feature request: suggest naming conventions

[navh]

When I create a new project, it let me name my project with dashes. Later on, this throws an Invalid App ID, forcing me to re-name.

It would be nice if Name for your new project: a name could trigger a "some-name" is an Invalid App ID due to {reason}, are you sure? yes / Different Name loop.

Easier may just be adding a hint to the Name for your new project: -> Name (alphanum and underscores) for your new project.

Below is creating a project with a dash:

~/dev ❯ npm create ionic-svelte-app@latest                                                  
Need to install the following packages:
  create-ionic-svelte-app@0.0.29
Ok to proceed? (y) y

create-ionic-svelte-app version 0.0.29

Welcome to Ionic Svelte 

This script will install a SvelteKit project using their SvelteKit create script. 
And then adds Ionic power to it - Ionic Elements, Ionicons (optional) and CapacitorJS (optiona
l)

- Ionicons - free package of icons to use in your app
- CapacitorJs - deploy you app as Android/iOS/Electron app, and use its plugin ecosystem to bu
ild cross-platform experience, also supporting PWA!

This is BETA software; expect bugs and missing features.

Thx for the issue - a PR is definitely welcome

For this case I would opt to remove the illegal characters from the name when generating the capacitor config file, which happens in

https://github.com/Tommertom/svelte-ionic-app/blob/main/packages/create-capacitor-svelte-app/src/creator.js
from line 234 onwards (typescript and non-typescript version).

And same way in https://github.com/Tommertom/svelte-ionic-app/tree/main/packages/create-ionic-svelte-app
line 224 onwards

if (opts.types != 'typescript') out(
			'capacitor.config.json',
			`{
	"webDir":"build",
	"appId":"${opts.name}.ionic.io",
	"appName":"${opts.name}",
	"_server": {
	  "url": "http://${ip.address()}:5173/",
	  "cleartext": true
	}
}`
		);

		if (opts.types == 'typescript') out('capacitor.config.ts',
			getTSCapacitorConfig({
				appId: opts.name + '.ionic.io',
				appName: opts.name,
				ip: ip.address() // 'http://192.168.137.1'
			})
		)
	}

into (pseudo code)

const appSafeName=stripTheUglyStuff(opts.name);

if (opts.types != 'typescript') out(
			'capacitor.config.json',
			`{
	"webDir":"build",
	"appId":"${appSafeName}.ionic.io",
	"appName":"${opts.name}",
	"_server": {
	  "url": "http://${ip.address()}:5173/",
	  "cleartext": true
	}
}`
		);

		if (opts.types == 'typescript') out('capacitor.config.ts',
			getTSCapacitorConfig({
				appId: opts.name + '.ionic.io',
				appName: appSafeName,
				ip: ip.address() // 'http://192.168.137.1'
			})
		)
	}

But this is how I would solve it - happy to hear your view!
