JIT vs full mode is one of the most common decision points we see. Here is the honest breakdown.
The short version#
JIT scans and emits used classes; full emits everything.
Point by point#
| Aspect | Analysis |
|---|---|
| Size | JIT: 5–20 KB; full: ~6 MB |
| Use case | Production always JIT; full for CDN prototyping |
| Dynamic classes | JIT needs safelists for runtime names; full needs none |
| Switching | Set content globs → JIT activates automatically |
Bottom line#
Pick based on your constraint, not ideology — and remember the comparison pages link to hands-on recipes so you can verify the claim in your own project within minutes.
