I'll try to break it up as much as possible, but there are plenty of things to be done.

As per the documentation, when working with Flutter Web and Firebase, you need to add your Firebase dependencies in your index.html, like this:

Use the dependencies that you want, but if you aren't using analytics, leave it out. You have to import this first thing though firebasejs/8.3.0/firebase-app.js

Workbox - NetworkOnly executes even if I return false

Asked 2021-May-20 at 19:13

Using Workbox, I am trying to deal with graphql.

Anyone know why I am getting this error message from NetworkOnly? I am returning false in the route matcher, so I don't know why new NetworkOnly() is even executing. This only happens in offline mode (no network available).

The strategy could not generate a response for ... The underlying error is TypeError: Failed to fetch.

ANSWER

Answered 2021-May-20 at 19:13

Sorry about that—you're seeing that behavior because the truthiness of the return value from this function is used to determine whether a route matches, and an async function always returns a Promise, which is a "truthy" value.

There's a log message that warns about this if you're in Workbox's development mode.

If it's possible for you to add in a header on the requests you want to match, that would probably be the easiest way to synchronously trigger your route, since any attempt to access a request body needs to be async. Failing that, the cleanest approach would be to just match all of your GraphQL requests with a given route, and then inside of that route's handler, use whatever async logic you need to trigger different strategies for different types of traffic.

How do I call a function periodically in a manifest v3 Chrome extension?

Asked 2021-Apr-09 at 21:09

Service workers replace background pages in manifest v3 chrome extensions, and I'm trying to use one for my extension. I need to be able to run a function periodically, and it looks like alarms are the way to go. In the example they recommend doing this in the top level of the service worker:

...

ANSWER

Answered 2021-Feb-26 at 19:18

Although it's non-deterministic but the rules are quite simple and the worker behaves almost exactly like the old event page of ManifestV2, the major points are:

it wakes up when a registered API event occurs
it runs the entire script so the API listeners are re-registered
it runs the listener for the API event that woke it
it unloads after 30 seconds (15 in MV2) after the last API event; if another API event is triggered the unload timer is restarted; the timer will be extended by five minutes if there is an open port for chrome.runtime messaging, in MV3 the messaging ports are force-disconnected after five minutes whereas in MV2 these ports never force-disconnect and thus keep the MV2 event page alive.

Now back to that demo script. You're right: it relies on non-deterministic behavior. It's just bad like many examples in the documentation for extensions. Use API reference and devtools debugger.

A more realistic example would be to register an alarm just once, for example in chrome.runtime.onInstalled event, because the alarms are remembered by the browser internally. Also, it's best to give it an id so we can check for its existence:

Subject Alternative Names for Localhost

Asked 2021-Mar-28 at 09:38

I am trying to connect to localhost over https so that I can use service workers. I have tried many solutions such as chrome flags as described in posts such as this, but none have worked. Finally, I used OpenSSL to make myself a certificate authority and sign my own certificate. However, despite everything running correctly Chrome (and other browsers) still rejected my certificate.

This was due to the lack of subject alternative names. I then added my IP address as an alternate name, but it was not accepted either - chrome told me that the "domain came from [IP address]", along with the error message ERR_CERT_COMMON_NAME_INVALID What other subject alternative names can I use to prove my identity over localhost? (or alternatively, are there any other solutions?) I am using Apache with XAMPP.

ANSWER

Answered 2021-Mar-28 at 09:38

The SAN must match the domain in the URL you use. If you use https://localhost then there must be a SAN of type DNS with value localhost. If you use https://127.0.0.1 then there must be a SAN of type IP with value 127.0.0.1. Not the importance of the correct type and not only of the value.

I use localhost as the common name. From my understanding the SAN must be different but still refer to the same domain ...

No. The CN is actually irrelevant and will usually not even be looked at if a SAN is given (or in case of Chrome: it will never look at the CN and requires always SAN). So just make sure that the SAN is correct.

There is no way to pass a FirebaseApp instance (or services taken from that such as the database or auth) between pages. Each web page that loads in a browser is its own instance, and will need to load the Firebase services it uses.

Why service worker restarts only on second load?

Asked 2020-Dec-07 at 15:56

In this docs, I found this snippet:

After the activation step, the service worker will control all pages that fall under its scope, though the page that registered the service worker for the first time won't be controlled until it's loaded again.

I don't think I quite understand this sentence. For me, it seems to mean that:

When the user requests a page, the browser always checks for new service worker (bypassing any cache).
If a new service worker is present - install it and activate it.
Wait for the user to reload the page for the new service worker to take charge.

It doesn't make sense to me. Why make a new service worker take charge only when the user restarts the page, why not make him a primary service worker right away?

...

ANSWER

Answered 2020-Dec-07 at 15:56

Because of consistency as explained in https://developers.google.com/web/fundamentals/primers/service-workers/lifecycle#activate I interpret it as : your user may be filling a form. You don't want the page to change behavior in the middle of his action.

Running flutter web app locally without android studio throws firebase error

Asked 2020-Nov-27 at 20:45

After the successful installation of my flutter web app in a local server (following this answer by using express) I'm able to run my flutter app on localhost. However, upon accessing it, the console displays the error

main.dart.js:28998 Uncaught ReferenceError: firebase is not defined

I presume that I need to install and reference firebase in my app.js but I actually have no idea how it's done (if this is actually the case). I tried running the command npm install firebase which seems to successfully install it however I'm still getting this error.

Do you know what I might be missing or why I am getting this error and how to solve it?

Note that the project works perfectly if ran on Chrome when built using Android Studio so it must be something to do with the local hosting.

This is my current index.html which is working perfectly when I run the project through Android Studio on Chrome

Make sure to include the overall firebase script and the services you're using in your index.html in the web folder. Do it before the line in the body.

Note that even if flutter works well with the index.html as you have it, it's likely that this is the reason why it's not working on your local server.

In your case, move all the firebase related scripts (including the configuration script) before the main.dart.js script:

scripts | description -------------- | ----------- yarn install | install all dev dependencies yarn test | run the test suite yarn run lint| run eslint yarn start | run the demo for development testing. To get started contributing, run yarn start, which will run a webpack-devserver on localhost:3000. In demo/webpack.config.js you’ll see the configurations used for the demo testing. Each experimental config can be accessed via the key query param (i.e. localhost:3000?key=withNotifications). This provides a simple way to install a new service worker for testing, and the corresponding generated code will be visible in the DOM itself thanks to [highlight.js](https://highlightjs.org/). Use the application tab in the devtools to verify that the service worker was installed. By setting debug: true in the plugin config, the devtools console can be used to verify actions are taking place.
