A brief introduction
First of all, I know, the question is often asked and I have read many discussion before asking. Tipical approches to handle the cache problem that are suggested in other question are:
- Versioning js files in this way:
<script src="/myJavascript.js?version=4"></script>. See Keparo's answer here. - Create a rewrite rule on the web server in this way:
RewriteRule ^(.*)\.[\d]{10}\.(css|js)$ $1.$2 [L]. See Kip's answer here.
Context description
Currently I'm refactoring my old php code running on apache2, introducing an heavy layer of js/jquery to handle the frontend and decoupling FE and BE building some api.
The js project is organized in this way:
my-project/
├── main.js
├── main.css
├── main.php
├── js/
│ ├── JsClass1.js
│ └── JsClass2.js
└── src/
└── php_code/
├── class1.php
└── class2.php
My problem
I don't know how to avoid that js classes are cached from web browser because the previous solution describer in the description are not feasible. Just to make a brief example of my problem this is a portion of code that gives me problems:
main.js
//Import my js classes
import JsClass1 from './js/JsClass1.js';
import JsClass2 from './js/JsClass2.js';
//Instantiate js objects
const j1 = new JsClass1();
const j2 = new JsClass2();
//Use js object
j2.do_stuff();
j2.do_stuff();
JsClass1.js
import JsClassN from "./JsClassN.js";
export default class JsClass1 {
constructor(var1) {
//Create stuff
}
do_stuff() {
//Doing real stuff
}
}
main.php
<!DOCTYPE html>
<html lang='it-IT'>
<head>
<script type='module' src='/main.js?ver=<? echo getVersion(); ?>' type='text/javascript'></script>
</head>
<body>
...
</body>
Wrap up
How can I handle those js imports and avoid that browser caches old classes when I release in production new versions? Do I need to reorganize my code structure to achieve this? And if so, what's the best approach?
