I built a deterministic OpenAPI differ because I got tired of LLMs writing changelogs that sounded confident and were completely wrong. The tool takes a base spec and a new spec, walks the paths, schemas, and parameters, and emits a…
This challenge teaches the absolute basics of netcat (nc): connecting to a remote host and port, reading what the service sends back, and responding correctly to get the flag — the very first building block of any network/pwn-oriented CTF. The…
Essa flexibilidade não torna GraphQL automaticamente mais rápido, menor ou mais simples que REST. Ela desloca parte do trabalho para o schema e para os resolvers: o cliente escolhe os campos, mas o servidor continua responsável por autorização, validação, limites…
Most frontend apps talk to a backend that already has an OpenAPI description. Yet a lot of us still write the types by hand, or copy them from Swagger UI, and then watch them slowly drift away from what the…
A Raspberry Pi is the most common way people first meet FRP. You've got Home Assistant, a small web dashboard, maybe a Minecraft server for the kids — all sitting on the Pi, all needing to be reachable from outside the…
I've been using ts-rest for a while, and I genuinely liked it. Contract-first APIs, end-to-end type safety, OpenAPI support, and a clean developer experience. It had pretty much everything I needed. But over time, I started having concerns about its…
Building APIs is a core part of backend development, and REST has traditionally been the go-to choice for many applications. However, as applications grow more complex, clients often need data from multiple resources without making several separate requests. GraphQL provides…
Click Export HAR (sanitized) in the Network panel toolbar and save the file as app.har. The sanitized export leaves out Cookie, Set-Cookie and Authorization headers. Paste the file into Swagger Editor or run openapi-generator-cli validate -i openapi.yaml. Then…
Teams pick an API client out of habit and then spend months paying for a model that never matched how they actually work. The split between the common choices is not the pretty UI. It is where the contract lives:…
Every few months a team decides to rebuild its internal APIs on gRPC. Ask why, and the answer is usually a benchmark graph from a blog post. Ask what problem it solves for them, and the room goes quiet. gRPC…
Schemas, federation, protobuf, and contract-first service stacks.
