Learning Firebase Local Emulator Suite
Just one of the things I'm learning. https://github.com/hchiam/learning
https://firebase.google.com/docs/emulator-suite/connect_and_prototype
https://firebase.google.com/docs/emulator-suite/connect_firestore
Testing out this repo
After you clone this repo to you local machine, run these CLI commands: (no need to npm install first)
cd learning-firebase-local-emulator
npm i -g firebase-tools
firebase init
Very basic setup from scratch
curl -sL firebase.tools | bash
# firebase logout
# firebase login
firebase init # I personally chose the firestore and emulators option, and opted out of using a default project
# you might have to
firebase login --reauth
and then:
firebase emulators:start

npm i -g firebase-tools
firebase --version
# firebase logout
# firebase login
firebase init
firebase emulators:start # localhost:4000
firestore.doc("hello/world").set({ hello: "world!" });
firestore
.doc("hello/world")
.get()
.then((snap) => console.log(snap.data()));
firebaseConfig = {
projectId: ...your-project-id-here...,
};
firebase.initializeApp(firebaseConfig);
database = firebase.firestore();
if (location.hostname === "localhost") {
// to use the emulator instead of the real DB:
database.useEmulator("localhost", 8080);
}
To backup and reuse local data of the running emulator:
firebase emulators:export seed
# (remember the export path)
# (and then upon restarting the emulator:)
firebase emulators:start --import seed
You might also find interesting:
firebase emulators:start --import seed --export-on-exit=seed
# see it repopulated at http://localhost:4000/firestore
