Error Handling
All Nuxt.js topics∙ Topic
Error Handling explains Nuxt rendering boundary specialized for Error Handling with focus terms: error, handling, reference UE7EF55. You will learn the rule, failure mode, verification plan, and production evidence for this Nuxt.js topic.
Syntax
defineRouteRules({ prerender: true })Example
// Topic: Error Handling
const rendering = { ssr: true, hybrid: true };
console.log(rendering.ssr && rendering.hybrid ? 'hybrid ready' : 'check rules');
// Expected Output: hybrid readyBest Practices
- 1Define what Error Handling owns across pages, layouts, composables, server routes, state, and deployment. Use the focus terms (error, handling, reference UE7EF55) to keep this lesson tied to its exact Nuxt.js topic.
- 2Document Nuxt rendering boundary specialized for Error Handling with focus terms: error, handling, reference UE7EF55 in the smallest useful page, layout, composable, store, server route, or deployment step.
- 3Represent every loading, success, denied, stale, and failure state that Error Handling can expose.
- 4Test the primary path, one SSR/client boundary, and one failure case for Error Handling. Include a check for these focus terms: error, handling, reference UE7EF55.
- 5Use TTFB, LCP, freshness, and hydration errors for Error Handling tracked for error, handling, reference UE7EF55 to guide improvements.
- 6Start with clear requirements and one minimal working example.
- 7Use meaningful names that explain business intent.
- 8Keep examples small enough to debug line by line.
- 9Validate input at every trust boundary.
- 10Handle errors explicitly and preserve useful context.
- 11Prefer simple control flow over deeply nested logic.
- 12Separate domain logic from I/O and framework code.
- 13Write tests for normal, boundary, and failure cases.
- 14Review security assumptions before production use.
- 15Measure performance before optimizing.
- 16Document non-obvious decisions close to the code or in project notes.
- 17Use official documentation when behavior is version-specific.
- 18Keep dependencies current and remove unused code.
- 19Avoid hardcoded secrets, credentials, and environment-specific paths.
- 20Log operational events without exposing sensitive data.
- 21Design examples so learners can safely modify and rerun them.
- 22Prefer maintainability over short-term cleverness.
