Migrate components from JS to TypeScript

Connect your repo and name the components to convert. The agent adds real types, fixes the fallout, verifies the build, and opens a pull request you can review.

The challenge

Why this is usually hard

Converting components to TypeScript is rarely a rename. Props need real types, shared shapes have to be inferred from how things are actually used, and every consumer of a converted file can sprout new type errors. Done piecemeal it stalls; done in one giant manual pass it produces a diff nobody wants to review.

How it works

From prompt to shipped

  1. 1

    Connect your repo

    $ connect repo

    Point the agent at your GitHub repository. It operates on a clone, so your branches are not touched.

  2. 2

    Pick the components

    $ migrate these components to TypeScript

    Name the components or folder to migrate. The agent indexes the code semantically and by symbol to see how each one is used across the project.

  3. 3

    Add real types

    In a sandbox clone it renames files, infers prop and state types from actual usage, and adds shared type definitions — not blanket any.

  4. 4

    Verify the whole build

    verify

    It runs typecheck, tests and build to catch and resolve type errors that ripple into consumers before the change is offered.

  5. 5

    Open a pull request

    $ open pr

    You get a reviewed PR scoped to the migration, with a summary of what was typed. The repo only changes when you merge.

Why code-anything

What you get out of the box

Real types, not any

Props and shared shapes are inferred from how the code is actually used, so you get meaningful types rather than escape hatches.

Ripple effects handled

Symbol-aware indexing tracks every consumer of a converted file, so new type errors downstream get resolved in the same pass.

Build stays green

Typecheck, tests and build all run in the sandbox, so the PR arrives compiling cleanly under TypeScript.

Scoped, reviewable PR

The change comes as a focused pull request limited to the migration, so the diff is something you can actually review.

In practice

What it looks like

A grounded version of the flow: the agent infers real types, fixes the downstream fallout, and verifies the build before opening a PR.

The flow
$ connect repo  acme/web-app
$ migrate these components from JS to TypeScript
✓ indexed usage of 18 components (semantic + symbol)
✓ converted to .tsx, inferred prop and state types
✓ resolved type errors in downstream consumers
✓ typecheck · tests · build all pass
→ opened PR #427  "Migrate components to TypeScript"

What you get

  • Selected components converted to TypeScript with real types
  • Prop and shared types inferred from actual usage, not blanket any
  • Downstream type errors resolved in the same change
  • A scoped pull request that passes typecheck, tests and build

FAQ

Common questions

No. It infers prop, state and shared types from how the code is actually used, aiming for meaningful types. The goal is a migration that adds real safety, not one that silences the compiler.
