# Minifier
EcmaScript minifier for the SWC project. This is basically a port of terser.
# Note
Currently name mangler is very simple. To focus on creating a MVP, I (kdy1) will use simple logic for name mangler and implement the content-aware name mangler after publishing first non-beta version.
## Debugging tips
If the output contains variables named `e`, `t`, `n` it typically means the original library is published in a minified form and the input contains `eval`.
The current swc name mangler does not do anything if `eval` is used.
# Profiling the minifier
From mac os x, run
```
./scripts/instrument/all.sh path/to/input/dir
```
