Migration Tips

If you have a simple program without an action handler, you will now get an error if there are missing command-arguments.

program
  .option('-d, --debug')
  .arguments('<file>');
program.parse();
$ node trivial.js 
error: missing required argument 'file'

If you want to show the help in this situation, you could check the arguments before parsing:

if (process.argv.length === 2)
  program.help();
program.parse();

Or, you might choose to show the help after any user error:

program.showHelpAfterError();

Migration Tips

The biggest change is the parsed option values. Previously the options were stored by default as properties on the command object, and now the options are stored separately.

If you wish to restore the old behaviour and get running quickly you can call .storeOptionsAsProperties(). To allow you to move to the new code patterns incrementally, the action handler will be passed the command twice, to match the new "options" and "command" parameters (see below).

program options

Use the .opts() method to access the options. This is available on any command but is used most with the program.

program.option('-d, --debug');
program.parse();
// Old code before Commander 7
if (program.debug) console.log(`Program name is ${program.name()}`);
// New code
const options = program.opts();
if (options.debug) console.log(`Program name is ${program.name()}`);

action handler

The action handler gets passed a parameter for each command-argument you declared. Previously by default the next parameter was the command object with the options as properties. Now the next two parameters are instead the options and the command. If you only accessed the options there may be no code changes required.

program
  .command('compress <filename>')
  .option('-t, --trace')
  // Old code before Commander 7
  .action((filename, cmd) => {
    if (cmd.trace) console.log(`Command name is ${cmd.name()}`);
  });
  // New code
  .action((filename, options, command) => {
    if (options.trace) console.log(`Command name is ${command.name()}`);
  });

If you already set .storeOptionsAsProperties(false) you may still need to adjust your code.

program
  .command('compress <filename>')
  .storeOptionsAsProperties(false)
  .option('-t, --trace')
  // Old code before Commander 7
  .action((filename, command) => {
    if (command.opts().trace) console.log(`Command name is ${command.name()}`);
  });
   // New code
   .action((filename, options, command) => {
      if (command.opts().trace) console.log(`Command name is ${command.name()}`);
   });

Migration Tips

If you use .on('command:*') or more complicated tests to detect an unrecognised subcommand, you may be able to delete the code and rely on the default behaviour.

If you use program.args or more complicated tests to detect a missing subcommand, you may be able to delete the code and rely on the default behaviour.

If you use .command('*') to add a default command, you may be be able to switch to isDefault:true with a named command.

If you want to continue combining short options with optional values as though they were boolean flags, set combineFlagAndOptionalValue(false) to expand -fb to -f -b rather than -f b.

  • Fix behavior of --no-* options ([#​795])
    • can now define both --foo and --no-foo

    • allow boolean default value, such as from environment ([#​987])
  • Increment inspector port for spawned subcommands ([#​991])
    • e.g. node --inspect myCommand.js clone
Migration Tips

The custom event for a negated option like --no-foo is option:no-foo (previously option:foo).

program
  .option('--no-foo')
  .on('option:no-foo', () => {
    console.log('removing foo');
  });

When using TypeScript, adding a command does not allow an explicit undefined for an unwanted executable description (e.g for a command with an action handler).

program
  .command('action1', undefined, { noHelp: true }) // No longer valid
  .command('action2', { noHelp: true }) // Correct
