Containers on a developer laptop and containers in production are two fundamentally different things. This Docker checklist covers every mandatory category: security hardening, performance limits, storage protection, and repeatable deployment procedures, with concrete commands for each item.

A pure function always returns the same result for the same arguments and changes nothing outside its own return value. This principle of referential transparency makes PHP code predictable, easy to test and parallelizable, without any extra framework or new language syntax.

A cron job that runs at night normally vanishes without a trace for Prometheus: no running process means no scrapable HTTP endpoint. The Node Exporter textfile collector solves that problem by reading simple .prom files from the filesystem that a Bash script writes itself, making cron job duration, success, or failure queryable in Prometheus without any extra service.

Writing test data as loosely typed object literals invites silent decay the moment the underlying domain type changes and gains a new required field. Type-safe factory functions with Partial-T and sensible defaults centralize test data in one place, force synchronization with the real interface, and keep Vitest suites maintainable and consistent across hundreds of test files.

Committing PSD files, videos, or archives straight into Git needlessly bloats repository size and clone time for the whole team, because Git's delta compression barely works on binary data. Git LFS replaces these files with lightweight pointers and stores the actual content externally, without changing the familiar commit and push workflow at all.

Order confirmations, shipping notifications, and password reset emails almost always share the same basic structure. MJML provides the reliable, table-based layout layer for this, while Tailwind utility classes deliver the visual design, so transactional emails stay maintainable instead of consisting of scattered copies.

Magento 2 ships with no subscription engine out of the box, subscription products have to be developed as a standalone module.

Maintaining TypeScript types manually alongside objects and constants eventually produces drift between code and type definition. The keyof and typeof operators derive types directly from existing values and interfaces, so object keys, configuration values and literal options stay automatically in sync while the compiler reliably rejects typos in property access.

State explosion is the most common maintainability problem in growing Vue projects: components accumulate reactive variables, watchers, and local state until they become impossible to understand. The way out is to minimize state, derive state from props, and use reactivity only where it is actually needed.

GDPR requires that a notifiable personal data breach be reported to the competent supervisory authority within 72 hours of becoming aware of it. That deadline sounds clear in theory, but quickly turns into a real problem when a company has to scramble an IT team together on a weekend just to figure out which data was affected and to what extent. Defining the notification process ahead of time, and building the technical foundation for a fast scope assessment, turns a crisis into a workable checklist.
