Astexplorer

AST Explorer is a web-based tool for parsing source code into abstract syntax trees and visualizing the resulting tree structure. It serves as a code inspector and transformation playground, allowing users to explore the structural representation of various programming languages through an interactive browser interface.

The tool provides a transformation environment where users can apply modification rules to parsed trees to test code modification logic. It features bidirectional mapping that highlights matching tree nodes and source text simultaneously as the cursor moves across the editor.

The platform supports importing code via file uploads or drag-and-drop interfaces and allows for the sharing of specific code states and parser configurations through state-encoded URLs.

    This project is a unified toolchain for JavaScript and TypeScript development, providing a suite of specialized tools for bundling, parsing, linting, and formatting source code. The toolchain is implemented in Rust and utilizes a shared internal representation to allow multiple tools to operate on the same parsed source code. It employs a parallelized analysis pipeline and single-pass parsing with error recovery to process files across CPU cores. The suite covers several core capability areas, including static analysis for identifying programmatic errors, automated style standardization, and

    ESTree is a formal schema and set of object interfaces used to represent JavaScript source code as a standardized abstract syntax tree. It serves as a common tree format and parser standard to ensure interoperability between different JavaScript parsers and transformation tools. The specification provides a consistent way to model language constructs, including statements, expressions, and module declarations. It includes detailed representations for modern language features such as classes, private identifiers, and short-circuiting logic like nullish coalescing and optional chaining. The pr

    ts-morph is a TypeScript AST manipulation library and a high-level wrapper for the TypeScript compiler API. It provides a programmatic interface for analyzing, modifying, and generating TypeScript source code, serving as a tool for automated code refactoring and source code generation. The library simplifies the process of navigating and inspecting project structures by offering an object-oriented abstraction over the underlying compiler API. It allows for the programmatic transformation of existing codebases to automate structural updates and bulk code migrations. Its capabilities cover sta

    Babel is a pluggable JavaScript compiler and transpiler that converts modern ECMAScript syntax into backwards-compatible versions of the language. It functions as an abstract syntax tree manipulator, parsing source code into a hierarchical structure to traverse and modify nodes for custom code transformations. The system utilizes a plugin-driven architecture to apply specific transformation rules and supports presets that bundle multiple plugins into named configuration groups. This enables the transformation of experimental syntax and the injection of non-global polyfills to ensure consisten
