Validation

Validate data structures against a schema-like definition.

• solidb.validate(data, rules) -> bool, error
  Returns true if valid, or false and an error message.
  
  Rules:

  • type: "string", "number", "boolean", "table", "email", "uuid"
  • required: boolean
  • min, max: number (for numbers) or length (for strings)
  • matches: regex string

local valid, err = solidb.validate(request.body, {
  name = { type = "string", required = true, min = 3 },
  age = { type = "number", min = 18 },
  email = { type = "email" }
})

if not valid then
  response.status = 400
  return { error = err }
end

• solidb.sanitize(str) -> string
  Simple wrapper to strip HTML tags.
• solidb.escape_html(str) -> string
  Convert special characters to HTML entities.
