VistasLoading service worker behind authentication
I have developed a javascript application with a custom service worker and facing a problem fetching the service worker file behind authentication.
My application is deployed behind a cookie based authentication (after login, the user has a cookie which is checked by every request). This is fine for for fetching all resources, except the service-worker file, which the browser doesn't doesn't send any cookies.
Here is miminal example reproducing my issue:
backend: index.js
// Service worker file
app.get('/test.js', (req,res) => {
if(req.cookies.token != null) {
res.sendFile('./public/test.js')
}
else {
res.sendStatus(401)
}
})
// Index page
app.get('/', (req, res) => {
// initial login check goes here
res.cookie('token',"<user token>").sendFile('./public/index.html')
})
frontend: index.html
<body>
<h1>Test</h1>
// Doesn't work with the auth
<script>
const registration = await navigator.serviceWorker.register('test.js')
console.log(registration)
</script>
// Works with the auth
<script src="test2.js"></script>
</body>
When the request is made, the browser doesn't attach any cookie information:
.
Why doesn't the browser treat the service-worker request as everything else? Am I missing a flag similiar to fetch credentials option?
