jQuery導入

Posted at

今回は、JavaScriptのjQuerykの導入のみの記事です!
ネットで調べても中々うまくできなかったので、、、

※jQueryの導入には、jquery-railsというGemを利用することもあります!
今夏は違う方法です

##◇jQueryをインストール

ターミナル
% yarn add jquery

##jQueryを管理化に

config/webpack/environment.js 
const { environment } = require('@rails/webpacker')
const webpack = require('webpack')

environment.plugins.prepend('Provide',
  new webpack.ProvidePlugin({
    $: 'jquery',
    jQuery: 'jquery',
    jquery: 'jquery',
  })
)

module.exports = environment

##jQueryを認識させる??

 app/javascript/packs/application.js
require('jquery')

##下記内容は記述されてればそのままで!

 app/views/layouts/application.html.erb
<%= javascript_pack_tag 'application', 'data-turbolinks-track': 'reload' %>

これでjQuery使えます!

以上
