require-module-level-instantiation

Requires configured classes to be instantiated at module scope.

Rule details Problem

This rule does nothing until you configure a classes map.

Once configured, it tracks imports that match the class name and source you listed, then reports new ClassName() when it happens inside a non-top-level scope. Top-level module and global scope instantiations are allowed.

The rule handles both direct class imports and member access such as new Library.Log() when the configured class name matches the member name.

Good fit for shared services

Use this for objects that should exist once per module, such as loggers, clients, or server wrappers.

Examples

Incorrect

import Log from "@rbxts/rbxts-sleitnick-log";

function runTask() {
  const log = new Log();
  log.Info("running");
}

Correct

import Log from "@rbxts/rbxts-sleitnick-log";

const log = new Log();

function runTask() {
  log.Info("running");
}

Options

Example config:

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

export default [
  {
    plugins: {

    },
    rules: {
      "cease-nonsense/require-module-level-instantiation": [
        "error",
        {
          classes: {
            Log: "@rbxts/rbxts-sleitnick-log",
            Server: "@rbxts/net",
          },
        },
      ],
    },

];
