Validata Mongo

Type safe data validation and sanitization for MongoDB update $set operations
using validata.

See validata for more details on validation functionality.

Getting started

``bash
npm i validata validata-mongo
`

Basic usage

Given interfaces

`typescript
interface MyObject {
required: string;
optional?: string;
child: Child;
}

interface Child {
foo: number;
bar: number;
}
`

And validata

`typescript
const myCheck = isObjectSet({
required: isString(),
optional: maybeString(),
child: isObjectSet({
foo: isNumber({ min: 1 }),
bar: asNumber({ coerceMax: 10 }),
}),
});
`

Then

`typescript
const result = check(myCheck, () => ({
required: 'blue',
child: {
foo: 1,
bar: 2,
},
}));
console.log(JSON.stringify(result));
// -> SUCCESS -> {"required":"blue","child":{"foo":1,"bar":2}}

const result = check(myCheck, () => ({
required: 'blue',
optional: 'red',
child: {
foo: 20,
bar: '20',
},
}));
console.log(JSON.stringify(result));
// -> SUCCESS -> {"required":"blue","optional":"red","child":{"foo":20,"bar":10}}
// NOTE child.bar has been converted to a number and coerced to a max of 10

const result = check(myCheck, () => ({
required: 'blue',
'child.foo': 3,
}));
console.log(JSON.stringify(result));
// -> SUCCESS -> {"required":"blue","child.foo":3}

const result = check(myCheck, () => ({
required: 'blue',
'child.bar': '73',
}));
console.log(JSON.stringify(result));
// -> SUCCESS -> {"required":"blue","child.bar":10}
// NOTE child.bar has been converted to a number and coerced to a max of 10

check(myCheck, () => ({
wow: 'blue',
}));
// -> ERROR -> {"issues":[{"path":["wow"],"value":"blue","reason":"unexpected-property"}],"name":"ValidationError"}

check(myCheck, () => ({
required: 'blue',
'child.unexpected': 17,
}));
// -> ERROR -> {"issues":[{"path":["child.unexpected"],"value":17,"reason":"unexpected-property"}],"name":"ValidationError"}
