Add a partials subfolder in the views folder to hold the partials. In the folder, create a file named app.js and a folder named views to hold the views we’ll render through Express. This is where we’ll write all our code for this project. Set up a new npm project and install Express by typing the following commands in your terminal: npm initĬreate a src folder. This post will discuss the following template engines for Express: There are a number of template engines available today, and the more popular ones include Pug (fka Jade), Handlebars, EJS, Mustache, Swig, and others.

This helps prevent code duplication and make changes easier to implement. One essential feature of template engines is that they allow us to create reusable components called partials, which can be reused in other files. These are compiled in real time as the template gets rendered. Then, at the appropriate route to render the template, you assign values to the variables declared in your template file. Luckily, Express.js provides us a way to create dynamic HTML pages from our server-side applications through a template engine.Ī template engine works in a rather simple manner: you create a template and, with the appropriate syntax, pass variables into it. While it’s possible to render static websites from a server, there are a lot of limitations with this approach, including code duplication and a lack of flexibility - especially when it comes to reading data from a database.
