It is a helper method to inject values in json attributes

Scenery

If you have a default json template stored in your database and your application needs to replace some values to let it dynamic, you can use this to help you.

How to use

This is a simple usage

const injectByKeyValuePairs = require('inject-values-in-json');

// it can be a json string as well
const json = {
  title: 'About ${subject}',
  content: 'Dear ${name}, <br />I am contacting you because... <br />This is my phone number ${phone}',
  sent: '${date}'
};

const keyValuePairs = {
  name: 'Jhon',
  subject: 'Something',
  phone: '202-555-0175',
  date: new Date()
};

injectByKeyValuePairs(json, keyValuePairs);

// output
/*
{
  title: 'About Something',
  content: 'Dear Jhon, <br />I am contacting you because... <br />This is my phone number 202-555-0175',
  sent: '2019-05-18T01:58:54.983Z'
}
*/

You can use functions as well

const json = {
  title: 'I want to generate some random ids for ${name}s products',
  products: [
    { id: '${id}', name: 'skate' },
    { id: '${id}', name: 'bicycle' },
    { id: '${id}', name: 'computer' },
    { id: '${id}', name: 'cellphone' }
  ]
};

const keyValuePairs = {
  name: 'Jhon',
  id: () => Math.random().toString(36).substring(7)
};

injectByKeyValuePairs(json, keyValuePairs);

// output
/*
{
  title: 'I want to generate some random ids for Jhons products',
  products:
   [
     { id: 'e6rdq', name: 'skate' },
     { id: '02xaq', name: 'bicycle' },
     { id: 'cs45v', name: 'computer' },
     { id: '6d6cfn', name: 'cellphone' }
   ]
}
