Name: valibot_migrate_to_v0_31_0 codemod
Availability: InStock

This codemod automatically migrates your Valibot codebase to version 0.31.0, handling all breaking changes introduced in this release.

What it migrates

Schema renames: custom → check, Input → InferInput, Output → InferOutput
Object merging: merge → object
Objects/tuples with rest: Transforms objectWithRest and tupleWithRest to new syntax
Loose/strict variants: Converts looseObject/strictObject and looseTuple/strictTuple to new API
Pipeline API: Migrates array-based pipelines to pipe() function calls
Method transformations: Updates coerce, flatten, brand, and transform method calls
Nested pipes: Flattens deeply nested schema compositions into cleaner pipe() chains

Example

Before (v0.30):

typescript
const schema = v.brand(
  v.transform(
    v.string([v.trim()]),
    (s) => s.toLowerCase()
  ),
  'ProcessedString'
);

After (v0.31):

typescript
const schema = pipe(
  string(),
  transform((s) => s.trim()),
  transform((s) => s.toLowerCase()),
  brand('ProcessedString')
);
