Prerequisites

jq installed and available on $PATH
Neovim Treesitter with json module installed
buffer filetype should be json :h filetype

Installation

Using lazy.nvim:

{
    "VPavliashvili/json-nvim",
    ft = "json", -- only load for json filetype
}

Configuration

There is not much needed but I reccomend to use keymaps, otherwise you can ignore this section
For example setup with lazy.nvim like this

{
    "VPavliashvili/json-nvim",
    config = function()
        vim.keymap.set("n", "<leader>jff", '<cmd>JsonFormatFile<cr>')
        vim.keymap.set("n", "<leader>jmf", '<cmd>JsonMinifyFile<cr>')
    end,
}

Usage

These are all the available commands below with usage examples
Commands involving visual mode always should be used with valid json selection
