Visualize The Popularity Of JavaScript Packages With NPM Trends

Developers may use NPM (Node Package Manager) as a package manager for JavaScript packages in their projects. Over 1.5 million packages are available in the NPM registry, which acts as a single location for developers to share and publish their modules. The most widely used package management for JavaScript is NPM, hence it’s important to understand the patterns of package downloads from the NPM registry.

How do NPM Trends work?

NPM trends describe the usage and ubiquity of packages over time in the NPM registry. These patterns may be used to monitor the development and uptake of packages as well as to determine which ones are the most well-liked and often utilised. The number of dependant packages and total downloads are just a few examples of the numerous metrics that can be used to assess NPM trends.

Getting the data

Getting the data for the NPM package you wish to display is the first step. You may get this data by using the NPM trends API. The API gives information on the quantity of packages downloaded during a certain time period. You may use jQuery to send an AJAX call to the API to obtain this data.

    url: '' + packageName,
    type: 'GET',
    success: function(data) {
        var npmTrendData = data;
Plotting the data

Once you have the data, you can use the charting library in the CanvasJS framework to make a chart that shows the trends. A JavaScript library called CanvasJS is used to create charts and graphs. It offers a variety of chart formats and customization possibilities. From the NPM trends data, you must generate an array of datapoints, which you must then send to the chart options along with additional choices such as the chart-title and axis-title.

<div id="chartContainer" style="height: 400px; width: 100%;"></div>
<script type="text/javascript">
var chart = new CanvasJS.Chart("chartContainer", {
    title: {
        text: "NPM Package Download Trends"
    axisY: {
        title: "Downloads"
    data: [{
        type: "line",
        dataPoints: npmTrendData

It’s important to note that the NPM registry gets a lot of requests, therefore rate limitations could be in place to avoid overuse of the API. For further details on usage guidelines and limits, be sure to examine the NPM API documentation.
