Hi @stoic island. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
#Get # or ? from URL
robust basinBOT
In Astro, you can access the URL object from the context in your server-side code. The URL object is constructed from the current context.request.url URL string value. This object includes properties such as hash and searchParams which can be used to access the # fragment or the ? query parameters respectively.
Here is an example of how you might use it:
let hash = context.url.hash; // gets the URL fragment after '#'
let location = context.url.searchParams.get('location'); // gets the 'location' query parameter
Please note that the context.url is a standard URL (https://developer.mozilla.org/en-US/docs/Web/API/URL) object, and you can refer to its documentation for more details.
For more information, you can refer to the Astro API Reference (https://docs.astro.build/en/reference/api-reference/#contexturl).
Note: you can ask me a follow up question by @ mentioning me again :speech_balloon:

@robust basin Context is seemingly not a thing
robust basinBOT
Let me check the knowledge base for you. One moment! :books:
In Astro, context is indeed a thing. It's an object that's passed as the first parameter to endpoint functions and it mirrors many of the Astro global properties. It's also used in middleware functions.
Here's an example of how it's used in an endpoint function:
import type { APIContext } from 'astro';
export function GET(context: APIContext) { // ...}
And here's an example of how it's used in a middleware function:
export function onRequest (context, next) {
// intercept data from a request
// optionally, modify the properties in `locals`
context.locals.title = "New title";
// return a Response or the result of calling `next()`
return next();
};
In these examples, context is used to access request data and modify response data.
For more information, you can refer to the Astro API Reference (https://docs.astro.build/en/reference/api-reference/#endpoint-context) and the Astro Middleware Guide (https://docs.astro.build/en/guides/middleware/#basic-usage).

@robust basin Is there a way to use process.env in a .astro file
robust basinBOT
Let me check the knowledge base for you. One moment! :books:
Yes, you can use environment variables in Astro files using import.meta.env. However, for security reasons, only environment variables prefixed with PUBLIC_ are available in client-side code.
Here's an example of how you can use it:
---
const publicVar = import.meta.env.PUBLIC_VAR;
---
<h1>{publicVar}</h1>
In this example, PUBLIC_VAR is an environment variable that you've defined in your .env file or in your environment.
Remember, environment variables are statically replaced at build time. If you want to use environment variables server-side, you can use import.meta.env or process.env depending on the context.
For more information, you can refer to the Astro Environment Variables Guide (https://docs.astro.build/en/guides/environment-variables/).

@robust basin I dont want to have the User be able to see the variable i just want it in my
function here

In Astro, you can use environment variables in the server-side part of your .astro file. However, you should not use import.meta.env to access environment variables that were set in .env files in the server-side script section of your .astro file.
Astro evaluates configuration files before it loads your other files. As such, you can’t use import.meta.env to access environment variables that were set in .env files. You can use process.env in a configuration file to access other environment variables, like those set by the CLI.
Here's an example of how you can use it:
---
const secretVar = process.env.SECRET_VAR;
---
<h1>Secret variable is used server-side</h1>
In this example, SECRET_VAR is an environment variable that you've defined in your .env file or in your environment.
Remember, environment variables are statically replaced at build time. If you want to use environment variables server-side, you can use import.meta.env or process.env depending on the context.
For more information, you can refer to the Astro Environment Variables Guide (https://docs.astro.build/en/guides/environment-variables/).

Gives me as the Title Weather for [object Object] any idea?

Let me check the knowledge base for you. One moment! :books:
The issue you're encountering is due to the await keyword in your location assignment. The URLSearchParams.get() method is synchronous and does not return a Promise, so there's no need to use await.
Here's how you should modify your code:
---
const url = new URL(Astro.request.url);
const location = url.searchParams.get('location') || 'World';
console.log(location);
const secretVar = import.meta.env.WEATHER_API;
console.log(secretVar);
