# schema-normalizer
## Installation
`npm i @playma256/schema-normalizer --save` or `yarn add @playma256/schema-normalizer -S`
## Motivations
Well, i needed a data normalizer, but a simple one which i could say which properties of something i needed and that would be exported.
So i searched the whole internet seeking for a simple solution, which i could not find.
In a nutshell, this is a normalizer/extracter in steroids.
## How to use it
Given an object, i.e, data.
```javascript
{
prop1: [some array with strings],
prop2: [{prop21: 'teste', prop22: 'teste2'}],
prop4: {
prop41: 'something',
prop42: 'something2'
}
}
```
We would like to extract just prop22 from prop2 and everything from prop4, but we would like to have a prop5, empty string, just for normalization purposes, so how do we do that?
First: we create a "pseudo" schema.
```javascript
export default {
prop2: ['prop22'],
prop4: "*",
prop5: ''
}
```
``` javascript
const normalizer = require('@playma256/schema-normalizer');
const data = {
prop1: [some array with strings],
prop2: [{prop21: 'teste', prop22: 'teste2'}],
prop4: {
prop41: 'something',
prop42: 'something2'
}
};
const finalData = normalizer(schema, data);
```
As a result:
```javascript
console.log(finalData);
>> {
prop2: [{prop22: 'teste2'}],
prop4: {
prop41: 'something',
prop42: 'something2'
},
prop5: ''
};
```
This lib has two wildcards that can be used at the moment:
- \* (asterisk) -> this means, everything from the property.
- ! (optional) -> if it has this value, add, if not, omit.
