Henry Q. Dineen ed1351c4fb [compiler] improve zod v3 backwards compat (#34877) ... ## Summary When upgrading to `babel-plugin-react-compiler@1.0.0` in a project that uses `zod@3` we are running into TypeScript errors like: ``` node_modules/babel-plugin-react-compiler/dist/index.d.ts:435:10 - error TS2694: Namespace '"/REDACTED/node_modules/zod/v3/external"' has no exported member 'core'. 435 }, z.core.$strip>>>; ~~~~ ``` This problem seems to be related to d6eb735938, which introduced zod v3/v4 compatibility. Since `zod` is bundled into the compiler source this does not cause runtime issues and only manifests as TypeScript errors. My proposed solution is this PR is to use zod's [subpath versioning strategy](https://zod.dev/v4/versioning?id=versioning-in-zod-4) which allows you to support v3 and v4 APIs on both major versions. Changes in this PR include: - Updated `zod` import paths to `zod/v4` - Bumped min `zod` version to `^3.25.0` for zod which guarantees the `zod/v4` subpath is available. - Updated `zod-validation-error` import paths to `zod-validation-error/v4` - Bumped min `zod-validation-error ` version to `^3.5.0` - Updated `externals` tsup configuration where appropriate. Once the compiler drops zod v3 support we could optionally remove the `/v4` subpath from the imports. ## How did you test this change? Not totally sure the best way to test. I ran `NODE_ENV=production yarn workspace babel-plugin-react-compiler run build --dts` and diffed the `dist/` folder between my change and `v1.0.0` and it looks correct. We have a `patch-package` patch to workaround this for now and it works as expected. ```diff diff --git a/node_modules/babel-plugin-react-compiler/dist/index.d.ts b/node_modules/babel-plugin-react-compiler/dist/index.d.ts index 81c3f3d..daafc2c 100644 --- a/node_modules/babel-plugin-react-compiler/dist/index.d.ts +++ b/node_modules/babel-plugin-react-compiler/dist/index.d.ts @@ -1,7 +1,7 @@ import * as BabelCore from '@babel/core'; import { NodePath as NodePath$1 } from '@babel/core'; import * as t from '@babel/types'; -import { z } from 'zod'; +import { z } from 'zod/v4'; import { NodePath, Scope } from '@babel/traverse'; interface Result<T, E> { ``` Co-authored-by: Henry Q.
