Encountering an Eslint issue upon trying to implement the rule @typescript-eslint/interface-name-prefix

After implementing the rule,

"@typescript-eslint/interface-name-prefix": [ "error", { "prefixWithI": "always" }]

The system displays this error message:

Rule definition for '@typescript-eslint/interface-name-prefix' could not be located.eslint(@typescript-eslint/interface-name-prefix)

Answer №1

The guideline

@typescript-eslint/interface-name-prefix
has been eliminated as demonstrated on this page.

To achieve the same outcome of

[ "error", { "prefixWithI": "always" }]
, you can utilize the following configuration:

{
  "@typescript-eslint/naming-convention": [
    "error",
    {
      "selector": "interface",
      "format": ["PascalCase"],
      "custom": {
        "regex": "^I[A-Z]",
        "match": true
      }
    }
  ]
}

Answer №2

Looking into it further, I found another solution where you can easily define a prefix as well:

"@typescript-eslint/naming-convention": [
  "warning",
  {
    "selector": "interface",
    "format": ["PascalCase"],
    "prefix": ["I"]
  }
]
