Usage

injectCSS(cssFile)

Franz currently uses the webviews API to inject the CSS file. This makes it necessary to add the !important flag to the CSS attributes you like to override.

Arguments

1. string cssFile

• CSS files that should be injected. This must be an absolute path to the file

Usage

const path = require('path');

// inject a single css file
Franz.injectCSS(path.join(__dirname, 'style.css'));

// inject multiple css files
const globalStyles = path.join(__dirname, 'global.css');
const focusModeStyles = path.join(__dirname, 'focusmode.css');

Franz.injectCSS(globalStyles, focusModeStyles);

loop(action)

Runs an action every X milliseconds (Franz default is currently 1s)

Arguments

1. function action

Usage

// slack integration
const path = require('path');

module.exports = (Franz, options) => {
  const getMessages = () => {
    const directMessages = $(".unread_highlights, .unread_highlight").not(".hidden").length;
    const indirectMessages = $(".unread").length - directMessages;

    Franz.setBadge(directMessages, indirectMessages);
  }

  Franz.loop(getMessages);
