feat!: Inertia v3 parity (client 3.8), DevTools, dependency update — 0.2.0 - #4
Conversation
…, dependency update Brings the protocol surface up to the current Inertia v3 spec (https://inertiajs.com/docs/v3/core-concepts/the-protocol), checked against the inertia-laravel 3.x source and the real client in a browser. Protocol - X-Inertia-Version on the version-mismatch 409 - 409 + X-Inertia-Redirect for redirects with a URL fragment - page JSON in the HTML shell escapes `<`, `>` and `/` - flash data is the top-level `flash` field and survives redirect chains, plain responses and the version 409 - error bags, sharedProps, preserveFragment, Vary on all responses - an empty 200 to an Inertia request redirects back Props - `Prop`: composable closure prop (optional, defer, once, merge, prepend, deep merge, match-on, rescue, infinite scroll, nested dot paths) - partial reloads: dot paths, `errors` always sent, except-only reloads, reset removes merge labels - big integers as `$bigint` markers Other - Precognition: `Inertia::precognition()` + `Precognition::respond` - DevTools protocol: recorder, headers, read API (`InertiaConfig::devtools`) - all validation messages per field (`with_all_errors`) - SSR client: timeout, health check, error detail - validator 0.21, ts-rs 12, base64 0.23, getrandom 0.4 - example: showcase page, Precognition, Inertia 3.7, Vite 8.3, TypeScript 7 BREAKING CHANGE: flash moves from `props.flash` to the page's `flash`; `reset_merge` / `resetMergeProps` are removed; `location()` returns 302 for non-Inertia requests; `LazyProp` / `DeferredProp` are replaced by `Prop`; `Flash::errors` holds a list per field; the `ts` feature needs ts-rs 12. See CHANGELOG.md.

…rdening - closure props return any `Serialize` value; `register_page!` takes a third argument that gives closure props their TypeScript types - `InertiaConfig::store_previous_url`: `Inertia::back` uses the session's previous URL when the request has no `Referer` - DevTools recorder is behind the `devtools` Cargo feature; entries carry the source location of the `render` call - wrapper marker keys get a random suffix per process, so user data cannot name them - `veer::Head` for the client's `serverHead` option - a Precognition request with a rejected body still gets a Precognition response - example: typed closure props, a big-integer prop, Inertia client 3.8.0; the CSR bootstrap lets the client parse the first page itself

…cognition - the previous URL is no longer part of `Flash`: `SessionStore` has `previous_url` / `store_previous_url` (defaults keep nothing). The cookie store uses its own signed cookie; flash data keeps its 60 s life and plain responses no longer rewrite the session - the URL of each page visit is stored (also the first HTML load), except `//host` targets and URLs over 2048 bytes; the empty-200 redirect uses it - `Merge` / `Always` wrappers inside a closure prop's value are stripped and labelled (they reached the client as marker objects) - remove the Precognition fallback in the layer: it could replace a handler's own 422 body and report a rejected body as valid - a nested `Always` under an unselected parent is not sent: the client replaces top-level props, so a partial parent would lose its other fields - `InertiaMiddleware` drives the service instance that `poll_ready` readied - docs: Precognition notes, session store methods, wrapper behavior

Prune closure results for nested partial filters.
The resolver selects a closure by its top-level key, then inserts its full returned object. For only: ['feed.data'] or except: ['feed.secret'], this sends unrequested siblings and can replace the client’s existing top-level feed value. Prune object results by the closure key before insertion, while preserving root Always behavior. Closure Merge metadata is already filtered by path.
