Electron jQuery is not defined

Question

Problem  while developing using Electron  when you try to use any JS plugin that requires jQuery  the plugin doesn t find jQuery  even if you load in the correct path using script tags   For example    lt body gt   lt p id  click-me  gt Click me  lt  p gt       lt script src  node modules jquery dist jquery min js  gt  lt  script gt    jQuery should be loaded now  lt script gt     click-me   click      gt   alert  Clicked      lt  script gt   lt  body gt    Running this code above wouldn t work  In fact  open up DevTools  go to the Console view  and click on the  lt p gt  element  You should see that function   is not defined or something to that effect

electron FAQ answer    http   electron atom io docs faq      I can not use jQuery RequireJS Meteor AngularJS in Electron       Due to the Node js integration of Electron  there are some extra   symbols inserted into the DOM like module  exports  require  This   causes problems for some libraries since they want to insert the   symbols with the same names       To solve this  you can turn off node integration in Electron          In the main process     let win   new BrowserWindow      webPreferences     nodeIntegration  false              But if you want to keep the abilities of using Node js and Electron   APIs  you have to rename the symbols in the page before including   other libraries     lt head gt    lt script gt   window nodeRequire   require   delete window require  delete window exports  delete window module    lt  script gt    lt script type  text javascript  src  jquery js  gt  lt  script gt    lt  head gt

A better and more generic solution IMO              lt  -- Insert this line above script imports  -- gt   lt script gt if  typeof module      object    window module   module  module   undefined   lt  script gt    lt  -- normal script imports etc  -- gt   lt script src  scripts jquery min js  gt  lt  script gt       lt script src  scripts vendor js  gt  lt  script gt        lt  -- Insert this line after script imports -- gt   lt script gt if  window module  module   window module  lt  script gt    Benefits   Works for both browser and electron with the same code Fixes issues for ALL 3rd-party libraries  not just jQuery  without having to specify each one Script Build   Pack Friendly  i e  Grunt   Gulp all scripts into vendor js  Does NOT require node-integration to be false   source here

For this issue  Use JQuery and other js same as you are using in Web Page  However  Electron has node integration so it will not find your js objects  You have to set module   undefined until your js objects are loaded properly  See below example   lt  -- Insert this line above local script tags  -- gt   lt script gt if  typeof module      object    window module   module  module    undefined   lt  script gt    lt  -- normal script imports etc  -- gt   lt script   src  https   code jquery com jquery-3 4 1 min js    integrity  sha256-CSXorXvZcTkaix6Yvo6HppcZGetbYMGWSFlBw8HfCJo     crossorigin  anonymous  gt  lt  script gt        lt  -- Insert this line after script tags -- gt   lt script gt if  window module  module   window module  lt  script gt    After importing like given  you will be able to use the JQuery and other things in electron

Another way of writing  lt script gt window     window jQuery   require    path to jquery    lt  script gt  is      lt script src    path to jquery  onload  window     window jQuery   module exports   gt  lt  script gt

im building and Angular App with electron  my solution was the following      index html    lt script gt      if   typeof module      object   amp  amp  typeof module exports      object            window     window jQuery   require  jquery           lt  script gt       angular json    scripts                    node modules jquery dist jquery min js                  node modules popper js dist umd popper min js                  node modules bootstrap dist js bootstrap min js                  So Jquery gets loaded from angular json if on browser  else if it is an electron builded app it will require module instead   If you want to import jquery in index html instead of importing from angular json use the following solution    lt script src  path to jquery  gt  lt  script gt   lt script gt      if   typeof module      object   amp  amp  typeof module exports      object            window     window jQuery   require  jquery           lt  script gt

As seen in https   github com atom electron issues 254 the problem is caused because of this code   if   typeof module      object   amp  amp  typeof module exports      object           set jQuery in  module    else        set jQuery in  window      The jQuery code  sees  that its running in a CommonJS environment and ignores window   The solution is really easy  instead of loading jQuery through  lt script src       gt   you should load like this    lt script gt window     window jQuery   require    path to jquery    lt  script gt    Note  the dot before the path is required  since it indicates that it s the current directory  Also  remember to load jQuery before loading any other plugin that depends on it

I think i understand your struggle i solved it little bit differently I used script loader for my js file which is including jquery Script loader takes your js file and attaching it to top of your vendor js file it did the magic for me   https   www npmjs com package script-loader  after installing the script loader add this into your boot or application file   import  script path your-file js
