Problem

We have been slowly moving towards removing the default export of global Command instance. Already removed from the README, removed from the TypeScript, and omitted from the esm interface.

Recently observed some problems due to the legacy export: #2013 #2014

Deprecation:

## Default import of global Command object
The default import was a global Command object.
```js
const program = require('commander');
```
The global Command object is exported as `program` from Commander v5, or import the Command object.
```js
const { program } = require('commander');
// or
const { Command } = require('commander');
const program = new Command()
```
- Removed from README in Commander v5.
- Deprecated from Commander v7.
- Removed from TypeScript declarations in Commander v8.

Issue: #2016

Solution

Remove from the CommonJS exports too!

ChangeLog

  • Removed: breaking: removed default export of a global Command instance from CommonJS (use the named program export instead)

### Release Notes

<details>
<summary>tj/commander.js (commander)</summary>

### [`v12.0.0`](https://github.com/tj/commander.js/blob/HEAD/CHANGELOG.md#1200-2024-02-03)

[Compare Source](tj/commander.js@v11.1.0...v12.0.0)

##### Added

-   `.addHelpOption()` as another way of configuring built-in help option (\[[#&#8203;2006](tj/commander.js#2006)])
-   `.helpCommand()` for configuring built-in help command (\[[#&#8203;2087](tj/commander.js#2087)])

##### Fixed

-   *Breaking:* use non-zero exit code when spawned executable subcommand terminates due to a signal (\[[#&#8203;2023](tj/commander.js#2023)])
-   *Breaking:* check `passThroughOptions` constraints when using `.addCommand` and throw if parent command does not have `.enablePositionalOptions()` enabled (\[[#&#8203;1937](tj/commander.js#1937)])

##### Changed

-   *Breaking:* Commander 12 requires Node.js v18 or higher (\[[#&#8203;2027](tj/commander.js#2027)])
-   *Breaking:* throw an error if add an option with a flag which is already in use (\[[#&#8203;2055](tj/commander.js#2055)])
-   *Breaking:* throw an error if add a command with name or alias which is already in use (\[[#&#8203;2059](tj/commander.js#2059)])
-   *Breaking:* throw error when calling `.storeOptionsAsProperties()` after setting an option value (\[[#&#8203;1928](tj/commander.js#1928)])
-   replace non-standard JSDoc of `@api private` with documented `@private` (\[[#&#8203;1949](tj/commander.js#1949)])
-   `.addHelpCommand()` now takes a Command (passing string or boolean still works as before but deprecated) (\[[#&#8203;2087](tj/commander.js#2087)])
-   refactor internal implementation of built-in help option (\[[#&#8203;2006](tj/commander.js#2006)])
-   refactor internal implementation of built-in help command (\[[#&#8203;2087](tj/commander.js#2087)])

##### Deprecated

-   `.addHelpCommand()` passing string or boolean (use `.helpCommand()` or pass a Command) (\[[#&#8203;2087](tj/commander.js#2087)])

##### Removed

-   *Breaking:* removed default export of a global Command instance from CommonJS (use the named `program` export instead) (\[[#&#8203;2017](tj/commander.js#2017)])

##### Migration Tips

**global program**

If you are using the [deprecated](./docs/deprecated.md#default-import-of-global-command-object) default import of the global Command object, you need to switch to using a named import (or create a new `Command`).

```js
// const program = require('commander');
const { program } = require('commander');
```

**option and command clashes**

A couple of configuration problems now throw an error, which will pick up issues in existing programs:

-   adding an option which uses the same flag as a previous option
-   adding a command which uses the same name or alias as a previous command
