If you have a Rust server and plan to have API for your verifying your firebase users' client token, then it's just for you!

It only contains small utility to decode your client token.

Flow

  1. In your frontend, you can get your uid + client-token by using Firebase Client SDK.

    Sample: https://firebase.google.com/docs/auth/admin/verify-id-tokens#retrieveidtokensonclients

  2. Then your frontend can hit the backend Rust API and send over uid+client-token to the HTTP Header/POST body (up to you), which will be passed to verify_token(uid, client_token) util.

  3. Add FIREBASE_PROJECT_ID environment variable to your backend on local and production server

  4. Backend Rust will verify and send back the JWL claim response (including extracted user's data) back as json

How to use

```rs use firebasejwtrs::*; use jsonwebtoken::TokenData; use std::error::Error;

let uid = "your-user-uid"; let client_token = "your-client-token";

const result: Result, Box> = verifytoken(uid, clienttoken);

match result { Ok(res: TokenData) => { let text: String = serdejson::tostring(&res.claims).unwrap(); println!("result:{text}"); } Err(e) => { println!("err:{e}"); } } ```
