[Discussion] How painful is migrating legacy React Class Components to Hooks? Are there good tools for this?

Hi all,

I'm a developer exploring a potential tool idea and wanted to get your honest take.

**The problem:** I've heard from several developers that migrating old React Class

Component codebases to Hooks is tedious and error-prone. Converting lifecycles

(componentDidMount → useEffect), refactoring state logic, handling HOCs... it's all

manual work that eats up days.

**My questions:**

  1. Do you have legacy Class Component code that needs converting? How much of your

    codebase is still Class-based?

  2. How painful has the migration been? Is it mostly manual refactoring, or have you

    found tools that help?

  3. Do you know of any existing solutions (open-source or paid) that auto-convert Class

    to Hooks? How well do they work?

  4. If there was a tool that could automatically convert your Class components to Hooks

    with ~90% accuracy (so you just need to review and tweak), would you use it?

    Would you pay for it?

I'm genuinely curious about the scale of this problem and whether it's worth solving.

Thanks for any insights!

P.S. - Not trying to sell anything here, just validating an idea before investing time.
