how to add jquery in laravel project

you can use online library

<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 else download library and add css in css folder and jquery in js folder.both folder you keep in 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') }}

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'
    ]);

});

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

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.

Laravel 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.

Laravel 6.* , 7.* and 8.*

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

npm i 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.
