E2E Tests GitHub Releases TypeScript

Juno

Bits of Good's central infrastructure API, integrating several in-house services to simplify and streamline project development.

Project Description

Juno is a monorepo using a combination of NestJS, gRPC, Protobuf, Prisma, and Postgres for API endpoints, interservice communication, and object storage/modeling.

Packages are managed through PNPM Workspaces. The current packages are as follows:

  • api-gateway: The publicly visible API routes and their first-layer validation + logic. Decides what services to utilize per-request via Remote Procedure Call (RPC) based on the API route and given information

  • auth-service: An internal service used to handle all API authentication necessities. Provides RPC endpoints for API key generation/validation/revocation and JWT generation/validation. Used in some endpoints but primarily as middleware within the gateway to ensure authorized access to other services

  • db-service: An internal service that interfaces with the database layer (Postgres). Handles all schema structuring and object relations (users, projects, api keys, etc.). This was kept as a single service to provide an interface for all other services to perform CRUD operations on the data they work with without needing to know the underlying storage internals

  • email-service: A SendGrid-based central service for managing per-project mailing functionality with support for all major mailing providers.

  • logging-service: A dedicated logging service for error and audit logs, including traces, metrics information, and sentry.io integration.

Getting Started

Warning

Due to several of the initialization and configuration scripts requiring Unix-specific functionality, building on Windows is currently not supported. However, you can still install Juno onto Windows via WSL2. When later installing Docker Desktop, follow the official instructions to ensure Docker Desktop WSL 2 is enabled.

Prerequisites

Using Docker

As this repository contains multiple packages, Docker is used to spin up all microservices in order with their respective dependencies. For more details regarding the docker process and its internal networking mechanism, take a look at the docker-dev-compose.yml and Dockerfile file.

Most of the docker-related functionality has been abstracted away into pnpm commands.

Installation

All package dependencies must first be installed by using the following command in the root directory:

pnpm install

Development

For spinning up the stack and automatically updating as changes are made to files:

pnpm start:dev:live-all

Making requests

Requests can be made at the endpoint localhost:3000/some/request/path.

Testing

Juno currently has support for E2E tests via Jest.

To run tests a single time for a particular service:

  • api-gateway: pnpm test:e2e:api-gateway
  • auth-service: pnpm test:e2e:auth-service
  • db-service: pnpm test:e2e:db-service

To continuously run tests for a service as file changes are made:

  • api-gateway: pnpm test:e2e:api-gateway-live
  • auth-service: pnpm test:e2e:auth-service-live
  • db-service: pnpm test:e2e:db-service-live

Troubleshooting

Windows

Make sure everything is done through the Windows Subsystem for Linux (WSL).

Some common issues:

  • Forgetting to install protoc
  • Incorrect line endings in .sh files (should be LF, not CRLF)
  • Error message additional property <> is not allowed: Docker Desktop should be updated to v4.24+
  • Error message db-service is unhealthy: Make sure all shell scripts have correct chmod permissions
  • Error message <>.sh: Permission denied: Make sure all shell scripts have correct chmod permissions

If VSCode outputs Failed to connect. Is Docker running?:

  • First, ensure Docker Desktop is actually running.
  • If it is, Docker Desktop most likely decided to nuke your settings, re-enable WSL in Settings > Resources > WLS integration

To add chmod permissions to all shell scripts:

chmod +x packages/db-service/entrypoint.sh
