Which library to use for AST manipulation?

• abracadabra

  5 730 9.0 TypeScript

  Automated refactorings for VS Code (JS & TS) ✨ It's magic ✨

I'm the author of Abracadabra, a VS Code extension that brings extra automated refactorings for JS & TS code.

• recast

  6 4,821 6.1 TypeScript

  JavaScript syntax tree transformer, nondestructive pretty-printer, and automatic source map generator

I had great results with a combination of babel + recast. Babel is doing the job and Recast is mostly here to preserve the original style when printing code again. I animated a workshop @ Node.JS Montréal 2019 that was recorded here. We cover the parse/transform/print of code using Babel (live coding starts around 45').

• SurveyJS

  Open-Source JSON Form Builder to Create Dynamic Forms Right in Your App. With SurveyJS form UI libraries, you can build and style forms in a fully-integrated drag & drop form builder, render them in your JS app, and store form submission data in any backend, inc. PHP, ASP.NET Core, and Node.js.

  

• TypeScript

  1,305 97,944 9.9 TypeScript

  TypeScript is a superset of JavaScript that compiles to clean JavaScript output.

  

I think a great alternative in your case would be to use the typescript compiler itself.
