Dynassets

Dynassets creates a simple server to serve static files like JavaScript, CSS etc. with specific delay.

E.g.

http://localhost:3000/asset/js/3000 would serve a JavaScript file that would take at least 3s before the 1st byte to return.

Use this to create HTMl pages with different delay value on different assets to check their impact on load-time performance in different browser.

E.g.

Load up a web font with 5s delay to see how different browsers behaves when waiting for the font to download.

Load up a CSS in different parts of HTML with 2s delay to see how it impacts rendering in different browsers.

I needed a quick way to generate different kinds of static files with different delay values to understand how different browsers handle them and how it impacts the application that I create. And the result is dynassets

Installation

$ npm i dynassets -g

Usage

$ dynassets

Now, you can start using delayed assets in your templates.

E.g.

• Javascript: http://localhost:3000/js/1000
• Stylesheet: http://localhost:3000/css/1000
• Font: http://localhost:3000/font/1000 (Serves Roboto font from Google)
• Image: http://localhost:3000/image/1000 (Serves random image from lorempixel)

If you need to use a different port number:

$ dynassets -p 3001

If you need to serve assets on a url reachable via the internet

$ dynassets -t
