SQL Template Strings lets Node.js developers write prepared‑SQL statements using ES6 tagged template literals. By interpolating values directly in a template (e.g., `SQL\`SELECT * FROM books WHERE id = ${id}\``) it automatically builds the driver‑specific query text, placeholder string and values array for MySQL, MySQL2, PostgreSQL and Sequelize, while also offering chaining methods (`append`, `setName`, `useBind`) for dynamic query composition. It’s aimed at JavaScript/Node developers who want safer, more readable SQL without manually handling parameter placeholders.
