The PostgreSQL Developer Toolkit

Enterprise PostgreSQL migration engine with dependency resolution and atomic deployments.

npm packages that are simultaneously native PostgreSQL extensions. Monorepo workspace management.

PostgreSQL-native migration system with plan files, dependencies, and verification.

Isolated testing environments with per-test transaction rollbacks—ideal for integration tests, complex migrations, and RLS simulation.

Authentication mocking for Graphile-focused test helpers and emulating row-level security contexts.

Session context injection to add session-local context (e.g., SET LOCAL) into queries—ideal for setting role, jwt.claims, and other session settings.

Express-based API server powered by PostGraphile to expose a secure, scalable GraphQL API over your Postgres database.

Visual API explorer with GraphiQL for browsing across all databases and schemas—useful for debugging, documentation, and API prototyping.

Direct S3 streaming for large files with support for metadata injection and content validation.

S3-compatible ETags created by streaming and hashing file uploads in chunks.

ETag computation via Node stream transformer during upload or transfer.

Deterministic UUIDs generated from hashed content, great for deduplication and asset referencing.

Streaming UUID generation based on piped file content—ideal for upload pipelines.

Collision-resistant filenames utility for structured and unique file names for uploads.

Unified command-line interface for the LaunchQL ecosystem—orchestrates migrations, packages, and deployments.

Auto-generated GraphQL mutations and queries dynamically built from introspected schema data.

SQL constructor providing a robust TypeScript-based query builder for dynamic generation of SELECT, INSERT, UPDATE, DELETE, and stored procedure calls—supports advanced SQL features like JOIN, GROUP BY, and schema-qualified queries.

Fluent GraphQL builder for PostGraphile schemas. ⚡ Schema-aware via introspection, 🧩 composable and ergonomic for building deeply nested queries.

Low-level AST tools and transformations for Postgres query structures.

SQL conversion engine that interprets and converts PostgreSQL syntax.

The definitive PostgreSQL deparser for JavaScript and TypeScript, delivering byte-for-byte SQL round-tripping.

Node.js bindings for libpg_query, converting SQL into parse trees.

Protobuf parser for parsing PostgreSQL Protocol Buffers definitions to generate TypeScript interfaces, utility functions, and JSON mappings for enums.

TypeScript enums for PostgreSQL AST for safe and ergonomic parsing logic.

Type definitions for PostgreSQL AST nodes in TypeScript.

AST utilities for constructing and transforming PostgreSQL syntax trees.
