Performance

Performance

Run the local benchmark with:

npm run benchmark

The benchmark generates temporary locale files and a Vue source file, then measures:

• config loading
• locale loading and flattening
• identical translation checks
• placeholder checks
• hardcoded string checks

The default fixture uses 3,000 generated key groups per locale.

Override it with:

I18N_SMELL_BENCH_KEYS=10000 npm run benchmark

This is a repeatable development benchmark, not a hard CI threshold. CI machines vary enough that performance assertions should be introduced only after collecting baseline data across multiple runs.

What To Watch

• Avoid repeatedly reading the same locale file.
• Keep glob expansion scoped to configured source roots.
• Prefer parser-backed source scanning over broad regular expressions when behavior becomes complex.
• Compare issue ids and stable fingerprints when changing report output.
