JSON validating libraries for promise chains
I'm looking at ways of marshalling/validating what gets transported through a javascript promise chain. I first looked at Typescript, but after a tip from a friend now looking at JSON schema validators and similar. These are the ones I'm looking at right now:
bugventure/jsen: JSON-Schema validator built for speed
A custom format validator can be specified as:
- a regular expression
string- a regular expression
object- a
function (value, schema)that must return a truthy value if validation passes
epoberezkin/ajv: The fastest JSON schema Validator
.addFormat(String name, String|RegExp|Function|Object format)
Add custom format to validate strings. It can also be used to replace pre-defined formats for ajv instance.
Strings are converted to RegExp.
Function should return validation result as
trueorfalse.
exjs/exmodel: Extensible data model - high performance data processing, schema builder, validator, and sanitizer.
Lots of built-in types and also has regex. No custom types.
pandastrike/jsck
No regular expressions, no custom types afaict.
The above ones are selected a bit for speed, but I will focus on the ones that are most flexible with custom types, allowing both regular expressiosn and functions as validators, and which ones have a nice syntax. Remains to be evaluated.
