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.

JSON

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

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.

Regex

Common regex mistakes that waste debugging time

Avoid greedy matches, missing anchors, escaping mistakes, and catastrophic backtracking when testing regular expressions for real code.

Encoding

Base64 encoding pitfalls developers run into

Learn why Base64 output breaks because of padding, Unicode strings, URL-safe alphabets, and data URL prefixes.

URLs

URL encoding bugs in API requests

Fix common URL encoding mistakes in query strings, callback URLs, OAuth redirects, and nested API parameters.

Security

JWT debugging checklist for auth failures

A practical checklist for checking JWT claims, expiration, audiences, issuers, algorithms, and signature verification.

Data

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

YAML indentation errors in CI and config files

Understand why YAML config breaks from indentation, tabs, lists, multiline strings, and accidental type coercion.

XML

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.

Time

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

HTML escaping basics for safer output

Learn when to escape HTML entities, how XSS happens through untrusted text, and why encoding context matters.

SEO

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.

SEO

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.

Developer Workflow

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

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.

Developer Workflow

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.

SEO

Meta tags and Open Graph checklist before publishing

Check titles, descriptions, canonicals, Open Graph images, Twitter cards, and structured data before shipping a page.
