Context

TypeScript development often involves switching between the editor and terminal to run type checks. As someone who regularly works with TypeScript, I've experienced this pain point firsthand. While I explored solutions like tsc.nvim, they didn't quite fit my needs. Drawing on my experience creating my-note.nvim and hurl.nvim, I decided to develop a new tool: typecheck.nvim.

What is typecheck.nvim?

typecheck.nvim is a Neovim plugin specifically designed to streamline TypeScript development. It provides real-time type checking, integrating effortlessly with Neovim's quickfix window, which allows for quick navigation and fixing of type errors within your TypeScript projects.

Features

• Asynchronous type checking: Run TypeScript compiler (tsc) checks without blocking the Neovim UI.

• Integration with quickfix or trouble.nvim window: View and navigate TypeScript errors and warnings directly within Neovim.

Installation

To integrate typecheck.nvim into your workflow, include the following in your plugin manager's configuration:

return {
  "jellydn/typecheck.nvim",
  dependencies = { "folke/trouble.nvim", dependencies = { "nvim-tree/nvim-web-devicons" } },
  ft = { "javascript", "javascriptreact", "json", "jsonc", "typescript", "typescriptreact" },
  opts = {
    debug = true,
    mode = "trouble", -- "quickfix" | "trouble"
  },
  keys = {
    {
      "<leader>ck",
      "<cmd>Typecheck<cr>",
      desc = "Run Type Check",
    },
  }
}

Demo

Simply run :Typecheck to initiate type checking. The quickfix window pops up to display any errors or warnings, streamlining the error-handling process.

Integration with trouble.nvim

For those who prefer trouble.nvim like me :), typecheck.nvim integrates smoothly, offering an alternative way to navigate and resolve TypeScript issues.

Credits

typecheck.nvim was inspired by dmmulroy/tsc.nvim, a Neovim plugin that also focuses on asynchronous, project-wide TypeScript type-checking using the TypeScript compiler (tsc). Drawing on its core concept, typecheck.nvim aims to refine and enhance the TypeScript checking experience within Neovim.
