Best way to handle server action

[grim crow]

what's the best way to handle Next.js Server Actions to track pending states and trigger post-completion tasks (e.g., redirects)? I’m considering TanStack Query and next-safe-action—which library is more beneficial for this use case, and why?

Hi @grim crow. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

Based on the knowledge sources provided, I can offer some insights on handling Next.js Server Actions, particularly for tracking pending states and managing post-completion tasks like redirects. However, the sources don't contain specific information about TanStack Query or next-safe-action libraries for this purpose.

For handling pending states and post-completion tasks with Next.js Server Actions, the recommended approach is to use React's built-in hooks and Next.js functions:

1. Pending States:
   React provides the useActionState hook for managing the state of Server Actions, including handling pending states. Here's an example of how to use it:

   'use client'
   
   import { useActionState } from 'react'
   import { createUser } from '@/app/actions'
   
   const initialState = {
     message: '',
   }
   
   export function Signup() {
     const [state, formAction, pending] = useActionState(createUser, initialState)
   
     return (
       <form action={formAction}>
         <label htmlFor="email">Email</label>
         <input type="text" id="email" name="email" required />
         {/* ... */}
         <p aria-live="polite">{state?.message}</p>
         <button disabled={pending}>Sign up</button>
       </form>
     )
   }
   

   This approach allows you to disable the submit button while the action is pending and display any messages returned from the server action Server Actions and Mutations.

2. Post-completion tasks (e.g., redirects):
   For tasks like redirecting after a successful action, you can use the redirect function from Next.js directly in your server action:

   'use server'
   
   import { redirect } from 'next/navigation'
   
   export async function createPost(formData: FormData) {
     // Mutate data
     // ...
   
     redirect('/posts')
   }

This will automatically redirect the user after the server action completes successfully Server Actions and Mutations.

It's worth noting that these built-in solutions are designed to work seamlessly with Next.js and React, providing a clean and efficient way to handle server actions without additional libraries.

The knowledge sources don't provide information about TanStack Query or next-safe-action in the context of Server Actions, so I can't make a comparison or recommendation between these libraries and the built-in Next.js approach. If you're considering using these libraries, you might want to review their documentation and compare their features with the built-in Next.js functionality to determine which best suits your specific needs.

Note: you can ask me a follow up question by @ mentioning me again :speech_balloon:
