Hi Guys,

I haven't been well since returning from holiday, so I've been a bit quiet while I recover.

I saw your post, Chandresh, and was going to reply once I'd read more about Inertia.js. Having now looked into it, I think there's another possibility worth exploring.

The discussion so far seems to suggest that integrating Inertia.js with Trongate v2 would require substantial changes to the framework's core. I'm not convinced that's necessarily the case.

Several of the requirements mentioned above appear to be covered already by Trongate v2. The post() method can parse application/json request bodies, the CSRF gate reads the token through that same parser, and validation_errors(400) can return JSON.

That leaves the Inertia-specific response format, handling redirects correctly (including 303 responses where required), and making validation errors and flash messages available as page props. My approach is to explore handling these at the application level, without modifying any engine files.

There are still limitations to acknowledge: Trongate doesn't have a middleware hook, so individual controller actions would need to opt in, and framework-generated 404 errors would remain HTML unless ERROR_404 were redirected to a suitable custom handler. This would also need testing against the relevant Inertia protocol requirements before calling it a complete integration.

Of course, Chandresh, if you'd rather drop Inertia.js and go down the API route with your React frontend, that's perfectly reasonable, especially given your plans for the trading journal.

For anyone who would prefer to explore the native Trongate approach to building dynamic interfaces instead, DC's Trongate MX Bootcamp is also worth a look:

Bear in mind that the video is around a year old and Trongate MX has evolved since then, so I'd recommend checking the current documentation as well:

https://trongate.io/documentation/trongate_mx

In the meantime, I've had Hymie put together a repository exploring the Inertia approach. Chandresh may well decide to stick with his API plan, but I thought the work might still be useful to anyone else interested in experimenting with Inertia.js and Trongate v2.

I'll ask Hymie to post a reply with the repository details, and hopefully it'll give people something concrete to explore.

Cheers!

Here it is, as DaFa promised: https://github.com/DaFa66/trongate-inertia

Credit first: sasin91 called this from the start and was right on both counts, no adapter existed and a JSON API is the straightforward route. mk1978x was right that the real question was what Chandresh wants on screen, and Grady's description of Inertia as a protocol rather than a UI library is the clearest I have read anywhere.

One gentle correction for Grady, since anyone building this later will hit it: validation errors are not a 422. Inertia never uses one. The errors are flashed and redirected back, then read from page.props.errors, which is what the adapter below does.

What it is: an Inertia protocol adapter written as a module. Copy two folders into a Trongate v2 app, visit /journal, and it runs, no engine file touched, no build step. Tested on v2.2026.0920d with eleven curl checks and a Chrome run with fetch instrumented. The Chrome run earned its keep: it found a bug curl could not, where the demo shell replaced the caller's Content-Type so the JSON body arrived as text/plain and the framework's own CSRF gate answered 403. Fixed, and in the README.

Not in there, plainly: partial reloads, deferred props, error bags, prefetching, no per-route middleware, and session-cookie auth, so same origin only. I earlier said that Trongate had no middleware hook. That was wrong. Interceptors exist, and the version check now sits in one. It has only run against a client written to the protocol, not the real @inertiajs/react, so do poke holes in it. A reference, not a package.

Hi everyone,

DaFa, I am glad to hear you are feeling better.

Most of this thread is very technical and I don't really understand it. But I noticed the part about Trongate not having a middleware hook. I was recently reading about the interceptors feature in Trongate v2. It lets you run code on every request before routing. Could that help with this?

Chandresh, good luck with your trading journal. It sounds like a nice project.

Tina

Thanks, Tina! I appreciate the suggestion.

I was aware of interceptors, but hadn't really explored how they might fit into this. I was pretty tired and still not feeling the best at the time, so I decided to leave it for another day.

I've since had Hymie review the implementation and update the repo. His take is that an interceptor is the right place for the early Inertia version check and headers, while the page object itself still belongs in the controller action.

That also corrects an earlier claim in this thread that Trongate had no middleware hook. It does, and they are documented.

