**Description:** Note: Preserving native names is a hack, but it's used by `terser` and it's the only way to preserve the name of `class AbortSignal` while mangling without `keep_classnames: true`. We can special case `AbortSignal`, but let's just follow `terser`. **Related issue:** - https://github.com/vercel/next.js/pull/57904 |

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
