Hi @naive fiber. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
#Correct type for setting state with astro actions
round stratusBOT
Astro actions are a way to write type-safe backend functions that you can call from anywhere. When defining an action, you can use the input property to validate parameters with Zod. However, the knowledge sources provided do not specifically mention the type for setting state for ActionErrors via const {data, error} = actions.myAction.safe(formData).
Here's an example of defining actions from the provided knowledge sources:
import { defineAction, z } from "astro:actions";
export const server = {
like: defineAction({
input: z.object({ postId: z.string() }),
handler: async ({ postId }) => {
// update likes in db
return likes;
},
}),
comment: defineAction({
accept: 'form',
input: z.object({
postId: z.string(),
author: z.string(),
body: z.string(),
}),
handler: async ({ postId }) => {
// insert comments in db
return comment;
},
}),
};
In this example, the input property is used to validate parameters with Zod. However, the type for setting state for ActionErrors is not specified.
For more detailed information, you may want to refer to the Astro documentation (https://docs.astro.build/en/reference/configuration-reference/#experimentalactions).

@round stratus , so when I call the action in my handler from my React component via:
const handleLogin = () => {
const formData = new FormData(formRef.current as HTMLFormElement);
const { data, error } = await actions.users.login.safe(formData);
const inputErrors = isInputError(error) ? error.fields : {};
}
I need to set the inputErrors to state so I can display them. Does astro actions export a type to use, and if not, what would be the correct type to use to set my state too?

Let me check the knowledge base for you. One moment! :books:
Based on the provided knowledge sources, Astro does not explicitly provide a type for handling errors when using Astro actions. However, in your React component, you can define the state for inputErrors using the useState hook and set its initial type based on your requirements.
Here's an example of how you might do this:
import { useState } from "react";
// Define your state
const [inputErrors, setInputErrors] = useState({});
const handleLogin = async () => {
const formData = new FormData(formRef.current as HTMLFormElement);
const { data, error } = await actions.users.login.safe(formData);
const errors = isInputError(error) ? error.fields : {};
// Set the state
setInputErrors(errors);
}
In this example, inputErrors is initialized as an empty object, and its type would be inferred based on the values you set it to. If error.fields returns an object, inputErrors would be of type object.

@round stratus , Thanks for that. However, What would I set the "useState"'s type too ?

In TypeScript, you can define the type for the state when using the useState hook. However, the exact type for inputErrors would depend on the structure of error.fields in your application.
If error.fields is an object where the keys are strings and the values are also strings (for example, field names mapped to error messages), you could define the state like this:
const [inputErrors, setInputErrors] = useState<Record<string, string>>({});
In this example, Record<string, string> represents an object where keys and values are both strings.
If the structure of error.fields is more complex, you would need to define an interface that matches this structure and use that as the type. For example:
interface ErrorFields {
[key: string]: string | string[]; // adjust this based on your actual structure
}
const [inputErrors, setInputErrors] = useState<ErrorFields>({});
In this example, ErrorFields represents an object where keys are strings and values can be either strings or arrays of strings.
Please adjust these examples based on the actual structure of error.fields in your application. If you're unsure about the structure, you might want to log error.fields to the console to inspect it.

@round stratus , does astro:actions provide a type for this by default?
round stratusBOT
Let me check the knowledge base for you. One moment! :books:
Based on the provided knowledge sources, there is no explicit mention of a default type provided by astro:actions for handling errors or setting state in React. The astro:actions module is primarily used to define server-side actions and their input validation.
In TypeScript, the type of the error or state would typically be defined based on the structure of the data your application is working with. If astro:actions does provide a specific type for this, it is not mentioned in the provided sources.
