About


Terser is a minifier which was born as a fork of the now unmaintained harmony branch of the Uglifyjs project.
Now it's grown into its own thing and is capable of minifying modern JavaScript. I aim to support what's on stage 4, but on some occasions I'll add support for ES features that are still at stage 3.
There is good support for reading and generating source maps provided by the @jridgewell/source-map library.
The codebase uses a custom EcmaScript AST, and can read and output ESTree formatted ASTs like the ones generated by acorn.
