import-cost.nvim

Display javascript import costs inside neovim, powered by import-cost.

Note

Due to GitHub's historic unreliability, active development is hosted on Forgejo. GitHub is maintained as a read-only mirror. See :help import-cost-migration to optionally update your plugin source configuration.

Installation

With vim.pack (Neovim 0.12+):

vim.pack.add({
  'https://git.barrettruth.com/barrettruth/import-cost.nvim',
})

Or via luarocks:

luarocks install import-cost.nvim

Dependencies are installed automatically on first use.

Quick Start

Open a JavaScript, TypeScript, or Svelte file with import statements and wait for inline virtual text costs to appear.

If the defaults need changing, set vim.g.import_cost before the plugin loads.

vim.g.import_cost = {
  package_manager = 'yarn',
  format = {
    virtual_text = '%s',
  },
  highlight = 'Comment',
}
