Convert Java .properties files to JSON (using JavaScript).

supports array creation.

The function propertiesToJSON takes a string and returns a JavaScript object.

use

 propertiesToJSON(data, {
                jsonAsString: false,
                convertToJsonTree : false,
                parseNumber:false,
                parseBooleanNullUndefined:false,
            });

Read a local file in node:

const fs = require('fs');
const path = require('path');
const filePath = path.join(__dirname, 'sample.properties');
const propertiesToJSON = require('properties-to-json');;

fs.readFile(filePath, { encoding: 'utf-8' }, (err, data) => {
    if (!err) {
        console.log(propertiesToJSON(data));
    }
});

Read a remote file in the browser:

import propertiesToJSON from 'js-properties-to-json';

const propsFile = new Request('<link-to-properties-file>');

const props = fetch(propsFile)
    .then((response) => {
        return response.text();
    })
    .then((text) => {
        const propsText = propertiesToJSON(text);
        console.log(propsText);
        return propsText;
    });
