# 🛍 (Amazon.in) Price Tracker

JavaScript quickstart project for `amazon.in` price tracking.



  



## Tools

- NodeJs

- Puppeteer

- SendGrid/Mail

- CronJob

## Requirements

In order to utilise this project you need to have the following installed locally:

- nodejs

- npm

- [puppeteer](https://npmjs.com/puppeteer)

- [cheerio](https://npmjs.com/cheerio)

- [sendgrid/mail](https://npmjs.com/sendgrid)

To install the dependencies locally run:

In order for the price tracking to pass, you will need to configure the script with the following parameters:

- Setup/Replace the to and from email addresses in the `sendEmail()` function

```js

function sendEmail(subject, body) {

  const email = {

    to: "*****@yourmail.com",

    from: "*****@yourmail.com",

    subject: subject,

    text: body,

    html: body,

  };

  return sgMail.send(email);

}

```

- Setup/Replace the sendgrid api key from the sendgrid account, and place it locally in a `.env` file.

```text

SENDGRID_API_KEY= *****

```

- Setup/Replace the cron job with desired time interval in the `startTracking()` function

```js

async function startTracking() {

  const page = await configureBrowser();

  let job = new CronJob(

    "* */30 * * * *",

    function () {

      //runs every 30 minutes in this config

      checkPrice(page);

    },

    null,

    true,

    null,

    null,

    true

  );

  job.start();

}

```

## Usage
