js2flowchart is a JavaScript library that converts JavaScript code into SVG flowcharts by parsing the code's AST. It works on both client and server, supports ES6, and offers abstraction levels, custom modifiers, and highlighting to help learn, explain, and document code.

Use cases

• generate an SVG flowchart from JavaScript code
• visualize code logic to understand someone else's code
• create diagrams for code documentation
• explain code step by step at different abstraction levels
• render flowcharts of functions in a browser or on a server
• highlight or blur parts of a code flowchart

When to choose

• you need automatic flowchart generation from JavaScript source code
• you want to teach or document code logic visually
• you need customizable SVG output with abstraction levels and modifiers

When to avoid

• you need flowcharts for languages other than JavaScript
• you need multi-file codebase visualization (consider Codecrumbs instead)
• you need actively developed features or long-term support
