Object document mapper for Angular Firestore by Google's Firebase

Saving, reading and updating on Google Firebase with AngularFirestore is a tedious and repetitive task. This project aims to minimize this problem.

At the time, insert, read, list all, delete, delete all and count are working. TODO: working to save relationships recursively and to update an entity.

Installation

1. Clone the repository to your project as a submodule: git add submodule https://github.com/lsoaresesilva/firebase-odm.git

Usage

1. Configure AngularFirebase in your project: https://github.com/angular/angularfire2
2. Run npm test, and verify if everything works as expected (it will run the unit tests and create some documents in your firestore)
3. Create a simple class and extend from Document (we may call it a Model from MVC)
4. Inside a component, inject AngularFireStore as usual
5. Pass this injected instance to the constructor of your class which extended from Document
6. Enjoy!

Example

\\file: person.ts

@Collection("personCollection")
export class Person extends Document{
  name:string;
}

\\file: your-component.ts

export class AppComponent {
  
  constructor(public db: AngularFirestore){
    let person = new Person(this.db);
    person.name = "Leonardo"
    person.add().subscribe(result=>{
      console.log(result.id) // optional
    });
    

    Person.get(this.db, 'your-entity-id').subscribe(
      document=>{ // its a person!},
      err=>{// ops, an error, maybe a document with this id does not exists.});
    Person.getAll(this.db).subscribe(result=>{ // list of persons}); //
    Person.count(this.db).subscribe(result=>{ // number of documents});

    person.delete();
    Person.deleteAll(this.db);
  }
}

\\file: animal.ts

@Collection("animalsCollection")
export class Animal extends Document{
  name:string;
}

\\file: person.ts
@Collection("peopleCollection")
export class Person extends Document{
  name:string;
  @oneToMany({document:Animal})
  animal
}


\\file: your-component.ts

export class AppComponent {
  
  constructor(public db: AngularFirestore){
    let animal = new Animal(thid.db)
    animal.name = "Scooby doo";
    let person = new Person(this.db);
    person.name = "Leonardo"
    person.animal = animal
    person.add().subscribe(result=>{
         // Will also save animal :)
    });
   
  }
}
