Why terminal does not show other yargs command?

Question

When i run command node app.js --help , terminal shows only add command meanwhile i have defined three commands and all of them works. And when i use parse() method instead of argv why i get 'Removing a note' printed 2 times ?

const yargs = require('yargs');


yargs.command({
    command:'add',
    describe:'Adds new note',
    handler:function(){
    console.log('Adding a note')
    }
}).argv;

yargs.command({
    command:'remove',
    describe:'Removes a note',
    handler:function(){
    console.log('Removing a note')
    }
 }).argv;

yargs.command({
    command:'list',
    describe:'Fetches a list of notes',
    handler:function(){
    console.log('Fetching a list')
    }
 }).argv;

Commands:
  app.js add  Adds new note

Options:
  --help     Show help                                                 [boolean]
  --version  Show version number                                       [boolean]

You are calling .argv which is stopping the process before the others can be defined before help is invoked.

Remove .argv from all but the last command definition you create is the simplest fix for this.

const yargs = require('yargs');


yargs.command({
    command:'add',
    describe:'Adds new note',
    handler:function(){
    console.log('Adding a note')
    }
});

yargs.command({
    command:'remove',
    describe:'Removes a note',
    handler:function(){
    console.log('Removing a note')
    }
 });

yargs.command({
    command:'list',
    describe:'Fetches a list of notes',
    handler:function(){
    console.log('Fetching a list')
    }
 }).argv;
