Nohup com env em shell
TODO: collapasable, copyable, download, etc
I am starting a process with ENV variables inline... how would I change this to use it with nohup?
AUTH_ADMIN_PASSWORD=ab343ret AUTH_SECRET=98db4f30dc8c6e9f9d696d2c862c1 PORT=5173 node build
To start a process with environment variables inline using nohup
, you can use a shell to wrap your command, allowing you to set the environment variables before executing the command with nohup
. This ensures that the process continues running in the background even after the terminal is closed. You can do this by using the env
command or by setting the variables in a sub-shell. Here's how you can modify your command to use it with nohup
:
Using env
Command
You can prefix your command with env
to set the environment variables, and then use nohup
to run the process in the background:
nohup env AUTH_ADMIN_PASSWORD=ab343ret AUTH_SECRET=98db4f30dc8c6e9f9d696d2c862c1 PORT=5173 node build &
Using a Sub-Shell
Alternatively, you can use a sub-shell to set the environment variables and run your command. This is done by enclosing your variable assignments and command within parentheses, prefixed by nohup
:
nohup sh -c 'AUTH_ADMIN_PASSWORD=ab343ret AUTH_SECRET=98db4f30dc8c6e9f9d696d2c862c1 PORT=5173 node build' &
In both methods, the &
at the end of the command is used to run the process in the background.
After running your command with nohup
, the output of the command will be redirected to a file named nohup.out
in the directory where the command was run, unless otherwise specified. You can also redirect the output to a different file by adding > output.log 2>&1
at the end of the command, replacing output.log
with your desired file name. This will redirect both stdout and stderr to your specified file.For SvelteKit, where do I put some code that would run on every request?In SvelteKit, to execute code on every request, you would use the concept of "hooks". Hooks in SvelteKit are functions that run at various points during a request's lifecycle. Specifically, you would use the handle
hook to run code on every request. This hook allows you to process the request before it reaches any endpoints or page rendering logic, and also to modify the response that gets sent back.
The handle
hook is defined in the hooks.ts
(or hooks.js
if you're using JavaScript) file located in the src
directory, typically under src/hooks
.
Here's a basic example of how you might set up a handle
hook in src/hooks.ts
:
import type { Handle } from '@sveltejs/kit';
export const handle: Handle = async ({ request, resolve }) => {
// Your code here will run for every request
// For example, you could add a custom header to every response
// or perform some authentication/authorization checks
// Continue processing the request
const response = await resolve(request);
// Optionally modify the response here
// For example, adding a response header
response.headers['x-custom-header'] = 'value';
return response;
};
In this example, the handle
function takes an object with request
and resolve
properties. The request
object contains details about the incoming request, and resolve
is a function that you call to proceed with the normal handling of the request (such as rendering a page or invoking an endpoint). After calling resolve
, you can still modify the response before it is sent back.
This hook is a powerful feature that allows you to implement global logic such as:
- Logging
- Authentication and authorization
- Custom headers manipulation
- Redirects
- Server-side analytics or tracing
Always remember to call and return resolve(request)
within your handle
hook to ensure that the request continuesThis is my current Hook - /** @type {import('@sveltejs/kit').Handle} */
export const handle = SvelteKitAuth({
trustHost: true,
providers: providers,
secret: AUTH_SECRET,
pages: { error: '/auth_error' }
});
How do I change that so I have a place to put my codeTo modify your current SvelteKit hook to include a place for your custom code, you can wrap the SvelteKitAuth
call within your own handle
function. This way, you can execute additional code before or after the authentication logic provided by SvelteKitAuth
. Here's how you could structure your modified hook:
// Import the necessary types for TypeScript support
/** @type {import('@sveltejs/kit').Handle} */
// Assume SvelteKitAuth is imported or defined somewhere above
// import { SvelteKitAuth } from 'some-auth-package';
// Your environment variable or secret key
const AUTH_SECRET = 'your_secret_here';
// Define your providers and other configurations for SvelteKitAuth
const providers = []; // Define your providers here
export const handle = async ({ request, resolve }) => {
// Place for your custom code BEFORE SvelteKitAuth logic
// For example, log the request or modify it
console.log('Handling request:', request.url.pathname);
// SvelteKitAuth integration
const authHandle = SvelteKitAuth({
trustHost: true,
providers: providers,
secret: AUTH_SECRET,
pages: { error: '/auth_error' }
});
// Call SvelteKitAuth's handle within your custom handle
const response = await authHandle({ request, resolve });
// Place for your custom code AFTER SvelteKitAuth logic
// For example, modify the response or log something
console.log('Request handled for:', request.url.pathname);
// Optionally modify the response
// response.headers['x-custom-response-header'] = 'your_value';
return response;
};
In this revised version, your handle
function first logs the request path, then proceeds to execute the SvelteKitAuth
logic by calling authHandle
, which is a wrapper around the SvelteKitAuth
configuration. Finally, after SvelteKitAuth
has processed the request, you can place any post-processing or additional logging.
