nvim-http

You can use this plugin to run HTTP requests directly in your favourite text editor.

This plugin is inspired by the vscode-restclient extension and the IntelliJ HTTP Client.

It is a more advanced alternative to vim-http, but it comes closer to the VSCode and IntelliJ alternatives because of the following features:

1. It supports environment variables.
2. It uses Neovim's async_call mechanism, so the request is not blocking for the editor, and it can be stopped at any time.
3. An extended syntax for the .http files, with support for JSON and HTML blocks in the requests and the responses, as well as comments.
4. Real support for multi-request buffers - it matches the request that surrounds the cursor, while supporting visual selection as well.

Installation

Add the plugin to your Neovim configuration through your favourite plugin manager. For example:

Plug 'BlackLight/nvim-http'

Dependencies

The plugin's core is in Python and it uses the requests library to perform the requests.

The plugin therefore requires:

• The pynvim bindings
  • pip install pynvim
  • On Arch-based distros: [sudo] pacman -S python-pynvim
  • On Debian-based distros: [sudo] apt install python3-pynvim
  • On Red Hat-based distros: [sudo] yum install python-pynvim
• The requests Python library
  • pip install requests
  • On Arch-based distros: [sudo] pacman -S python-requests
  • On Debian-based distros: [sudo] apt install python3-requests
  • On Red Hat-based distros: [sudo] yum install python-requests

Usage

Open a buffer and add the body of your HTTP request. If the file name in the buffer has the .http extension, then the plugin will automatically highlight its syntax, and you can also set up nice automation on the file type.

To run your request:

1. Position the cursor anywhere in the body, or visually select the whole body.
2. Run the :Http command.

The response will be shown in a vsplit buffer.

If you want to interrupt the current request, use the :HttpStop command.

Multiple requests

Like the vim-http, this plugin supports running requests both in normal and in visual mode - in the latter case, only the selected range will be interpreted as a request.

However, like the VSCode and IntelliJ plugins, it also supports multiple requests in the same file in normal mode.

Any line starting with the triple hashtag will be interpreted as a request separator:

### The first request

POST {{base_url}}/api/v1/users HTTP/1.1
Authorization: Bearer {{jwt_token}}

{
  "name": "Alice"
}

### The second request

GET {{base_url}}/api/v1/users?name=Alice HTTP/1.1
Authorization: Bearer {{jwt_token}}

### ...more requests

When :Http is run in normal mode, it will detect the boundaries of the surrounding request and only execute that request.

Environment files

This plugin is compatible with environment files generated by the VSCode extension. Any file matching the *.env.json pattern stored in the same folder as the .http file (or the current working directory) will be interpreted as an environment file. Example format:

{
  "dev": {
    "base_url": "http://localhost:3000",
    "jwt_token": null
  },
  "prod": {
    "base_url": "https://foobar.eu-west.some-cloud.com",
    "jwt_token": "SECRET"
  }
}

If multiple environment files are detected, or there are files with more than one environment, then the :Http command will prompt the user for which environment they want to use before executing the request.

The environment variables can then be wrapped as {{varname}} in the buffer:

GET {{base_url}}/api/v1/users?limit=10
Authorization: Bearer {{jwt_token}}
