PGStar

A server for building transactional HTTP APIs with Postgres and Starlark.

About PGStar

PGStar is a simple toolkit that can enable HTTP API development.

As a primary goal PGStar is intended to abstract your application away from Postgres operations. As a configuration, Starlark seemed like a great language choice. The language is easily embeddable with starlark-go, provides no hidden means of IO, and was indended to be a configuration language.

The workflow for PGStar is simple.

• Create a starlark script to do something.
• Update config.star with a route to the new script.

The safeties guaranteed are as follows.

• All database interactions happen in a transaction.
• All failures result in transaction rollback.
• Your data stays consistent.

Getting Started

Instructions can be found in the docs/ directory.

• Installation
• Hello World Example
• Module Details

Design Choices

• Starlark was chosen because it is a configuration language and resembles Python.
• Functions shall panic only when a system issue occurs and pass all other errors back to be handled in a tuple.
• Built-in modules should only support

Development Plan Notes

These are things slated to be added to PGStar.

• Implement package management system (using git repos)
• • Versioning structure
• • Caching mechanisms
• Implement schema management tooling (with plain sql files)
• Implement logging module
• • Default log levels: DEBUG, INFO, ERROR, WARNING, DEPRECATED
• • Custom log level support
• • Override print's default level from INFO
• • Output to STDOUT or log file.
• Identify and implement strategy for test coverage
