      "tags": ["recommended"]
    }
  }
}

Enable full set using the Deno CLI:

deno lint --rules-tags=recommended

This rule can be explictly included to or excluded from the rules present in the current tag by adding it to the include or exclude array in deno.json:

{
  "lint": {
    "rules": {
      "include": ["no-empty"],
      "exclude": ["no-empty"]
    }
  }
}

Disallows the use of empty block statements.

Empty block statements are legal but often represent that something was missed and can make code less readable. This rule ignores block statements that only contain comments. This rule also ignores empty constructors and function bodies (including arrow functions).

Invalid:

if (foo) {}

while (foo) {}

switch (foo) {}

try {
  doSomething();
} catch (e) {
} finally {
}

Valid:

if (foo) {
  // empty
}

while (foo) {
  /* empty */
}

try {
  doSomething();
} catch (e) {
  // continue regardless of error
}

try {
  doSomething();
} finally {
  /* continue regardless of error */
}
