Turbo Upload Service

Welcome to the Turbo Upload Service 👋

Setting up the development environment

System Package Installation

For a compatible development environment, we require the following packages installed on the system:

• nvm
• yarn
• husky
• docker

Running the Upload Service locally

With a compatible system, follow these steps to start the upload service:

• cp .env.sample .env (and update values)
• yarn
• yarn build
• yarn db:up && yarn db:migrate:latest
• yarn start

Developers can alternatively use yarn start:watch to run the app in development mode with hot reloading provided by nodemon

Database

Scripts

• yarn db:up: Starts a local docker PostgreSQL container on port 5432
• yarn db:down: Tears down local docker PostgreSQL container and deletes the db volume
• yarn db:migrate:list - lists all the migrations applied to the database
• yarn db:migrate:up MIGRATION_NAME: Runs a specific migration on a local PostgreSQL database
• yarn db:migrate:latest: Runs migrations on a local PostgreSQL database
• yarn db:migrate:new MIGRATION_NAME: Generates a new migration file
• yarn dotenv -e .env.dev ...: run any of the above commands against a specific environment file

Migrations

Knex is used to create and run migrations. To make a migration follow these steps:

1. Add migration function and logic to schema.ts

2. Run the yarn command to stage the migration, which generates a new migration script in migrations/ directory

   • yarn db:migrate:new MIGRATION_NAME (e.g. yarn db:migrate:new add_id_to_table)

3. Construct the migration queries in src/db/arch/migrator.ts

4. Update the generated migration file to call the proper migration script.

5. Run the migration:

   • yarn db:migration:latest or yarn knex migration:up MIGRATION_NAME.TS

6. Alternatively, run the migration against a specific environment file:

   • yarn dotenv -e .env.dev yarn db:migrate:latest

Rollbacks

You can rollback knex migrations using the following command:

• yarn db:migrate:rollback - rolls back the most recent migration
• yarn db:migrate:rollback --all - rolls back all migrations
• yarn db:migrate:down MIGRATION_NAME - rolls back a specific migration

Additional knex documentation can be found here.

Docker

Building Image

To build the container:

docker build --build-arg NODE_VERSION=$(cat .nvmrc |cut -c2-8) --build-arg NODE_VERSION_SHORT=$(cat .nvmrc |cut -c2-3) .

Docker Compose

Runs this service, against the most recent version of payment-service and arlocal, and local postgres instances.

docker compose up -d

Run just the upload service against migrated local postgres instance.

docker compose up upload-service --build

Tests

Unit and integration tests can be run locally or via docker. For either, you can set environment variables for the service via a .env file:

• yarn test:local - runs unit and integration tests locally against postgres and arlocal docker containers

Unit Tests

• yarn test:unit - runs unit tests locally

Integration Tests

• yarn test:integration:local - runs the integration tests locally against postgres and arlocal docker containers
• yarn test:integration:local -g "Router" - runs targeted integration tests against postgres and arlocal docker containers
  • watch -n 30 'yarn test:integration:local -g "Router' - runs targeted integration tests on an interval (helpful when actively writing tests)
• yarn test:docker - runs integration tests (and unit tests) in an isolated docker container
