Validate, sanitize and assert: the silver bullet of data!

Beta version.

/!\ This documentation is still a Work In Progress /!\

Basic validation

• sanitize Array of string the sanitizer's name to apply before any type checking
• optional boolean the data can be null or undefined, if so the data validate immediately
• default (anything) the data can be null or undefined, if so it is overwritten by the default value and it validates immediately
• type string the name of the type checker
• instanceOf
• min
• max
• length
• minLength
• maxLength
• match
• in
• notIn
• when
• properties object of schema, it iterates through each properties and checks that they all match their own schema
• elements Array same than properties but for arrays
• only boolean used in conjunction with properties or elements, it checks that no properties other than those listed are present
• of object contains one schema that will check each elements of an array or each properties

Type Checkers

Javascript primitive types:

• undefined: the data should be undefined
• null: the data should be null
• boolean: the data should be a boolean, i.e. true or false
• number: the data should be a number. NOTE that Infinity and NaN are ok, so you may consider using real/float instead of number in almost all cases
• string: the data should be a string
• object: the data should be an Object
• function: the data should be a Function

Javascript/Node.js built-in types:

• array: the data should be an Array
• error: the data should be an instance of Error
• date: the data should be an instance of Date
• regexp: a regular expression
• buffer: the data should be a Node.js Buffer

Common meta types:

• unset: null or undefined
• real or float: a number that is not NaN nor +/- Infinity
• integer: a number that is not NaN nor +/- Infinity, and that do not have decimal part
• hex: a string representing an hexadecimal number, having only 0-9, a-f and A-F characters
• strictObject: an object that is not an array
• looseObject: object-like: object or function

Internet:

• ipv4: a string that is a IPv4 address
• ipv6: a string that is a IPv6 address
• ip: an IPv4 or IPv6 address
• hostname: a string that is a valid hostname (domain + subdomain)
• host: a hostname or an ip address
• url: a string that is a valid URL (generic URL) including the scheme
• weburl: a valid web/internet URL, a subset of the URL type
• email: a string that is a valid email address

Misc:

• schema: an object which is a valid @teamteanpm2024/tempora-consectetur-dolores schema
• mongoId: an object which is a MongoDB's ObjectId OR a string that is a correct ObjectId string representation

Sanitizers

Common cast:

• toNumber: try to convert to a number (mostly from string)
• toReal or toFloat: try to convert to a float/real (not much difference with toNumber)
• toInteger: try to convert to an integer, rounding the number if necessary
• toString: try to convert to a string
• toBoolean: try to convert to a boolean very loosely, so it accepts strings like true/false, yes/no, on/off or numbers like 1/0, or fallback to truthy/falsy values.
• toArray: try to convert to an array, non-array are converted to an array with a single element
• toDate: try to convert to a Date (number are timestamp, string are parsed, object are considered like a Date-object)
• nullToUndefined: transform null to undefined

String modifiers:

• trim: trim the string, removing whitespace at the beginning and the end
• toUpperCase: transform all characters into their upper-case counterparts
• toLowerCase: transform all characters into theier lower-case counterparts
• capitalize: transform to title case, each word starts with an upper-case
• titleCase: transform to title case, each word starts with an upper-case following lower-case characters (except ALL-CAPS words)
• latinize: transform letter to latin (remove accent, transform modified letters to their latin counterparts)
• dashToCamelCase: transform identifiers having word separated by dash/hyphen to camelCase

Enforcers:

• resize: resize a string if it does not match the required length/minLength/maxLength (truncate, or use leftPadding/rightPadding properties of the schema)
• removeExtraProperties: remove extra-properties from the object that are not in the schema (clone it, not in-place)

Misc:

• mongoId: convert a string to a MongoDB's ObjectId if possible
