
          "matchObject": {
            "white": "light[900]",
            "secondary": "warning[500]",
          }
        }]
      }
    ],

With those options, the rule will trigger an error when we use DEPRECATED_COLORS and suggest to fix the error by replacing DEPRECATED_COLORS.white by COLORS.light[900].
