Happy-chappy is a compact, dependency-free JSON object validator package for JavaScript and TypeScript.
import { Schema, createValidator, validate } from "happy-chappy";
const MY_OBJECT_SCHEMA: Schema = {
object: {
members: {
firstField: "number",
secondField: {
number: {},
optional: true
},
thirdField: "string",
fourthField: {
enum: [1, 2, 3, "four", 5]
}
}
}
};
const validateMyObject = createValidator(MY_OBJECT_SCHEMA);
const myObject = { firstField: 5, thirdField: "hey", fourthField: "four" };
validateMyObject(myObject) === true;
// Or alternatively
validate(myObject, MY_OBJECT_SCHEMA) === true;
Many more examples available in the test folder.
Supported data types are:
Each of these can be further restricted using matcher functions or specific configuration.
Text string validation is supported using multiple types of matcher. A string can be matched by:
Number validation options allow to restrict the available range as follows:
Arrays can be further scoped by setting the following:
Object specification can be customised by allowing extra memebrs not to be taken into account during validation or by specifying a matcher function.
Enumerated values can be any string or number, matched with the strict equality operator.
Matchers allow more complex logic to be included in the validation model. For example:
const isPersonWithAgeTuple = (v: any[]) => (
v.length === 2
&& typeof v[0] === "string"
&& typeof v[1] === "number"
&& Number.isInteger(v[1])
); // Enforces [Name: string, Age: integer]
const schema: Schema = {
array: { matcher: isPersonWithAgeTuple }
};
validate(["Dummy", 5], schema) === true;
validate([5, "Dummy"], schema) === false;
Version 2 brings in typing aids for objects and enumerations to streamline the schema ceration process. When you define a schema for an object or enumeration you can provide a type that will be used to assist in constraining object members and enumerated values.
interface MyRequest {
a: number
b: string
}
const MY_REQUEST_SCHEMA: Schema<MyRequest> = {
object: {
members: {
a: { ... },
b: { ... },
c: { ... }, // TypeScript error!
}
}
};
enum MyEnum {
first = 1,
second = 2
}
const MY_REQUEST_SCHEMA: Schema<MyEnum> = {
enum: [
MyEnum.first,
2,
3 // TypeScript error!
]
};
type MyEnum = "first" | "second";
const MY_REQUEST_SCHEMA: Schema<MyEnum> = {
enum: [
"first",
"second",
"third" // TypeScript error!
]
};
