Glossary of Important Terms
Single File Component (SFC)
A single file component is a component that is defined in a single file.
Enhance SFCs are called Elements and reside in the
This is made possible by Enhance’s built-in rendering engine.
Scoped styles are styles that are scoped to a specific component.
This means that the styles will only apply to the component and its children.
Scoped styles are defined in the
<style> tag of an element.
Cloud functions are serverless functions. See FWA below.
Web Component (WC)
A Web Component is a set of web platform APIs that allow you to define custom elements and their behavior, which can then be used in your web pages and web apps. The APIs consist of Custom Elements, Shadow DOM, HTML Templates, and HTML Imports.
Shadow DOM is a sub-set of the Web Component standards that allow you to attach a set of DOM nodes to an element, and keep those DOM nodes separate from the main document DOM.
This lets you author code that is effectively private to the component.
Enhance does not make use of Shadow DOM, but does not limit its usage in your components’ browser code.
ES Modules (ESM)
They are supported in all modern browsers and Node.js.
Enhance uses the
.mjs file extension to indicate to the Node.js runtime that the file is an ES Module.
It is most common in Node.js environments.
Enhance projects very rarely include CommonJS modules.
Projects and Organizations
Functional Web App (FWA)
Functional Web App (FWA) is an architectural pattern for building web applications and APIs. It empowers developers with the flexibility of dynamic, full-stack applications paired with the ease of scaling a static website.
Cloud functions (aka “serverless”) + managed database + deterministic deployment
An orchestration framework with strong conventions for building Functional Web Apps.
Arc offers many FWA primitives and has a robust plugin API.
Architect apps target AWS for deployment.
A build-less, HTML-first web application framework; implemented as an Architect plugin.
Enhance is mostly a web server that focuses on web standards (Web Components in particular), to enable powerful and accessible browser experiences.
Enhance is an Arc plugin with its own conventions, driven by Arc authors solidifying how they build web apps into a framework.
Begin.com is a cloud provider, specialized in the deployment of Architect FWA projects with an emphasis on Enhance-powered applications.
