require-serialized-numeric-data-type

Requires DataType.* instead of raw number in serialization type positions.

Rule details Problem

In the default type-arguments mode, the rule only checks type arguments passed to selected functions. By default, that means registerComponent<...>().

It reports raw number and nested uses of number, including unions, intersections, arrays, tuples, type literals, indexed access types, and generic type arguments. DataType.u8, DataType.i16, DataType.f32, and the other supported DataType.* variants are allowed.

In all mode, the rule also checks function parameters, return types, properties, type aliases, and variable type annotations across the file. When strict: true, it uses the TypeScript type checker so aliased number types can be reported too.

Supported DataType members

The rule recognizes u8, u16, u32, i8, i16, i32, f32, and f64.

Examples

Incorrect

const Health = registerComponent<number>({ replicated: true });

type Payload = { value: number };

Correct

const Health = registerComponent<DataType.u16>({ replicated: true });

type Payload = { value: DataType.u16 };

Options

Option	Type	Default
functionNames	string[]	["registerComponent"]
mode	"type-arguments" | "all"	"type-arguments"
strict	boolean	false

Example config:

import ceaseNonsense from "eslint-plugin-cease-nonsense";

export default [
  {
    plugins: {
      "cease-nonsense": ceaseNonsense,
    },
    rules: {
      "cease-nonsense/require-serialized-numeric-data-type": [
        "error",
        {
          mode: "type-arguments",
          functionNames: ["registerComponent", "createEvent"],
        },
      ],
    },
  },
];
