Node.js API Starter Kit

Node.js API Starter Kit is a project template for building Node.js backend applications optimized for serverless infrastructure such as Google Cloud Functions, AWS Lambda, Azure Functions, etc. Use it as an API server for your front-end app.

Features

Database first design; auto-generated strongly typed data models (TypeScript)
Authentication and authorization using OAuth 2.0 providers (Google, Facebook, GitHub, etc.)
Stateless sessions implemented with JWT tokens and a session cookie (compatible with SSR)
GraphQL API example, implemented using the code-first development approach
Database schema migration, seeds, and REPL shell tooling
Transactional emails using Handlebars templates and instant email previews
Structured logs and error reporting to Google StackDriver
Pre-configured unit testing tooling powered by Jest and Supertest
Application bundling with Rollup as an optimization technique for serverless deployments
Rebuilds and restarts the app on changes when running locally
Pre-configured for local, dev, test, and prod environments
The ongoing design and development is supported by these wonderful companies:

Requirements

Node.js v14, Yarn package manager

VS Code editor with recommended extensions

Getting Started

Clone the repo — git clone -o seed https://github.com/kriasoft/node-starter-kit.git.
Update environment variables for local, dev, test, and prod environments (./env).
Install project dependencies — yarn install
Bootstrap PostgreSQL database — yarn db:create
Finally, launch the app — yarn start, it will become available at http://localhost:8080.

Use APP_ENV environment variable to execute scripts for different environments, for example:

$ APP_ENV=test yarn db:migrate
$ APP_ENV=test yarn start

IMPORTANT: Ensure that VSCode is using the workspace versions of TypeScript and ESLint.

Scripts

yarn start — Launches the app in development mode on http://localhost:8080
yarn build — Compiles and bundles the app for deployment
yarn lint — Validate code using ESLint
yarn tsc — Validate code using TypeScript compiler
yarn test — Run unit tests with Jest, Supertest
yarn repl — Connect to the database using Knex REPL shell
yarn psql — Connect to the database using PostgreSQL CLI
yarn db:create — Create a new database
yarn db:version — Check the current version of the database
yarn db:migrate — Migrate database schema to the latest version
yarn db:rollback — Rollback the latest migration
yarn db:seed — Seed database with sample / reference data
yarn db:reset — Re-apply the latest DB schema migration file
yarn update-types — Generate strongly typed data models from database schema

Optionally set APP_ENV to local (default), dev, test, or prod before running these scripts.

How to Configure 0Auth 2.0 Login Flow

For each 3rd party identity provider that needs to be enabled for your app, you will need to obtain application credentials, often called client ID/secret.

Google

Go to Google Cloud Console
Create a new GCP project
Configure OAuth concent screen
Create OAuth 2.0 client with http://localhost/auth/google/return as the callback URL
Update GOOGLE_CLIENT_ID, GOOGLE_CLIENT_SECRET environment variables found in ./env/.env.* for each environment that you need.

From there on, visiting http://localhost:8080/auth/google (or, opening it in a popup window) would initiate login flow via Google.

Facebook

Go to Facebook Developer website
Create a new Facebook App, enable Facebook Login for this app
Close Quickstart dialog and go straight to the app settings
Add http://localhost/auth/facebook/return as the callback URL for the login flow
Copy and paste the newly created Facebook App ID and secret to FACEBOOK_APP_ID, FACEBOOK_APP_SECRET variables found in env/.env.* files for each environment that you need.

From there on, visiting http://localhost:8080/auth/facebook (or, opening it in a popup window) would initiate login flow via Facebook.

How to Deploy

The deployment script (yarn deploy) relies on Google Cloud CLI (gcloud) tool that you can download from here. For CI/CD workflows you may need a Docker image like this one.

gcloud auth login — Authorize Google Cloud SDK (CLI) tool to use your Google account.

Create a new GCP project for your app with IDs such as example for production, and example-test for test / QA environments. Ensure that Cloud Build API and Cloud Functions API are enabled in your GCP project's settings here.

Create a Cloud SQL database instance here in the same region where your app needs to be deployed. Using a micro instance of Cloud SQL with 0.6 GB RAM should be OK for testing and low traffic websites.

Ensure that GOOGLE_CLOUD_PROJECT, GOOGLE_CLOUD_REGION, PGDATABASE, PGUSER and the other environment variables are correctly set for the target deployment environment (e.g. /env/.env + /env/.env.prod for production).

Finally, compile and deploy the app by running:

yarn build — Compiles the app into the .build folder
APP_ENV=<env> yarn db:migrate — Migrates database (schema) to the latest version
APP_ENV=<env> yarn deploy — Deploys the app to Google Cloud Functions (GCF)

Where <env> is the target environment, e.g. APP_ENV=prod yarn deploy.

How to Update

yarn set version latest — Bump Yarn to the latest version
yarn upgrade-interactive — Update Node.js modules (dependencies)
yarn pnpify --sdk vscode — Update TypeScript, ESLint, and Prettier settings in VSCode
