Package Exports

@travetto/model-firestore
@travetto/model-firestore/__index__.ts

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@travetto/model-firestore) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Firestore Model Support

Firestore backing for the travetto model module.

Install: @travetto/model-firestore

npm install @travetto/model-firestore

# or

yarn add @travetto/model-firestore

This module provides an Firestore-based implementation of the Data Modeling Support. This source allows the Data Modeling Support module to read, write and query against Firestore.

Supported features:

CRUD
Indexed Out of the box, by installing the module, everything should be wired up by default.If you need to customize any aspect of the source or config, you can override and register it with the Dependency Injection module.

Code: Wiring up a custom Model Source

import { InjectableFactory } from '@travetto/di';
import { FirestoreModelConfig, FirestoreModelService } from '@travetto/model-firestore';

export class Init {
  @InjectableFactory({
    primary: true
  })
  static getModelSource(conf: FirestoreModelConfig) {
    return new FirestoreModelService(conf);
  }
}

where the FirestoreModelConfig is defined by:

Code: Structure of FirestoreModelConfig

import { FileResourceProvider } from '@travetto/base';
import { Config } from '@travetto/config';

@Config('model.firestore')
export class FirestoreModelConfig {

  databaseURL?: string;
  credentialsFile?: string;
  emulator?: string;
  projectId: string;
  namespace?: string;
  autoCreate?: boolean;
  credentials?: {
    client_email: string;
    project_id: string;
    private_key: string;
  };

  async postConstruct(): Promise<void> {
    if (this.emulator) {
      process.env.FIRESTORE_EMULATOR_HOST = this.emulator;
    }
    if (this.credentialsFile && !this.credentials) {
      const resources = new FileResourceProvider({ includeCommon: true });
      this.credentials = JSON.parse(await resources.read(this.credentialsFile));
    }
  }
}

Additionally, you can see that the class is registered with the @Config annotation, and so these values can be overridden using the standard Configuration resolution paths.
