pg-formatter-ts is a TypeScript library that wraps the pgFormatter CLI tool for formatting PostgreSQL SQL code.
With a simple and easy-to-use API, it provides the ability to format SQL code programmatically with various formatting options.

Compared to the existing pg-formatter library, pg-formatter-ts offers improved TypeScript support and better integration with modern TypeScript/JavaScript projects. This library utilizes the same underlying CLI tool, but provides a more streamlined and developer-friendly API. Additionally, pg-formatter-ts supports all available CLI options of pgFormatter, allowing for greater customization and control over the formatting process.

yarn install pg-formatter-ts

Ensure that perl is installed on your system, as pgFormatter relies on it. You can check if Perl is installed by running perl -v in your command line. If it's not installed, please visit the Perl official website for installation instructions.

import { format, PgFormatOptions } from "pg-formatter-ts";

const sqlCode = "SELECT id, name, age FROM users WHERE age >= 18;";
const options: PgFormatOptions = {
    keywordCase: 2,
    spaces: 2,
};

format(sqlCode, options).then((formattedCode) => {
    console.log(formattedCode);
});

pg-formatter-ts accepts an optional PgFormatOptions object as a parameter for the format function. The options available are:

interface PgFormatOptions {
    anonymize?: boolean;
    commaStart?: boolean;
    commaBreak?: boolean;
    config?: string;
    wrapComment?: boolean;
    debug?: boolean;
    commaEnd?: boolean;
    functionCase?: number;
    format?: string;
    nogrouping?: boolean;
    help?: boolean;
    inplace?: boolean;
    keepNewline?: boolean;
    noExtraLine?: boolean;
    maxlength?: number;
    multiline?: boolean;
    nocomment?: boolean;
    numbering?: boolean;
    output?: string;
    placeholder?: string;
    redshift?: boolean;
    spaces?: number;
    separator?: string;
    formatType?: boolean;
    tabs?: boolean;
    keywordCase?: number;
    typeCase?: number;
    version?: boolean;
    wrapLimit?: number;
    wrapAfter?: number;
    noRcfile?: boolean;
    extraFunction?: string;
    extraKeyword?: string;
    noSpaceFunction?: boolean;
}
