Release Notes

tj/commander.js (commander)

v15.0.0

Compare Source

Commander 15 is ESM only. This is expected to be seamless for ESM consumers, but some CommonJS consumers may hit issues with tooling requiring configuration for ESM-only dependencies. See Migration Tips below.

The release of Commander 15 moves Commander 14 into maintenance. Commander 14 will get security updates for
12 months (to May 2027). For more info see Release Policy.

Added

• show excess command-arguments in error message ([#​2384])

Fixed

• Breaking: only lone --no-* option sets default option value to true, default not implicitly set when define both positive and negative option in either order ([#​2405])
• update example to use compatible character for MINGW64 ([#​2475])

Changed

• Breaking: migrated Commander implementation from CommonJS to ESM ([#​2464])
• Breaking: Commander 15 requires Node.js v22.12.0 or higher (for require(esm)).
• dev: switch tests from Jest to node:test test runner ([#​2463])

Deleted

• Breaking: removed deprecated export of commander/esm.mjs ([#​2464])

Migration Tips

Commander 15 is ESM only, but this does not mean you need to migrate to ESM to use it. Importing ESM from CommonJS is
supported by Node.js, and Bun, and Deno. Hopefully it Just Works for you! However, you may be using a different runtime or
some other part of your setup that may not yet natively support importing ESM from CommonJS, such as your testing framework
or bundler.

If you have problems using Commander 15 in your environment, one option is stay on Commander 14 for now. Commander 14 will
get security updates until May 2027 and things will hopefully improve for your setup in the meantime.

• internal refactor of Help class adding .formatItemList() and .groupItems() methods ([#​2328])

  • note: support for dual long option flags added in Commander 13.1
• Breaking: throw on multiple calls to .parse() if storeOptionsAsProperties: true ([#​2299])
• TypeScript: include implicit this in parameters for action handler callback ([#​2197])

Deleted

• Breaking: Help.wrap() refactored into formatItem() and boxWrap() ([#​2251])

Migration Tips

Excess command-arguments

It is now an error for the user to specify more command-arguments than are expected. (allowExcessArguments is now false by default.)

Old code:

program.option('-p, --port <number>', 'port number');
program.action((options) => {
  console.log(program.args);
});

Now shows an error:

$ node example.js a b c
error: too many arguments. Expected 0 arguments but got 3.

You can declare the expected arguments. The help will then be more accurate too. Note that declaring
new arguments will change what is passed to the action handler.

program.option('-p, --port <number>', 'port number');
program.argument('[args...]', 'remote command and arguments'); // expecting zero or more arguments
program.action((args, options) => {
  console.log(args);
});

Or you could suppress the error, useful for minimising changes in legacy code.

program.option('-p, --port', 'port number');
program.allowExcessArguments();
program.action((options) => {
  console.log(program.args);
});

Stricter option flag parsing

Commander now throws an error for option flag combinations that are not supported.
In particular, a short flag with multiple characters is now an error.

program.option('-ws, --workspace'); // throws error

A short option has a single character:

program.option('-w, --workspace');

Or from Commander 13.1 you can have an extra long flag instead of a short flag to allow a more memorable shortcut for the full name:

program.option('--ws, --workspace');
