PostgREST Starter Kit

Base project and tooling for authoring REST API backends with PostgREST.

PostgREST Starter Kit


PostgREST enables a different way of building data driven API backends. It does "one thing well" and that is to provide you with a REST api over your database, however to build a complex production system that does things like talk to 3rd party systems, sends emails, implements real time updates for browsers, write integration tests, implement authentication, you need additional components. For this reason, some developers either submit feature requests that are not the scope of PostgREST or think of it just as a prototyping utility and not a powerful/flexible production component with excellent performance. This repository aims to be a starting point for all PostgREST based projects and bring all components together under a well defined structure. We also provide tooling that will aid you with iterating on your project and tools/scripts to enable a build pipeline to push everything to production. There are quite a few components in the stack but you can safely comment out pg_amqp_bridge/rabbitmq (or even openresty) instances in docker-compose.yml if you don't need the features/functionality they provide.


✓ Cross-platform development on macOS, Windows or Linux inside Docker
PostgreSQL database schema boilerplate with authentication and authorization flow
OpenResty configuration files for the reverse proxy
RabbitMQ integration through pg-amqp-bridge
Lua functions to hook into each stage of the HTTP request and add custom logic (integrate 3rd party systems)
✓ Debugging and live code reloading (sql/configs/lua) functionality using subzero-cli
✓ Full migration management (migration files are automatically created) through subzero-cli/sqitch/apgdiff
✓ SQL unit test using pgTAP
✓ Integration tests with SuperTest / Mocha
✓ Docker files for building production images
✓ Community support on Slack
✓ Compatible with subZero Starter Kit if you need a GraphQL API and a few more features with no additional work

Create a New Project

subzero-cli provides you with a base-project command that lets you create a new project structure:

subzero base-project

? Enter the directory path where you want to create the project .
? Choose the starter kit (Use arrow keys)
  subzero-starter-kit (REST & GraphQL) 
❯ postgrest-starter-kit (REST) 

After the files have been created, you can bring up your application (API). In the root folder of application, run the docker-compose command

docker-compose up -d

The API server will become available at the following endpoint:

Try a simple request

curl http://localhost:8080/rest/todos?select=id,todo

Development workflow and debugging

Execute subzero dashboard in the root of your project.
After this step you can view the logs of all the stack components (SQL queries will also be logged) and if you edit a sql/conf/lua file in your project, the changes will immediately be applied.


The starter kit comes with a testing infrastructure setup. You can write pgTAP tests that run directly in your database, useful for testing the logic that resides in your database (user privileges, Row Level Security, stored procedures). Integration tests are written in JavaScript.

Here is how you run them

npm install                     # Install test dependencies
npm test                        # Run all tests (db, rest)
npm run test_db                 # Run pgTAP tests
npm run test_rest               # Run integration tests



Anyone and everyone is welcome to contribute.
