packages/babel-types/src/builders/index.ts

+
+export function buildUndefinedNode() {
+  return unaryExpression("void", numericLiteral(0), true);
+}


Can we rename this file to builders/productions.ts? In this case the index.ts is for aggregating all the exports from sub modules: flow, generated, react, productions.

We can add more productions as well, such as !0 as true literal and !1 as false.

packages\babel-types\src\index.ts
Unfortunately currently we aggregate the exports of all submodules in this file.🤦‍♂️
It would be a bit inconsistent if we just changed this.

This seems to break compatibility between @babel/traverse and @babel/types meaning that upgrading traverse without also updating types results in errors such as this during import:

TypeError: /path/to/foo.tsx: buildUndefinedNode is not a function

...

  at Scope.buildUndefinedNode (@babel-traverse-npm-7.23.2-4758feee42-26a1eea0dd.zip/node_modules/@babel/traverse/src/scope/index.ts:786:12)
  at buildUndefinedNode (@babel-helper-module-transforms-npm-7.21.2-c33f2d2d0e-8a1c129a4f.zip/node_modules/@babel/helper-module-transforms/src/index.ts:509:31)

The @babel/traverse dependencies use a workspace:^ e.g. here

babel/packages/babel-traverse/package.json

Line 26 in 3688240

"@babel/types": "workspace:^",

which AIUI means it's saying future minor/patch versions will be compatible - this PR appears to break that compatibility?

No, it means "@babel/types": "^7.23.0",, I think your problem may come from you pinning @babel/types.

which AIUI means it's saying future minor/patch versions will be compatible

Yes, that's right. This PR made new @babel/traverse versions depend on @babel/types ^7.23.0, but old @babel/traverse versions still work with both old and new @babel/types versions, without breaking compatibility. Can you share your lockfile?

meaning that upgrading traverse without also updating types results in errors

Yes, but @babel/traverse defines @babel/types in its dependencies and thus, unless there is something buggy going on with your package manager (or with your config explicitly telling the package manager to ignore that dependency) upgrading traverse will force-upgrade types.

Yes apologies this was an error on my end, sorry for the noise!
