Nginx config for SvelteKit SPA

February 6, 2025 / abhijit / 0 Comments

For creating a SvelteKit SPA app, we first need to set up SvelteKit to have all the pages pre-rendered. For this, for every +page.svelte we need to add a +page.server.ts or a +page.server.js with the following –

export const prerender = true;
export const ssr = true;

This will create the corresponding pages for each route. For example, if we have a URL like example.com/about, we will have an about.html page getting created.

However, putting the build folder directly under a simple nginx config doesn’t work. Since the URL does not have an .html extension, even if those pages are there, nginx doesn’t show them.

Install code-server (VS Code for web) on Linux with Nginx

January 2, 2025 / abhijit

VS Code is the code editor of choice for many. However, when we want to do quick edits on some files on a remote server, and there is no access to VS Code, it becomes a bit of a hassle.

Also, sometimes VS Code is not accessible on a particular system and we might still want to be able to access local files and folders using VS Code.

This is where code-server is invaluable.

Powershell – find alias or function in profile by pattern

August 9, 2024 / abhijit

Since I have lots of aliases and functions in my profile, frequently I need to search them by some pattern.

This Powershell function lets me do just that.

function ff {
  param(
    [string]$Pattern
  )

  # Define the path to the PowerShell profile
  $profilePath = $PROFILE

  # Check if the profile exists
  if (-not (Test-Path $profilePath)) {
    Write-Host "Profile script does not exist at $profilePath"
    return
  }

  # Define the patterns to search for aliases and functions
  $patterns = "Set-Alias.*$Pattern", "New-Alias.*$Pattern", "function.*$Pattern"

  # Search the profile for the specified pattern
  # Select-String -Path $profilePath -Pattern $patterns
  Select-String -Path $profilePath $patterns
}

Now, all I need to do is type this to find the matching line and the actual function in my profile.

> ff <pattern>

Ruby OpenSSL::SSL::SSLError – SSL_connect returned=1 errno=0 unsafe legacy renegotiation disabled

June 18, 2024 / abhijit

So, all of a sudden, one of our servers, while trying to connect to another, started giving this cryptic error –

OpenSSL::SSL::SSLError - SSL_connect returned=1 errno=0 unsafe legacy renegotiation disabled

These kind of errors are usually dependent on some system updates. But the error seemed to be coming from the target server. After a bit of searching around, this article gave the most understandable information.

From that article –

This “unsafe legacy renegotiation disabled” error happens when connecting to outdated endpoints that do not support RFC 5746 secure renegotiation. Ideally, the endpoints causing these errors should be upgraded for security reasons.

In the same article, they mention that it should be possible to remove this security check, but the solutions mentioned there didn’t work.

How to require multiple files in irb from command line

March 16, 2024 / abhijit

Recently, I had the need to run Ruby’s irb with multiple files already loaded.

After a bit of trial and error I came up with this which worked perfectly!

irb -r ./file1.rb -r ./dir/file2.rb

The files get loaded in order so if there are any dependencies in file2.rb on something in file1.rb, that works correctly.

Upgrading Wallabag (again!)

March 11, 2024 / abhijit

So, I upgraded my server to the latest Ubuntu release and Wallabag broke. I remember I had a tough time upgrading Wallabag. So this time, I decided to run it as a Docker container to avoid issues.

Unfortunately, this also had a few challenges!

Most of the stuff on my server run using flat files or SQLite databases, so I referred to the official Wallabag docs for running it on Docker. It gave the docker run command, but I wanted it as a docker-compose.yml file instead.

Do not take life too seriously. You will never get out of it alive.

Disable browser caching in Ruby Roda app

January 20, 2024 / abhijit

Recently, writing a plain Roda app, I was facing a caching problem. I had a list and a detail page and whenever there was a list item clicked on I was using the flash plugin to maintain the item selected and highlighting the item when the list page was loaded.

However, on navigating back via the browser button, the cached page was showing up and the highlight would be on the previous selected item or not there at all.

fzf – error when pressing Ctrl+R

November 11, 2023 / abhijit

I’ve become a big fan of fzf since I discovered it.

However, after a recent upgrade, when I pressed Ctrl+R, I got the following error –

unknown option: --scheme=history

After some searching, found the following solution.

Remove fzf from /usr/bin/ and relink it.

Run these two commands in order –

sudo rm /usr/bin/fzf
sudo ln -s ~/.fzf/bin/fzf /usr/bin/fzf
