Fast TypeScript Analyzer

FTA (Fast TypeScript Analyzer) is a super-fast TypeScript static analysis tool written in Rust. It captures static information about TypeScript code and generates easy-to-understand analytics that tell you about complexity and maintainability issues that you may want to address.

FTA uses swc to parse your code then runs various analytical routines against it to understand how complex and maintainable it is likely to be.

Features

For conveinience, FTA generates a single FTA Score that serves as a general, overall indication of the quality of a particular TypeScript file.

That said, all metrics are exposed and it is up to users to decide how it's metrics can enhance productivity for your team.

Under the hood, various metrics are calculated:

• The Halstead Metrics: uses the unique and total number of operators and operands in the code to calculate several complexity measures such as size, vocabulary, difficulty, time to program and "delivered bugs".
• Cyclomatic Complexity: the effective number of distinct logical paths through the code
• More likely to follow
