Link with Firestore#

Now we need to link the app with Firestore so we can easily deploy our indexes and rules

firebase init firestore

This command will prompt a few questions

Select to use an existing project
Select the recently created project my-chat-app
On What file should be used for Firestore Rules? press enter
On File firestore.rules already exists. Do you want to overwrite press N
On What file should be used for Firestore indexes? press enter
On File firestore.indexes.json already exists. Do you want to overwrite press N

Afterward the CLI should generate 2 new files .firebaserc and firebase.json containing specifics firebase configs.

Deploy rules and indexes#

Now we can safely deploy Chatness rules and indexes. These are going to be important for the seed step further ahead.

firebase deploy --only firestore:indexes,firestore:rules
