@stackline/pg-types

Dependency-free PostgreSQL type parsers compatible with pg-types 2.2.0.

Documentation | npm | Issues | Repository

Current package version: 1.0.3

Why this package?

Dependency-free PostgreSQL result parsers with the public CommonJS and TypeScript contract of pg-types@2.2.0. This independent, maintained fork is the compatibility leaf used by @stackline/pg.

Compatibility

Item	Value
Package	`@stackline/pg-types@1.0.3`
Node.js runtime	`>=4`
CommonJS / primary entry	`./index.js`
ES module entry	`./index.mjs`
Type declarations	`./index.d.ts`

getTypeParser(oid, format?)
setTypeParser(oid, parser)
setTypeParser(oid, format, parser)
arrayParser.create(source, transform?)
builtins
TypeId as the runtime value promised by the historical declarations
CommonJS, Node.js 4 or newer and TypeScript 3.9 declarations
historical pg-types package name through npm aliasing

Valid PostgreSQL values retain the 2.2.0 parser behavior. Dangerous parser map keys are isolated, and malformed timestamp processing is bounded instead of retrying a regular expression at every input position.

See COMPATIBILITY.md and MIGRATION.md for the complete contract.

Installation

Install

Direct scoped use:

npm install @stackline/pg-types

Drop-in replacement without changing existing imports:

Usage

npm install pg-types@npm:@stackline/pg-types

var types = require('pg-types')

types.setTypeParser(types.builtins.INT8, function (value) {
  return parseInt(value, 10)
})

The scoped form exposes the same API:

var types = require('@stackline/pg-types')
var parseTimestamp = types.getTypeParser(types.builtins.TIMESTAMPTZ)

console.log(parseTimestamp('2026-08-30 12:00:00+00'))

Security

Report vulnerabilities through GitHub private vulnerability reporting. Do not disclose an unpatched vulnerability in a public issue. See SECURITY.md.

Local Development

git clone https://github.com/alexandroit/stackline-pg-types.git
cd stackline-pg-types
npm ci
npm run verify

Release tooling uses Node.js 24.20.0 and npm 11.19.0. The consumer runtime contract remains the one documented above.

Consumer Smoke Test

Run the repository's existing consumer/package check after installing development dependencies:

npm run test:smoke

Release Checklist

Dependency Standard

The published package has zero runtime dependencies. Exact source from the five historical parser dependencies is maintained in-tree so an abandoned transitive package cannot re-enter the install graph. Every release verifies a warning-free packed install, npm ls --all, production and full audits, license inventory, package metadata and runtime/type matrices.

The source inventory and license notices are documented in DEPENDENCY_REVIEW.md and THIRD_PARTY_LICENSES.md.

Run npm run verify and inspect the package contents before release. Publish a new version through the GitHub Actions publishing workflow, using the SHA-512 digest of the reviewed tarball. Verify the exact published version, tarball integrity, and npm provenance after the run.
