What is codemirror-lang-n8n-sql?

This repository provides a code editor plugin that adds support for writing SQL queries with n8n expressions mixed in. It's built on CodeMirror 6, which is a popular JavaScript library that powers code editors in web applications. If you're using n8n, a workflow automation tool, you may need to write SQL queries as part of your automation. This plugin lets you write those queries in a code editor that understands both standard SQL syntax and n8n's special expression language, so it can highlight keywords correctly, offer helpful suggestions, and catch errors as you type. The plugin was created by extending CodeMirror's existing SQL language support to recognize n8n-specific syntax alongside regular SQL. This means when you're building a workflow that queries a database, the editor helps you write cleaner, more reliable code by understanding both languages at once instead of just treating everything as plain text. Important note: this repository is now archived and read-only. The actual, maintained version has been moved into n8n's main codebase as part of their larger monorepo. If you're looking to use or contribute to this project, you'll want to find it in the main n8n repository instead of this standalone version.
