Have you dealt with API security in static sites?

fredlag — Tue, 10 Feb 2026 13:00:00 +0000

A few years ago, I built a static website to showcase my portfolio and added a weather API integration (because I love cycling and hate getting wet 🚴‍♂️).

Everything worked great... until my cybersecurity training revealed something alarming: my API token was publicly accessible in my JavaScript code. 😱

The Problem

Static sites can't keep secrets. Any API key in your client-side code is visible to anyone who opens the developer console.

I needed a solution. Fast.

My Solution Journey

I explored three different approaches:

❌ Custom backend - Didn't want extra hosting costs
❌ Netlify Functions - Required hosting entire site on Netlify
✅ WordPress REST API - Already had it running on my server!

The Surprising Winner

Turns out, WordPress isn't just for blogging. It can act as a secure API proxy for your static sites, keeping your API keys safe on the server side.

And the implementation? Surprisingly simple.

What I Learned

Through this journey, I discovered:

Why static sites fundamentally can't hide secrets
How to use WordPress as a lightweight backend
Adding caching and rate limiting for optimization
When to consider alternative solutions

Hello everyone! It’s summer holiday time here, and if you’re lucky enough to be traveling or heading to the beach, there’s no need to stop coding. I’ve set up my coding environment on my Android tablet, so I can code from anywhere.
Let’s take a look at how I configured it.

Succed in migration code base from svn to git

fredlag — Fri, 16 Feb 2024 11:00:00 +0000

Hello,

For the first post of the year, I'd like to share my feedback on migrating a large code base from SVN to Git. A while back, I asked a question about this migration migration.

Despite not receiving many comments, I'm excited to share my recommendations now:

No Technical Challenges:
I didn't face any significant technical challenges, except in cases where the initial SVN project didn't adhere to standard recommendations. In such instances, it's essential to modify the SVN project to ensure it aligns with standard practices.

Communication and Planning are Key:

1. Team Training:
Conduct workshops or training sessions to familiarize the team with Git concepts. Providing resources and documentation to support the learning process is crucial.

2. Continuous Communication:
Maintain an open line of communication throughout the migration process. Address concerns and feedback promptly to keep the team engaged and informed.

3. Feedback Loops:
Establish feedback loops to gather insights during and after the migration. Iterate on processes based on team feedback to enhance collaboration and efficiency.

By focusing on effective communication, thorough planning, and incorporating feedback loops, the migration from SVN to Git can be smooth and successful.

I hope these insights are helpful for anyone undertaking a similar migration journey.

Happy coding!
