9/17/2023 0 Comments Hybridsjs unpkg![]() – Composition over inheritance - easy re-use, merge or split property definitions – No global lifecycle - independent properties with own simplified lifecycle methods – The simplest definition - just plain objects and pure functions – no class and this syntax I really appreciate it when a tool’s documentation has a bullet point list of all its features. So if you are into functional programming, Hybrids may be the Web Component library for you. The first line on their site explains this: “Hybrids is a UI library for creating web components with strong declarative and functional approach based on plain objects and pure functions.” hybridsĪt first glance at the code for the counter component, you may notice the lack of a Class. Here are a few of the many options available. If this seems to be too much boilerplate and/or you want to create a lot of components with more functionality, a tool may be right for you. This way you don’t have to worry about “library lock-in”. If the components you build are not much more complex than this example, the Vanilla JavaScript option may be for you. You can find more information on lifecycle callbacks on the MDN web docs.įinally, the new Class is attached to the custom element name using fine. This is really important, especially when doing things like timers, to prevent memory leaks. Here we are adding and removing event listeners from the buttons. These are called when the component is appended or removed from the page. Then we have the component’s connectedCallback() and disconnectedCallback() lifecycle methods. Otherwise, the counter value would never change. Notice how whenever inc() and dec() are called, update() is also activated. Next, we define the functions of the component inc(), dec(), and update(). Once rendered, we can get references to the different parts and band the actions of the component. The template and styling are then attached to the Shadow DOM of that we can see it on the page. The component’s template is then set as html and it’s styling as style. Now let’s get to comparing! Vanilla JavaScriptĪs a baseline, let’s see what it takes to create the Counter component with Vanilla JavaScript.įirst, we are extending the HTMLElement base class as a starting point for our Web Component. In contrast, compilers have a build step when creating a component that will generate the code necessary to work without needing the tool later. For libraries, the component relies on the tool used to handle rendering and updating. The difference lies in when the Web Component gets used. ![]() When starting to build on v or in your research, you will see the terms “library” or “compiler” when describing a tool. The site offers a wide variety of tools to use. The sites list all of its many capabilities, but the one we will be utilizing is creating the same starter Web Component, a counter, with a single click. – Backing: Who’s maintaining the tool? Who’s using it?ĭoing research, I came across a website that is a playground for developers building Web Components. ![]() ![]() – Support: Forums, Discord, Slack, Community, Blogs/articles, YouTube, GitHub – Ease of set up: Are there a lot of steps to get a web component started? – Documentation: Examples? Clear instructions? Starter projects? – Features: What do we get out of the box? In addition to the code, other criteria we will be comparing are: The same component will be built so that the differences in code can be highlighted. In this post, we will go through a few of these tools and compare them. Again, as with development, there are many tools to choose from, all based on different opinions on the best way to create Web Components. They can help abstract some of that boilerplate into cleaner code and provide a more efficient workflow. Web Component tools are a perfect solution to this problem. If your plan is to create multiple components, this can get to be pretty cumbersome. Building Web Components can involve a lot of boilerplate code. With development, things are rarely ever ‘simple’. We ended with the code needed to build a basic example. In the last post, we learned about the basics of Web Components. ![]()
