A Single File Web App (SFWA) is a type of Single-Page App (SPA) that it is composed of only a static HTML file with no external dependencies (including external images, JavaScript, CSS, etc), and no server components (with the exception of an HTTP Server). Note that the HTML file can have javascript, css, and images - as long as they are embedded in the singular HTML file.[1].
Overview
[edit]Single File Web Apps are designed to run entirely offline or in isolation, with every resource (HTML, CSS, JavaScript, images, and fonts) embedded directly into a single HTML file. This makes them uniquely portable and easy to distribute. Users can simply download the file and open it in a browser without any installation or hosting setup.
Features
[edit]- Self-contained - all assets included directly within the file.
- Durable - since Single File Web Apps have no external dependencies or server components, they are more resistant to Software rot than most other types of software [2]
- Portable - can be distributed by email, USB stick, or local file sharing.
- Offline-friendly - works without an internet connection once downloaded.
- Simple deployment - just drop the file onto any static file host, such as GitHub Pages or a local filesystem.
Identification
[edit]In order to identify if a web app is a Single File Web App, you can perform the following steps:
- Navigate to the web app, and after it loads, save the web page to your desktop ("HTML only" if given the option) by going to File -> Save Page As (or the equivalent menu name in your browser).
- Turn off your internet
- Navigate to the HTML file on your desktop, and double-click on it to open it (or open it your browser by going to File -> Open File).
- Test that the app works fully while you are disconnected from the internet. If it does, then it's a SFWA. If it does not work while disconnected from the internet, then it is not a SFWA.
Examples
[edit]- TiddlyWiki[3] - a "highly customizable non-linear personal notebook and wiki that runs entirely in a single HTML file"
- FuzzyGraph[4] - "a non-binary graphing calculator in a single html file."
- Hypervault[5] - a "personal computing platform in a single html file."
- Slingcode[6] - "a file encryption app in a single html file."
- A collection of single file web apps can be found here[7]
