Firebase + React + Vite Step by Step
====================================
This is a step-by-step application using
* [Firebase](https://firebase.google.com/) as the hosting: database,...
* [React](https://react.dev/) for the web application library
* [Vite](https://vitejs.dev/) to setup the application
____________________________________________________________________
React + Vite Initialization
---------------------------
This creates a basic application with [React](https://react.dev/).
First, create github repo on github https://github.com/new.
The repo should be empty (no README, no .gitgnore,...), apart the license file as [Vite](https://vitejs.dev/) will replace existing files.
Then locally
```bash
# Clone the repo locally
git clone git@github.com:pascal-brand38/firbase-react-helloworld.git
# Install Vite if not already done
npm install --global vite
# Create the application
# with project name being firbase-react-helloworld
# and choose "Ignore files and continue"
# and then use React framework, with javascript
npm create vite@latest
# Once created, install it, and push onto gituhub
cd firbase-react-helloworld
npm install
git add .
git commit -s -m 'vite + react'
git push
# Run the app
# and then open your web browser at http://localhost:5173
npm run dev
```
____________________________________________________________________
[Firebase](https://firebase.google.com/) Create and Deploy
----------------------------------------
First, a firebase project must be created on https://firebase.google.com/
```bash
Go to console
# Add a new project
# Name: firbase-react-helloworld
# Do not activate Google Analytics
Add a project
# Prepare to link with your react application
# by adding a web application
# pseudo: firbase-react-helloworld
# and "Configurer également Firebase Hosting pour cette application."
Add the application "web"
```
Once done, run the following locally
```bash
# install firebase and firebase CLI
npm install firebase firebase-tools
# Link your app with the Firebase project
firebase login
firebase init
# and choose, with
# "Hosting: Configure files for Firebase Hosting
# and (optionally) set up GitHub Action deploys"
# and then enter
# then "use an existing project"
# and choose "firbase-react-helloworld"
# ? What do you want to use as your public directory? dist
# ? Configure as a single-page app (rewrite all urls to /index.html)? No
# ? Set up automatic builds and deploys with GitHub? No
# build the react app to create dist directory
npm run build
# deploy on https://firbase-react-helloworld.web.app/
firebase deploy
# save on git
git add .
git commit -s -m 'firebase'
git push
```
____________________________________________________________________
[Firebase](https://firebase.google.com/) Use in the application
----------------------------------------
In App.jsx, use the following:
```js
import { initializeApp } from "firebase/app"
const [app, setApp] = useState(undefined)
useEffect(() => {
const init = async() => {
const firebaseConfig = { // is found in the firebase application parameters
apiKey: "AIzaSyAggx6E7Q6ttCUI2Lkexf6xz4VvtiPNUZc",
authDomain: "firbase-react-helloworld.firebaseapp.com",
projectId: "firbase-react-helloworld",
storageBucket: "firbase-react-helloworld.appspot.com",
messagingSenderId: "597188741887",
appId: "1:597188741887:web:fa6a8203246efeed77daca"
};
// Initialize Firebase
const app = initializeApp(firebaseConfig);
setApp(app)
}
init()
}, [])
```
____________________________________________________________________
Firestore Database
------------------
### Database creation
Go on https://firebase.google.com, then ```go to the console```, and then select the project (firbase-react-helloworld)
Then click on ```Create / Firestore Database```, and then ```Create a database``` and ```Démarrer en mode test```
Then ```Create a new collection```
* called stats
* with document id being count
* with 1 field: count, a number initialized at 0
### Database usage in the Application
You can refer at [Google documentation](https://firebase.google.com/docs/firestore/query-data/get-data?hl=fr).
#### Use the Database
In App.jsx, use the following:
```js
import { getFirestore } from "firebase/firestore"
import { doc, getDoc, setDoc } from "firebase/firestore"
const [db, setDb] = useState(undefined)
useEffect(() => {
const init = async() => {
const db = getFirestore(app);
setDb(db)
if (docSnap.exists()) {
console.log("Document data:", docSnap.data());
setCount(docSnap.data().count) // read the database
} else {
// docSnap.data() will be undefined in this case
console.log("No such document!");
}
}
init()
}, [])
// Read a value from the database
const docRef = doc(db, "stats", "count");
const docSnap = await getDoc(docRef);
// Write a value to the database
setDoc(docRef, { count: newCount }, { merge: true });
```
Authentication
--------------
Several [authentication methods](https://firebase.google.com/docs/auth/where-to-start?authuser=0&hl=fr) exist in Firebase, such as the [Authentication Email/Password](https://firebase.google.com/docs/auth/web/password-auth?authuser=0&hl=fr).
In order to use email/password authentication, ```go to the console``` and
your project, then ```Create Authentication```, then ```Email/Password```, and finally ```Activate```.
To create a new user
```js
import { getAuth, createUserWithEmailAndPassword } from "firebase/auth";
const auth = getAuth();
createUserWithEmailAndPassword(auth, email, password)
.then((userCredential) => {
// Signed up
const user = userCredential.user;
// ...
})
.catch((error) => {
const errorCode = error.code;
const errorMessage = error.message;
// ..
});
```
To connect
```js
import { getAuth, signInWithEmailAndPassword } from "firebase/auth";
const auth = getAuth();
signInWithEmailAndPassword(auth, email, password)
.then((userCredential) => {
// Signed in
const user = userCredential.user;
// ...
})
.catch((error) => {
const errorCode = error.code;
const errorMessage = error.message;
});
```
Storage
=======
In the Firebase console, create a Storage, a directory
```Public``` in the storage, and finally upload a file there.
In the rules tab of the console, create the following rule to
indicate that anything inside the public folder is read-only:
```
rules_version = '2';
service firebase.storage {
match /b/{bucket}/o {
match /public/{file} {
allow read;
allow write: if false;
}
}
}
```
And finally configure the storage to be accessed whatever is the IP:
```bash
pacman -S mingw-w64-x86_64-python-gsutil
python -m pip install requests
cat <<< EOF >>> cors.json
[
{
"origin": ["*"],
"method": ["GET"],
"maxAgeSeconds": 3600
}
]
EOF
gsutil cors set cors.json gs://firbase-react-helloworld.appspot.com
```
In your application, use the following to get the url access of a file,
to be run once the app initialization is performed:
```js
import { getStorage, ref, getDownloadURL } from "firebase/storage";
const storage = getStorage();
const imgRef = ref(storage, 'public/firebase-cloud-storage.png');
getDownloadURL(imgRef)
.then((url) => {
// Insert url into an ![]()
tag to "download"
console.log('PASCAL url ', url)
setUrl(url)
})
.catch((error) => {
// check https://firebase.google.com/docs/storage/web/download-files?hl=fr
// and https://firebase.google.com/docs/storage/web/handle-errors
console.log(`STORAGE ERROR ${error}`)
})
```
