Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

Prettier SQL NPM version GitHub Workflow Status (event) Coveralls VSCode

Prettier SQL is a JavaScript library for pretty-printing SQL queries.

It started as a port of a PHP Library, but has since considerably diverged.

Prettier SQL supports the following dialects:

It does not support:

  • Stored procedures.
  • Changing of the delimiter type to something else than ;.

Try the demo.

Install

Get the latest version from NPM:

npm install prettier-sql

Also available with yarn:

yarn add prettier-sql

Documentation

You can read more about how the library works in DOC.md

Usage

Usage as library

import { format } from 'prettier-sql';

console.log(format('SELECT * FROM tbl'));

This will output:

SELECT
  *
FROM
  tbl

You can also pass in configuration options:

format('SELECT * FROM tbl', {
	language: 'spark', // Defaults to "sql" (see the above list of supported dialects)
	indent: '  ', // Defaults to two spaces
	uppercase: false, // Defaults to true
	linesBetweenQueries: 2, // Defaults to 1
});

Placeholders replacement

// Named placeholders
format("SELECT * FROM tbl WHERE foo = @foo", {
  params: {foo: "'bar'"}
}));

// Indexed placeholders
format("SELECT * FROM tbl WHERE foo = ?", {
  params: ["'bar'"]
}));

Both result in:

SELECT
  *
FROM
  tbl
WHERE
  foo = 'bar'

Usage from command line

The CLI tool will be installed under prettier-sql and may be invoked via npx prettier-sql:

prettier-sql -h
usage: sqlfmt.js [-h] [-o OUTPUT] \
[-l {bigquery,db2,hive,mariadb,mysql,n1ql,plsql,postgresql,redshift,spark,sql,tsql}] [-c CONFIG] [--version] [FILE]

Prettier SQL

positional arguments:
  FILE            Input SQL file (defaults to stdin)

optional arguments:
  -h, --help      show this help message and exit
  -o, --output    OUTPUT
                    File to write SQL output (defaults to stdout)
  -l, --language  {bigquery,db2,hive,mariadb,mysql,n1ql,plsql,postgresql,redshift,spark,sql,tsql}
                    SQL dialect (defaults to standard sql)
  -c, --config    CONFIG
                    Path to config json file (will use default configs if unspecified)
  --version       show program's version number and exit

By default, the tool takes queries from stdin and processes them to stdout but one can also name an input file name or use the --output option.

echo 'select * from tbl where id = 3' | prettier-sql
SELECT
  *
FROM
  tbl
WHERE
  id = 3

The tool also accepts a JSON config file with the --config option that takes this form:
All fields are optional and all fields that are not specified will be filled with their default values

{
	"indent": string,
	"uppercase": boolean,
	"keywordPosition": "standard" | "tenSpaceLeft" | "tenSpaceRight",
	"newline": "always" | "lineWidth" | "never" | number,
	"breakBeforeBooleanOperator": boolean,
	"aliasAs": "always" | "select" | "never",
	"tabulateAlias": boolean,
	"commaPosition": "before" | "after" | "tabular",
	"parenOptions": {
		"openParenNewline": boolean,
		"closeParenNewline": boolean
	},
	"lineWidth": number,
	"linesBetweenQueries": number,
	"denseOperators": boolean,
	"semicolonNewline": boolean,
}

Usage without NPM

If you don't use a module bundler, clone the repository, run npm install and grab a file from /dist directory to use inside a <script> tag. This makes Prettier SQL available as a global variable window.prettierSql.

Usage with VSCode

Prettier SQL is also available as a VSCode extension here:
