Bundle Size
JS bundles exceeding size budgets.
One of 122 modules in the GateTest scan suite. Catches the issue before it reaches code review, and on paid tiers opens a pull request with the fix already written.
main.js 412 KB gzip — budget is 200 KB
Why we catch it
Catches the supply-chain takeovers, container exploits, and CI/CD foot-guns.
The Bundle Size module sits in this category alongside 6 related modules. Together they form one of the layers of a GateTest scan — checks fire in parallel, findings cluster by root cause, and on paid tiers the AI auto-fix loop reads each finding, writes the fix, validates against the scanner, and opens a PR.
How GateTest covers bundle size
- Runs on every Full scan and above. Full ($99), Scan + Fix ($199) and Forensic ($399) — every repository tier except Quick ($29), which runs only 4 modules. No additional configuration.
- Free CLI.
npm i -g @gatetest/cli && gatetest --module bundleSizeagainst any local repo. No paywall on the scanning itself. - AI auto-fix PR. Scan + Fix tier opens a pull request with the fix, a regression test, and a pair-review by a second AI reviewer. Forensic Scan tier adds per-finding diagnosis and cross-finding attack-chain correlation.
- Honest confidence rating. Findings come with high / medium / low confidence so noisy patterns don't block the gate. The confidence-calibrator trainer reads customer suppressions and tightens rules over time.
