* نکته: پروژه انگیولار متریال ۲ در زمان نوشتن این مقاله به تازگی نسخه بتا ۵ را ارائه داده و همچنان در حال توسعه است. این بدان معنی است که ممکن است همه چیز به سرعت تغییر یابد. 

مقدمه

انگیولار متریال ۲ همانند انگیولار متریال یک، تمامی المانهای مورد نیاز برای طراحی یک برنامه تک صفحه‌ای را به راحتی فراهم می‌کند (هرچند تمامی المانهای آن در نسخه بتا پیاده سازی نشده‌اند). خبر خوب اینکه، اکثر کامپوننتهای ارائه شده در انگیولار متریال ۲ از قالب راست به چپ پشتیبانی می‌کنند و اعمال این قالب به سادگی اضافه کردن خصوصیت dir یک المان به rtl است.

در صفحه گیت‌هاب انگیولار متریال ۲ آمده‌است که انگیولار متریال ۲، واسط‌های کاربری با کیفیت بالا را ارائه می‌دهد و در ادامه منظورش را از «کیفیت بالا»، اینگونه بیان می‌کند:

1. بین‌المللی و قابل دسترس برای همه به نحوی که تمامی کاربران می‌توانند از آنها استفاده کنند (عدم مشکل در چند زبانه بودن و پشتیبانی از قالب راست به چپ و چپ به راست) .
   
2. دارای APIهای ساده برای توسعه دهندگان. 
   
3. رفتار مورد انتظار و بدون خطا در تمامی موردهای کاری

4. تست تمامی رفتارها توسط تست یکپارچگی (unit test ) و تست واحد ( integration test ) 
   

5. قابلیت سفارشی سازی در چارچوب طراحی متریال 
   

6. بهره‌وری بالا 
   

7. کد تمیز و مستندات خوب 
   

شروع کار با انگیولار متریال ۲ 

قدم اول: نصب angular-material و hammerjs

برای شروع بایستی Angular Material و angular animations و hammer.js را توسط npm به صورت زیر نصب کنید.

npm install --save @angular/material @angular/animations

npm install --save hammerjs

angular/material@: بسته مربوط به انگیولار متریال دو را نصب خواهد کرد.

angular/animations@: این بسته امکاناتی جهت ساخت افکت‌های ویژه هنگام تغییر صفحات، یا بارگذاری المنت‌ها را از طریق کدهای css نوشته شده، به راحتی امکان‌پذیر می‌کند.

Hammerjs: برخی از کامپوننتهای موجود در انگیولار متریال ۲ وابسته به کتابخانه Hammerjs هستند. (از جمله md-slide-toggle و md-slider, mdTooltip)
