- **`terser` is API/CLI compatible with `uglify-es` and `uglify-js@3`.**
Why choose terser?
------------------
`uglify-es` is no longer maintained and `uglify-js` does not support ES6+.

### Build Tools and Adaptors using Terser
https://www.npmjs.com/browse/depended/terser
### Replacing `uglify-es` with `terser` in a project using `yarn`
A number of JS bundlers and uglify wrappers are still using buggy versions
of `uglify-es` and have not yet upgraded to `terser`. If you are using `yarn`
you can add the following alias to your project's `package.json` file:
```js
"resolutions": {
"uglify-es": "npm:terser"
}
```
to use `terser` instead of `uglify-es` in all deeply nested dependencies
without changing any code.
Note: for this change to take effect you must run the following commands
to remove the existing `yarn` lock file and reinstall all packages:
```
$ rm -rf node_modules yarn.lock
$ yarn
```
