I have created a CLI with yargs. It has a series of nested commands. All the commands work nicely, but I also want to have a welcome/info message when no command is given or if a command that does not exist is supplied.
I have been unable to get this to work, what efforts I have used either display a message all the time or not at all. Any suggestions would be welcome
Took quite a lot of docs reading but got there in the end, the $0 is used as a catch all command and can be added to the builder.
yargs(hideBin(process.argv))
.version(require('../package.json').version)
.alias('h', 'help')
.help()
.command('stuff', 'makes stuff happen', () => {}, (_) => {
...
})
.command('$0', 'the default command', () => {}, (_) => {
console.log(defaultMessage)
})
.parse();
