How To Recover a Deleted File that was Committed to Git and/or GitHub

So you deleted a file you shouldn't have and now you need to undo your mistake. We've all been there and lucky for us, with git it's fairly straightforward.

Build Log: Cutting Down My Blog Post Publishing Process

Friendcatchers are a good idea so let's make it easy to publish mine on the internet. How? By setting up a blogging system that makes it easy for me to hit publish. I have been self-hosting a ghost instance on Railway for a few months now and it's quite cheap at about $3 a month. So I'm thinking I'll just hook it up to a Next.js frontend and call it a day. The deadline for v1 of this project is 5 days from now. Let's see how well or badly I do. 20/02/2024 eod update I've been able to set up

Asynchronous JavaScript Headaches

Whenever I'm building something and I come across a scenario where I need to get something from my database I typically use the async await pattern but I've never really understood it. I typically use the async await thing and log my response, then I see some promise thing logged onto my response, then I introduce a try catch block. Sometimes that solves my problems, but today that didn't solve my problem. Typically I wrangle a mix of async functions to get it to work somehow but lord knows tha

Next.js Cache Gotcha

This one is a sneaky one, and caching is becoming synonymous with annoying. But that aside, here's the scenario. I'm working on the gift giving application. The use case is someone purchases a gift and that action triggers: * the generation of a voucher code. * the creation of a transaction object that stores the transaction information in the databases and associates the generated gift code with the transaction before sending the user an email with their gift code. Locally it works just fi

How to Create Unique Voucher Codes That Don't Collide

My first problem was how to generate the coupon codes. Initially, I wanted a way to put that functionality in the database. But because I want this working superfast and I don't have the luxury of figuring out all the quirks of getting it to work in the database, I opted for a server function. To generate the codes I'll be using the voucher-code-generator-js library from Voucherify. It's a cool little npm package and it works. I found it on the "How to generate unique coupon codes?" blog post.

How to Use the Supabase Service Role Secret Key in Next.js Routes

On my website,, I want users to be able to make purchases without them having a user account. The problem I ran into is that without user accounts, the server needs to be the one writing to the transactions table for the users on Supabase in order to bypass the Row Level Security. My issue was similar to this GitHub issue: Using service role secret key with supabase-js on the server #1284 Because I am using Next.js Route Handlers for my server-side functions, I needed

Building an Internal Dashboard for 47 Places

We're growing over at 47 places. When I launched the site back in February 2023 All the data was stored in a json file. To add a place I needed to jump into the file on vscode and edit it. The push the changes up to GitHub to trigger a redeploy of the site. It wasn't elegant but it worked. Since then the dashboard has evolved and this article covers what it took to get to the current V0.1 of the dashboard that we're using now. When Ly joined me, I taught her how to add places into the json fil

GitHub Field Day Nairobi 2022

The tagline for the event was: "An unconference for leaders of technical student communities". I applied because I thought it would be a really cool oportunity to meet other community leaders and get to hear their stories. A while ago, I would describe my efforts as trying to become a community leader or trying to understand the value of communities. But, a good friend of mine challenged my use of the word "trying". What she said went something like, "there's no trying, just doing or not doing.
