Using Firebase and Firestore with NextJS and Docker - Part 1 - Setup firebase in docker

Last year, I got a case to use firebase and firestore with Next.js. I’ve been fullstack many years, so I haven’t tried to use firebase and firestore. There was a great chance to give it a try.

In this article I’ll show how to use firebase and firestore in Docker and Next.js. If you don’t have backend support, or you don’t want to build whole backend, database, and infrastructure, you would probably think this is a useful way.

Create a firebase project

Let’s start it. Go to firebase console and follow the step to create a new project.

It is just for demo, so I uncheck google analytics in step 2.

A few minutes later, it shows you the firebase console. Next we have to add firebase to webapp by clicking the button.

We just need to focus on Step 1 and Step 4 in the following image, because we step 2 config you can get it from project setting again and step 3 we will use docker later.

step 4 commands:

• firebase login
• firebase init
• firebase deploy

After creating firebase app, we have to create firestore database for our app (we use test-mode and locale use asia-east1):

Cool, but in this article we won’t show how to create a nextjs project and setup docker-compose, you can find it in my previous blog. Then, let’s add firebase docker to docker-compose.

Add firebase to docker-compose

Instead of npm install -g firebase-tools, we use docker-compose. The following code shows how to integrate firebase-tools to docker-compose.

version: '3.8'
services:
  frontend:
    container_name: frontend
    build:
      context: .
      dockerfile: Dockerfile
    volumes:
      - ./app:/app
      - ./app/node_modules:/app/node_modules
    command: sh -c 'npm start'
    ports:
      - "3000:3000"
    stdin_open: true
  firebase:
    container_name: firebase
    image: andreysenov/firebase-tools
    user: node
    #command: firebase emulators:start
    command:·tail·-f·/dev/null
    ports:
      - 9005:9005
      - 9099:9099
      - 9199:9199
      - 5001:5001
      - 5000:5000
      - 8080:8080
      - 8085:8085
      - 9000:9000
      - 3003:3003
      - 4000:4000
    volumes:
      - ./:/home/node

Look at our file structure:

You can type docker-compose build to build docker container now. And don’t forget to install npm into app: docker-compose run --rm frontend npm install

Before we firebase login and firebase init, use command: tail -f /dev/null. Once we have firebase.json we can use command: firebase emulators:start.

Okay, after docker-compose up, try to use firebase-tool to login first:

docker-compose exec firebase firebase login docker-compose exec firebase firebase init

If you get this message: Error: It looks like you haven’t used Cloud Firestore in this project before. Please check your Default GCP resource location in Project Setting.

By the way, notice these two questions:

1. ? What do you want to use as your public directory? app/build
2. ? Configure as a single-page app (rewrite all urls to /index.html)? Yes

It’s almost done. We have to add host: 0.0.0.0 to each service of emulators in firebase.json:

    "firestore": {
      "host": "0.0.0.0",
      "port": 8080
    },
    "database": {
      "host": "0.0.0.0",
      "port": 9000
    },
    "hosting": {
      "host": "0.0.0.0",
      "port": 5000
    },
    "storage": {
      "host": "0.0.0.0",
      "port": 9199
    },
    "ui": {
      "enabled": true,
      "host": "0.0.0.0",
      "port": 4000
    },
    "singleProjectMode": true

Time to comment and uncomment our command part in docker-compose.yml, and restart docker-compose up. Yeah! After clicking http://localhost:4000/, we’ll see the result!

Okay! Firebase is ready for our project. Next artile we will demostrate how to use firebase with Next.js!
