Fireorm is a tiny wrapper on top of firebase-admin that makes life easier when dealing with a Firestore database. Fireorm tries to ease the development of apps that rely on Firestore at the database layer by abstracting the access layer providing and familiar repository pattern. It basically helps us not worrying about Firestore details and focusing in what matters: adding cool new features!

You can read more about the motivations and features of fireorm on its introductory post. Also, the API documentation is available.

Usage

  1. Install the npm package:
yarn add fireorm reflect-metadata #or npm install fireorm reflect-metadata

# note: reflect-metadata shim is required
  1. Initialize your firestore application:
import * as admin from 'firebase-admin';
import * as fireorm from 'fireorm';

const serviceAccount = require('../firestore.creds.json');

admin.initializeApp({
  credential: admin.credential.cert(serviceAccount),
  databaseURL: `https://${serviceAccount.project_id}.firebaseio.com`,
});

const firestore = admin.firestore();
fireorm.initialize(firestore);
  1. Create your firestore models!
import { Collection } from 'fireorm';

@Collection()
class Todo {
  id: string;
  text: string;
  done: Boolean;
}
  1. Do cool stuff with fireorm!
import { Collection, getRepository } from 'fireorm';

@Collection()
class Todo {
  id: string;
  text: string;
  done: Boolean;
}

const todoRepository = getRepository(Todo);

const todo = new Todo();
todo.text = "Check fireorm's Github Repository";
todo.done = false;

const todoDocument = await todoRepository.create(todo); // Create todo
const mySuperTodoDocument = await todoRepository.findById(todoDocument.id); // Read todo
await todoRepository.update(mySuperTodoDocument); // Update todo
await todoRepository.delete(mySuperTodoDocument.id); // Delete todo

Firebase Complex Data Types

Firestore has support for complex data types such as GeoPoint and Reference. Full handling of complex data types is being handled in this issue. Temporarily, Fireorm will export Class Transformer's @Type decorator. It receives a lamda where you have to return the type you want to cast to. See GeoPoint Example.

Limitations

If you want to cast GeoPoints to your custom class, it must have latitude: number and longitude: number as public class fields. Hopefully this won't be a limitation in v1.

Development

Initial Setup

  1. Clone the project from github:
git clone git@github.com:wovalle/fireorm.git
  1. Install the dependencies.
yarn # npm install

Testing

Fireorm has two types of tests:

  • Unit tests: yarn test # or npm test
  • Integration tests: yarn test:integration # or npm test:integration

To be able to run the integration tests you'll need to create a firebase service account and declare some environment variables.

Test files must follow the naming convention *.test.ts and use jest as the test runner.

Committing

This repo uses Conventional Commits as the commit messages convention.

Release a new version

This repo uses Sematic Release to automatically release new versions as soon as they land on master.

Manual Release If, by any reason, a manual release must be done, these are the instructions: - To release a new version to npm, first we have to create a new tag: bash npm version [ major | minor | patch ] -m "Relasing version" git push --follow-tags - Then we can publish the package to npm registry: bash npm publish - To deploy the documentation bash yarn deploy:doc # or npm deploy:doc

Documentation

  • Fireorm uses typedoc to automatically build the API documentation, to generate it:
yarn build:doc # or npm build:doc

Documentation is automatically deployed on each commit to master and is hosted in Github Pages in this link.
