  43. <p>Ebrowser is designed with the philosophy of <a href="https://github.com/torappinfo/uweb">Android uweb browser</a> (<a href="https://gitlab.com/jamesfengcao/uweb">gitlab</a>).</p>
  44. <ul>
  45. <li>lightweight (less than 20k bytes) without bundled electron.</li>
  46. <li>much less memory footprint than edge/chrome browser and highly performant.</li>
  47. <li>keyboard friendly with vim-style keymaps and command line support in address bar.</li>
  48. <li><a href="https://uweb.surge.sh/en/redirect/index.html#">global redirection</a> to bypass censorship.</li>
  49. <li>user CSS/JS at will. Ex. pressing &quot;md&quot; in no-focus mode to preview markdown file.</li>
  50. <li>global CSS/JS for all sites at will.</li>
  51. <li>CSS/JS for domains, similar to <a href="https://jamesfengcao.gitlab.io/uweb/en/sitejs/index.html">uweb</a>, but use sitejs/[domain].js or sitecss/[domain].css, not [domain root].js/css.</li>
  52. <li>customizable.</li>
  53. </ul>
  54. <p>Note: Usually electron apps are heavyweight as they use browsers for simple things. Ebrowser uses core chromium effectively and very lightweight. Recommend to install electron separately.</p>

  65. <p>Later on, you can run &quot;npm install electron&quot; to update electron/chromium or &quot;npm install ebrowser&quot; to update ebrowser independently.</p>

  69. <p>Mirror urls could be used like &quot;:update https://uwebzh.netlify.app/misc/ebrowser&quot;. All the mirrors listed on <a href="https://uwebzh.netlify.app/en/readme/index.html">uweb browser</a> could be used. The update url needs to be changed accordingly to be the folder &quot;misc/ebrowser&quot; under the mirror site root url.</p>
