What steps should I take to execute a npm demonstration?

Here, you can find a great example of how to convert a full JSON file into a CSV format.

To make it work, I downloaded the json-2-csv program by running the command npm install json-2-csv

After setting up my JavaScript file with the example code, I encountered some issues running it. Can anyone provide guidance on how to execute it and see it in action?

This script is taken from the json-2-csv documentation page.

<!DOCTYPE html>
<html>
    <head>
        <meta charset="utf-8"/>
        <title> </title>
    </head>

    <body>

    <script>
    var converter = require('json-2-csv');

var documents = [
    {
        Make: 'Nissan',
        Model: 'Murano',
        Year: '2013',
        Specifications: {
            Mileage: '7106',
            Trim: 'S AWD'
        }
    },
    {
        Make: 'BMW',
        Model: 'X5',
        Year: '2014',
        Specifications: {
            Mileage: '3287',
            Trim: 'M'
        }
    }
];

var json2csvCallback = function (err, csv) {
    if (err) throw err;
    console.log(csv);
};

converter.json2csv(documents, json2csvCallback);

    </script>

    </body>

</html>

To start, ensure you have node and npm installed on your system.

Forget about the HTML markup for now, as that is what is causing the error with node.

  • First, create a new directory with a name like example.
  • Inside that directory, use the command npm install json-2-csv to install the necessary package.
  • Next, create a new file named example.js and paste in the script provided in your question.

var converter = require('json-2-csv');

var documents = [
    {
        Make: 'Nissan',
        Model: 'Murano',
        Year: '2013',
        Specifications: {
            Mileage: '7106',
            Trim: 'S AWD'
        }
    },
    {
        Make: 'BMW',
        Model: 'X5',
        Year: '2014',
        Specifications: {
            Mileage: '3287',
            Trim: 'M'
        }
    }
];

var json2csvCallback = function (err, csv) {
    if (err) throw err;
    console.log(csv);
};

converter.json2csv(documents, json2csvCallback);

  • Save the file within the directory you created.
  • From the command line in that directory, run node example.js.

And that's all there is to it! The program will now display the data in CSV format.
