SQL Formatter

SQL Formatter is a JavaScript library for pretty-printing SQL queries, supporting Standard SQL, Couchbase N1QL, IBM DB2, and Oracle PL/SQL dialects. Current stable version is 2.3.2, with maintenance releases over years. Key differentiator: lightweight, no dependencies, supports placeholder replacement (named and indexed). Lacks TypeScript support in v2 but widely used for formatting SQL in Node.js and browser. Alternatives exist (e.g., prettier-plugin-sql) but sql-formatter is simpler and more focused.
