rest.nvim

License Neovim version

Features • Install • Usage • Contribute

Demo

A fast Neovim http client written in Lua.

rest.nvim makes use of a curl wrapper made in pure Lua by tami5 and implemented in plenary.nvim so, in other words, rest.nvim is a curl wrapper so you don't have to leave Neovim!

IMPORTANT: If you are facing issues, please report them

Notices

  • 2021-11-04: HTTP Tree-Sitter parser now depends on JSON parser for the JSON bodies detection, please install it too.
  • 2021-08-26: We have deleted the syntax file for HTTP files to start using the tree-sitter parser instead, please see Tree-Sitter parser section for more information.
  • 2021-07-01: Now for getting syntax highlighting in http files you should add a require('rest-nvim').setup() to your rest.nvim setup, refer to packer.nvim. This breaking change should allow lazy-loading of rest.nvim.

Features

  • Easy to use
  • Fast execution time
  • Run request under cursor
  • Syntax highlight for http files and output
  • Possibility of using environment variables in http files

Install

WARNING: rest.nvim requires Neovim >= 0.5 to work.

Dependencies

  • System-wide
    • curl
  • Optional [can be changed, see config bellow]
    • jq (to format JSON output)
    • tidy (to format HTML output)
  • Other plugins

packer.nvim

use {
  "NTBBloodbath/rest.nvim",
  requires = { "nvim-lua/plenary.nvim" },
  config = function()
    require("rest-nvim").setup({
      -- Open request results in a horizontal split
      result_split_horizontal = false,
      -- Keep the http file buffer above|left when split horizontal|vertical
      result_split_in_place = false,
      -- Skip SSL verification, useful for unknown certificates
      skip_ssl_verification = false,
			-- Encode URL before making request
			encode_url = true,
      -- Highlight request on run
      highlight = {
        enabled = true,
        timeout = 150,
      },
      result = {
        -- toggle showing URL, HTTP info, headers at top the of result window
        show_url = true,
        show_http_info = true,
        show_headers = true,
        -- executables or functions for formatting response body [optional]
        -- set them to nil if you want to disable them
        formatters = {
          json = "jq",
          html = function(body)
            return vim.fn.system({"tidy", "-i", "-q", "-"}, body)
          end
        },
      },
      -- Jump to request line on run
      jump_to_request = false,
      env_file = '.env',
      custom_dynamic_variables = {},
      yank_dry_run = true,
    })
  end
}

Tree-Sitter parser

We are using a Tree-Sitter parser for our HTTP files, in order to get the correct syntax highlighting for HTTP files (including JSON bodies) you should add the following into your ensure_installed table in your tree-sitter setup.

ensure_installed = { "http", "json" }

Or manually run :TSInstall http json.

Keybindings

By default rest.nvim does not have any key mappings so you will not have conflicts with any of your existing ones.

To run rest.nvim you should map the following commands:

  • <Plug>RestNvim, run the request under the cursor
  • <Plug>RestNvimPreview, preview the request cURL command
  • <Plug>RestNvimLast, re-run the last request

Settings

  • result_split_horizontal opens result on a horizontal split (default opens on vertical)
  • result_split_in_place opens result below|right on horizontal|vertical split (default opens top|left on horizontal|vertical split)
  • skip_ssl_verification passes the -k flag to cURL in order to skip SSL verification, useful when using unknown certificates
  • encode_url flag to encode the URL before making request
  • highlight allows to enable and configure the highlighting of the selected request when send,
  • jump_to_request moves the cursor to the selected request line when send,
  • env_file specifies file name that consist environment variables (default: .env)
  • custom_dynamic_variables allows to extend or overwrite built-in dynamic variable functions (default: {})

Usage

Create a new http file or open an existing one and place the cursor over the request method (e.g. GET) and run rest.nvim.

NOTES:

  1. rest.nvim follows the RFC 2616 request format so any other http file should work without problems.

  2. You can find examples of use in tests
