Import Cost VSCode Extension

This extension will display inline in the editor the size of the imported package. The extension utilizes webpack with babili-webpack-plugin in order to detect the imported size.

Features

Calculates the size of imports and requires. Currently supports:

• Default importing: import Func from 'utils';
• Entire content importing: import * as Utils from 'utils';
• Selective importing: import {Func} from 'utils';
• Selective importing with alias: import {orig as alias} from 'utils';
• Submodule importing: import Func from 'utils/Func';
• Require: const Func = require('utils').Func;
• Supports both Javascript and Typescript

Configuration

The following properties are configurable:

  // Upper size limit, in KB, that will count a package as a small package
  "importCost.smallPackageSize": 50,

  // Upper size limit, in KB, that will count a package as a medium package
  "importCost.mediumPackageSize": 100,

  // Decoration color for small packages
  "importCost.smallPackageColor": "#7cc36e",

  // Decoration color for medium packages
  "importCost.mediumPackageColor": "#7cc36e",

  // Decoration color for large packages
  "importCost.largePackageColor": "#d44e40",

  // File extensions to be parsed by the Typescript parser
  "importCost.typescriptExtensions": [
    "\\.tsx?$"
  ],

  // File extensions to be parsed by the Javascript parser
  "importCost.javascriptExtensions": [
    "\\.jsx?$"
  ]

Any package size above the mediumPackageSize limit will be considered large.

Known Issues

• Importing two libraries with a common dependency will show the size of both libraries isolated from each other, even if the common library needs to be imported only once.
