[laravel] how to add jquery in laravel project

I am new to laravel framework. I want to use jQuery in web application built using laravel framework.

But don't know how to link to jQuery library in laravel project.

In Laravel 6 you can get it like this:

try {
    window.$ = window.jQuery = require('jquery');
} catch (e) {}

To add jquery to laravel you first have to add the Scaffolded javascript file, app.js

This can easily be done adding this tag.

<script src="{{ asset('js/app.js') }}"></script>

There are two main procesess depending on the version but at the end of both you will have to execute:

npm run dev

That adds all the dependencies to the app.js file. But if you want this process to be done automatically for you, you can also run:

npm run watch

Wich will keep watching for changes and add them.

Version 5.*

jQuery is already included in this version of laravel as a dev dependency.

You just have to run:

npm install

This first command will install the dependencies. jquery will be added.

Version 6.* and 7*

jQuery has been taken out of laravel that means you need to import it manually.

I'll import it here as a development dependency:

npm i -D jquery

Then add it to the bootstrap.js file in resources/js/bootstrap.js You may notice that axios and lodash are imported there as well so in the same way we can import jquery.

Just add wherever you want there:

//In resources/js/bootstrap.js
window.$ = require('jquery');

If you follow this process in the 5.* version it won't affect laravel but it will install a more updated version of jquery.

You can link libraries from cdn (Content delivery network):

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css">
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap-theme.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/js/bootstrap.min.js"></script>

Or link libraries locally, add css files in the css folder and jquery in js folder. You have to keep both folders in the laravel public folder then you can link like below:

<link rel="stylesheet" href="{{asset('css/bootstrap-theme.min.css')}}">
<script src="{{asset('js/jquery.min.js')}}"></script>

or else

{{ HTML::style('css/style.css') }}
{{ HTML::script('js/functions.js') }}

If you link js files and css files locally (like in the last two examples) you need to add js and css files to the js and css folders which are in public\js or public\css not in resources\assets.

For those using npm to install packages, you can install jquery via npm install jquery and then use elixir to compile jquery and your other npm packages into one file (e.g. vendor.js). Here's a sample gulpfile.js

var elixir = require('laravel-elixir');

elixir(function(mix) {
    mix

    .scripts([
        'jquery/dist/jquery.min.js',
        // list your other npm packages here
    ],
    'public/js/vendor.js', // 2nd param is the output file
    'node_modules')        // 3rd param is saying "look in /node_modules/ for these scripts"

    .scripts([
        'scripts.js'       // your custom js file located in default location: /resources/assets/js/
    ], 'public/js/app.js') // looks in default location since there's no 3rd param

    .version([             // optionally append versioning string to filename
        'js/vendor.js',    // compiled files will be in /public/build/js/
        'js/app.js'
    ]);

});
