Developer articles
Practical notes from building and debugging developer tools: broken payloads, confusing encodings, auth tokens, SEO checks, and the small workflow problems that slow down real engineering work.
How to debug malformed JSON without guessing
A practical workflow for finding broken JSON, fixing common syntax errors, and validating payloads before they reach an API or config parser.
JSON Formatter vs JSON Validator: when to use each
Understand the difference between formatting and validation so you can read JSON clearly without mistaking pretty output for correct data.
Common regex mistakes that waste debugging time
Avoid greedy matches, missing anchors, escaping mistakes, and catastrophic backtracking when testing regular expressions for real code.
Base64 encoding pitfalls developers run into
Learn why Base64 output breaks because of padding, Unicode strings, URL-safe alphabets, and data URL prefixes.
URL encoding bugs in API requests
Fix common URL encoding mistakes in query strings, callback URLs, OAuth redirects, and nested API parameters.
JWT debugging checklist for auth failures
A practical checklist for checking JWT claims, expiration, audiences, issuers, algorithms, and signature verification.
CSV to JSON conversion mistakes and how to avoid them
Avoid broken CSV imports by handling delimiters, quotes, empty fields, headers, and type coercion before converting to JSON.
YAML indentation errors in CI and config files
Understand why YAML config breaks from indentation, tabs, lists, multiline strings, and accidental type coercion.
How to validate XML in CI/CD workflows
Add XML formatting and validation checks to CI so broken feeds, config files, and integration payloads fail before deployment.
Timestamp and timezone bugs developers keep repeating
Debug Unix timestamps, local time, UTC offsets, DST boundaries, and off-by-one-day errors in apps and APIs.
HTML escaping basics for safer output
Learn when to escape HTML entities, how XSS happens through untrusted text, and why encoding context matters.
Robots.txt validation guide for developer sites
Check robots.txt rules, sitemap references, crawler directives, and accidental disallow patterns before search engines crawl your site.
Sitemap priority for large developer tool sites
Learn how to prioritize important tool pages, exclude weak pages, and keep sitemap signals aligned with content quality.
Why trivial developer tasks take longer than expected
Small tasks like formatting JSON, decoding tokens, and escaping strings waste time because hidden assumptions matter.
Privacy model for browser-based developer tools
Understand when browser tools keep data local, when server-backed tools are needed, and how to avoid pasting sensitive secrets.
Best developer browser tools for everyday debugging
A practical list of browser-based tools developers use for JSON, regex, JWTs, URLs, timestamps, diffs, and web metadata.
Meta tags and Open Graph checklist before publishing
Check titles, descriptions, canonicals, Open Graph images, Twitter cards, and structured data before shipping a page.
