The record

Purpose: SQL Formatter is a JavaScript library for pretty-printing SQL queries.
Dialects: It supports BigQuery, ClickHouse, DB2, DuckDB, Hive, MariaDB, MySQL, TiDB, Couchbase N1QL, Oracle PL/SQL, PostgreSQL, Redshift, SingleStoreDB, Snowflake, Spark, SQL Server Transact-SQL, and Trino/Presto.
Formatting options: Options include indentation, keyword and data type case, function and identifier case, logical operator placement, expression width, spacing between queries, and operator spacing.
Placeholder replacement: The library can replace placeholders in prepared SQL statements using supplied parameter values.
CLI: The command line tool accepts SQL from standard input or a file and can write formatted output or update a file in place.
Editor integrations: The project lists VS Code and Vim extensions, a Prettier plugin, and an ESLint plugin integration.
Configuration schema: The project provides a JSON Schema for configuration-file autocompletion and IntelliSense in editors, with usage guides for VS Code and Zed.
License: The software is released under the MIT license.
Limits: It does not support stored procedures or changing the delimiter from a semicolon.
Templating: Templating syntax is not directly supported; the README describes a parameter-type workaround that may not cover every templating construct.
Maintenance: The maintainer says the formatter is in maintenance mode, with feasible bug fixes and likely no new features.
Browser demo: The official demo page exposes controls for language, indentation, case, operator newlines, expression width, and query spacing.
