When using the default view engine ejs , Sails supports the use of partials i. Partials are basically just views that are designed to be used from within other views. They are particularly useful for reusing the same markup between different views, layouts, and even other partials.

Partials automatically inherit the view locals that are available wherever they are used.

In this article we are going to learn about EJS templating engine, it is one of the most used templating engines in the Node. In the Node. Whenever we develop full-stack web applications, there comes a need to create a web interface where users can interact with the site.

We are going to learn how to use EJS template tags and partials, create a website that reuses a footer and implements conditional statements within the EJS template. Execute the command below to initialize the package. EJS partials make it possible to create reusable views. In a real-world application, there can be over HTML files with the same footer. To reduce the development time of such a website, the partials become handy. With the partials, we can create a single footer partial file and reuse it across all the pages on the website.

Partials improve productivity because in the case of maintenance, changing the code at a single point changes all the occurrences in the pages reusing the partial.

The code snippet above loops through the posts array that will be passed from the IndexRoute file. For each post , a title, and the author name displays within the posts div.

In our case whenever you visit In the root project directory, create a file named IndexRouter. Now that you have learned how to use EJS template tags and partials, create a website that reuses a footer and implements conditional statements within the EJS template.

Are you using Vue, React, Angular, or Svelte to create web apps? I am, and if you are too, I bet it's been a while since you've written an app that renders content without these fine tools. Armed with only what comes with the browser. Years ago, this is exactly how many of us wrote web apps. While today's tools help abstract that away and add a bunch of other benefits , it is still useful to know what is happening under the covers. This experience made me realize that maybe other developers, maybe you, would appreciate a reminder of how you can render content without libraries. If anything, it's fun, educational, and might make us all respect the value of modern libraries and frameworks which handle this for us.

It uses a template and an input object to generate HTML or other text formats. Handlebars templates look like regular text with embedded Handlebars expressions. When the template is executed, these expressions are replaced with values from an input object. This method can be used for small pages and for testing. There are several other ways to use Handlebars, when you target real production systems. Some built-in helpers allow you to change the current context to a nested object. You can then access this object as if it were the root object. The built-in block-helpers each and with allow you to change the current evaluation context. The each -helper iterates an array, allowing you to access the properties of each object via simple handlebars expressions.

I would definitely advise against putting them inside partials for exactly the reason you mention. There is a high chance that one view could pull in two partials that both have references to the same js file. You've also got the performance hit of loading js before loading the rest of the html. I don't know about best practice but I choose to include any common js files inside the masterpage and then define a separate ContentPlaceHolder for some additional js files that are specific to a particular or small number of views.

Handlebars allows for template reuse through partials. Partials are normal Handlebars templates that may be called directly by other templates. This call will register the myPartial partial.

When the partial executes, it will be run under the current execution context.

In the previous article we discussed how to use partial views in ASP. Although many a times you would place a partial view on a page at development time, it is also possible to load a partial view programmatically through Ajax. To that end this article shows how that can be done. In order to load a partial view we will use jQuery Ajax. So, make sure jQuery library files are added to your wwwroot folder. Let's do the ASP.
