Unofficial Wasm bindings for [Firebase](https://firebase.google.com) JS SDKs written in Rust.
## Get strted
Following example shows how to add email and password sign in to [Sycamore](https://sycamore-rs.netlify.app) app.
### Add and initialize SDK
Install firebase-js-rs by running the following Cargo command in your project directory:
```
cargo add firebase-js-rs
```
or alternatively add the following line to your Cargo.toml:
```toml
firebase-js-rs = "0.1.1"
```
Then add project in the [Firebase console](https://console.firebase.google.com/?authuser=0) and install JS SDKs from the CDN.
```html
```
### Initialize Firebase app and get reference to the authentication service
```rust
use sycamore::prelude::*;
use firebase_js_rs::{app::initialize_app, Config};
fn main() {
sycamore::render(|cx| {
view! { cx,
// Initialize Firebase
let firebase_app = initialize_app(Config::initialize(
"api_key", None, None, None, None, None, None,
));
// Get reference to the auth service
let auth = app.auth();
}
});
}
```
### Create new user
```rust
let result = auth.create_user_with_email_and_password(email, password).await;
```
### Sign in user
```rust
let result = auth.sign_in_with_email_and_password(email, password).await;
```
### Observe authentication state
```rust
let callback = Closure::new(move |user: JsValue| {
// Get info about user
});
auth.on_auth_state_changed(&callback);
callback.forget();
```