This approach allows you to seamlessly integrate custom server-side logic with SvelteKitAuth
's authentication handling. You're free to adjust the pre- and post-processing parts according to your application's requirements, such as adding request validation, logging, custom headers, or any other server-side logic you need to execute on every request.TypeError: Cannot destructure property 'url' of 'event' as it is undefined.The error message you're encountering, "TypeError: Cannot destructure property 'url' of 'event' as it is undefined," suggests that when you're trying to destructure url
from event
, the event
object does not exist or is not being passed correctly in the context where you're attempting to destructure it.
This could be related to the way you're trying to access request.url.pathname
in the custom handle
function for SvelteKit. In SvelteKit's hook context, request
is an object provided to the handle
function, but it seems there might have been a misunderstanding in accessing its properties, especially if the destructuring was done incorrectly or in the wrong context.
Here's a corrected approach, ensuring that the request object is properly handled within the async handle
function:
export const handle = async ({ request, resolve }) => {
// Assuming SvelteKitAuth is correctly imported and set up
// Your custom code before SvelteKitAuth logic
console.log('Handling request:', request.url); // Correctly accessing the URL
// Initialize your SvelteKitAuth configuration
const response = await SvelteKitAuth({
// Your SvelteKitAuth config here
trustHost: true,
providers: providers, // Make sure providers is defined somewhere
secret: AUTH_SECRET, // Ensure AUTH_SECRET is defined
pages: { error: '/auth_error' }
})({ request, resolve }); // Note the immediate invocation with {request, resolve}
// Your custom code after SvelteKitAuth logic
// For example, log something or modify the response
console.log('Finished handling request:', request.url);
// Return the response object
return response;
};
Make sure of the following to avoid the TypeError
:
- Correct Context: Ensure you're destructuring
url
in the correct context whererequest
orevent
is defined and passed correctly. - Proper Access: Directly access
request.url
without destructuring if the structure ofrequest
might vary or if there's any uncertainty about its properties. - Check for Existence: Before destructuring or accessing properties, you might want to check if the
request
or its properties likeurl
exist.
If you were trying to destructure url
directly from request
and encountered this error, it means at some point, the request
object was not structured as expected. The corrected approach ensures you're accessing the request
object's properties directly within the scope where it's defined and passed to your function, minimizing the risk of encountering undefined
objects or properties.This seems to work ```/** @type {import('@sveltejs/kit').Handle} */
export const handle = async (request) => {
// console.log('Handling request:', request?.url?.pathname);
const authHandle = SvelteKitAuth({ trustHost: true, providers: providers, secret: AUTH_SECRET, pages: { error: '/auth_error' } });
const response = await authHandle(request); //console.log('Request handled for:', request?.url?.pathname);
// Optionally modify the response // response.headers['x-custom-response-header'] = 'your_value';
return response;
};```The revised version of your handle
function looks correct and should work well with SvelteKit's hooks system. By directly passing the request
object to both the SvelteKitAuth
function and logging mechanisms, you're ensuring that the function adheres to the expected structure of SvelteKit hooks. Here's a brief overview of what your code does:
Initialization of
SvelteKitAuth
: You're correctly setting upSvelteKitAuth
with your specified configuration options, such astrustHost
,providers
,secret
, and custom error page routing.Handling the Request: The
request
object is passed directly toSvelteKitAuth
, which should handle authentication based on the configuration you provided. This object includes details about the incoming request, such as headers, method, and URL.Optional Modifications and Logging: You've commented out the lines for logging and modifying the response, but these are good examples of how you can interact with the request and response objects within a SvelteKit hook. You can log request details or add/modify headers in the response before returning it.
Returning the Response: Finally, you return the response from
SvelteKitAuth
. This response can be modified further if needed before it's sent back to the client.
Just a couple of notes to ensure best practices and avoid potential issues:
Error Handling: Consider adding error handling around the
await authHandle(request)
call to catch any exceptions that might be thrown by the authentication process or your custom code. This can help in diagnosing issues and ensuring that your application can gracefully handle errors.Use of Optional Chaining (
?.
): Your commented-out console log statements use optional chaining to safely access properties of therequest
object. This is a good practice, especially when dealing with objects that might not always have the expected shape or when properties might be undefined in certain contexts.Environment Variables and Configurations: Ensure that
providers
andAUTH_SECRET
are correctly configured and imported or defined in your code. These are crucial for the authentication process to work as expected.
Your code snippet effectively demonstrates how to integrate custom authentication logic within a SvelteKit application while providing flexibility for additional request handling and response modifications.
