Web development/React & Next.jsQuestion

How do you organize a large Next.js app without creating a shared-folder mess?

Current situation Our App Router project now has billing, courses, exercises, and community features. Everything imports from one large components folder and changes are becoming risky. Code example Expected A structure where a product change stays inside one understandable boundary while shared UI remains reusable. What has worked for teams maintaining a Next.js application for several years?

Data & databases/SearchQuestion

When should PostgreSQL search use full-text, trigram, or both?

I need search across article titles and long bodies. Users also type incomplete words and make small spelling mistakes. Code example At roughly 300,000 rows this query is slowing down. How would you choose between a GIN full text index and pg trgm ?

Code example

React hydration fails only when I format a date in production

What checks belong in a secure image-upload endpoint?

I am adding screenshots to community posts. The browser provides a MIME type, but I know that value can be forged. Current checks 4 MB maximum PNG, JPEG, WebP, or GIF Random generated filename What should happen before the file reaches object storage?

Python & automation/Async PythonQuestion

Why is asyncio.gather slower than sequential requests in this script?

I expected these requests to run concurrently, but the async version is slightly slower. Code example There are about 80 URLs from the same API.

Data & databases/AnalyticsQuestion

How can I calculate monthly retention cohorts in PostgreSQL?

I have an accounts table with created at and an events table with account id and occurred at . I need a matrix where each row is a signup month and columns show the percentage active in months 0–6. The event table has roughly 40 million rows. A query shape and indexing advice would both help.

Web development/HTML & accessibilityQuestion

Where should focus move after a server-validated form fails?

The form returns several validation errors after submit. Each input has an inline error, but keyboard and screen reader users are not told that submission failed. Code example Should focus move to the first invalid field or to an error summary?

Tools & deployment/Docker & deploymentQuestion

Docker environment variable exists during build but disappears at runtime

The image builds successfully and prints the variable in one build step, but the Node process sees undefined after deployment. Code example I am currently considering copying the value into the image with ENV . Is that safe for a server secret?

Backend & APIs/API designQuestion

How should I model an API result so every error case is exhaustively handled?

My current response type uses several optional properties, so impossible states compile. Code example I want the UI to require separate handling for success, validation failure, authentication failure, and an unexpected server error.

Career & community/Open sourceQuestion

What made your first open-source contribution approachable?

I can read issues and run projects locally, but I keep postponing my first contribution because the repositories feel large. What I have tried Read contribution guides Filtered for good first issue Reproduced two documentation bugs How do maintainers prefer a new contributor to make contact before opening a pull request?

Tools & deployment/Git & collaborationQuestion

Should I rebase a feature branch after three teammates have pulled it?

We have a long lived feature branch with commits from three people. Main has moved forward and the branch now has conflicts. I normally rebase my private branches, but force pushing this one seems risky. Is merging main into the feature branch the safer option here, or is there a clean team rebase workflow?
