SchemaStore.nvim

A Neovim plugin that provides the SchemaStore catalog for use with jsonls and yamlls.

Install

Lazy.nvim:

  "b0o/schemastore.nvim",

Packer:

use "b0o/schemastore.nvim"

Usage

To use SchemaStore.nvim with lspconfig + jsonls:

require('lspconfig').jsonls.setup {
  settings = {
    json = {
      schemas = require('schemastore').json.schemas(),
      validate = { enable = true },
    },
  },
}

For an explanation of why the validate = { enable = true } option is recommended, see #8.

yamlls is also supported:

require('lspconfig').yamlls.setup {
  settings = {
    yaml = {
      schemaStore = {
        -- You must disable built-in schemaStore support if you want to use
        -- this plugin and its advanced options like `ignore`.
        enable = false,
        -- Avoid TypeError: Cannot read properties of undefined (reading 'length')
        url = "",
      },
      schemas = require('schemastore').yaml.schemas(),
    },
  },
}

To use a subset of the catalog, you can select schemas by name (see the catalog for a full list):

require('lspconfig').jsonls.setup {
  settings = {
    json = {
      schemas = require('schemastore').json.schemas {
        select = {
          '.eslintrc',
          'package.json',
        },
      },
      validate = { enable = true },
    },
  },
}

To ignore certain schemas from the catalog:

require('lspconfig').jsonls.setup {
  settings = {
    json = {
      schemas = require('schemastore').json.schemas {
        ignore = {
          '.eslintrc',
          'package.json',
        },
      },
      validate = { enable = true },
    },
  },
}

Note that the select and ignore options are mutually exclusive and attempting to use them together will throw an error.

To replace certain schemas from the catalog with your own:

require('lspconfig').jsonls.setup {
  settings = {
    json = {
      schemas = require('schemastore').json.schemas {
        replace = {
          ['package.json'] = {
            description = 'package.json overridden',
            fileMatch = { 'package.json' },
            name = 'package.json',
            url = 'https://example.com/package.json',
          },
        },
      },
      validate = { enable = true },
    },
  },
}

If you want to include additional schemas, you can use extra:

require('lspconfig').jsonls.setup {
  settings = {
    json = {
      schemas = require('schemastore').json.schemas {
        extra = {
          {
            description = 'My custom JSON schema',
            fileMatch = 'foo.json',
            name = 'foo.json',
            url = 'https://example.com/schema/foo.json',
          },
          {
            description = 'My other custom JSON schema',
            fileMatch = { 'bar.json', '.baar.json' },
            name = 'bar.json',
            url = 'https://example.com/schema/bar.json',
          },
        },
      },
      validate = { enable = true },
    },
  },
}

To use a local schema file, specify the path using the file:// scheme or plain file paths:

require("schemastore").json.schemas({
  extra = {
    {
      description = "Local JSON schema",
      fileMatch = "local.json",
      name = "local.json",
      url = "file:///path/to/your/schema.json", -- or '/path/to/your/schema.json'
    },
  },
})
