REST vs GraphQL: How to Choose the Right API Style for Your Project

·1 views

REST and GraphQL are two widely used API approaches, each with distinct trade-offs depending on the use case. REST organises data around fixed endpoints and HTTP methods, making it simple to implement, cache, and version, but it can lead to over-fetching or multiple round-trips for related data. GraphQL lets clients request exactly the fields they need in a single query, which benefits mobile apps on variable networks, though it introduces added complexity in setup, caching, and query management. Many teams adopt a hybrid approach, using REST for public-facing APIs and GraphQL internally to reduce frontend round-trips. The best choice depends on team familiarity, client needs, and whether the API is intended for public or controlled consumption.

Developer Shares Key Bash Lessons: Regex, Loops, and Task Automation

A developer has wrapped up a month-long deep dive into Bash scripting, documenting their progress in a three-part series on DEV Community. After mastering expansions and syntax, they moved on to regex, along with command-line tools like grep, sed, and awk, which proved valuable for automation. They also explored conditionals, loops, arrays, and shell options, building several mini projects to apply their learning. All practice scripts have been shared publicly on a GitHub repository for others to reference. The developer noted that the experience changed how they interact with their own machine, replacing many manual tasks with automated solutions.

Cybersecurity Beginner Builds Wazuh SIEM With Sysmon and Atomic Red Team Tests

Christopher Bontempi, a cybersecurity career-changer, documented his first hands-on SIEM project by deploying Wazuh and Sysmon on a Windows endpoint called ART Workstation. He used Atomic Red Team's safe attack simulations to generate controlled activity and verify whether the SIEM could detect it. Two of his three tests produced matching alerts in both Sysmon and Wazuh, confirming end-to-end log forwarding. A third test revealed a detection gap — Sysmon captured the activity locally, but no corresponding Wazuh alert was found — highlighting that logging tools must be actively validated, not assumed to be working. The project also surfaced practical lessons around using structured SIEM fields for searches and accounting for UTC timestamp differences between Sysmon and local system time.

How Race Conditions Threaten Backend Systems and Ways to Fix Them in Express.js

Race conditions occur when multiple simultaneous requests access and modify the same shared data, producing unpredictable or incorrect outcomes that depend on execution timing. Common real-world consequences include oversold inventory, duplicate financial transactions, incorrect account balances, and conflicting profile updates. In Express.js, asynchronous operations such as database queries and API calls make applications especially vulnerable, since checks and writes can interleave across concurrent requests. Developers can mitigate these issues using database transactions, mutex locks, or idempotency keys, each carrying trade-offs in complexity, latency, or throughput. Choosing the right strategy depends on the specific operation, making race condition awareness a critical skill for backend engineers.

Bash Series Part 2: A Developer's Guide to Shell Expansions Explained

A developer continuing a month-long Bash learning series has documented key concepts around shell expansions and special parameters. The article covers how Bash interprets scripts line by line without halting on errors unless flags like set -euo pipefail are explicitly set. It walks through several expansion types including brace, tilde, parameter, command substitution, and arithmetic expansion, with practical code examples for each. The author notes limitations such as Bash's lack of native floating-point arithmetic, requiring the bc utility for such calculations. The series is set to continue with topics including regex and tools like grep, sed, and awk.
