Module functions 

Firebase Functions

The functions module provides a Rust port of the Firebase Cloud Functions (client) SDK so applications can invoke HTTPS callable backends from native or WASM targets. The goal is to mirror the modular JavaScript API (@firebase/functions) while using idiomatic Rust primitives.

Quick Start Example

use firebase_rs_sdk::app::initialize_app;
use firebase_rs_sdk::app::{FirebaseAppSettings, FirebaseOptions};
use firebase_rs_sdk::functions::{get_functions, register_functions_component};
use serde_json::{json, Value as JsonValue};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    register_functions_component();

    let app = initialize_app(
        FirebaseOptions {
            project_id: Some("demo-project".into()),
            ..Default::default()
        },
        Some(FirebaseAppSettings::default()),
    )
    .await?;

    let functions = get_functions(Some(app.clone()), None).await?;
    let callable = functions
        .https_callable::<JsonValue, JsonValue>("helloWorld")?;

    let response = callable
        .call_async(&json!({ "message": "hi" }))
        .await?;
    println!("response: {response:?}");
    Ok(())
}

Use your platform’s async runtime to drive the main future (for example #[tokio::main] on native targets or wasm_bindgen_futures::spawn_local on wasm32-unknown-unknown).
