babel-plugin-remove-dts-export

For now official Babel typescript plugin has a Babel#6065 issue that forbids re-exporting types from d.ts files. It can cause a lot of problems connected with using types from d.ts files freely. This plugin is designed to be a kind of patch for this issue.

With default settings it checks every import in file processing right now and checks if the source is d.ts file. If it's true, it remembers all specifiers you imported from d.ts file and removes them from all exports defined in current file. Import declaration is removed as well.

Also you can set up a configuration. You can disable default checks for source to be a d.ts file (to avoid penalty of synchronous file system reading) and set specific sources or even custom specifiers for source you want to be erased.

Installation

$ npm install --save-dev babel-plugin-remove-dts-export

Configuration

Default behavior (checking every imports to be a d.ts file)(original, compiled):

{
  "plugins": [
    "babel-plugin-remove-dts-export"
  ]
}

Remove import declaration and all imported specifiers from all exports declared in a file (original, compiled):

{
  "plugins": [
    ["babel-plugin-remove-dts-export", {
      "sources": [
        "path/to/declaration/from/cwd.d.ts",
        "path/to/declaration/from/cwd2.d.ts"
      ]
    }]
  ]
}

Remove only specific specifiers from all exports declared in a file (original, compiled):

{
  "plugins": [
    ["babel-plugin-remove-dts-export", {
      "specifiersBySource": {
        "path/to/declaration/from/cwd.ts": ["A", "B"]
      }
    }]
  ]
}

Disable checking all imports to be d.ts files (following configuration will disable plugin completely!):

{
  "plugins": [
    ["babel-plugin-remove-dts-export", {
      "disableDefaultBehavior": true
    }]
  ]
}
