Draft:Single File Web Apps

From Wikipedia, the free encyclopedia


A Single File Web App (SFWA) is a type of Single-Page App (SPA) that it operates entirely as a self-contained client-side application with no server component and no external dependencies (including external images, JavaScript, CSS, etc).

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.

Key characteristics

[edit]
  • No server component – runs purely in the browser.
  • Self-contained – all assets included directly within the file.
  • 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.

Use cases

[edit]

Single File Web Apps are often used for:

  • Building highly portable and durable apps
  • Building apps that run entirely offline in the browser sandbox (for additional security)
