What is point-of-view?

@fastify/view is a plugin for Fastify, a fast web framework for Node.js. It lets your server send back web pages that are built from reusable HTML templates rather than static files. Instead of writing raw HTML for every single page, you create a template once, fill in the blanks with data from your server, and send the finished page to the user's browser. This approach saves time and keeps your code organized. At a high level, the plugin works by adding a view method to your server's reply object. When a user visits a route, your server takes a template file, injects the relevant data into it, and returns the resulting HTML. It supports eleven different templating engines out of the box, including popular ones like EJS, Handlebars, and Pug. You simply pick the engine you prefer, register the plugin, and call the view method whenever you need to render a page. This project is ideal for developers building web applications or websites with Fastify who need to generate dynamic HTML on the server side. For example, if you are building an e-commerce site, you can use one template for a product page and dynamically insert the product name, price, and image based on the URL the user visits. It also supports layouts, which let you wrap your page content in a shared header and footer, so you do not have to repeat that boilerplate code across every page. A notable feature is its built-in performance optimization. In production mode, the plugin heavily caches templates to keep response times fast, but in development mode, it reloads them every time so you can see your changes instantly. It also allows you to register multiple engines at once if you need to serve different layouts for different parts of your application, like rendering separate templates for mobile and desktop versions of your site.
