How can I run an example of npm

Question

Here is a nice example on how to convert a complete json to csv.

I installed the program using npm install json-2-csv

I tried to take a run at the example. I made a js file but I can't run it. How can I run it to see in action how it works?

It is the example provided for json-2-csv 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>

Is it possible to give an example on how to be my js file because I newbie to web development use? — Robbbbbi, Jan 28 '15 at 19:39

Assuming you have node and npm installed...

You need to forget about the HTML markup. That's what node is complaining about.

Create a folder called something like example.
In that folder, run npm install json-2-csv.
Create a file called example.js and paste in the following. Basically, just the script from 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 in that folder.
In that folder, run node example.js.

That's it! The program will print out the data in CSV format.

Hey it works with your steps. Thank you. Can I write this data from console csv to a csv file? — Robbbbbi, Jan 28 '15 at 20:01
There are multiple ways to do this, but the easiest is just run `node example.js > output.csv`. — Brent Rockwood, Jan 28 '15 at 21:30

Assuming your file is called myFile.js, run the following from terminal in the same directory as your JS file:

node myFile.js

This assumes you've installed NodeJS which you can install from NodeJS.org.

Yes I got the nodejs but when I run the command it gives me back SyntaxError: Unexpected token < Could be possible to provide a full example? How my js file have to be, what steps should I do and how to save the results to a new csv file? – Robbbbbi Jan 28 '15 at 19:20
Can you post your JS code so we can look at it? Tough to see your syntax error without. – Brant Jan 28 '15 at 19:22
