Install

[!WARNING] Requirements:

• Neovim 0.10.0+
• Treesitter
• nvim-cmp

Via lazy.nvim:

require('lazy').setup({
  -- GraphQL completion
  {
    'mistweaverco/kulala-cmp-graphql.nvim',
    opts = {},
  },
})

Configuration

Add the following to your cmp.setup:

cmp.setup.filetype("http", {
  sources = cmp.config.sources({
    { name = "kulala-cmp-graphql" },
  }, {
    { name = "buffer" },
  }),
})

Full Configuration

A full configuration example using lazy.nvim:

-- Bootstrapping lazy.nvim
local lazypath = vim.fn.stdpath("data") .. "/lazy/lazy.nvim"
if not vim.loop.fs_stat(lazypath) then
  vim.fn.system({
    "git",
    "clone",
    "--filter=blob:none",
    "https://github.com/folke/lazy.nvim.git",
    "--branch=stable", -- latest stable release
    lazypath,
  })
end
vim.opt.rtp:prepend(lazypath)

Usage

This plugin provides completions for GraphQL queries in .http/.rest files.

It depends on a GraphQL schema file in your project which should reside next to your .http/.rest files.

The schema file should be named [http-file-name-without-extension].graphql-schema.json or graphql-schema.json.

You can download the schema file using kulala.nvim via the :lua require("kulala").download_graphql_schema()
