Data & parameter sanitizer

Every document that goes to the database needs to be sanitized first. This is to ensure that the document is properly saved according its schema definition.

If schema collection is provided (i.e: attributes isn't empty), then on every create() and update() operation the body parameter is automatically sanitized:

  1. According to its type: boolean, date, datetime, float, and integer will automatically sanitized using its related sanitizer.

  2. According to its sanitizer definition below.

  3. You can put one or more sanitizer on every attributes. Sanitizers put manually on attributes will override the one automatically provided according to its type.


name: 'users',
attributes: {
username: {
type: 'string',
sanitizer: {
trim: true,
blacklist: '12345'
name: {
type: 'string',
sanitizer: {
trim: true
gender: {
type: 'boolean'
birth_date: {
type: 'date',
sanitizer: {
toDate: 'YYYY-MM-DD'
email: {
type: 'string',
sanitizer: {
normalizeEmail: {
all_lowercase: false

From the example above:

  • username will be trimmed from whitespace and accept any character except 1, 2, 3, 4 and 5

  • name will be trimed from whitespace

  • gender will be converted using toBoolean sanitizer

  • birth_date will be parsed using YYYY-MM-DD pattern

  • email will be sanitized using normalizeEmail with custom options

If error occurs, or value doesn't match the provided pattern, value will be converted to null
