A Timer App you can fully control with keyboard shortcuts

Ko1103 — Mon, 27 Oct 2025 05:54:30 +0000

Many people use timers to boost their productivity — and I was one of them.

But I always ran into a few small frustrations:

I kept setting the same durations manually every time.
Mouse interactions felt too slow and distracting.

So, I built an app that solves these problems.

⏱️ Preset durations

You can simply pick from commonly used time intervals — no need to type anything.

⌨️ Fully keyboard-driven

Show, hide, start, stop — everything can be controlled through shortcuts.

It’s a minimal timer app focused on speed and simplicity.
Give it a try and see how it fits into your workflow!

Building a gRPC Server with NestJS and Buf: A Comprehensive Showcase

Ko1103 — Mon, 06 May 2024 14:39:11 +0000

Introduction

If you're familiar with NestJS and gRPC, you may have already referred to the official documentation on implementing gRPC in NestJS. While Protoc is a standard tool, as you delve deeper into customization, its complexity increases.

This is where Buf comes in. Buf offers a simpler alternative to Protoc for generating SDKs, documentation, and more. Despite its simplicity, I noticed a lack of sample projects or showcases integrating Buf with NestJS.

Therefore, I took it upon myself to create one.

Overview of repository

This repository (https://github.com/Ko1103/nestjs-buf-example) is a NestJS and Buf usage example for protobuf server implementation.

Installation and Setup

Requirements

docker & docker compose cli
Node.js v18

Please note that I developed this project using an M1 Mac.

To get started, clone repository.

git clone git@github.com:Ko1103/nestjs-buf-example.git

Next, install the node_modules

npm ci

Generate TypeScript SDK from protobuf files

npm run proto:gen

Finally bring up docker container.

docker compose app

Try accessing gRPC via http:localhost/5000.

Conclusion

With this repository, you now have the ability to create new gRPC projects with NestJS using Buf. However, I'm concerned that the TypeScript SDK generated into src/proto may not be optimal. Please feel free to share any alternative options or ideas you may have regarding this.

Thank you for reading until the end.
