Of course, if you have a specific reason to need client-side JS (like certain kinds of interactivity), then it's totally valid to use it, but it shouldn't be your default - and the same applies for "SSR" tools, which are often not really designed as server-side templaters, but rather as workarounds for the deficiencies of SPAs by rendering the absolute bare minimum on the server-side so that Google doesn't complain at you anymore. However, I would generally recommend looking for something that is really only designed as a templater (even if it uses Vue/React/whatever), as opposed to something that "pre-renders the first page load" and then does the rest through client-side JS.Ĭontrary to popular belief, SPAs are actually quite slow compared to strictly server-side rendering, and so you'll generally want to default to just rendering templates and not having any client-side JS at all. initializing sessions when a request for a static file comes I have no opinion on those specific libraries, as I haven't used them. You'll usually want to put express.static at the very start of your middleware definitions, so that no time is wasted on eg. By default, Express ships with express.static, which does this for you.Īll you need to do, is to tell Express where to look for static files. You'll probably also want to serve static files on your site, whether they are CSS files, images, downloads, or anything else. This can be especially useful in combination with nested blocks, for complex cases. You can have multiple levels of inheritance - any template you are inheriting from can itself inherit from another template.This can be useful for more complex layout variations. You can nest multiple blocks with different names.You can decide to override any of them from a template, all of them, or none at all. You can have an unlimited number of blocks with different names - for example, the one in our example is called content.If you don't override a block, it will simply contain either the default content from the base template (if any is specified), or no content at all (if not). Note that you never render layout.pug directly - you still render the page layouts themselves, and they just inherit from the base template. You define a block in the base template - optionally with default content, as we've done here - and then each template that "extends" (inherits from) that base template can override such blocks. Typical examples include ES6 template strings, or this example in Pug: Hello # ) Text interpolation / String interpolation: The insertion of variable values into a string of some kind.These templaters offer a more limited feature set, but are more widely usable.

String-based templater: A template library that implements templating logic, but that has no understanding of the content it is generating - it simply concatenates together strings, potentially multiple copies of those strings with different values being used in them.

It understands document structure and thus can provide useful advanced tools like mixins, as well as more secure output escaping (since it can determine the right escaping approach from the context in which a value is used), but it also means that the templater is not useful for anything other than HTML.

HTML templater: A template library that's designed specifically for generating HTML.

a library that implements view functionality, and potentially also a custom language for specifying it (like Pug does).

View engine: Also called a "template library" or "templater", ie.

View: Also called a "template", a file that contains markup (like HTML) and optionally additional instructions on how to generate snippets of HTML, such as text interpolation, loops, conditionals, includes, and so on.
