I'm integrating an existing React app into Next.js for mainly SEO features.
i pasted the css files links inside the <Header> tag in Next.js and they seem to work just fine. when i tried to do the same with the javascript files using the <script> tag, it doesn't execute the code inside those scripts. but i can see them loaded with http 200 in the chrome dev tools.
I tried using a library called Loadjs from npm to load the scripts inside componentDidMount but i got the exact same result as using <script> tag.
is there a proper way to do such simple thing in Next.js that i'm not aware of ?
Here's the code included in the pages/index.js file.
import React from "react"
import Head from 'next/head'
import MyAwesomeComponent from "../components/mycomponent.js"
export default () => (
<div>
<Head>
<link type="text/css" rel="stylesheet" href="static/css/chatwidget.css" />
<link type="text/css" rel="stylesheet" href="static/css/download.css" />
<script type="text/javascript" src="static/libs/jquery.min.js"></script>
<script type="text/javascript" src="https://cdn.jsdelivr.net/npm/[email protected]/jquery.mCustomScrollbar.concat.min.js"></script>
<script type="text/javascript" src="static/libs/bootstrap.min.js"></script>
<script type="text/javascript" src="static/libs/owl.carousel.min.js"></script>
<script type="text/javascript" src="static/scripts/chatHead.js"></script>
<script type="text/javascript" src="static/libs/jquery.magnific-popup.js"></script>
</Head>
<MyAwesomeComponent /> {/* a simple React component that returns : <p>Hello World </p>*/}
</div>
)
Sorry for the late answer.
it turned out that all the scripts i linked missed one script that would actually run the functions for each action.

Although NextJS is developing rapidly and many features arrive, it still has some cons and issues which you can see below: Cost of flexibility – Next JS does not provide many built-in front pages, so you have to create the whole front-end layer from the ground up.
The “script” tag JavaScript programs can be inserted almost anywhere into an HTML document using the <script> tag. You can run the example by clicking the “Play” button in the right-top corner of the box above. The <script> tag contains JavaScript code which is automatically executed when the browser processes the tag.
“js file not loading in html” Code Answer Most likely, the problem is that you are including your js file in a head tag or somewhere above your main content. ... You should be able to add the js file in a script tag. The page loads first then JavaScript.
Next. js supports lazy loading external libraries with import() and React components with next/dynamic .
This works to me:
Create a folder for your static files:
<root>/static/hello.js
in your index.js
<root>/pages/index.js
import Head from 'next/head';
import MyAwesomeComponent from '../components/mycomponent';
export default () => (
<div>
<Head>
<script type="text/javascript" src="/static/hello.js"></script>
</Head>
<MyAwesomeComponent />
</div>
)
Hope this help,

With the below approach you can easily put a script file's raw script text into a generated Next.js HTML page's <head> without screwing around with character escaping, formatting and general pretending that we aren't actually just building an HTML page in the end anyways.
There are many use cases you may want a script to run without going to network. Ex: 3rd party scripts, monitoring / analytics scripts that expect to be in the <head> without a separate network load. Many of these come minified, mangled, you-name-it and are just supposed to be copy, paste, move on with life.
Next.js makes this very hard pretending that everything with web development is magically React and Webpack all the time now (I wish right?)
The best developer experience way I've found is to do this:
_document.js
...
<Head>
<script type="text/javascript" dangerouslySetInnerHTML={{ __html: process.env.rawJsFromFile }}></script>
</Head>
...
next.config.js
https://github.com/vercel/next.js/blob/canary/packages/next/next-server/server/config.ts#L33
module.exports = {
env: {
rawJsFromFile: fs.readFileSync('./rawJsFromFile.js').toString()
}
}
rawJsFromFile.js
alert('Freedom!!!!!!!!!!!!!!!');
// and other 3rd party script junk, heck even minified JS is fine too if you need
Hope this saves someone from hours of frustration that I endured coming up with this... 😭
