graphql-codegen patch

We maintain a pnpm patch against [email protected] to add @oneOf directive support for Zod schema generation, sourced from Jabolol/graphql-codegen-typescript-validation-schema on branch jabolol/one-of-directive-support.

Relevant files:

  • Patch: apps/frontend/patches/[email protected]
  • Config: pnpm-workspace.yaml → patchedDependencies
  • Fork changes: src/zod/index.ts, src/zodv4/index.ts

Regenerating the patch​

Clone/update the fork, build it, then:

# From OSO repo root
pnpm patch [email protected]

# Copy the six changed dist files into <TEMP_DIR>
FORK=/path/to/fork
TEMP=<TEMP_DIR>
for dir in cjs esm; do
  cp $FORK/dist/$dir/zod/index.js   $TEMP/dist/$dir/zod/index.js
  cp $FORK/dist/$dir/zodv4/index.js $TEMP/dist/$dir/zodv4/index.js
done
cp $FORK/dist/types/zod/index.d.ts   $TEMP/dist/types/zod/index.d.ts
cp $FORK/dist/types/zodv4/index.d.ts $TEMP/dist/types/zodv4/index.d.ts

pnpm patch-commit '<TEMP_DIR>'

cd apps/frontend && pnpm graphql:codegen

Dropping the patch​

Once upstream ships @oneOf support, remove patchedDependencies from pnpm-workspace.yaml, delete the patch file, and bump the version in apps/frontend/package.json.
