ts-morph

I don't see anything wrong that would disqualify your plan. But if the alternative is regex, and you're writing already in TypeScript, you may take a look at ts-morph [0]. TS has very good compiler APIs and that gets you something much safer than text-based replacement while still staying relatively small for a constrained subset. ts-morph wraps those APIs cleanly. Btw, JS doesn't even have an official bytecode. The spec is defined at the language semantics level, so each engine/toolchain invents its own internal representation.

Not really - https://github.com/Microsoft/TypeScript/issues/16607. ts-morph provides an easy way to use the TypeScript Compiler API to view and edit the AST before compile. Once you get your head around the API, which has good examples but isn't thoroughly documented on the web. https://github.com/dsherret/ts-morph

Hi HN, I built a tool [1] that resolves breaking changes when you upgrade npm packages. I know keeping my dependencies updated is good hygiene but I really have no motivations to do them. The time to fix breaking changes then validate them makes the ROI lopsided. Automating these helps me reduce the barrier to a good habit. It works on typescript and tsx projects. BYOK (bring your own GPT-4 key) for the codegen. MIT license. How does it work? - Bumps the package version, builds your project, and then runs tsc over your project to understand what breaks - Uses ts-morph [2] to create an AST of your code to understand the relationships between code blocks - Uses the AST to get type definitions for external methods to understand how to use the new package - Creates a DAG to execute coding tasks in the correct order to handle propagating chang

I've been using ts-morph for this recently, the accompanying AST viewer makes getting started easy. https://github.com/dsherret/ts-morph https://ts-ast-viewer.com

We used tsoa where i work but had issues with complex types [0] so one of our dev rewrote a simpler implementation [1] that use ts-morph [2] under the hood. Not exactly related but we had issues with the official openapi generated so he also wrote a package to codegen typescript client from an openapi file [3] [0]: https://github.com/lukeautry/tsoa/pulls?q=is%3Apr+sort%3Aupd...
