Express Js Static Hosting – There are some requirements that we need to access some files in the browser but if you use
As it runs on the server side, the files are not available automatically. To make this work, we need to make some code changes. So let’s do it.

This static hardcoded message is fine, but if we want to display the content of an HTML file containing CSS and Javascript files instead of text – how can we do that?

Now, if you check the application at http://localhost:5000/ , you will see that there are no errors in the console and the CSS is applied correctly and even the current date is displayed on clicking the button.
Reads the file from top to bottom and stops displaying when it finds the first matching file.
So now, when a request comes to the server for any route and the route you’re trying to access doesn’t exist on the server side, we send

You use nodemon to monitor your project’s source code and automatically restart your Node.js server when it changes.
Testing a Node.js application is beyond the scope of this tutorial. However, performing tests is important to create a robust production-ready web application.

Gitignore under the project directory to avoid making redundant or sensitive files. Fill that file with the contents of this summary or feel free to use gitignore.io to create your own custom one
The path module provides utilities for working with file and directory paths. You then use it to create cross-platform file paths to access display templates and static assets such as style sheets and images.
To see the application in action. The browser should display the string “WHATABYTE: Food For Devs” on the general page.
Modern web applications are data-driven and require views that can display data dynamically. Although you can create attractive views using static HTML templates, you can’t hydrate them with data from the server.
Just In Time Static Site Server
Instead, you use a templating engine like Pug to create dynamic views that conditionally render UI elements and that you can hydrate with values from the server. What makes Pug stand out from other offerings is its simple syntax and its support for template inheritance to easily compose pages.
To optimize page composition through templates, you use template inheritance to extend the core layout template that covers the top-level HTML structure of the page.
A variable to make the title of the page document. The value of this variable is sent from the server to the template by the route handler defined in the API, also known as
, then content can be added to that template by first expanding it and then specifying the content of the named block.

The Pug template does not use HTML tags. Instead, they use HTML element names and whitespace to define their structure. You create a parent-child relationship between elements using indentation.
, by placing the attribute key and value next to the element name and surrounding it in parentheses, resembles a function call structure:
The content of the element may precede the element name on the same line or be indented below:
To connect templates with controllers, you need to configure Express to use Pug as the display template engine.

Template, you can refresh the browser to see the changes. However, manually refreshing the browser to see updates slows down your development process. To overcome this, you use BrowserSync.
You can emulate the live refresh behavior of front-end frameworks like React and Angular in Express templates using BrowserSync. When CSS rules or function return values are changed, the browser automatically refreshes.
🛠️ Working with BrowserSync is easy. Run the following command to create a configuration file with default options:
File under your project directory, which contains a large number of default settings. You need a small subset of those options to use Browsersync to reload your web pages when you change your project’s code.

Because Browsersync only creates static servers for native HTML/JS/CSS websites. You still need to run the server
Time in milliseconds to delay refresh events after file changes to prevent Nodemon and Browsersync from overlapping, which can cause erratic behavior.
Check out the “Browser Sync Options” document for more details on all the configuration options Browsersync offers you to optimize your development workflow.
