Before You Begin 🎯 Before you start, there are a few prerequisites you need to take care of: **Add Firebase to Your Project**: If you haven’t done so already, you need to add Firebase to your project. You can follow the steps in this [link](https://firebase.google.com/docs/web/setup) to get started 🎉. **Upgrade to the Blaze Plan**: The JustPass Firebase extension requires the Blaze (pay as you go) plan. If you haven’t upgraded your project yet, you should do so now. **Install or Update the Firebase CLI**: The Firebase CLI allows you to install and manage Firebase extensions from the command line. Make sure you have the latest version installed. **Enable Cloud Storage**: The JustPass Firebase extension requires Cloud Storage to be enabled for your project. You can check if it’s enabled from this [link](https://console.cloud.google.com/apis/api/firestore.googleapis.com/overview). **Find Your Firebase Project ID or Alias**: You will need either your Firebase project ID or a previously configured project alias to install the extension. You can run the appropriate command from your local app directory to find these. **Get Your JustPass Keys**: Go to the JustPass.me Dashboard and copy the following keys. You will need them to configure the extension: — JUSTPASSME_ORGANIZATION_NAME — JUSTPASSME_ID — JUSTPASSME_API_SECRET Step 1: Installing the Extension Once you have taken care of the prerequisites, you can proceed to install the JustPass Firebase extension. Here’s how you do it: **Set up an Empty Extensions Manifest**: Run the following command to set up an empty Extensions manifest: firebase ext:dev:init 2. **Install the Extension**: Run the following command to install the JustPass Firebase extension: firebase ext:install justpassme/firebase-extension --project=Replace \\ with your actual Firebase project ID.` Step 2: Deploying the Extension ✅ After you have installed the JustPass Firebase extension, you can deploy it to your Firebase project by running the following command: firebase deploy — only extensions` You have now successfully added passkeys authentication to your Firebase project using the JustPass Firebase plugin 🎉 ✅. Make sure to keep it safe, as you’ll need it for granting access to users. If you have any questions or run into any issues, feel free to reach out to [email protected] for assistance. Happy coding! 💪

Auth persistence Issue Firebase SDK - https://github.com/firebase/firebase-js-sdk/issues/6050

Connecting to firebase is as simple as copying and pasting the credentials (that Firebase gives you) into your frontend app. Here is a link to the documentation. If you need help, simply make a more detailed post about the issues you are running into.

Similarly to Promises/A+, this effort focuses on aligning the JavaScript ecosystem. If this alignment is successful, then a standard could emerge, based on that experience. Several framework authors are collaborating here on a common model which could back their reactivity core. The current draft is based on design input from the authors/maintainers of Angular, Bubble, Ember, FAST, MobX, Preact, Qwik, RxJS, Solid, Starbeam, Svelte, Vue, Wiz, and more…

RxJS is used for events and asynchronous tasks

Data flowing like a melody? Master RxJS, the reactive JavaScript library, to handle asynchronous data flows with grace and ease. Streamlined data, happy code.

> This proposal makes the same mistake as various stream implementations (including RxJS in the past) of making operators methods on the observable.

I don't think they are making a mistake. I am sure Ben knows what he is doing, given how it was he who refactored rxjs 5 with all operators being methods on the Observable, to rxjs 6 with pipeable operators.

But, their objective is not to bring rxjs into the browser, but rather to bring the Observable primitive into the browser. And, like Array prototype, which has methods, Observable, in order to be even minimally useful, needs some methods, which they modelled from TC39 iterators, for the sake of consistency.

They say:

> We expect userland libraries to provide more niche operators that integrate with the Observable API central to this proposal, potentially shipping natively if they get enough momentum to graduate to the platform. But for this initial proposal, we'd like to restrict the set of operators to those that follow the precedent stated above, similar to how web platform APIs that are declared Setlike and Maplike have native properties inspired by TC39's Map and Set objects. Therefore we'd consider most discussion of expanding this set as out-of-scope for the initial proposal, suitable for discussion in an appendix. Any long tail of operators could conceivably follow along if there is support for the native Observable API presented in this explainer.

As to

> We really need a `pipe` operator, at minimum

Maybe we don't. Note that in RxJS version 8, they have introduced a new way of piping observables, which is the rx function [0]. Maybe they are thinking of something similar for the browser. Or maybe they are thinking of using the native pipeline operator if it ever gets approved.

In the meantime, for any complex manipulations on observables, users will probably still import relevant functions from libraries.

Signal Store helps to streamline your usage of RxJS and Signals: e.g. connect and rxEffect understand both Signals and Observables

Our bus event is really simple in fact. We have declared into the core module (provided in all the application) an rxjs Subject.

Web scraping may seem like a simple task, but there are many challenges to overcome. In this blog, we will dive into how to scrape LinkedIn to extract job listings. To do this, we will use Puppeteer and RxJS. The goal is to achieve web scraping in a declarative, modular, and scalable manner.
