#angular

How to use ng new

Example of usage :

ng new my-app --routing --style=scss --skip-tests --strict

Option	What it does
`--routing`	Adds Angular routing (creates `app-routing.module.ts`)
`--prefix=custom`	Sets a custom prefix for components (e.g., `<custom-header>` instead of `<app-header>`)
`--strict`	Enables strict TypeScript settings (recommended for large/serious apps)
`--skip-install`	Skips running `npm install` after creating the project
`--skip-tests`	Omits test files from generated components
`--inline-style`	Puts styles directly in the component file (not in a separate `.scss` or `.css`)
`--inline-template`	Puts HTML templates inline instead of in a separate file
`--standalone`	Creates a project using standalone components (experimental, advanced)
`--minimal`	Creates the smallest possible setup (no testing, no routing, minimal config)
`--directory=your-folder`	Specifies a folder to create the project in
`--legacy-peer-deps`	Useful when npm dependencies break (works like `npm install --legacy-peer-deps`)
