Laravel Weekly Update #10: Precognition

[@aghitsnidallah7953]

How is this Precognition works in the background? Implying the requests is sent every time the input blurs, will it impact the low-end server performance?

[@timacdonald]

Tim here, creator of this feature for the team. That really depends on your server and application context (user load, etc.). You don't have to use Precognition on all forms and for forms where you do use it, you may also "sprinkle" Precognition onto forms where it makes sense. You could use Precognition to validate only the email address and it won't send a request when the "name" field is blurred, for example.

@@timacdonald Hi, thanks a lot for the reply. It's a relief to know.

Absolute goats who made this! We had some troubles when working with our headup setup between the frontend and senior engineers, both had to duplicate rules which caused some issues.

That's a great feature. A quick question, seems like this is only applicable for web routes, will it be or could it be applied for API routes?

[@timacdonald]

Tim here, creator of this feature for the team. You could absolutely add this to an API route! This was something I played around with during development of the feature.

Do we really need it for the API? Because they will get the response of validation on submission

[@timacdonald]

@@vinit095 You don't _need_ it in either case, however using it on your API would allow 3rd party applications to also provide live validation - if that is something you wanted.

[@MatteoPresot]

What about fortify or breeze? Are they already compatible? Is there any drawback on putting a single Precognition Middleware in front of all routes?

[@fenilli]

Quick question if both name and email where added to precognition, will it sent two requests when those values change? will it cancel previous ones and add all in one request? and if so, if I keep changing the first field before the timeout runs, will the second field be also waiting for the response to show validation for both at the same time?

[@maximmaxim1074]

But I can also make an event listener on focus out sending a post request to check if email is available?

[@vinit095]

This feature is quite good

[@danmatthews3431]

It's a perfect fit for some forms we're moving from Livewire to Inertia + Svelte, will the source code be available at some point so we can look at building an Adapter for it that we could share with the community?

[@timacdonald]

The repository is public. laravel/precognition

[@bulent2435]

That looks awesome.

[@bimasakti-nb2el]

Are this support inertia v1.0?

[@SmailPeche]

nice feature, what about blade if i don't work with vue js ? any help please ?!

[@timacdonald]

There is an Alpine version available, otherwise it is possible to use with vanilla JS, but we don't have an approach documented.
