Rules configuration

Rules are made up by a name and a configuration array. The configuration array contains:

• Level [0..2]: 0 disables the rule. For 1 it will be considered a warning for 2 an error.
• Applicable always|never: never inverts the rule.
• Value: value to use for this rule.

Rule configurations are either of type array residing on a key with the rule's name as key on the rules object or of type function returning type array or Promise<array>. This means all of the following notations are supported.

Plain array

:::code-group

export default {
  // ...
  rules: {
    "header-max-length": [0, "always", 72], // [!code focus]
  },
  // ...
};

:::

Function returning array

:::code-group

export default {
  // ...
  rules: {
    "header-max-length": () => [0, "always", 72], // [!code focus]
  },
  // ...
};

:::

Async function returning array

:::code-group

export default {
  // ...
  rules: {
    "header-max-length": async () => [0, "always", 72], // [!code focus]
  },
  // ...
};
