How to define the property file in node js?

Question

I have found an article about properties file reader in node js here: https://www.npmjs.com/package/properties-reader

There is a module as 'properties-reader'. But, I'm unable to understand how to define the property file. Should it be a json?

Answer 1

It's an ini format, as described here:

# contents of properties file
[main]
some.thing = foo

[blah]
some.thing = bar

Answer 2

Its not a Json format, but in ini format.

Steps to set up properties file and to read it from your node module:

1. make any properties file such as app.properties inside your project directory. The file may contain data like:

   \#comment(ignored)
   
   sever.port=3000
   

2. Run the following command to install properties-reader locally:

   npm i properties-reader
   

3. once done use the properties-reader like this:

   const PropertiesReader = require('properties-reader');
   const prop = PropertiesReader('path/to/app.properties');
   
   /*gets property from path/to/app.properties
   You can also export this function using module.exports*/
   getProperty = (pty) => {return prop.get(pty);}
   
   //call the getProperty method
   console.log(getProperty('server.port')); //3000
   

Easy as that!
