@pgsql/enums

@pgsql/enums is a package that provides PostgreSQL AST enums in TypeScript for easier usage and type safety within your projects that interact with PostgreSQL's AST nodes.

Installation

npm install @pgsql/enums

Usage

After installation, you can import the enums directly from the package and use them in your code. This helps in maintaining type safety and ensuring that only valid enum values are used.

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

// Example usage
const exprKind: A_Expr_Kind = A_Expr_Kind.AEXPR_LIKE;

switch(exprKind) {
    case A_Expr_Kind.AEXPR_IN:
    case A_Expr_Kind.AEXPR_BETWEEN:
    case A_Expr_Kind.AEXPR_BETWEEN_SYM:
    // Add other enum cases as needed
        console.log('Enum value is valid');
        break;
    default:
        throw new Error('Unexpected enum value');
}

In this example, A_Expr_Kind is an enum imported from @pgsql/enums, and exprKind is a variable of type A_Expr_Kind. This setup ensures that exprKind can only hold values that are valid members of the A_Expr_Kind enum, providing compile-time type checking and reducing runtime errors.
