A Node.js CLI tool that captures responsive snapshots of a website, generating images for multiple viewport sizes. This allows developers to quickly test and visualize how their web pages appear across different devices and browsers, from mobile to desktop, streamlining the process of ensuring a responsive design.
NOTE: Animations on a website may produce various different results on the images.
Option 1: Use directly with npx
npx viewsnap generate <url>
Option 2: Install viewsnap package globally
npm install -g viewsnap
viewsnap generate <url>
Option 3: install to project scope, and add the command to PATH variable
npm install viewsnap --save-dev
Add the viewsnap command to PATH variable:
export PATH=$PATH:$(npm bin -g)
viewsnap generate <url>
Snapshots and an overview page snapshots.html are stored in .viewsnap directory.
The generate command takes snapshots of a website URL given as a parameter. Snapshots are taken with multiple viewport sizes covering the most common device viewports from desktop, tablet, and mobile devices. Viewport snapshots are taken with three different headless browsers (Chrome, Firefox, WebKit).
Syntax:
viewsnap generate <url> [options]
URL
- URL for a website, can be local or web-hosted
Options
- -f, --full-height, option sets the viewport height for full height of the page.
Example output:
npm viewsnap generate http://localhost:5137