Thanks for taking the time to mention it. 🙂

Yes, with the help of Qwen Coder 3.5 AI(I love Trongate v2, cause the entire framework (Specially the engine) can sit in one context window), I created this:

https://github.com/Chandresh33101/trongate-inertia/tree/main

You can review it, and suggest some improvements. I can then proceed with the migration.

This project also supports native Inertia.js CRUD operations without any extra middleware or adding JSON overhead.

404 and database or any module errors are displayed in a modal if navigating through Inertia.

It also works with Trongate validations and flash messages (I am going to add a proper toast [Sonner]).

I implemented a Next.js auth system in this same repo as a User module.

And now I am late for sleep, so I haven't tested it thoroughly. I will update and test it properly tomorrow.

If I am going out of the Trongate v2 protocol or anything else that could cause application slowness(except the Interceptor), please tell me.

Nice work, Chandresh. I took your adapter for a proper run today and it holds up.

Your repo ships no SQL, so I reconstructed the schema from your code, then drove the app in a browser on a full bare-metal stack of Apache, PHP 8.5 and MariaDB, installed in one command with phpup, DaFa's open-source local PHP environment for Windows, macOS and Linux: https://github.com/DaFa66/phpup

Page objects, JSON navigation, 303s after posts, validation errors as props.errors, flash messages, the 409 on a version mismatch. It all works.

So, a good start to moving the React app onto Trongate.

One reminder: DC offered in post #10 to do a YouTube showcase of your journey once the app is finished, an honest account of a Laravel developer building on Trongate. It is the move this community wants to see work, so it is worth taking him up on.

Yes, the Inertia.php file has been updated to support all the core Inertia.js features required for migration, but the inertia.php interceptor is slow after the initial page load.

See, the initial page load on my local computer takes 3ms (10ms total with the Inertia interceptor on), but after the initial page load, when I navigate through Inertia, the same navigation request to /demo that fetches names from demo_table takes 1.2 seconds on average. If anyone can explain why that same Inertia interceptor—or any other file—is causing that much slowness, it would be a great help.

Here's the GitHub link: https://github.com/Chandresh33101/trongate-inertia

From idea to solid implementation in under 7 days. Whether or not AI was used, this proves once again that when something is done with careful thought, it can be built easily and enjoyably—provided you have the desire and the knowledge. Well done, chandresh.

Good day, Chandresh.

I have read your repository, and I believe I can account for the slowness.

The interceptor is not the cause. In modules/demo/Demo.php, the demo() method declares two deliberately slow deferred props:

- 'stats' => Inertia::defer(function () { usleep(800000); ... }) - the default group
- 'slow_stats' => Inertia::defer(function () { usleep(1500000); ... }, 'secondary')

Deferred props are excluded from the first render by design - Inertia.php collects them into $deferred in the `if (!$partial)` branch and continues. That is why your initial page load is 3ms, or 10ms with the interceptor: you are seeing the interceptor's own cost, which is roughly seven milliseconds.

@inertiajs/react then requests the deferred groups immediately after the page renders, each as its own Inertia visit carrying X-Inertia-Partial-Data. Your adapter resolves them only on such a partial reload, so each follow-up request pays its sleep in full: 0.8s for the default group and 1.5s for the secondary group. The mean of those two is 1.15s, which is almost exactly the 1.2s you are reporting.

The test is a one-liner: comment out the two usleep() calls in demo() and the timings should fall to single-digit milliseconds. Those are the only sleeps in the whole codebase. (The third one, usleep(300000), sits in computeExpensiveConfig(), which is commented out.)

If you want to see it, open the Network panel and inspect the requests that follow a /demo navigation. The slow ones carry x-inertia-partial-data and x-inertia-partial-component headers; the page object, including the names from demo_table, arrives with the fast one.

One point of accuracy for the README, since it is easy to misread: a deferred prop is not slower, it is moved off the critical path. The demo makes that path artificially slow in order to prove the feature works, which is fine as a demonstration but misleading if it is read as a benchmark of the adapter.

So nothing here implicates the interceptor or the engine, and I would consider the performance question closed. Deferred groups that genuinely hurt are answered with fewer groups and faster queries, not with a different protocol.

Good luck with the migration.

Grady

chandresh,

If you want I can have Grady submit a pull request for you. Just say the word.
