Bloom Backend Services

This package is a NestJS application that provides a core set of backend services via REST API endpoints to apps using the Bloom Housing framework. Information is stored in a Postgres database, accessed via TypeORM.

OpenAPI Documentation

OpenAPI (fka Swagger) documentation is automatically generated by the server at http://localhost:3100/docs/ for a standard local development environment. A raw JSON version of the schema is also available at /docs-json/, suitable for API client code generation or other code-based consumers.

Getting Started

Install Node.js 14.x brew install node@14.
Install Postgres 12 brew install postgresql
Copy the .env.template within backend/core to .env and edit variables appropriate to your local environment. Ensure sure the Database URL and Test Database URL match your Postgres configuration.
Install dependencies yarn install within backend/core

Seeding the Database

There are two databases used in this project: bloom and bloom_test. The first is used every time you are starting a project with yarn dev and second one is only used in end-to-end tests. Corresponding TypeORM configs are defined in ormconfig.ts and ormconfig.test.ts. If you are just starting to work with the projects it's best to simply run:

yarn && yarn db:reseed

which will create the bloom DB for you, migrate it to the latest schema, and seed with appropriate dev data. If running the reseed command requires that you input a password for Postgres, set the following environment variables: PGUSER to postgres and PGPASSWORD to the default password you inputted for the postgres user during Postgres installation. If you get the FATAL: database "<user>" does not exist error please run: createdb <user> first.

Dropping the DB:

yarn db:drop

Creating the DB:

yarn db:create

Seeding the DB:

yarn db:seed

Generating a new migration:

yarn db:migration:generate

Applying migrations:

yarn db:migration:run

Running Tests

End-to-end tests:

yarn test:e2e:local

Unit tests:

yarn test

Translations

The backend keeps translations for email related content in the DB in the translations table. The /translations endpoint exposes CRUD operations on this table (admin only). Translations are defined for each county code and language pair e.g. (Alameda, en). To modify a particular translation pair:

Fetch GET /translations and list all the translations
Find an ID of a pair that interest you
Use PUT /translations/:translationId to modify it's content
