Module resty.ljsonschema.metaschema

Metaschema for JSON Schema Draft 4.

This module returns the metaschema for draft 4 as a Lua table.

Usage:

-- create a validator for the metaschema which doesn't require array_mt.

local metaschema = require("resty.ljsonschema.metaschema")
local schema_as_lua_table_validator = jsonschema.generate_validator(metaschema, {
  array_mt = false,
})

-- Define a JSONschema in a Lua table
local schema = {
  type = "object",
  properties = {
    key = {
      oneOf = {   -- NOTE: this is an array, it would fail with `jsonschema.jsonschema_validator`.
        { type = "string" },
        { type = "integer" },
      }
    }
  }
}

-- Validate the schema against the metaschema to check it is a valid Draft 4 schema
assert(schema_as_lua_table_validator(schema))
