Sanitizers

Here is a list of the sanitizers currently available.

Sanitizer | Description -------------------------------------- | ------------------------------- blacklist(input, chars) | remove characters that appear in the blacklist. The characters are used in a RegExp and so you will need to escape some chars, e.g. blacklist(input, '\\[\\]'). escape(input) | replace <, >, &, ', " and / with HTML entities. ltrim(input [, chars]) | trim characters from the left-side of the input. normalizeEmail(email [, options]) | canonicalize an email address. (This doesn't validate that the input is an email, if you want to validate the email use isEmail beforehand).options is an object with the following keys and default values:all_lowercase: true - Transforms the local part (before the @ symbol) of all email addresses to lowercase. Please note that this may violate RFC 5321, which gives providers the possibility to treat the local part of email addresses in a case sensitive way (although in practice most - yet not all - providers don't). The domain part of the email address is always lowercased, as it is case insensitive per RFC 1035.gmail_lowercase: true - Gmail addresses are known to be case-insensitive, so this switch allows lowercasing them even when all_lowercase is set to false. Please note that when all_lowercase is true, Gmail addresses are lowercased regardless of the value of this setting.gmail_remove_dots: true: Removes dots from the local part of the email address, as Gmail ignores them (e.g. "john.doe" and "johndoe" are considered equal).gmail_remove_subaddress: true: Normalizes addresses by removing "sub-addresses", which is the part following a "+" sign (e.g. "[email protected]" becomes "[email protected]").gmail_convert_googlemaildotcom: true: Converts addresses with domain @googlemail.com to @gmail.com, as they're equivalent.outlookdotcom_lowercase: true - Outlook.com addresses (including Windows Live and Hotmail) are known to be case-insensitive, so this switch allows lowercasing them even when all_lowercase is set to false. Please note that when all_lowercase is true, Outlook.com addresses are lowercased regardless of the value of this setting.outlookdotcom_remove_subaddress: true: Normalizes addresses by removing "sub-addresses", which is the part following a "+" sign (e.g. "[email protected]" becomes "[email protected]").yahoo_lowercase: true - Yahoo Mail addresses are known to be case-insensitive, so this switch allows lowercasing them even when all_lowercase is set to false. Please note that when all_lowercase is true, Yahoo Mail addresses are lowercased regardless of the value of this setting.yahoo_remove_subaddress: true: Normalizes addresses by removing "sub-addresses", which is the part following a "-" sign (e.g. "[email protected]" becomes "[email protected]").icloud_lowercase: true - iCloud addresses (including MobileMe) are known to be case-insensitive, so this switch allows lowercasing them even when all_lowercase is set to false. Please note that when all_lowercase is true, iCloud addresses are lowercased regardless of the value of this setting.icloud_remove_subaddress: true: Normalizes addresses by removing "sub-addresses", which is the part following a "+" sign (e.g. "[email protected]" becomes "[email protected]"). rtrim(input [, chars]) | trim characters from the right-side of the input. stripLow(input [, keep_new_lines]) | remove characters with a numerical value < 32 and 127, mostly control characters. If keep_new_lines is true, newline characters are preserved (\n and \r, hex 0xA and 0xD). Unicode-safe in JavaScript. toBoolean(input [, strict]) | convert the input string to a boolean. Everything except for '0', 'false' and '' returns true. In strict mode only '1' and 'true' return true. toDate(input) | convert the input string to a date, or null if the input is not a date. toFloat(input) | convert the input string to a float, or NaN if the input is not a float. toInt(input [, radix]) | convert the input string to an integer, or NaN if the input is not an integer. trim(input [, chars]) | trim characters (whitespace by default) from both sides of the input. unescape(input) | replace HTML encoded entities with <, >, &, ', " and /. whitelist(input, chars) | remove characters that do not appear in the whitelist. The characters are used in a RegExp and so you will need to escape some chars, e.g. whitelist(input, '\\[\\]').

XSS Sanitization

XSS sanitization was removed from the library in 2d5d6999.

For an alternative, have a look at Yahoo's xss-filters library or at DOMPurify.
