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.
{
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.
export default {
prop2: ['prop22'],
prop4: "*",
prop5: ''
}
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:
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.
