# Validating `pricing.json` in Your Editor

This is a quick guide for adding the schema for [`pricing.json`](https://www.tier.run/docs/pricing.json) files to vim and VSCode.

## TL;DR

The schema for `pricing.json` files is available at [https://www.tier.run/docs/pricing.schema.json](https://www.tier.run/docs/pricing.schema.json). Plug that URL into whatever tool you use to validate JSON, and associate it with `pricing.json` files.

## VS Code

More info on editing JSON is available [in the VSCode docs](https://code.visualstudio.com/docs/languages/json).

1. Open the [User and Workspace Settings](https://code.visualstudio.com/docs/getstarted/settings) menu.
    
2. Click `Extensions` and then `JSON` in the left sidebar.
    
3. Look for the option "JSON > Schema Download: Enable" and ensure that the box is checked.
    
4. Underneath that, look for the option "JSON: Schemas" and click "Edit in settings.json"

1. Add the following section:
    
    ```json
    "json.schemas": [
      {
        "fileMatch": ["pricing.json"],
        "url": "https://www.tier.run/docs/pricing.schema.json"
      }
    ],
    ```
    

Here's the result:

## vim/neovim and COC

If you use vim with [COC](https://github.com/neoclide/coc.nvim), you can add support for validating pricing.json files like so:

1. Ensure that `coc-json` is enabled. You can do this by running `:CocInstall coc-json` or by having something like the following in your `~/.vimrc`:
    
    ```plaintext
    let g:coc_global_extensions = ['coc-json']
    ```
    
2. Run `:CocConfig` to option the configuration file for coc. (By default this is `~/.config/nvim/coc-settings.json`.)
    
3. Add the following field to the object there (if it already exists) or add it as a new top level object:
    
    ```json
    {
      "json.schemas": [
        {
          "fileMatch": ["pricing.json"],
          "url": "https://www.tier.run/docs/pricing.schema.json"
        }
      ]
    }
    ```
    

Here's what it looks like in action:

That's it!
