This plugin is for Babel 6. If you need to support Babel 5 use the v0.2.x branch.
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.
Given the .babelrc
{
"plugins": [["filter-imports", {
"debugging-tools": [ "warn" ]
}]]
}
the module
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
import { warn } from 'debugging-tools';
function join(args, sep) {
if (arguments.length > 2) {
}
return args.join(sep);
}

If you need to support Babel 5 use the [v0.2.x](https://github.com/ember-cli/babel-plugin-filter-imports/tree/v0.2.x) branch.* 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. ## Example Given the `.babelrc` ```json { "plugins": [["filter-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 import { warn } from 'debugging-tools'; function join(args, sep) { if (arguments.length > 2) { } return args.join(sep); } ``` ## Configuration - `options` `[Object]`: An object whose keys are names of modules. - `options[moduleName]` `[String]`: An array of names of imports from `moduleName` to be removed. You can include `'default'` for default export and `'*'` for a namespace export.
