fix(actions): support for nested objects in form by seroperson · Pull Request #15978 · withastro/astro

seroperson · 2026-03-18T07:46:57Z

Closes #14387

Changes

Added support for nested objects with dot notation in form data parsing
formDataToObject now recursively processes nested ZodObject schemas, converting dot-notation form keys (like bc.b) into nested object structures ({ bc: { b: ... } })

Testing

Covering most of cases I could imagine in form-data-to-object.test.js: nested objects, superRefine wrapping, deeper 3-level nesting, optional/nullable/default nested objects, nested discriminatedUnion
Several new integration tests in actions.test.js: nested form objects, superRefine validation, nested discriminatedUnion

Docs

No new API was introduced, so likely no docs changes are required

I don't love all of the Zod internals stuff happening here, but we were already doing the same thing as before, so no worse.

@seroperson can you resolve the conflicts please? then can get this merged.

This PR is marked as minor, so:

I block it until we're ready to ship it
I would love if the changeset would be more user focused.

Is this supposed be a minor or should it be a patch? Nevertheless the changeset should be more descriptive

Closes withastro#14387

@ematipico I've re-marked it as patch (as it's a bugfix actually. probably misclicked the first time) and made the changeset more descriptive

The duplicate slashes are now collapsed before URL parsing, preventing them from being interpreted as a protocol-relative URL. ### [`v6.0.7`](https://github.com/withastro/astro/blob/HEAD/packages/astro/CHANGELOG.md#607) [Compare Source](https://github.com/withastro/astro/compare/astro@6.0.6...astro@6.0.7) ##### Patch Changes - [#15950](withastro/astro#15950) [`acce5e8`](withastro/astro@acce5e8) Thanks [@matthewp](https://github.com/matthewp)! - Fixes a build regression in projects with multiple frontend integrations where `server:defer` server islands could fail at runtime when all pages are prerendered. - [#15988](withastro/astro#15988) [`c93b4a0`](withastro/astro@c93b4a0) Thanks [@ossaidqadri](https://github.com/ossaidqadri)! - Fix styles from dynamically imported components not being injected on first dev server load. - [#15968](withastro/astro#15968) [`3e7a9d5`](withastro/astro@3e7a9d5) Thanks [@chasemccoy](https://github.com/chasemccoy)! - Fixes `renderMarkdown` in custom content loaders not resolving images in markdown content. Images referenced in markdown processed by `renderMarkdown` are now correctly optimized, matching the behavior of the built-in `glob()` loader. - [#15990](withastro/astro#15990) [`1e6017f`](withastro/astro@1e6017f) Thanks [@ematipico](https://github.com/ematipico)! - Fixes an issue where `Astro.currentLocale` would always be the default locale instead of the actual one when using a dynamic route like `[locale].astro` or `[locale]/index.astro`. It now resolves to the correct locale from the URL. - [#15990](withastro/astro#15990) [`1e6017f`](withastro/astro@1e6017f) Thanks [@ematipico](https://github.com/ematipico)! - Fixes an issue where visiting an invalid locale URL (e.g. `/asdf/`) would show the content of a dynamic `[locale]` page with a 404 status code, instead of showing your custom 404 page. Now, the correct 404 page is rendered when the locale in the URL doesn't match any configured locale. - [#15960](withastro/astro#15960) [`1d84020`](withastro/astro@1d84020) Thanks [@matthewp](https://github.com/matthewp)! - Fixes Cloudflare dev server islands with `prerenderEnvironment: 'node'` by sharing the serialized manifest encryption key across dev environments and routing server island requests through the SSR runtime. - [#15735](withastro/astro#15735) [`9685e2d`](withastro/astro@9685e2d) Thanks [@fa-sharp](https://github.com/fa-sharp)! - Fixes an EventEmitter memory leak when serving static pages from Node.js middleware. When using the middleware handler, requests that were being passed on to Express / Fastify (e.g. static files / pre-rendered pages / etc.) weren't cleaning up socket listeners before calling `next()`, causing a memory leak warning. This fix makes sure to run the cleanup before calling `next()`. </details> --- ### Configuration 📅 **Schedule**: Branch creation - At any time (no schedule defined), Automerge - At any time (no schedule defined). 🚦 **Automerge**: Disabled by config.
