When we're ready for people to start using this language server, we'll want to add it to lspconfig and Mason to make setup as easy as possible. For now, installation is manual.

First checkout this repo locally and run npm install. Then you can configure Neovim to use that checkout to run the server. The following is my configuration, yours may vary slightly depending on your environment.

WARNING: Node.js v20.13.0 or higher is required because of a bug in node.js that was fixed in that version.

~/.config/nvim/ftplugin/json.lua

local root_files = { ".git", "package.json" }
local paths = vim.fs.find(root_files, { stop = vim.env.HOME })

vim.lsp.start({
  name = "hyperjump-json-schema",
  cmd = { "node", "/path/to/json-schema-language-tools/language-server/src/server.js", "--stdio" },
  root_dir = vim.fs.dirname(paths[1]),
  -- settings = {
  --   jsonSchemaLanguageServer = {
  --     -- Put any settings here
  --   }
  -- }
})
