@pgsql/enums is a TypeScript library providing enum definitions for PostgreSQL AST nodes, primarily used in conjunction with pgsql-parser. It offers a comprehensive and type-safe way to work with PostgreSQL enum values in query parsing and AST manipulation.

Install the package via npm:

npm install @pgsql/enums

Here's a simple example showing how to work with enums, converting between enum names and their numeric values:

import { ObjectType } from '@pgsql/enums';

// Get the numeric value of an enum
const tableValue = ObjectType.OBJECT_TABLE;
console.log(tableValue); // 41

// Convert from value back to enum name
const enumName = ObjectType[41];
console.log(enumName); // "OBJECT_TABLE"

// Use in comparisons
if (someNode.objectType === ObjectType.OBJECT_TABLE) {
  console.log("This is a table object");
}

Our latest is built with PostgreSQL 17 enum definitions.

• pgsql-parser: The real PostgreSQL parser for Node.js, providing symmetric parsing and deparsing of SQL statements with actual PostgreSQL parser integration.
• pgsql-deparser: A streamlined tool designed for converting PostgreSQL ASTs back into SQL queries, focusing solely on deparser functionality to complement pgsql-parser.
• @pgsql/parser: Multi-version PostgreSQL parser with dynamic version selection at runtime, supporting PostgreSQL 15, 16, and 17 in a single package.
• @pgsql/types: Offers TypeScript type definitions for PostgreSQL AST nodes, facilitating type-safe construction, analysis, and manipulation of ASTs.
• @pgsql/enums: Provides TypeScript enum definitions for PostgreSQL constants, enabling type-safe usage of PostgreSQL enums and constants in your applications.
• @pgsql/utils: A comprehensive utility library for PostgreSQL, offering type-safe AST node creation and enum value conversions, simplifying the construction and manipulation of PostgreSQL ASTs.
• pg-proto-parser: A TypeScript tool that parses PostgreSQL Protocol Buffers definitions to generate TypeScript interfaces, utility functions, and JSON mappings for enums.
• libpg-query: The real PostgreSQL parser exposed for Node.js, used primarily in pgsql-parser for parsing and deparsing SQL queries.
