enhance.dev VS awesome-tagged-templates

We are excited to present our non-trivial learning application, Enhance Movies, designed to highlight the exceptional web development experience you get from Enhance. Our movies app is built with Enhance and The Movie Database API. With a strong focus on simplicity, performance, progressive enhancement, and offline local development capabilities, this application is set to transform your understanding of what can be done by focusing on the web platform.

Those of you who’ve visited the Enhance website recently may have noticed a big change: we launched our first proper landing page! Although this project was primarily my baby over the last couple months, a lot of other folks were involved — from the stellar (and heartwarming) design & illustrations by Dani Raskovsky, to art and content direction by our very own kj, and additional ideas and feedback from the rest of the Begin team. We’re all thrilled to have this project out in the world, and we hope you’re as delighted as we are with it.

Enhance is relatively new, even compared to some of the newer tools we're talking about in this post, having been released in August 2022. It is an application framework that supports server-side rendering via Lambda functions.

Once you’re familiar with the basics (or if you are already and want to take them further), Web Components offer a standards based methodology for creating custom reusable components. As previously mentioned, Web Components require JavaScript to run in the browser by default, and their class based interface can take some getting used to. Enhance, our HTML first framework, steps around this issue by providing you with a standards compliant way to render custom elements on the server, only requiring you to interface with the Web Components JavaScript API when progressive enhancement is called for. Plus, we’ve got a really cute mascot. Give Enhance a try today!

There are so many remarkable new approaches like Astro, Qwik, 11ty and Enhance built around HTML-first promise that leverages the platform. If you decide to try out Enhance, please let us know what you think, as we’d love the feedback. Follow us on Mastodon and join our Discord.

In Part 1 of this series we covered the HTML first solution to uploading files. In this we have made some small improvements with JavaScript. The full example repository with the code in this post can be found here: https://github.com/ryanbethel/thumbnail-upload-example. Try out enhance.dev for your next project. It has pretty much everything you need to build a functional web app.

To solve the scroll jumping we can monitor the scrollTop setting for the sidebar and restore that location if we reload the page. Enhance.dev uses custom elements to build reusable components. The is one of those components. One of the benefits of custom elements is that we can easily attach JavaScript progressive enhancement behavior in a script tag defining that element.

https://enhance.dev is really powerful. Can do **way** more than a lot of the current frameworks with much less code.

The template combines HTML and JavaScript. To understand this approach, consider how PHP pages are generated. In PHP, code is embedded within the HTML. Similarly, this library leverages JavaScript template literals to achieve the same objective. From the definition: "Template literals are literals delimited with backtick (`) characters, allowing for multi-line strings, string interpolation with embedded expressions, and special constructs called tagged templates".

The numbers we are printing are monetary values so they are missing a decimal value and a currency symbol. One way we can do this is by using JavaScript template literals to append and prepend the pieces we are missing.

Tagged templates[0], the language feature that enables this, were introduced in ECMAScript 2015 apparently – arguably at least somewhat new in the lifespan of JavaScript. :)

Java is getting a similar feature with template processors[1]. It would be nice to have it in Python as well – i.e. not just f-strings, but something that (like tagged templates) allows a template function process the interpolated values to properly encode them for whatever language is appropriate (e.g. shell, SQL, HTML, etc.).

References: Template literals (Template strings)

We are using a string template literal to create the tag and the ${} syntax to provide string interpolation, that is, substituting the values of href and altText into our string.

In TypeScript, a string literal type is a type that represents a specific set of string values. For example, the type "red" | "green" | "blue" represents the set of three string values "red", "green", and "blue". Template literal types allow you to perform operations on these string literal types using the same syntax as template literal strings in JavaScript.

The example also showcases the use of inline templates, employing JavaScript Template Literals. The JSON data obtained from the GET request is accessible through the "data" variable.

These are called "tagged templates": https://developer.mozilla.org/en-US/docs/Web/JavaScript/Refe...
