What is CodeQue?

CodeQue is semantic code search engine that understands the code syntax.

It matches code structurally which makes it excellent for more complex queries.

Query language offers wildcards, partial matching and ignores code formatting.

Structural code search is available for JavaScript, TypesScript, HTML, CSS, Python, Lua and more soon.

Text code search with handy wildcards is available for every language and covers common regex search use cases.

ESLint integration 💅

Using CodeQue ESLint plugin you can create your own custom linting rules in zero time.

Custom ESLint rules can help execute on long-term refactors or prevent introducing codebase specific bugs or bad patterns.

Rules can replace your decision log and help standardizing coding conventions across the project or organization.

CodeQue ESLint integration is a no-brainier for any team willing to improve their codebase quality.
