Chefies Backend

Backend of Chefies Project made with Python and FastAPI. This is being made as a requirements to complete the Bangkit capstone project.

Development Environment Installation

Requirements

Before installing, you need python and poetry to be installed in your computer. You can follow these guidelines:

• Python Installation
• Poetry Installation

Installing Dependencies

In the project root directory where pyproject.toml and poetry.lock is located, run:

poetry install

This command will install required dependencies for running the backend application.

Firebase Emulators

This project requires several GCP technologies such as Cloud Storage, Cloud Firestore, and Gemini API. For Cloud Storage and Cloud Firestore, you can use firebase emulators to run them in local. Follow this firebase emulators installation guideline. For Gemini API, you need to enable Generative Language API in your GCP project and get a service account key that is capable to use the API.

To start the emulators, run the command below.

firebase emulators:start

Running the Backend

Before running the FastAPI backend, ensure that you have included these environment variables in the .env file:

• FIRESTORE_EMULATOR_HOST: The host of firestore emulator. Using the given firebase.json config, the value must be localhost:8080
• STORAGE_EMULATOR_HOST: The URL of storage emulator. Using the given firebase.json config, the value must be http://localhost:9199
• GOOGLE_APPLICATION_CREDENTIALS or SERVICE_ACCOUNT_PATH (choose one): Path of the service account key. Example: keys/credentials.json
• STORAGE_BUCKET: Storage bucket name in Cloud Storage. Example: chefies-dev.appspot.com

Now, you can run the backend in port 8000 using this command:

poetry run fastapi run cefies/app.py --port 8000

Deployment

We have created a Dockerfile for deploying the application in Docker containers. To build the image, you can use:

docker build -t <image-name> .

After building the image, you can run it by using:

docker run --name <container-name> -e PRODUCTION=1 -e GOOGLE_APPLICATION_CREDENTIALS=<credentials-json-path> -d --restart always -p 9000:80 <image-name>

Note that the env FIRESTORE_EMULATOR_HOST and STORAGE_EMULATOR_HOST is not required as you are not using firebase emulators.
