Handlebars features and specs

  • Simplicity
    Handlebars provides a straightforward and easy-to-learn syntax for templating, making it accessible for developers with varying levels of experience.
  • Logic-less Templates
    Encourages the separation of logic and design by only allowing minimal logic in templates. This promotes a cleaner code base and separation of concerns.
  • Extensibility
    Handlebars allows for custom helpers and partials which enable extending the templating functionality as needed.
  • Precompilation
    Templates can be precompiled, improving performance by reducing client-side parsing and rendering time.
  • Wide Adoption and Community Support
    As a popular templating engine, Handlebars has a large community of users and contributors, which provides abundant resources, plugins, and support.

Possible disadvantages of Handlebars

  • Limited Logic
    The logic-less nature of Handlebars means it supports only very basic conditionals and loops, which can be limiting for complex scenarios.
  • Verbosity
    Handlebars templates can become verbose, especially when using custom helpers or partials extensively.
  • Initial Learning Curve
    For developers coming from more logic-oriented templating engines, adjusting to Handlebars' logic-less paradigm can take some effort.
  • Dependency Management
    In larger projects, managing dependencies between templates, partials, and helpers can become complex and cumbersome.
  • Lack of Reactivity
    Handlebars does not include built-in support for data reactivity, making it less suitable for dynamic, real-time updates compared to modern frameworks like React or Vue.

Preact.js features and specs

  • Size
    Preact is very small in size (about 3KB gzipped), which makes it easy to load and faster to execute, resulting in improved performance and quicker load times.
  • Compatibility
    Preact is largely compatible with React, allowing developers to switch to Preact with minimal code changes. This makes it easier to adopt for projects already using React.
  • Performance
    Due to its small size and efficient design, Preact offers excellent performance, especially on low-powered devices and in applications with heavy user interactions.
  • Ecosystem
    Preact can work with many tools and libraries that are designed for React, giving developers access to a rich ecosystem of resources.
  • Community
    Preact has an active and growing community that provides support, plugins, and third-party tools, making it easier for developers to find solutions and share knowledge.

Possible disadvantages of Preact.js

  • Feature Set
    While Preact covers most of the core React features, it lacks some of the advanced functionality present in React, which may require additional workarounds or third-party libraries.
  • Learning Curve
    For developers coming from a non-React background, learning Preact might involve a learning curve, particularly because of its similarities and subtle differences with React.
  • Tooling Compatibility
    Although many tools designed for React can work with Preact, some might not be directly compatible, requiring additional configuration or patches.
  • Community Size
    While Preact has a supportive community, it is smaller compared to the massive React community, which can result in fewer available resources and third-party packages.
  • Maturity
    Preact, being newer and less widely adopted than React, might not have the same level of battle-tested reliability for all use cases, especially for large scale applications.

  • Chapter 7: HTML part two
    For a more robust approach, we'd probably need to install a templating language of some kind, such as Twig, EJS, Handlebars, Pug or Mustache (this is not a complete list!). Reading the documentation for posthtml-modules, you'll notice it doesn't mention package.json or any of the approaches we've used in this guide. Instead, the examples are in JavaScript and we've advised to add this to our Node application. - Source: dev.to / 2 months ago
  • How to send emails using Express and NodeJS
    As suggested by a teammate, I found out that I'll need to create the template in a different file and then replace the variables in it using some utility. So, again after searching for some packages, I figured that Handlebars would be the best solution for our problem. - Source: dev.to / 7 months ago
  • The Features of Front-end UI Components
    In dynamic web pages, especially when using template engines such as Mustache and Handlebars or libraries/frameworks such as React and Vue, the final content structure is basically generated by JS, which strengthens JS and weakens the control of HTML over the content structure. - Source: dev.to / 4 months ago
  • Make Custom Handlebar Helpers in Ghost!
    In this variable, we have the response from the Ghost instance as the full HTML of the page. Imagine that this response is the homepage of your Ghost instance. The HTML content will also include our plain text {{hello_world}}, which is displayed as plain text. If our custom helper is in this form, we can compile it using Handlebars.js (https://handlebarsjs.com/) in our middleware. Remember to install the library... - Source: dev.to / 4 months ago
  • htmx and ExpressJS
    It is a novel experience to say the least for me. I mean yes I have been using Handlebars, pug, and other templating engines but this is novel in how it changed my perspective about HTML (Just read their motivation in htmx.org). - Source: dev.to / 7 months ago
