3. Express.js Lessons. Templating with EJS: Layout, Block, Partials

In real life we generally have more than one template. Moreover, if we create a website with several pages, it usually happens that a number of them are of the same design. The template systems should consider this aspect. Unfortunately, ejs doesn’t deal very well with this task. That’s why we are going to install a different templating system named ejs-locals(let us add it to app.js):

Express.js Lessons. Logger, Configuration, Templating with EJS. Part 2.

Favicon is the connect of Middleware that checks whether the url has a view of favicon.ico; if the answer is ‘yes’, it reads favicon and outputs, otherwise it transfers control further. The logger outputs a record what kind of a request we’ve received. For example, if we launch the app now, the logger will output something, when we follow:

24. Node.js Lessons.Reading Parameters From the Command Line and Environment.

Hey all! The first topic of this article is transferring of parameters and the script for Node.js. To show you the principle, we will create a file with a simple code, so add it (server.js):

23. Node.js Lessons. Domains, asynchronous try.. catch. Part 3.

How and what does app.js consist of? It is made in a way that from the very beginning we create a domain and then launch our app within this domain. Here all modules can be connected, a server gets created, etc. But why do we connect modules here? The reason is that some other modules can be added when the connection happens, and they can connect others, too.

23. Node.js Lessons. Domains, asynchronous try.. catch. Part 1.

Hey all! Our topic for today is Domains. Domains are one of the Node.js options lacking both in standard JavaScript and browser versions of JavaScript. Domains were created to catch any asynchronous errors. For instance, if we look at the server that we’ve explored in one of our previous articles (download the lesson code from here for your convenience), we will see that everything is ok when it’s working
