JavaScript Semantic Data Types

Or if you're using npm:

npm install @kitmi/types

Conventions

Types

• any
• array
• bigint
• binary
• boolean
• datetime
• integer
• number
• object
• text

Type Interface

name: "type name",
alias: ["type alias"],
defaultValue: null,

sanitize: (value, meta, i18n, context) => sanitized,
serialize: (value, meta) => string

Common Type Meta

• {boolean} plain - Keep raw value, don't try to type cast before post processing
• {boolean} optional - No error throw if value is null and default is null
• {any} default - Default value if value is null
• {array} enum - An array of values which the value of a enumerable type should be one of it

Enumerable Types

• bigint
• integer
• number
• text

Validation Error

• message
• status = 400
• code = E_INVALID_DATA
• info = { value, meta, [i18n], [path] }

Plugins

• datetimeParser
• bigintWriter
• preProcess - [sync/async] (value, meta, opts: { rawValue, i18n, path }) => [ finished, processedValue ] or [ false ]
• postProcess - [sync/async] (value, meta, opts: { rawValue, i18n, path }) => processedValue

Note: if preProcess or postProcess is async function, sanitize_ should be called instead of sanitize

See @kitmi/validators for semantic validation.

Notes

• Object sanitization

Use keepUnsanitized for keeping those entries not defined in the object schema.
