A babel transform for filtering out imports
npm install babel-plugin-filter-imports


This babel plugin is used to removed references to imports within a module. This can be useful for removing debugging statements when doing a production build of your code. It is often used in conjunction with other tools like Uglify that perform dead code elimination.
``sh`
$ yarn add --dev babel-plugin-filter-imports
This plugin is for Babel 7. If you need to support:
- Babel 6 use the babel6 branch
- Babel 5 use the v0.2.x branch
Given the .babelrc
`json`
{
"plugins": [["filter-imports", {
"imports": {
"debugging-tools": [ "warn" ]
}
}]]
}
the module
`js
import { warn } from 'debugging-tools';
function join(args, sep) {
if (arguments.length > 2) {
warn("join expects at most 2 arguments");
}
return args.join(sep);
}
`
will be transformed to
`js`
function join(args, sep) {
if (arguments.length > 2) {
}
return args.join(sep);
}
