Safe Actions

The safe-actions.ts module provides type-safe server actions with built-in authentication, authorization, and error handling using next-safe-action.

Available Clients

action - Public Actions

Base client for public actions that don't require authentication.

import { action } from "@/lib/actions/safe-actions";

export const subscribeNewsletter = action
  .inputSchema(
    z.object({
      email: z.string().email(),
      name: z.string().optional(),
    }),
  )
  .action(async ({ parsedInput: { email, name } }) => {
    await addToNewsletter(email, name);
    return { subscribed: true };
  });

authAction - Authenticated Actions

Requires a valid user session. Provides ctx.user in the handler.

import { authAction } from "@/lib/actions/safe-actions";

export const updateProfile = authAction
  .inputSchema(
    z.object({
      name: z.string().min(1),
      bio: z.string().optional(),
    }),
  )
  .action(async ({ parsedInput: { name, bio }, ctx: { user } }) => {

orgAction - Organization Actions

Requires organization membership with optional role/permission checks. Provides ctx.org in the handler.

import { orgAction } from "@/lib/actions/safe-actions";

// With permissions
export const inviteUser = orgAction
  .metadata({ permissions: { users: ["create", "invite"] } })
  .inputSchema(
    z.object({
      email: z.string().email(),
      role: z.enum(["member", "admin"]),
    }),
  )
  .action(async ({ parsedInput: { 

adminAction - Admin-Only Actions

Requires the user to have admin role. Provides ctx.user in the handler.

import { adminAction } from "@/lib/actions/safe-actions";

export const updateSubscriptionPlan = adminAction
  .inputSchema(
    z.object({
      organizationId: z.string(),
      planName: z.string(),
    }),
  )
  .action(
    async ({ parsedInput: { organizationId, planName }, ctx: { user } }) => {
      await updateOrgPlan(organizationId, planName);

Error Handling

All clients use a shared error handler that:

• Returns ApplicationError messages to the client
• Logs unknown errors
• Returns generic message in production for security
• Returns full error message in development for debugging

Usage with TanStack Form

Use resolveActionResult to integrate with forms:

import { resolveActionResult } from "@/lib/actions/actions-utils";
import { updateProfile } from "./profile.action";

const form = useForm({
  schema: ProfileSchema,
  defaultValues: { name: "", bio: "" },
  onSubmit: async (values) => {
    const result = await resolveActionResult(updateProfile(values));
    // result is typed, throws on error
  },
});

File Naming Convention

Server action files should be suffixed with .action.ts:

• user.action.ts
• dashboard.action.ts
• organization.action.ts
