Sublime Plugin Import Cost

Sublime Text 3 plugin that shows the import costs of imported JS modules.

Install

The best way is to install the plugin via Package Control, just search for import cost. Besides that, you also have to have node installed, as well as the npm package import-cost:

npm i -g import-cost

Config

To change config options, open the menu Sublime Text > Preferences > Package Settings > Import Cost after installing the plugin. The following options are available:

{
  // Check import costs of npm modules when saving a file
  "check_on_save": true,

  // Check import costs when opening a file
  "check_on_open": true,

  // File sizes for differnt warning levels in kb
  "min_size_warning": 40,
  "min_size_error": 100,

  // Path to node binary
  "node_path": "/usr/local/bin/node",

  // File extensions that should be considered
  "extensions": [ "js", "jsx" ],

  // Show gzip size as well
  "show_gzip": false
}

Shoutouts

To wix for the awesome npm package, and to @princemaple for contributing to make this plugin work on Windows as well 🎉

Todos

• Add basic menus and settings
• Add "show gzip" option
• Make plugin available through plugin manager
• Make plugin smarter to always find correct node_modules folder, no matter what folder is currently open in sublime
• Add caching on python level (import-cost has caching itself, but we still have the expensive node bridge thing going on, which is very avoidable)
• Windows support
