node-service-template provides a "battery-included" starter template for building enterprise Node.js webservices.

It comes with the following out-of-the-box:

  • fastify as a basis for the general web application skeleton;
  • Modular, domain-driven structure that encourages separation of concerns;
  • Server/app separation, for convenient bootstrapping in e2e tests;
  • Global error handler;
  • JSON-based, single line standardized logging;
  • Automatic population of for incoming requests based on x-request-id header, or generation of new UUID if none is set, for the purposes of distributed tracing.



Basic building block examples:



  • Generate OpenAPI specification from your route definitions;
  • Validate your OpenAPI specification.
  • GenerateJwt generate jwt for dev usage.

Service template also comes with a curated set of plugins installed:

  • @fastify/helmet (security headers)
  • @fastify/swagger (OpenAPI specification generation)
  • @fastify/swagger-ui (visualizing OpenAPI specification)
  • @fastify/awilix (dependency injection)
  • @fastify/schedule (scheduling background jobs)
  • @fastify/auth (authentication)
  • fastify-graceful-shutdown (handling SEGTERM gracefully)
  • fastify-no-icon (avoiding warnings when sending GET calls via browser)
  • fastify-custom-healthcheck (registering app and dependency healthchecks)
  • @lokalise/fastify-extras -> metricsPlugin (exposing Prometheus metrics)
  • @lokalise/fastify-extras -> requestContextProviderPlugin (storing requestId in AsyncLocalStorage and populating requestContext on request)
  • @lokalise/fastify-extras -> newRelicTransactionManagerPlugin (creating custom NewRelic spans for background jobs)
  • @lokalise/fastify-extras -> bugsnagPlugin (reporting errors to BugSnag)
  • @lokalise/fastify-extras -> prismaOtelTracingPlugin (generating OpenTelemetry metrics for DB operations using prisma)

Note that some of the fastify-extras plugins may not be relevant for you (e. g. if you are not using Prometheus, New Relic or Bugsnag). In that case you should remove the plugins and delete everything that breaks when you attempt to build the project.

We recommend you to create your own @your-org/fastify-extras package and create your own mix of vendor plugins that are relevant for the technological stack of your organization, and replace @lokalise/fastify-extras with it.

Getting Started

  1. Install all project dependencies:
npm install
  1. Copy the .env.default file to a new .env file. You can do this with the following npm script:
npm run copy:config
  1. Run migrations to synchronize your database schema with defined models.
npm run db:migration:dev
  1. Generate Prisma client for type-safe DB operations:
npm run db:update-client
  1. You can use Docker Compose for launching all the infrastructural dependencies locally:
docker compose up -d
  1. To run application:
npm run start:dev

OpenAPI specification

You can access OpenAPI specification of your application, while it is running, by opening SwaggerUI

Create jwt for dev usage

By default, all calls to the node-template app will require a valid JWT token.

You have multiple options to ease your development:

  1. Comment onRequest hook for JWT verification here
  2. Generate a valid JWT with provided generateJwt script

Generate JWT script

  • Script requires public-private key pair encrypted with RS256 algorithm. Run it in keys directory.
ssh-keygen -t rsa -b 4096 -m PEM -f jwtRS256.key
# Don't add passphrase
openssl rsa -in jwtRS256.key -pubout -outform PEM -out

or if you are in node-service-template dir

ssh-keygen -t rsa -b 4096 -m PEM -f ./scripts/keys/jwtRS256.key
# Don't add passphrase
openssl rsa -in ./scripts/keys/jwtRS256.key -pubout -outform PEM -out ./scripts/keys/
  • Default file names are jwtRS256.key for private key and for public key
  • Run JWT generate script
npm run jwt:generate
  • Copy your public key to .env file as a one line string, it will be printed with a token in console to make things easier. Example output:
Public key:
