Validator

A tiny schema validation thing for JavaScript Objects.

Install

npm i @scottjarvis/validator

Usage

Add it to your project:

varvalidator=require("@scottjarvis/validator")

Define a schema:

• create the object shape and property names you want
• add the expected type to each property
• or add a function for custom validation

varschema={id: "number",list: "array",name: "string",age: age=>typeofage==="number"&&age>17&&age<130,foo: {baz: "string"}}

Define the object to validate:

varobj={id: 1,name: "bob",age: 300,list: {one: "two"},foo: {bar: "thing"}}

Now lets check obj matches schema

varerrs=validator(obj,schema)//// report the results//if(errs.length<1){console.log("Valid")}else{console.error("Invalid! Errors:",errs)}
