License Neovim version LuaRocks

Demo


A very fast, powerful, extensible and asynchronous Neovim HTTP client written in Lua.

rest.nvim by default makes use of its own curl wrapper made in pure Lua and a tree-sitter parser to parse http files. So what you can run get exact and detailed result what you see from your editor!

In addition to this, you can also write integrations with external HTTP clients, such as the postman CLI.

Important

If you are facing issues, please report them so we can work in a fix together :)

Features

  • Easy to use
  • Friendly, organized and featureful request results window
  • Fast runtime with statistics about your request
  • Set custom pre-request and post-request hooks to dynamically interact with the data
  • Easily set environment variables based on the response to re-use the data later
  • Tree-sitter based parsing and syntax highlighting for speed and perfect accuracy
  • Format response body with native gq command
  • Possibility of using dynamic/environment variables and Lua scripting in HTTP files
  • Save received cookies and load them automatically

Install

Note

rest.nvim requires Neovim >= 0.10.1 to work.

Dependencies

rocks.nvim (recommended)

:Rocks install rest.nvim
:Rocks install tree-sitter-http dev
{
  "rest-nvim/rest.nvim",
}

Note

you also need to install latest tree-sitter-http parser using :TSInstall http

Setup

No .setup() call is needed! Just set your options via vim.g.rest_nvim. It is fully documented and typed internally so you get a good experience during autocompletion :)

---@type rest.Opts
vim.g.rest_nvim = {
    -- ...
}

Note

You can also check out :h rest-nvim.config for documentation.

Usage

Create a new http file or open an existing one and run the :Rest run {name} command, or just place the cursor over the request and simply run :Rest run.

HTTP file syntax

Method Request-URI HTTP-Version
Header-field: Header-value

Request-Body

Note

rest.nvim follows intellij's http client spec for .http file syntax. You can find examples of use in the spec/examples directory.

Keybindings

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

Commands

User Command Behavior
:Rest open Open result pane
:Rest run Run request under the cursor
:Rest run {name} Run request with name {name}
:Rest last Run last request
:Rest logs Edit logs file
:Rest cookies Edit cookies file
:Rest env show Show dotenv file registered to current .http file
:Rest env select Select & register .env file with vim.ui.select()
:Rest env set {path} Register .env file to current .http file

[!INFO] All :Rest subcommands opening new window support command-modifiers (:h command-modifiers.) For example, you can run :hor Rest open to open result pane in horizontal split.

See :h rest-nvim.commands for more info

Lua scripting

http://localhost:8000

# @lang=lua
> {%
local json = vim.json.decode(response.body)
json.data = "overwritten"
response.body = vim.json.encode(json)
%}

Put # @lang=lua comment just above any script elements. Scripts without @lang will be parsed as javascript code to match with http spec.

Extensions

Telescope Extension

rest.nvim provides a [telescope.nvim] extension to select the environment variables file, you can load and use it with the following snippet:

-- first load extension
require("telescope").load_extension("rest")
-- then use it, you can also use the `:Telescope rest select_env` command
require("telescope").extensions.rest.select_env()

Here is a preview of the extension working :)

telescope rest extension demo

Mappings

  • Enter: Select Env file
  • Ctrl + O: Edit Env file

Config

  • config.env.pattern: For env file pattern (lua-pattern)

Lualine Component

We also have lualine component to get what env file you select!

And don't worry, it will only show up under HTTP files.

-- Just add a component in your lualine config
{
  sections = {
    lualine_x = {
      "rest"
    }
  }
}

-- To use a custom icon and color
{
  sections = {
    lualine_x = {
      {
        "rest",
        icon = "๎™‡",
        fg = "#428890"
      }
    }
  }
}

Here is a preview of the component working :)
